title: Occurrence of Naegleria and Acanthamoeba in aquaria.
abstract: Samples from 24 aquaria were incubated at 28, 37, and 45 degrees C for the isolation of Naegleria and Acanthamoeba. Naegleria was the predominant genus (60.9%), whereas Acanthamoeba represented 15.5% of the isolates. No pathogenic N. fowleri was identified, although a high number of strains were closely related to this species. One isolate (Aq/9/1/45D) was compared with an aquarium isolate (PPMFB-6) from Australia. The Belgian isolate was found to be more related to N. fowleri, whereas the Australian isolate was closer to N. gruberi.
