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).

Mycoplasma felis was the only bacterium isolated in significant numbers from the transtracheal wash.
