Prevalence of Salmonella species in Cattle at Omdurman locality, Khartoum State

Abstract

A survey was carried out to estimate the prevalence of salmonella spp. in cattle at Omdurman localities (Karari, Ombada and Abosyede, Khartoum State. A total of 158 random samples (100 faecal samples and 58 milk samples) were collected from cattle. They were analyzed for the total viable count (TVC) and isolation and identification of Salmonella spp. Sixty three out of 158 collected samples were positive to salmonella spp. 40% from faecal samples were positive for isolated bacteria. The highest infection was in milk samples 44% from Karari and the lowest infection was 35% in Abosyede. Statistically, there was no significant difference (P? 0.05). The TVC revealed the highest contamination was in faecal samples (2.00�1.22 log10 cfu/g) while lowest contamination was in milk (2.09�0.40 log10 cfu/g). The presence of relative high level of Salmonella spp. in faecal and milk samples in these localities is an indication of bad hygienic status in these farms
