abstract
The present study was done for epidemiological investigations of Buxtonella sulcata in buffaloes of Karnal district. Epidemiological factors like location, age, sex, housing and clinical manifestation (Diarrhoeic or non-diarrhoeic) were studied. A total of 400 faecal samples were collected and screened using sedimentation technique. Pearson’s chi-squared test was used to find out the relationship between various epidemiological factors and the presence of B. sulcata in the faecal samples. The overall prevalence of B. sulcata was 63.7% and in four blocks were Karnal 64.0%, Gharaunda 65.0%, Indri 65.0% and Nilokheri 61.0% of Karnal district. Sex wise prevalence in male and female were 76.13% and 60.25%, respectively. Age-wise prevalence between 1-6 months and above 6 months age of buffaloes was 64.28 and 63.15%, respectively. We studied the association of either Kutcha (mud) or Pukka (brick and concrete) floor on infection with B. sulcata and buffaloes kept on Kutcha floor showed 64.28% prevalence and those on Pukka floor showed 63.68% prevalence. We studied the association of B. sulcata infection with diarrhoea which revealed animals with diarrhoea were more positive 86.56% than those without diarrhoea 38.34%. The difference was significant.
