PREVALENCE AND ANTIBIOTIC SUSCEPTIBILITY PATTERN OF STAPHYLOCOCCUS AUREUS ISOLATED FROM READY-TO-EAT FRESHWATER BIVALVE (CORBICULID HETERODONT) IN BAYELSA STATE, NIGERIA.
Journal Title: World Journal of Pharmaceutical and life sciences - Year 2018, Vol 4, Issue 7
Abstract
There has been a significant increase in antimicrobial resistance amongst foodborne pathogens over the past few decades. The increase in antibiotic resistance is associated with foodborne diseases resulting from the consumption of contaminated ready-to-eat foods. This study was carried out to investigate the prevalence and antibiotic susceptibility pattern of Staphylococcus aureus in ready-to-eat Corbiculid heterodont in Bayelsa State. A total of 53 samples were collected from 3 Local Government areas; Sagbama, Southern Ijaw, and Yenagoa and analyzed using standard microbiological methods. There was no difference (p ≥ 0.05) in the mean Staphylococcal count with Yenagoa having the lowest count (6.08±2.07 log10cfug-1); Sagbama (6.37±1.9 log10cfug-1) and Southern Ijaw, the highest (6.71±1.76 log10cfug-1). A total of 65 isolates of S. aureus were obtained with incidence ranging from 24.62% in Sagbama; 26.15% in Southern Ijaw and 49.23% in Yenagoa. Although isolates showed varied susceptibility pattern with a decreasing trend of resistance in this order; Amoxacillin and Ampiclox (100%) > Streptomycin (80.0%) > Rocephin (53.8%) >Zinnacef (33.8%) > Erythromycin (16.9%) > Ciprofloxacin and Trimethoprim-Sulfamethoxazole (15.4%) > Gentamycin (10.8%), no difference (p ≥ 0.05) was observed in the various local government areas sampled except for Ciprofloxacin (p ≤0.05). The extent of antibiotic resistance reflects the heterogeneous use and abuse of antibiotics in this region hence to adequately know the pattern of multidrug resistance, regular surveillance is required.
