Despite this response, some trophozoites are able to reach, adhere to and penetrate the epithelium. Naegleria fowleri are found world wide in warm freshwater, either naturally geothermic pools or warm bodies of water created by industry such as industrial cooling water (4). Although they ideally grow at 37 o C, the temperature of their human hosts, below 27 o C, N. fowleri are able to survive by encysting. There have been 32 reported infections in the U.S. in the 10 years from 2001 to 2010. Naegleria fowleri is an etiological agent of primary amoebic meningoencephalitis in humans and laboratory animals. When first infected, the disease causes fever, headaches, and vomiting. Like It is typically free living, but is a thermophilic parasite if it encounters the right host. The sizes of the trophozoite forms range from 15 to 25 m. Test. Naegleria fowleri is the aetiological agent of primary amoebic meningoencephalitis (PAM). Naegleria fowleri is the aetiological agent of primary amoebic meningoencephalitis (PAM). During the initial stages of infection, the host response is initiated by the secretion of mucus that traps the trophozoites. It then travels to the brain, where it destroys brain tissue, causing swelling and death. [12] Flashcards. Although humans are a known host of N. fowleri, since infections are so rare, it is expected there is an alternative, primary host such as fish, amphibians or reptiles. N. fowleri are known parasitize fish and antibodies to different Naegleria species have been found in many wild animals (3). The results indicate that N. fowleri secretes a cysteine protease with the capacity to destroy host tissue, which is not thermotolerant to temperatures above 30 degrees C.
