Acanthamoeba Infection

Acanthamoeba infection is a rare but serious condition caused by a microscopic amoeba known as Acanthamoeba. In this comprehensive guide, we’ll explore the types, causes, symptoms, diagnostic tests, and treatments for Acanthamoeba infection, breaking down complex information into simple, easy-to-understand language.

Types of Acanthamoeba Infection:

Acanthamoeba infection can manifest in various forms, with the most common being keratitis (eye infection) and granulomatous amoebic encephalitis (brain infection). These types often result from contact with contaminated water or soil.

  1. Keratitis: Affecting the eyes, Acanthamoeba keratitis can lead to severe eye pain and vision impairment.
  2. Granulomatous Amoebic Encephalitis (GAE): GAE is a rare but serious infection that affects the brain, often occurring in individuals with weakened immune systems.
