Isolation of Salmonella Sp. and E. Coli from Fermented Milk Product (Nono) in Kuje Area Council (Fct, Abuja, Nigeria) and their Antimicrobial Resistant Status
Main Article Content
Abstract
This study was undertaken to assess the incidence of antimicrobial susceptibility status of Salmonella species and Escherichia coli isolated from a fermented cow milk product (Nono) in Kuje, FCT, Abuja. For the purpose of this study, Kuje was divided into; Kuje North (KN), Kuje East (KE), Kuje West (KW), Kuje Central KC) and Kuje South (KS). In number, a total of 154 fermented samples of the products were collected for bacterial isolation and identification from the regions using conventional bacteriological identification methods. The identified isolates were tested for their antimicrobial susceptibility status using four different types of antibiotics by disc diffusion method. The prevalence of Salmonella sp. was 10/154, while that of E. coli was 18/154. The presence of Salmonella isolates was higher in those milk samples products where nearby stream was the primary source of available water for all routine domestic use including milk processing (KE and KN) respectively. All the salmonella isolates were found to be susceptible to gentamicin but 91.3% to amoxicillin, 90.2% to sulphamethoxazole-trimethoprim and 88.9% to tetracycline. Three of the Salmonella isolates showed multiple drug resistance to two drugs. The findings from this research showed that the fermented dairy milk product (nono) obtained from local processing households in Kuje, FCT, Abuja was contaminated with public health important bacterial species; Salmonella species and E. coli. Also of utmost importance is the resistance of the pathogens to certain antimicrobial drugs which call for attention. Therefore, in order to ensure safe quality of fermented milk products are supplied to the FCT, the respective stakeholders engaged in this business need to be educated in basic hygienic practices and the implication of poor sanitation on human health
