Prevalence of potentially pathogenic enteric organisms in clinically healthy kittens in the UK.

Abstract

Faecal samples were collected from 57 clinically healthy kittens presented for initial vaccination, in the UK. Routine bacteriological examination identified Salmonella species in one and Campylobacter species in five samples. Polymerase chain reaction (PCR) detected the presence of Campylobacter species in a further four samples. Routine parasitological examination revealed Toxocara species ova in nine (including four kittens stated to have been administered an anthelmintic) and Isospora species in four samples. No Giardia or Cryptosporidium species were detected by routine methods. A Giardia species enzyme-linked immunosorbent assay (ELISA) test kit designed for use in cats was positive in three kittens. A similar test kit designed for use in humans was negative in all samples and produced negative results even when known positive samples were tested. Potentially pathogenic enteric organisms were detected in 19 kittens by routine methods and 26 (prevalence 45%) by all methods. The high prevalence in asymptomatic kittens highlights the possibility that the detection of these organisms in kittens with gastrointestinal disease may be an incidental finding.
