Occurrence of Chlamydophila felis in a cattery in Osasco city, São Paulo state
AbstractChlamydophila felis is associated with upper respiratory tract infections. In the present study, 31 cats from a noncommercial shelter located in Osasco, SP, Brazil, were examined. The cats presented with clinical manifestations, which were classified from grade 1 to 4, with 4 indicating severe manifestations. In total, 16.13% of the cats presented with grade 1 severity of clinical manifestations, 25.81% presented with grade 2, 38.71% presented with grade 3, and 19.35% presented with grade 4. PCR was used to detect C. felis in samples taken from the oral mucosa and ocular conjunctiva of both eyes using sterile, dry cotton swabs. Overall, 58% of the samples were positive for C. felis. Of these animals, none showed clinical manifestations that were classified as grade 1, whereas 5.56% of cats were classified as grade 2, 61.11% were classified as grade 3, and 33.33% were classified as grade 4. The median clinical manifestation intensity score for the first group was 3 and ranged from 2 to 4. In the second group not positive for C. felis, 38.45% of the animals (5/13) presented with manifestations classified as grade 1, 53.85% (7/13) were classified as grade 2, 7.69% (1/13) were classified as grade 3, and no animals were classified as grade 4. The median clinical manifestation intensity score for the second group was 2 and ranged from 1 to 3. In this study, there was a high occurrence of C. felis in animals with clinical manifestations.
