Occurrence of Salmonella species in the Environment of broiler Poultry Farms of Jabal Awliya Locality, Sudan.

Abstract

The aim of this study was to detect the occurrence of Salmonella species in the environment of broiler poultry farms of Jabal Awliya Locality and to investigate the antimicrobial susceptibility of the isolates. A total of 162 samples were collected from water source, drinkers, feed, feeders, litter, dust, faeces, cloacal swabs, and hand swabs from workers from different 18 farms from April 2013 to February 2014. Samples were analyzed by using ISO 6975(2002) and confirmed by using API20E strips. The results showed that the overall prevalence of Salmonella spp was 10 (6.2%) recovered from 8(44.4%) farms. Isolates were collected from drinkers1 (10.0 %%), feeders 1(10.0%), faeces 1(10.0%), cloacal swabs 1(10.0%), dust 3(30.0%), and litter 3(30.0%), however, water source, poultry feed, and hand swabs of workers were free from Salmonella species. This study showed that all the isolates (100%) were sensitive to ciprofloxacin, cefixime, cefotaxime, and colistin followed by, chloramphenicol (90. %), co-tri moxazole (70.0 %), streptomycin (70.0%), gentamicin (70.0%), ampicillin (30.0%), tetracycline (30.0%), nalidixic acid (30%), while amoxicillin showed the highest resistant antibiotic. This study was done at the laboratory of the Microbiology department, Faculty of Medical laboratory Sciences, Al-Neelain University.
