Cerebrospinal fluid analyses revealed vacuolated macrophages that contained long parallel needle-like intracytoplasmic inclusions. Light microscopically, nerve cell bodies throughout the brain, ganglion cells within the retina and neurons in the myenteric plexuses were variably swollen and had pale granular to finely vacuolated eosinophilic cytoplasm.

We report cytologic observations and isolation of Mycoplasma felis in September 1992 from the lower respiratory tract of a 3-week-old captive serval (Felis serval) cub with pneumonia, in Florida (USA). Septic, neutrophilic inflammation with a large, monomorphic population of unique, pleomorphic, intracellular and extracellular rods was diagnosed from a transtracheal wash. Mycoplasma felis was the only bacterium isolated in significant numbers from the transtracheal wash.
