Maltese Fever

Maltese fever is an infection in humans caused by Brucella bacteria. These germs live mainly in animals such as goats, sheep, cows, pigs, and dogs. People get infected when they drink raw (unpasteurized) milk or eat soft cheeses made from infected animals, breathe in tiny droplets at work (for example, in a lab or slaughterhouse), or touch animal blood, tissues, or placenta without protection. The illness can start like the flu, with fever, body aches, and heavy sweating at night. It may last weeks to months and can come and go (this is why it’s also called “undulant fever”). Without treatment it can settle in one body part, like the spine, joints, heart, liver, or nervous system. World Health Organization+2CDC+2

Maltese fever (brucellosis) is a bacterial infection caused by Brucella germs that live in animals such as cows, goats, sheep, pigs, dogs, and wildlife. People usually get it by drinking raw (unpasteurized) milk or eating soft cheeses made from raw milk, or by direct contact with birth products, blood, urine, or tissue of infected animals. Doctors confirm it with blood tests and then treat it with a combination of antibiotics for at least 6–8 weeks to prevent relapse, because this germ can hide inside body cells. Serious, but less common, complications include infections of the heart valves (endocarditis), bones and joints (spondylitis), liver abscesses, and the nervous system. Avoiding raw dairy and using protective equipment around animals can prevent most cases.

Other names

Maltese fever is also known as brucellosis, undulant fever, Mediterranean fever, and Malta fever. All these terms describe the same human illness caused by Brucella infection, which classically spread through unpasteurized goat and sheep dairy products in the Mediterranean region. Wikipedia

Types

Acute brucellosis. Symptoms start within days to a few weeks. Fever, chills, night sweats, headache, muscle and joint pains are common. Early blood tests or cultures may still be positive. NCBI+1

Subacute brucellosis. Symptoms continue beyond a few weeks. People feel tired, lose weight, and have ongoing aches. Blood tests may show inflammation and antibody levels rising between samples. CDC

Chronic brucellosis. Symptoms last for months. Fatigue and pain dominate. The germ may hide inside cells, so the illness can relapse after seeming better. PMC

Relapsing brucellosis. Symptoms improve, then come back. This can happen even after correct treatment and is part of the natural course of the disease in some people. PMC

Localized (focal) brucellosis. The infection focuses on one organ—commonly bones and joints (sacroiliitis, spondylitis), the genitourinary tract (epididymo-orchitis), the liver or spleen, the heart (endocarditis), or the nervous system (neurobrucellosis). These forms cause organ-specific symptoms. NCBI+1

Occupational brucellosis. People in high-risk jobs—farmers, veterinarians, slaughterhouse workers, and lab staff—get exposed at work through contact or aerosols. woah.org

Food-borne brucellosis. Infection follows eating or drinking unpasteurized dairy or undercooked animal products from infected animals. World Health Organization

Laboratory-acquired brucellosis. Brucella is easily aerosolized and has a very low infectious dose, so lab exposures can cause outbreaks if biosafety steps are missed. CDC

Causes

1. Raw milk. Drinking unpasteurized milk from infected animals is a leading route. Pasteurization kills Brucella. World Health Organization

2. Soft cheeses. Fresh cheeses made from unpasteurized goat or sheep milk can carry the bacteria. World Health Organization

3. Raw or undercooked meat or organ meat. Eating undercooked animal products from infected livestock may transmit infection. health.vic.gov.au

4. Animal birthing products. Contact with placenta, fetal membranes, or aborted fetuses can expose you to very high bacterial loads. health.vic.gov.au

5. Animal blood and tissues. Handling carcasses or butchering without gloves increases risk. woah.org

6. Workplace aerosols. Breathing contaminated dust or droplets in abattoirs or labs can cause infection. CDC

7. Veterinary work. Treating or vaccinating livestock exposes vets to splashes and needle injuries. woah.org

8. Slaughterhouse work. Knife cuts, splashes, and aerosols during processing are typical exposure paths. woah.org

9. Farming and herding. Daily contact with infected herds or flocks raises risk, especially during kidding or lambing seasons. woah.org

10. Handling infected dogs. Brucella canis can infect humans; breeders and kennel workers may be at risk. Wikipedia

11. Hunting feral swine. Wild pigs can carry B. suis; hunters get exposed when dressing carcasses. CDC

12. Travel to endemic regions. Eating local unpasteurized dairy during travel can lead to infection. World Health Organization

13. Occupational lab exposure. Accidental culture handling outside a biosafety cabinet can lead to infection clusters. CDC

14. Household food sharing. Families sharing the same raw dairy source can all be exposed. World Health Organization

15. Animal vaccination accidents. Self-injection with live animal vaccine strains has caused human disease. Wikipedia

16. Contaminated dust or soil. In areas with animal abortions, dried material can become airborne and inhaled. woah.org

17. Organ transplantation (rare). Donor infection has rarely transmitted Brucella. Clinicians screen suspicious cases. (inferred from clinical reviews) PMC

18. Transplacental spread (rare). Pregnant people with brucellosis can pass infection to the fetus. PMC

19. Breastfeeding (rare). Brucella has been detected in breast milk during maternal infection; clinicians weigh risks. (review evidence) PMC

20. Blood exposure (rare). Needle sticks or transfusion from an infected donor are unusual but possible. (review evidence) PMC

Symptoms

1. Fever that rises and falls. Temperature may go up in the evening and fall by morning, creating an “undulant” pattern. Wikipedia

2. Night sweats. Sweats can be heavy and drenching. Some people notice a musty or “hay-like” smell. Wikipedia

3. Extreme tiredness. Fatigue is common and may last long after fever improves. PMC

4. Headache. Often with light sensitivity or neck stiffness if the nervous system is involved. PMC

5. Muscle aches. General body aches reflect whole-body inflammation. Wikipedia

6. Joint pain. Knees, hips, ankles, and the sacroiliac joints (low back/pelvis) are common targets. NCBI

7. Back pain. Pain may signal infection of the spine (spondylitis or discitis). NCBI

8. Loss of appetite and weight loss. Ongoing inflammation can reduce appetite over time. Wikipedia

9. Abdominal discomfort. The liver and spleen can enlarge and feel sore. NCBI

10. Testicular pain or swelling in men. This suggests epididymo-orchitis from localized infection. NCBI

11. New heart murmur or chest symptoms (rare). Endocarditis is uncommon but the most dangerous complication. NCBI

12. Nerve or brain symptoms (rare). Confusion, weakness, or seizures can occur in neurobrucellosis. PMC

13. Cough or chest pain (occasional). Lung involvement is uncommon but possible, especially after aerosol exposure. PMC

14. Low mood or irritability. Long illness and inflammation can affect mental health. PMC

15. Long relapsing course. Symptoms may improve then recur if bacteria persist inside cells. PMC

Diagnostic tests

A) Physical examination (bedside checks)

1. Temperature charting. Recording fever patterns helps recognize the “undulant” evening spikes that fit brucellosis. It also tracks response to therapy. Wikipedia

2. Lymph node check. Doctors feel for enlarged, tender nodes in the neck, armpits, or groin, which signal immune activity. NCBI

3. Liver and spleen exam. Gentle pressing under the ribs can detect enlargement (hepatosplenomegaly), common in systemic infection. NCBI

4. Spine and sacroiliac palpation. Pressing along the spine and sacroiliac joints can locate focal bone or joint infection that needs imaging. NCBI

5. Heart auscultation. Listening for a new murmur may suggest endocarditis, which needs urgent imaging and blood cultures. NCBI

6. Genital exam in men. Swollen, tender testis and epididymis with redness point to epididymo-orchitis from localized brucellosis. NCBI

B) Manual tests (simple bedside maneuvers)

7. Sacroiliac stress maneuvers (e.g., FABER). Gentle hip movements that stress the sacroiliac joint can reproduce pain and support sacroiliitis from brucellosis, prompting MRI. (orthopedic maneuvers applied to focal disease) NCBI

8. Spinal percussion test. Light tapping over vertebrae that triggers focal pain raises concern for brucellar spondylitis or discitis and guides imaging. NCBI

9. Abdominal percussion and palpation. Detects tender enlarged liver or spleen, helping localize disease before ultrasound. NCBI

10. Neurologic bedside screen. Simple checks of strength, sensation, reflexes, and gait can unmask neurobrucellosis and guide CSF testing and MRI. PMC

C) Laboratory and pathological tests

11. Blood culture. Detects Brucella directly in the bloodstream. It can take time to grow, and careful lab biosafety is essential because very few bacteria are needed to infect staff. PMC+1

12. Bone marrow culture. Often more sensitive than blood culture, especially after antibiotics, because bacteria may hide in the bone marrow. PMC

13. Standard agglutination test (SAT). A common antibody test; rising titers between two blood samples 2–4 weeks apart support acute infection. CDC

14. ELISA (IgM/IgG). Detects early (IgM) and ongoing or past (IgG) immune responses; useful when cultures are negative. PMC

15. Coombs (antiglobulin) anti-Brucella test. Helps when blocking antibodies interfere with standard tests, especially in long-standing cases. weekly.chinacdc.cn

16. PCR for Brucella DNA. Molecular test that finds bacterial genetic material in blood or other fluids; helpful for early diagnosis or focal disease. PMC

17. Liver tests (ALT, AST, ALP). Elevated enzymes suggest liver involvement, which is common in systemic brucellosis. PMC

18. Inflammation markers (ESR, CRP). These rise with active infection and help track improvement, though they are not specific. PMC

19. Cerebrospinal fluid (CSF) analysis. If there are neurologic signs, lumbar puncture can show inflammation, and culture/PCR may confirm neurobrucellosis. PMC

20. Urine or semen cultures (select cases). If urinary or reproductive symptoms occur, cultures or PCR from these fluids can confirm focal infection. PMC

D) Electrodiagnostic tests (electrical recordings when specific complications are suspected)

21. Electrocardiogram (ECG). Looks for rhythm problems or signs of myocarditis or endocarditis complications in severe cases. It supports, but does not replace, heart imaging. PMC

22. Electroencephalogram (EEG). Used when seizures or altered consciousness suggest brain involvement in neurobrucellosis. PMC

23. Nerve conduction studies. If there is numbness or weakness, these tests check for peripheral neuropathy from inflammatory nerve involvement. PMC

24. Electromyography (EMG). Measures muscle electrical activity to support radiculopathy or myositis linked to focal brucella infection. PMC

E) Imaging tests (pictures of organs and bones)

25. Ultrasound of abdomen. Checks liver and spleen size, looks for abscesses, and guides drainage if needed. It is quick and has no radiation. PMC

26. Echocardiography (heart ultrasound). Essential if endocarditis is suspected; it can show valve infection or leaks. This complication drives most brucellosis deaths. NCBI

27. MRI of spine or sacroiliac joints. Best test for early bone, disc, and joint involvement; it shows inflammation before X-rays do. PMC

28. MRI or CT of brain. Used when there are neurologic symptoms to look for meningitis, abscess, or cranial nerve involvement. PMC

29. CT scan of chest/abdomen/pelvis. Defines abscesses or organ involvement and helps surgeons plan drainage when needed. PMC

30. Plain X-rays (spine or joints). May show late bone changes from chronic infection, but early disease can look normal, so MRI is often preferred. Wikipedia

31. Nuclear bone scan or PET-CT (selected cases). Helps find hidden foci when symptoms are vague and standard imaging is inconclusive. PMC

Non-pharmacological treatments (therapies & other care)

1. Pasteurized-only diet and strict food hygiene
   What: Switch to pasteurized milk and cheeses; cook meat to safe temperatures; avoid raw milk products entirely. Why: Raw dairy is a major source of Brucella. How it helps: Pasteurization heats milk to kill Brucella and other dangerous germs; safe cooking reduces the chance any bacteria survive.

2. Early diagnosis + full treatment course adherence
   What: Start antibiotics quickly after diagnosis and take them exactly as prescribed for the full duration. Why: Short or interrupted therapy raises relapse risk. How it helps: Long enough combination therapy clears bacteria hiding inside cells.

3. Occupational protective measures (PPE)
   What: Farmers, veterinarians, abattoir workers, and lab staff use gloves, masks, eye protection, and safe handling of animal tissues and cultures. Why: Direct contact and aerosols can transmit Brucella. How it helps: Barriers reduce exposure to infectious fluids and tissues.

4. Patient education & relapse watch
   What: Teach warning signs (recurrent fever, sweats, back pain, chest pain) and the need to return if symptoms come back. Why: Relapse can occur even after good therapy. How it helps: Fast evaluation prevents progression to serious complications.

5. Hydration, rest, and graded activity
   What: Hydrate well, rest during fevers, and slowly increase activity as fatigue improves. Why: Fevers and sweats dehydrate; fatigue is common. How it helps: Supports circulation and recovery while avoiding overexertion that can worsen symptoms.

6. Fever control and symptom support
   What: Cool compresses, tepid sponging, and clinician-advised antipyretic strategies; monitor for persistent high fevers. Why: Comfort and safety. How it helps: Reduces metabolic stress while antibiotics work.

7. Bone/joint care & physical therapy
   What: For spondylitis or arthritis, use spine precautions, targeted physiotherapy, and bracing when indicated. Why: Brucellosis often targets the spine and joints. How it helps: Protects the spine, maintains mobility, and speeds return to function alongside antibiotics.

8. Abscess management strategy
   What: If imaging shows liver or other deep abscesses that don’t improve, consider interventional drainage in addition to medicines. Why: Some abscesses persist despite drugs. How it helps: Draining pus lowers bacterial load; reduces relapse risk.

9. Cardiac complication pathway
   What: Rapid referral if endocarditis is suspected (new heart murmur, heart failure symptoms). Why: Brucella endocarditis is the top cause of brucellosis-related deaths; often needs surgery plus antibiotics. How it helps: Early combined medical-surgical care improves survival.

10. Neurologic complication monitoring
    What: Watch for severe headaches, neck stiffness, mood/cognitive changes. Why: Neurobrucellosis requires longer, CNS-penetrating regimens (often with ceftriaxone). How it helps: Tailored therapy prevents long-term deficits.

11. Public health reporting & source control
    What: Notify public health authorities; trace foods/exposures; advise family/coworkers at risk. Why: Prevents more cases from the same source. How it helps: Enables investigation, animal control measures, and consumer advisories.

12. Avoid blood and tissue donation until cleared
    What: Defer donations during illness and for a clinician-advised period after cure. Why: Minimizes theoretical transmission risk. How it helps: Protects recipients.

Core drug treatments

Brucellosis therapy almost always uses combinations for 6–8+ weeks to prevent relapse. Regimens for special sites (endocarditis, spondylitis, neurobrucellosis) can be longer and may add an aminoglycoside for the first 1–2 weeks. Always individualize to age, pregnancy status, allergies, and comorbidities.

1. Doxycycline
   Class: Tetracycline antibiotic. Typical adult dose/time: 100 mg orally every 12 hours, usually for ≥6 weeks, almost always in combination (e.g., with rifampin; sometimes with an aminoglycoside initially). Purpose: Backbone drug for brucellosis. Mechanism: Blocks bacterial protein synthesis; penetrates cells where Brucella lives. Side effects (key): Photosensitivity, esophagitis, GI upset; avoid in pregnancy and young children when alternatives exist; interactions with antacids/iron. Evidence/label: FDA labeling explicitly lists brucellosis (with streptomycin) as an indication; CDC recommends doxycycline-based combinations for 6–8 weeks.

2. Rifampin (rifampicin)
   Class: Rifamycin. Typical dose/time: 600 mg orally once daily for ≥6 weeks in combination (commonly with doxycycline). Purpose: Reduces relapse when paired with doxycycline. Mechanism: Inhibits bacterial RNA polymerase; intracellular activity. Side effects (key): Orange discoloration of fluids, hepatotoxicity, drug interactions via enzyme induction (many!). Evidence/label: FDA label details indications and strong enzyme-inducing interactions; its use in brucellosis is guideline-based (off-label in the U.S.) and standard in combinations.

3. Streptomycin (initial 1–2 weeks)
   Class: Aminoglycoside (injectable). Typical dose/time: 1 g IM daily for 14 days plus doxycycline for ≥6 weeks. Purpose: For severe disease or to reduce relapse risk. Mechanism: Rapid bactericidal action on protein synthesis; synergizes with doxycycline. Side effects: Ototoxicity, nephrotoxicity (monitor levels/renal function). Evidence/label: FDA label lists Brucella among non-TB infections; widely used in combination regimens.

4. Gentamicin (alternative to streptomycin, initial 1–2 weeks)
   Class: Aminoglycoside (IV/IM). Typical dose/time: 5 mg/kg/day IV/IM divided or once-daily for 7–14 days plus doxycycline-based regimen. Purpose: Substitute where streptomycin unavailable. Mechanism: Bactericidal; good early kill. Side effects: Nephro/ototoxicity—monitor. Evidence/label: FDA label describes indications for serious susceptible infections; CDC allows gentamicin in place of streptomycin in combination therapy.

5. Trimethoprim-Sulfamethoxazole (TMP-SMX)
   Class: Antifolate combination. Typical dose/time: 160/800 mg (DS) orally every 12 hours for ≥6 weeks combined with rifampin or an aminoglycoside, especially for children <8 years or pregnancy (when tetracyclines are contraindicated) per specialist advice. Purpose: Alternative backbone when doxycycline cannot be used. Mechanism: Blocks folate metabolism; intracellular activity. Side effects: Rash, hyperkalemia, rare severe reactions. Evidence/label: FDA label supports broad bacterial coverage; WHO notes TMP-SMX combinations as options in children.

6. Ceftriaxone (for neurobrucellosis or severe focal disease)
   Class: Third-generation cephalosporin (IV). Typical dose/time: 2 g IV daily (or q12 h) for several weeks with doxycycline/rifampin, tailored by specialists. Purpose: Better CNS penetration. Mechanism: Inhibits cell wall synthesis. Side effects: Biliary sludging, diarrhea, rare allergy. Evidence: Frequently included in expert regimens for neurobrucellosis; see specialty reviews.

7. Ciprofloxacin / Ofloxacin / Levofloxacin (fluoroquinolones)
   Class: Fluoroquinolones. Typical dose/time: e.g., ciprofloxacin 500–750 mg twice daily with rifampin for ≥6 weeks if tetracyclines not suitable; regimens vary. Purpose: Alternative combos; not first line when doxycycline is possible. Mechanism: Inhibits DNA gyrase/topoisomerase. Side effects: Tendinopathy, neuropathy, QT effects; avoid in pregnancy. Evidence: Used as alternatives or add-ons in complicated disease per clinical reviews.

8. Amikacin (aminoglycoside alternative)
   Class: Aminoglycoside (IV/IM). Typical dose/time: 15 mg/kg/day for 7–14 days with doxycycline-rifampin. Purpose: Severe disease when streptomycin unavailable. Mechanism/risks: Like gentamicin; monitor kidneys/hearing. Evidence: Used in difficult or resistant cases in expert practice.

9. Minocycline (alternative tetracycline)
   Class: Tetracycline. Typical use: Substitute for doxycycline when necessary, with rifampin; dosing individualized. Note: Less data than doxycycline; similar class cautions (pregnancy/children, photosensitivity). Evidence: Considered when intolerance to doxycycline occurs.

10. Azithromycin (selected situations)
    Class: Macrolide. Use: Occasionally combined when others cannot be used; not a preferred backbone. Mechanism: Protein synthesis inhibitor. Evidence: Limited; specialist-driven scenarios only.

11. Cefotaxime (IV cephalosporin alternative)
    Use: Similar to ceftriaxone in CNS or severe focal infection as part of combination therapy, per specialist guidance. Evidence: Case-based use.

12. Tigecycline (rescue use only)
    Class: Glycylcycline (IV). Use: Salvage for highly complicated or resistant cases with close monitoring; always in combination. Note: Nausea common; mortality signal in some indications—specialist decision only.

Important FDA-label safety notes for doxycycline (example): avoid excess sun, drink plenty of water with capsules, beware interactions (antacids containing aluminum/calcium/magnesium and iron can reduce absorption), and use caution in pregnancy and in children ≤8 unless benefits outweigh risks. Similar class- and drug-specific cautions apply to others listed above.

Immune-booster / regenerative / stem-cell” drugs

There are no FDA-approved “immune-boosting” or stem-cell drugs for treating brucellosis, and unregulated immune therapies can be harmful. Treatment is antibiotics plus procedures for complications. Supportive care (nutrition, vaccines per routine schedule, probiotics to reduce antibiotic-associated diarrhea risk) may help comfort and adherence, but they do not replace antibiotics. If you see offers for stem-cell “cures,” treat them as unsafe.

If a patient develops low white cells or other complications from another cause, hematology may use agents like filgrastim—but not to treat brucellosis itself. Any such use requires specialist oversight. (I’m purposely not listing “six drugs” here to avoid implying they’re recommended—because they aren’t.)

---

Dietary molecular supplements

Always review supplements with a clinician to avoid drug interactions (e.g., rifampin induces metabolism; doxycycline absorption drops with iron/calcium).

1. Probiotics (e.g., Lactobacillus spp., Saccharomyces boulardii)
   Dose: Commonly 10–20 billion CFU/day; S. boulardii often 250–500 mg 1–2×/day during antibiotics. Function/mechanism: Helps maintain gut microbiome, may reduce antibiotic-associated diarrhea and C. difficile risk; yeast species are not killed by antibiotics. Note: Avoid in severely immunocompromised.

2. Vitamin D
   Dose: Typically 600–2,000 IU/day depending on baseline levels; test-guided. Function/mechanism: Supports innate and adaptive immunity; promotes antimicrobial peptides (cathelicidin). Caution: Excess can cause hypercalcemia—stay within evidence-based limits.

3. Zinc
   Dose: Often 8–11 mg/day (dietary reference); short-term supplementation sometimes 15–30 mg/day with clinician oversight. Function/mechanism: Cofactor for immune enzymes; supports epithelial barriers; antiviral/anti-inflammatory roles shown in other infections. Caution: Too much zinc can lower copper.

4. Lactoferrin
   Dose: Common supplements 100–300 mg/day in studies. Function/mechanism: Iron-binding protein with antimicrobial and immunomodulatory effects; generally well tolerated. Note: Evidence is growing but mixed across pathogens.

5. Quercetin
   Dose: Frequently 500–1,000 mg/day short-term in studies. Function/mechanism: Plant flavonoid with anti-inflammatory/antioxidant activity; modulates immune cell signaling. Caution: Drug interactions possible (CYP enzymes).

6. Omega-3 fatty acids (EPA/DHA)
   Dose: 1–2 g/day combined EPA/DHA. Function/mechanism: Anti-inflammatory lipid mediators; may help joint discomfort while antibiotics work. Note: Bleeding risk at high doses. (General evidence basis.)

7. N-Acetylcysteine (NAC)
   Dose: 600–1,200 mg/day. Function/mechanism: Antioxidant and mucolytic; may support oxidative balance during long antibiotic courses. (General mechanism evidence.)

8. Curcumin (with piperine for absorption)
   Dose: 500–1,000 mg/day standardized extract. Function/mechanism: Anti-inflammatory signaling modulation. Caution: Interacts with anticoagulants; variable bioavailability. (General mechanism evidence.)

Supplements are adjuncts only; they do not treat brucellosis. Always prioritize prescribed antibiotics.

Surgeries

1. Valve replacement for Brucella endocarditis
   Procedure: Replace destroyed heart valve(s), typically the aortic valve, plus prolonged combination antibiotics. Why: Medical therapy alone carries high mortality; surgery markedly improves survival in many series.

2. Spinal debridement/decompression ± fusion for brucellar spondylitis
   Procedure: Remove infected tissue, decompress neural elements, stabilize the spine, sometimes with posterior pedicle fixation and interbody fusion. Why: Persistent pain, instability, or neurologic compromise despite antibiotics.

3. Percutaneous drainage of hepatic (or splenic) brucelloma
   Procedure: Image-guided catheter drainage with concurrent antibiotics; surgery if drainage fails. Why: Deep abscess not resolving on medicines alone.

4. Surgical drainage of epidural or paraspinal abscess
   Procedure: Endoscopic or open drainage/debridement. Why: Spinal cord compression or persistent sepsis.

5. Other focused procedures (case-by-case)
   Examples: Debridement of osteoarticular foci; rare orchiectomy for refractory epididymo-orchitis; resection of calcified hepatic brucelloma if recalcitrant. Why: Remove persistent infectious nidus to prevent relapse.

Prevention tips

1. Choose pasteurized milk and cheeses only.

2. Cook all meat thoroughly; avoid undercooked liver and offal.

3. Wear PPE when handling animals, birth products, or carcasses.

4. Cover cuts; wash hands after animal contact.

5. Follow lab biosafety protocols for Brucella.

6. Control animal infection (veterinary vaccination, testing, culling where indicated).

7. Avoid unregulated raw-milk soft cheeses when traveling.

8. Report suspected cases to public health to find sources fast.

9. Educate high-risk workers and communities.

10. Finish all prescribed antibiotics to reduce relapse.

---

When to see a doctor

• Now/urgent: Persistent or high fevers with sweats after animal or raw-dairy exposure; chest pain, new heart murmur, shortness of breath (possible endocarditis); severe back pain with weakness/numbness (possible spinal infection); severe headache/neck stiffness or confusion (possible neurobrucellosis).

• Soon (within days): Recurrent fevers after prior brucellosis, unintentional weight loss, ongoing joint pain/swelling, or if you cannot tolerate your medicines.

---

What to eat & what to avoid

Eat:

• Balanced meals with lean proteins, fruits, vegetables, whole grains, and plenty of fluids to replace sweat losses and support healing. Why: Supports energy and tissue repair.

Avoid / be careful with:

• Raw milk and soft cheeses from raw milk (always).

• Antacids/iron/calcium near doxycycline doses (can reduce absorption); separate by several hours per clinician advice.

• Alcohol (rifampin and doxycycline can affect the liver; alcohol adds risk).

FAQs

1. Is Maltese fever contagious between people?
   Human-to-human spread is rare. Most infections come from animals or raw dairy.

2. How long does treatment last?
   Usually 6–8 weeks; longer for complicated disease.

3. Why do doctors use two or more antibiotics?
   Combinations lower relapse by targeting bacteria inside cells and across different metabolic pathways.

4. Can I get brucellosis from pasteurized milk?
   Pasteurization kills Brucella, so properly pasteurized milk is safe.

5. What if I’m pregnant or my child is under 8?
   Tetracyclines (like doxycycline) are usually avoided. Specialists use alternative combinations such as TMP-SMX with an aminoglycoside or rifampin depending on the case.

6. Do probiotics help while I’m on antibiotics?
   They can lower the risk of antibiotic-associated diarrhea; ask your clinician which product and dose fit you.

7. Will I be immune after recovery?
   Immunity is not complete; reinfection can occur if you’re exposed again. Prevention still matters.

8. What side effects should I watch for on doxycycline?
   Sun sensitivity, stomach upset, and esophageal irritation; avoid antacids/iron near the dose. Drink water with capsules.

9. Why is raw milk risky?
   It can carry live Brucella and many other germs; pasteurization removes this risk.

10. If my fevers return after finishing medicines, what should I do?
    See your doctor promptly—relapse can happen and is treatable.

11. Can brucellosis affect the heart or spine?
    Yes. Endocarditis and spondylitis are serious complications; some cases need surgery plus long antibiotics.

12. Are there approved stem-cell or “immune booster” drugs for brucellosis?
    No—avoid such claims. Effective care is antibiotics, procedures when needed, and prevention.
