Prevalence of and risk factors for feline Tritrichomonas foetus and giardia infection.

Data were gathered for 117 cats from 89 catteries at an international cat show to examine prevalence and risk factors for feline Tritrichomonas foetus and Giardia infection. Prevalence of T. foetus was 31% among cats (36 out of 117) and catteries (28 out of 89) based on results of fecal smear examination (5 out of 36), fecal culture in modified Diamond's medium (9 out of 36), fecal culture in In Pouch TF medium (20 out of 36), or PCR amplification of the ribosomal RNA gene from feces with T.
