Specific Infections by Free-Living Amoebae
Free-living amoebae are a large group of unicellular eukaryotes, commonly found in aquatic environments. While they are generally harmless, there are certain species of amoebae that are capable of causing disease in humans. Below are some of the specific infections that can be caused by free-living amoebae:
- Granulomatous amoebic encephalitis (GAN): This is a rare, but fatal form of encephalitis caused by the amoeba, Naegleria fowleri, which is found in warm, fresh-water bodies. It is usually contracted when people swim and inhale water that has been contaminated with the amoeba.
- Cutaneous amoebiasis: This is a skin infection caused by the amoeba Acanthamoeba. It is usually contracted by coming into contact with contaminated soil or water. Symptoms include skin lesions that are itchy, red, and scaly.
- Entamoeba histolytica: This is a strain of amoeba that is responsible for a parasitic infection of the intestines. Symptoms include abdominal pain, diarrhea, and weight loss. If the disease is not treated, it can lead to serious complications such as liver or intestinal abscesses.
- Acanthamoeba keratitis: This is an eye infection caused by the amoeba Acanthamoeba. It usually occurs in contact lens wearers, since the amoeba can adhere to the lens and be transported into the eye. Symptoms include eye pain, redness, and blurred vision.
- Balamuthia mandrillaris: This is an amoeba that can cause encephalitis in humans. It is most commonly contracted by coming into contact with contaminated soil or water. Symptoms may include headache, confusion, and seizures.
It is important to be aware of these specific infections, as they can be serious, and even life threatening. If you think that you may have been infected, it is important to seek medical advice immediately.
