Abstract:
Asurvey was carried out to estimate the prevelance of Salmonella spp and risk factors in Omdurman localities (Karari,Ombada and Abosyede)-Khartoum state.Atotal 0f 158 random samples of feces(100 samples and milk 58 samples) were collected from cattle.Isolation and identification of Salmonella spp were done.The total viable count(TVC)was also used.Sixty three out of 158 collected samples were positive to Salmonella spp.In fecal samples 40% were positive for isolated bacteria .The higest infection in milk samples were 44% in Karari and lowerst infection 35% in Abosyede.Statistically ,there was no significant difference(p≤0.05).The TVC revealed the highest contamination in fecal samples (2.00±1.22 log 10 cfu/g) while lowest contamination in milk(2.09±0.40 log 10 cfu/g).Risk factor that showed significant association in Salmonella infection was source of animals (OR=0,p-value=0.04,CI95%=0.00-0.95) and using outside bulls(OR=33,P-value=0.04,CI95%=1.04-1042.24).The presence of relative high level of Salmonella ssp in fecal samples and milk in this locality indication of bad hygienic status in these dairy farms.
