Bacterivores are free-living, generally microscopic, which obtain energy and nutrients primarily or entirely from the consumption of bacteria. Many species of amoeba are bacterivores, as well as other types of protozoans. In common, all species of bacteria will be prey, but spores of some species, such as Clostridium perfringens, will never be prey, because of their cellular attributes.

In Microbiology

Bacterivores can sometimes be a problem in cycloheximide, the bacterivores will be inhibited and the bacteria will grow normally. For bacteria adsorbed into sediment, 2g of cycloheximide per 100g of sediment needs to be added. For experiments with spores (for example spores of C. perfringens), it is not necessary to add cycloheximide to the samples.
