Abstract: In this study, it was aimed to determine the presence of Brachyspira pilosicoli colonization in
dogs, to determine its prevalence and to investigate the relationship between colonization and
various physiological, pathological and behavioural variables such as diarrhoea, age, sex and
contact with other animals. For this purpose, faecal specimens were collected from 192 dogs (96
with diarrhoea and 96 healthy controls). Faecal samples were specifically cultured for
Brachyspira species. 10 presumptive Bra-chyspira spp. isolated, biochemical and enzymatic
properties of the isolates were evaluated and identified using PCR. The prevalence of
B.pilosicoli was found as 4.68% (n = 9). The relationship between diarrhoea and B.pilosicoli
colonization in dogs has been shown to be statistically significant (P <0.001). The presence of
contact with other dogs and B.pilosicoli colonization were statistically significant (P = 0.033).
There was no statistical relationship between age and sex with colonization |
