Abstract

Porphyromonas gulae, a suspected pathogen for periodontal disease in dogs, possesses approximately 41-kDa fimbriae (FimA) that are encoded by the fimA gene. In the present study, the association of fimA genotypes with mitral regurgitation (MR) was investigated. Twenty-five dogs diagnosed with MR (age range 6-13 years old, average 10.8 years) and 32 healthy dogs (8-15 years old, average 10.8 years) were selected at the participating clinics in a consecutive manner during the same time period. Oral swab specimens were collected from the dogs and bacterial DNA was extracted, then polymerase chain reaction analysis was performed using primers specific for each fimA genotype, with the dominant genotype determined. The rate for genotype C dominant specimens was 48.0% in the MR group, which was significantly higher than that in the control group (18.8%) (P < 0.05). These results suggest that P gulae fimA genotype C is associated with MR.
