The present research was the first study to address the presence of potentially pathogenic free living amoebae in Kaleybar and Khodaafarin, East-Azerbaijan Province. [cwejournal.org]

Patients can present in a comatose state. As the amoeba causes extensive destruction of brain tissue, dramatic neurological presentations occur - eg, fitting, loss of body control, seizures, and hallucinations. [patient.info]

• Pain

  If you experience RSVP (redness, secretions, visual blurring or pain), return to your doctor of optometry immediately. [aoa.org]

  In addition to the anti-amoebic eye drops, you may be given anti-inflammatories or painkillers to help with the pain. You may also be given a dilating drop early in the infection to stop painful spasms of the coloured part of the eye, the iris. [moorfields.nhs.uk]

  People may have no symptoms or may have diarrhea, constipation, cramping abdominal pain, tenderness in the upper abdomen, and fever. [msdmanuals.com]

  A patient with amoebic dysentery can experience intense abdominal pain, periodic loose stools with blood and mucus, periodic constipation and fever. Weight loss and fatigue can also occur. [study.com]

Prognosis The prognosis for Acanthamoeba is worse than for many other types of infectious keratitis and prevention is therefore very important. However, especially if caught early, satisfactory outcomes can certainly be achieved. [eyewiki.aao.org]

Acanthamoeba species have been identified as the etiologic agents in 2 well-defined clinical entities, amebic keratitis and granulomatous amebic encephalitis (GAE). [pubmed.ncbi.nlm.nih.gov]

Preventing food and water from being contaminated with human feces is key to preventing amebiasis. Improving sanitation systems in areas where the infection is common can help. [msdmanuals.com]

Practice safer sex, including using condoms for anal contact and dental dams for oral contact to help prevent infection. Diagnosis Patient history and physical examination are needed. [healthcommunities.com]

Primary prevention Since treatment is toxic, lengthy, and not necessarily effective, prevention is essential. Contact lens wearers should be taught how to clean their contact lenses properly. [eyewiki.aao.org]
