Prevalence and Antimicrobial Resistance of Salmonella species Isolated from the Environment of Poultry Farms in Khartoum North Locality, Sudan

Abstract

A total of 162samples were collected from different 18 commercial broiler farms in Khartoum North Locality to detect the prevalence and antimicrobial resistance of Salmonella species during the period from May 2013 to February 2014. Samples including (water, feed, dust, litter, cloacal swabs, faeces, and hand swabs from workers), and they were investigated by using ISO 6975: 2002, and confirmed by using API20 E strips . The results showed that 18(11.1%)from 162 samples were found to be contaminated with Salmonella spp. These were recovered from 13(72.2%) farms. 1(5.6%), 3(16.7%),0(0.0%), 3(16.7%), 2(11.1%), 6(33.3%), 2(11.1%),0(0.0%), and 1 (5.6%) were isolated from water source, drinkers, poultry feed, feeders, dust, litter, faeces, cloacal swabs, and hand swabs respectively. All isolates were sensitive to ciprofloxacin (100%), cefixime (100%), and cefotaxime (100%), followed by gentamicin (94.4%), chloramphenicol (88.9%), colistin (83.3), streptomycin (66.7%), co-trimoxazole (66.7%), nalidixic acid (61.1%), ampicillin (55.6%), tetracycline (55.6%), and amoxicillin (5.6% ) which showed the highest prevalent resistant antibiotic.
