Abstract

SUMMARY:

spp. are free-living predators that selectively feed on bacteria. Adherence of the bacterial food source to the trophozoite membrane is followed by internalisation and digestion. Through co-cultivation of and , individually, with and (despite the amoebicidal properties of the latter organism), specificity with regard to the preferred bacterial substrate was judged. and adhered almost immediately forming a multilayered mantle of bacilli around trophozoites of both species of amoebae. adhered to fewer trophozoites and in smaller numbers. was readily internalised after co-cultivation for 8 h, whereas and were not internalised even after co-cultivation for 24 h. These data suggest that the suitability of a bacterial food source for the spp. studied is associated not only with the proclivity with which the bacterial species binds to the trophozoite surface, but also with the rate of its internalisation.
