Piroplasmosis, also called babesiosis, is an infection caused by tiny parasites that live inside red blood cells. These parasites are usually from the Babesia group. When they invade red blood cells, the cells break down (hemolysis). This can cause fever, chills, tiredness, low blood count (anemia), and yellow skin or eyes (jaundice). People most often get the parasites from the bite of an infected blacklegged tick (deer tick). Rarely, the infection spreads through blood transfusion, from mother to baby during pregnancy, or after an organ transplant. In many people the illness is mild or has no symptoms. In older adults, people without a spleen, or people with weak immune systems, the disease can be severe. CDC+2CDC+2
Piroplasmosis, better known in human medicine as babesiosis, is a parasitic infection of red blood cells caused mainly by Babesia species transmitted by blacklegged ticks (often the same ticks that spread Lyme). The parasite lives inside red blood cells, so illness can look like malaria: fever, chills, fatigue, anemia, and jaundice. Most healthy people have mild disease, but severe illness can occur in people who are older, immunocompromised, or without a spleen. Treatment is with specific antimicrobial combinations, and severe cases may need red-blood-cell exchange transfusion. Prevention centers on tick-bite avoidance and rapid tick removal. CDC+2CDC+2
Other names
Babesiosis (the most common human name)
Piroplasmosis (older or broader term; also used in animals)
Texas cattle fever / redwater (animal terms you may see in older texts; included here because “piroplasmosis” is often used for animals too) Wikipedia
Types
Babesia microti (North America, especially Northeast and Upper Midwest)
The most common cause in people in the United States. It spreads by Ixodes scapularis (deer tick). Illness ranges from silent to severe. Coinfection with Lyme disease can occur because the same tick carries both. CDCBabesia duncani (Pacific Northwest, USA)
Less common. Can cause moderate to severe disease, including in healthy people. CDCBabesia divergens (Europe; severe in asplenic patients)
Classically severe in people who have no spleen. It can cause fast-moving hemolysis. CDCMO-1–like / other Babesia strains
Occasional human cases are caused by other strains. They are identified by specialized lab tests (PCR and gene sequencing). CDC+1Transfusion-transmitted babesiosis
This type happens when blood from an infected donor is given to someone. Donors may have no symptoms. Screening is improving but risk still exists. CDCCongenital babesiosis
A pregnant person with infection can rarely pass it to the baby. Newborns may have fever, anemia, and jaundice. CDC
Causes
Note: The “cause” is infection by Babesia parasites. Below are the exposure routes and conditions that lead to or enable infection.
Bite from an infected blacklegged (deer) tick
This is the main cause. The tick feeds on you long enough to pass the parasite into your blood. CDCOutdoor activity in tick habitats
Walking, camping, or working in grassy, brushy, or wooded areas increases tick contact and infection risk. CDCNot using tick protection
No repellent, no protective clothing, or no tick checks after outdoor time raises the chance a feeding tick goes unnoticed. CDCHaving deer, mice, or tick hosts near home
Living where animal hosts and ticks thrive increases exposure. CDCBlood transfusion from an infected donor
Parasites travel in donor red cells. Infection may occur days to weeks after transfusion. CDCOrgan transplantation from an infected donor
Very rare, but infection can be transmitted with an organ. CDCInfection during pregnancy (congenital)
Parasites can cross the placenta, leading to infection in the newborn. CDCNo spleen (asplenia)
The spleen helps clear infected red cells. Without it, parasites grow faster and cause severe disease. This does not “cause” exposure, but it strongly promotes infection once exposed. CDCWeakened immune system
Cancer therapy, steroids, HIV, or other immune problems make infection more likely and more severe after exposure. CDCOlder age
Older adults have higher risk of severe illness after exposure. CDCCoinfection with other tick-borne diseases
The same tick can carry Lyme disease and anaplasmosis. Coinfection can worsen symptoms and complicate diagnosis. New England Journal of MedicineLonger tick attachment time
The longer the tick feeds, the more likely transmission occurs. Prompt removal reduces risk. CDCLate spring and summer seasons
Ticks are more active in warm months, increasing exposure. CDCLiving in or traveling to endemic regions
U.S. Northeast/Upper Midwest, parts of the Pacific Northwest, and some European regions have more cases. CDCYard or field work without protection
Mowing fields, landscaping, or farming near brush increases tick exposure. CDCPets that carry ticks indoors
Pets can bring ticks into homes, raising risk for people. CDCNot checking the whole body after being outdoors
Ticks can be tiny. Missing one allows longer feeding and transmission. CDCNot showering soon after outdoor exposure
Showering within two hours can help wash off unattached ticks. Skipping this step can increase risk. CDCSleeping in tick-infested cabins or camps
Exposure can occur at night if ticks are present in bedding or clothing. CDCHandling wildlife without protection
Contact with tick-infested wildlife or carcasses can bring ticks onto the body. CDC
Symptoms
Symptoms often start 1–4 weeks after a tick bite. Some people have no symptoms. Others become very sick, especially if they lack a spleen or have weak immunity. ndc.services.cdc.gov+1
Fever – often the first sign; may be high and come in waves. The parasite triggers the immune system and causes temperature spikes. CDC
Chills and sweats – classic “flu-like” attacks linked to red cell rupture cycles. CDC
Severe tiredness (fatigue) – anemia and inflammation drain energy. CDC
Headache – common with many tick-borne infections and fevers. CDC
Muscle aches and joint pains – whole-body soreness from inflammation. CDC
Loss of appetite and nausea – illness stress and mild liver irritation reduce appetite. ndc.services.cdc.gov
Vomiting – may happen with more severe disease or in children. ndc.services.cdc.gov
Dark urine – from hemolysis; broken red cells release pigment that darkens urine. ndc.services.cdc.gov
Yellow skin or eyes (jaundice) – buildup of bilirubin from destroyed red cells. ndc.services.cdc.gov
Pale skin – anemia makes the skin look pale. CDC
Shortness of breath – anemia reduces oxygen delivery; severe cases can involve lung problems. CDC
Chest discomfort or fast heartbeat – the heart works harder during fever and anemia. (Doctors use ECG to monitor if needed.) CDC
Confusion or trouble thinking – can occur in severe illness with low oxygen, low blood pressure, or high fever. CDC
Abdominal or left-shoulder pain – may reflect spleen swelling or, rarely, infarct or rupture. SpringerLink
Worsening of other illnesses – babesiosis can stress the body and worsen heart, lung, or liver conditions. CDC
Diagnostic tests
No single test fits every case. Doctors use history, exam, and a set of tests to confirm infection and track severity. The gold standard is finding parasites on a blood smear, often supported by PCR and antibody tests. CDC+1
A) Physical examination (what the clinician looks for)
Fever check (temperature)
A thermometer confirms fever. Fevers that spike and return suggest a blood-parasite illness like babesiosis. CDCPulse and blood pressure
Fast heart rate and low blood pressure can signal severe infection or dehydration. This helps decide if hospital care is needed. CDCSkin and eye exam for pallor and jaundice
Pale skin suggests anemia; yellow eyes or skin suggest bilirubin buildup from red-cell destruction. ndc.services.cdc.govSpleen and liver exam (palpation)
Tenderness or enlargement may appear because these organs filter damaged red cells. Pain to the left upper abdomen can suggest spleen problems. SpringerLinkLung exam
Listening for crackles or fast breathing can reveal lung stress or, in severe cases, early lung injury that needs quick care. CDC
B) “Manual” bedside tests and observations
Orthostatic vital signs
Measuring heart rate and blood pressure lying and standing helps detect dehydration or low blood volume from fever and poor intake.Capillary refill and perfusion check
A simple finger-press test helps judge circulation when anemia is severe.Pulse oximetry
A fingertip sensor checks oxygen levels, which can drop with anemia or lung complications. This is not a parasite test, but it guides urgent care.Pain localization maneuvers
Gentle pressure over the left upper abdomen can reveal spleen tenderness that supports the diagnosis context (with labs).Tick-exposure review and full skin search
Careful questioning and a head-to-toe tick check improve diagnostic accuracy when labs are pending. CDC
C) Laboratory and pathological tests
Peripheral blood smear (Giemsa-stained thin smear)
This is the key test. A lab specialist looks at red blood cells under a microscope. Seeing ring-shaped parasites or the classic “Maltese cross” tetrads confirms babesiosis. Multiple smears over 24–48 hours may be needed when parasite levels are low. CDC+1PCR for Babesia DNA
PCR detects parasite genetic material and is very useful when smears are negative or parasite levels are low. It can also identify the species (B. microti, B. divergens, B. duncani). CDCSerology (indirect fluorescent antibody, IFA)
Antibody tests help support diagnosis, especially in later illness or when smears/PCR are inconclusive. Rising titers over time strengthen the diagnosis. (Serology alone does not prove active infection.) CDCComplete blood count (CBC)
Low hemoglobin (anemia) and low platelets (thrombocytopenia) are common. White blood cell count may be normal or low. This helps measure severity. ndc.services.cdc.govHemolysis panel (LDH, haptoglobin, bilirubin, reticulocyte count)
High LDH and bilirubin with low haptoglobin show red-cell destruction. Reticulocytes rise as the bone marrow tries to replace lost cells. ndc.services.cdc.govLiver function tests (AST, ALT, alkaline phosphatase)
These may be elevated because the liver processes breakdown products from hemolysis. The results help grade severity. ndc.services.cdc.govKidney function tests (creatinine, BUN, urinalysis)
Kidney strain may occur in severe disease or dehydration. Dark urine and protein or blood on urinalysis can appear with hemolysis. CDCBlood parasite percent (parasitemia quantification)
Counting the percentage of infected red cells on smear guides urgency. Higher parasitemia means higher risk of complications and may trigger intensive therapy decisions. CDCTests for coinfections (Lyme, anaplasmosis)
Because the same tick can carry several pathogens, testing for Lyme disease (Borrelia burgdorferi) and anaplasmosis is often appropriate, especially with severe or atypical illness. New England Journal of MedicineBlood culture (rule-out of bacterial sepsis)
Babesia does not grow in standard blood cultures, but cultures help exclude bacterial causes of fever while parasite tests are pending. (Negative cultures with positive smear/PCR favor babesiosis.) CDC
D) Electrodiagnostic tests (supportive, not parasite-specific)
Electrocardiogram (ECG)
Used if there is chest pain, fast heartbeat, or concern about heart strain from fever and anemia. It does not diagnose Babesia. It helps guide safe care. CDCContinuous cardiac/oxygen monitoring in hospital
Monitors are used for very ill patients to watch for low oxygen, arrhythmias, or shock. Again, this is supportive. CDC
E) Imaging tests (to assess complications)
Abdominal ultrasound or CT scan
These can show an enlarged spleen or, rarely, a splenic infarct or bleeding in severe disease. Pain in the left upper abdomen may prompt this imaging. SpringerLinkChest X-ray
Used when there is cough, shortness of breath, or low oxygen. It looks for lung problems that can occur in severe illness. CDCHead CT/MRI
Considered if there is confusion, severe headache, or neurologic symptoms, to look for other causes and complications. CDC
Non-pharmacological treatments (therapies & other measures)

Drug treatments
Only a handful of drugs are evidence-based for babesiosis. Authoritative guidelines recommend atovaquone + azithromycin as first-line for most, and clindamycin + quinine as the main alternative—typically for 7–10 days; longer courses for immunocompromised patients. Severe disease may need exchange transfusion in addition to meds. Dosages vary, so clinicians use weight, severity, and comorbidities to tailor therapy. IDSA+1
The specific FDA labels below are provided for evidence and safety information about each drug. (They are not labeled for babesiosis per se; clinicians use them based on expert guidelines.)
1) Atovaquone (brand: MEPRON®)
Description (≈150 words). Atovaquone is a hydroxynaphthoquinone that inhibits parasite mitochondrial electron transport (cytochrome bc1 complex), collapsing energy production in protozoa. In babesiosis, atovaquone is combined with azithromycin and is generally well tolerated; GI upset and rash can occur. It must be taken with food to enhance absorption (a key practical point). It’s available as an oral suspension (750 mg/5 mL). Although the FDA label focuses on Pneumocystis jirovecii pneumonia, the pharmacology and safety profile are leveraged off-label in babesiosis based on IDSA and CDC guidance. Clinicians monitor for treatment failure or relapse, particularly in asplenic or immunocompromised patients, and may extend duration accordingly. FDA Access Data+2FDA Access Data+2
Drug class: Antiprotozoal (hydroxynaphthoquinone). Typical adult dose (guideline): 750 mg orally twice daily with food, plus azithromycin, usually 7–10 days (longer if immunocompromised). Timing/purpose: Start as soon as babesiosis is diagnosed or strongly suspected. Mechanism: Blocks parasite mitochondrial respiration. Key adverse effects: GI upset, rash; take with food for adequate levels. CDC+2IDSA+2
2) Azithromycin (ZITHROMAX®)
Description (≈150 words). Azithromycin is a macrolide that binds the 50S ribosomal subunit, inhibiting protein synthesis. In babesiosis it’s paired with atovaquone; this combination is preferred for most mild-to-moderate cases because it’s effective and better tolerated than quinine-based therapy. The first dose is often higher (loading dose) followed by daily dosing. Common side effects include GI upset; rare risks include QT prolongation and hepatic effects, so clinicians review other QT-prolonging drugs and liver status. The FDA label details broad antibacterial uses; in babesiosis, use is based on IDSA/CDC guidance. FDA Access Data+2FDA Access Data+2
Drug class: Macrolide antibacterial. Typical adult dose (guideline): 500 mg orally on day 1, then 250 mg daily (with atovaquone) for 7–10 days (longer in special hosts). Mechanism: Inhibits parasite protein synthesis (indirect effect leveraged in combination). Key adverse effects: GI upset, rare QT prolongation, hepatotoxicity. CDC
3) Clindamycin (CLEOCIN®)
Description (≈150 words). Clindamycin binds the 50S ribosomal subunit, inhibiting protein synthesis. In babesiosis, clindamycin is combined with quinine as the historical alternative regimen, used especially for severe disease or when atovaquone/azithromycin is unsuitable. IV clindamycin can be used in hospitalized, very ill patients. Tolerability is generally good, but it carries a known risk of C. difficile colitis; labels emphasize stopping unnecessary antibiotics and supporting fluids/electrolytes if it occurs. For babesiosis, regimen duration is individualized; parasitemia is monitored closely in severe cases. FDA Access Data+2FDA Access Data+2
Drug class: Lincosamide antibacterial. Typical adult dose (guideline): 600 mg three times daily orally (or IV 300–600 mg q6–8h), plus quinine, 7–10 days (longer if indicated). Mechanism: Inhibits protein synthesis. Key adverse effects: Diarrhea, including C. difficile; rash; elevated LFTs. CDC
4) Quinine (QUALAQUIN®)
Description (≈150 words). Quinine is a cinchona alkaloid antimalarial that interferes with parasite heme detoxification, leading to toxic heme accumulation. In babesiosis it’s used with clindamycin as an alternative regimen, especially for severe disease. Quinine has a boxed warning for serious hematologic reactions and is not approved for nocturnal leg cramps; dosing is tailored and monitored closely. Adverse effects include cinchonism (tinnitus, headache), hypoglycemia, QT prolongation, and rare severe thrombocytopenia/HUS/TTP. Its modern use in babesiosis is guided by IDSA/CDC rather than on-label indications. Careful ECG/electrolyte monitoring is prudent in the hospital setting. FDA Access Data+1
Drug class: Antimalarial alkaloid. Typical adult dose (guideline): 650 mg three times daily orally, plus clindamycin, generally 7–10 days (adjust per tolerance/severity). Mechanism: Interferes with parasite heme handling. Key adverse effects: Cinchonism, hypoglycemia, QT prolongation, rare severe hematologic reactions. CDC
Why only four drugs? Current high-quality guidance supports these combinations. Other antibacterials (e.g., doxycycline) are used for tick-borne co-infections (Lyme, anaplasmosis) but do not treat babesiosis itself. Off-label agents (e.g., tafenoquine) have limited case-based data; they’re not standard of care. Always anchor therapy to CDC/IDSA recommendations. IDSA+1
Dietary molecular supplements
There are no supplements proven to treat babesiosis. If patients use supplements, they should be adjuncts for general health, with clinician oversight—especially during hepatic stress or polypharmacy. The themes below focus on anemia/hemolysis support, energy, and recovery. (Always avoid interactions with quinine/macrolides and stop if liver tests worsen.)
Oral hydration solutions (electrolytes, glucose) may help during fever to maintain volume and kidney perfusion; they do not treat the parasite. Medscape
Balanced multivitamin for short-term convalescence (avoid megadoses). Medscape
Folate-rich diet or standard folate supports erythropoiesis during hemolysis recovery; only use standard doses. Medscape
Vitamin B12 if deficient; helps red-cell production (test-guided). Medscape
Vitamin C from foods may aid iron absorption and general antioxidant balance; avoid high-dose supplements that upset stomach. Medscape
Protein-adequate meals to support marrow recovery; small frequent meals if nauseated. Medscape
Iron only if lab-confirmed deficiency (hemolysis itself is not iron deficiency); giving iron without deficiency can be harmful. Medscape
Probiotics/fermented foods may help antibiotic-associated GI symptoms for some; avoid if severely immunocompromised unless approved by clinician. Medscape
Omega-3-rich foods (fish, flax) to support general cardiometabolic health during recovery. Medscape
Caffeine-free herbal teas (e.g., ginger) for nausea comfort—not an antiparasitic. Medscape
Immunity booster / regenerative / stem-cell drugs
There are no approved immunity-boosting drugs, regenerative medicines, or stem-cell therapies for babesiosis. Using such treatments would be experimental and potentially risky outside of trials. The safe, evidence-based approach is the antimicrobial combinations above, with exchange transfusion for selected severe cases, plus rigorous prevention. If immune status is compromised (e.g., after splenectomy or chemotherapy), clinicians may individualize longer antimicrobial courses and close monitoring rather than unproven “immune boosters.” IDSA+1
Procedures
Red-blood-cell exchange transfusion (erythrocytapheresis): rapidly lowers parasitemia and removes hemolyzing cells in severe disease (e.g., high parasitemia, organ failure). Why: improve oxygen delivery and reduce complications while drugs work. Medscape+1
Central venous catheter placement: enables apheresis/ICU infusions safely. Why: procedural access for exchange transfusion/pressors. Medscape
Packed red-cell transfusion (non-exchange): for symptomatic severe anemia. Why: restore oxygen-carrying capacity. Medscape
Hemodialysis (with temporary dialysis catheter): for acute kidney injury from severe hemolysis. Why: manage uremia/volume while recovering. Medscape
Endotracheal intubation/mechanical ventilation: if ARDS/respiratory failure occurs. Why: life support during critical illness. Medscape
Notably, there are no “curative surgeries” for babesiosis; the main interventional therapy is exchange transfusion in selected severe cases. Medscape
Preventions
Avoid brush/leaf litter where ticks live; stick to center of trails.
Wear long sleeves/pants; tuck pants into socks.
Treat clothing/shoes with permethrin.
Use EPA-registered repellents (DEET, picaridin, oil of lemon eucalyptus) on skin.
Do full-body tick checks after outdoor time; shower soon after.
Prompt tick removal with fine-tipped tweezers.
Protect pets and check them daily.
Maintain yards: clear brush, create gravel/mulch borders.
Know local tick seasons and hotspots.
After blood transfusion, report fevers promptly (rare transfusion transmission). CDC+2CDC+2
When to see a doctor
Seek medical care immediately if you live in or visited an endemic area and develop fever, chills, sweats, dark urine, jaundice, severe fatigue, shortness of breath, confusion, or chest pain—especially if you are older, have a weak immune system, or do not have a spleen. Anyone with a tick bite who becomes febrile within days to weeks should be assessed; babesiosis can mimic flu or malaria, and early treatment shortens illness and lowers complications. If you’re already diagnosed/treated, return urgently for worsening symptoms, fainting, yellowing eyes/skin, or breathing trouble. CDC
What to eat and what to avoid
Eat: (1) Small frequent meals if nauseated; (2) Hydrating fluids/electrolytes; (3) Protein-rich foods for recovery; (4) Iron-rich foods only if you’re iron-deficient; (5) Folate- and B12-containing foods. Avoid: (6) Alcohol (liver stress); (7) High-dose supplements without clinician input; (8) Dehydrating caffeinated/energy drinks when ill; (9) Raw or risky foods if severely immunocompromised; (10) Herbal products that interact with QT or CYP pathways (important if on quinine/azithromycin). These measures do not treat babesiosis; they support comfort and safety during recovery. Medscape
FAQs
1) Is babesiosis contagious person-to-person?
No. It spreads via ticks or rarely blood transfusion and very rarely mother-to-baby. CDC
2) How soon after a tick bite can symptoms appear?
Within a week to several weeks (sometimes months). Many infections are mild or silent. CDC
3) Do I always need treatment?
Symptomatic cases usually need antimicrobials. Asymptomatic, low-level parasitemia may be watched in select hosts, but decisions are individualized. IDSA
4) What’s the first-line treatment?
Atovaquone + azithromycin for most; clindamycin + quinine is the alternative, especially for severe disease. IDSA
5) How long is treatment?
Typically 7–10 days; longer courses are used for immunocompromised or asplenic patients. CDC
6) What if I get very sick?
Hospital care plus the same drugs; some patients need exchange transfusion to rapidly lower parasite load. Medscape
7) Is there a vaccine?
No human vaccine. Prevention relies on tick-bite avoidance. CDC
8) Should I take antibiotics after any tick bite to prevent babesiosis?
No. Post-exposure antibiotics are not used to prevent babesiosis (unlike some Lyme protocols). Watch for symptoms and seek care if they develop. CDC
9) Can babesiosis come back?
Relapses can occur, especially in immunocompromised or asplenic patients; clinicians may extend therapy and monitor smears/PCR. IDSA
10) What about herbal/“immune booster” products?
No proven benefit; some interact with quinine or macrolides. Discuss any products with your clinician. FDA Access Data+1
11) Should my family be tested?
Household members aren’t exposed from you, but they share the same tick environment; focus on prevention and test only if symptomatic. CDC
12) How do doctors confirm babesiosis?
Blood smear, PCR, and labs for hemolysis; they may repeat smears to track parasitemia. Medscape
13) Why is spleen status important?
Without a spleen, parasite clearance is impaired and disease can be severe, guiding longer therapy and closer monitoring. Medscape
14) Can I donate blood after babesiosis?
You should not donate while infected or shortly after recovery; blood centers screen for risk to prevent transfusion-transmitted infections. Medscape
15) What’s the single most effective prevention step?
A bundle: permethrin-treated clothing, EPA-registered repellent on skin, and prompt full-body tick checks after outdoor exposure. CDC
