Nematodes recovered from the hindgut of zebras were examined with scanning and transmission electron microscopy for microorganisms. Microorganisms were observed attached to the posterior extremities of two groups of nematodes, atractids and cyathostomes. Novel techniques were used to culture the microorganisms, and these included rinses to reduce contamination from hindgut flora and the design of the culture media. Electron microscopy revealed a flat bacterium not previously observed, as well as small rods and segmented filamentous bacteria. Culturing techniques resulted in isolation of a Propionibacterium species.
