It provides a comprehensive review of the epidemiology, diagnosis, and management of opportunistic infections and presents strategies for infection prevention and control. [books.google.com]

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]

• Fever

  trench fever, human erlichiosis; and more. [books.google.com]

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

  The amoebae may be transported via the blood to the liver and other organs and usually do NOT give rise to a high temperature (this can be useful ie bloody diarrhoea with a fever suggests a bacterial infection) and a seriously debilitated condition. [netdoctor.co.uk]

  Patients with an amebic abscess of the liver complain of pain in the chest or abdomen, fever, nausea, and tenderness on the right side directly above the liver. [medical-dictionary.thefreedictionary.com]

  However, your doctor might give you advice about increasing fluid intake to avoid dehydration, and non-prescription painkillers might be used to relieve pain and fever. [your.md]

• Fatigue

  Symptoms of Amebiasis Diarrhea, possibly containing blood or mucus Rectal pain during bowel movements (tenesmus) Intestinal gas (excessive flatulence) Severe abdominal cramping and tenderness Excessive gas Loss of weight High fever Fatigue Nausea and [healthcommunities.com]

  Weight loss and fatigue can also occur. If the amoebic dysentery goes untreated, it can progress to extraintestinal amoebiasis, although this is rare. [study.com]

  But it may cause milder chronic symptoms of: frequent loose stools abdominal pain cramps fatigue intermittent constipation diarrhoea with abdominal swelling flatulence. Amoebae are parasites that are found in contaminated food or drink. [netdoctor.co.uk]

  These could include: Diarrhea Dysentery Fatigue Fever Excessive gas Rectal pain, occurring with bowel movement Vomiting It is possible for the protist to enter the circulatory system and continue to invade other organs, such as the liver, lungs, and sometimes [dovemed.com]

  Some early symptoms might include a combination of the following:• Severe headache• Stiff neck, or neck pain with neck movement• Sensitivity to light• Nausea and vomiting• Unusual fatigue• Fever• Difficulty walking or talking• Sudden one-sided weakness [slideshare.net]

• Anemia

  Wasting of the body (emaciation) and anemia can occur in people with chronic infection. Sometimes large lumps (amebomas) may form inside the large intestine (colon). In some people, the amebas spread to the liver where they can cause an abscess. [msdmanuals.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]

Etiology and Incidence Two of the eight known species of Acanthamoeba, A. castellanii and A polyphaga, are responsible for most infections. [eyewiki.aao.org]
