Bacteriological qualities and antibiogram study of bacteria from "suya" and smoked fish (Clarias gariepinus) in Dutsin-Ma, Katsina State, Nigeria

Abstract

Introduction: "suya" and smoked fish are cherished food delicacies in Nigeria, but can be a source of dissemination of Multi-drug Resistant (MDR)
bacteria. Moreover, there are limited studies on these MDR bacteria from Dutsin-Ma. Therefore, this study examined the bacteriological qualities and
antibiogram profiles of bacteria in these foods from this area in Nigeria. Methods: twenty samples of each of "suya" and smoked fish were collected
from the study areas and microbiologically analyzed. Total viable count, coliform count, characterization and identification of bacteria were carried
out by standard microbiological techniques. Results: findings revealed that "suya" samples possessed the highest total viable bacteria count (3.4×105
to 7.7×105
cfu/g) and coliform count (2.1×105
to 6.2×105
cfu/g). A total of 85 and 78 bacteria were isolated from "suya" and smoked fish samples
respectively. E. coli (24.7% and 24.4%) was the most frequently isolated from each sample respectively. Highest (66.7%) resistance to each of
cefuroxime, gentamicin, amoxillin/clavulanate and ciprofloxacin were observed among E. coli from "suya". MDR phenotypes commonly isolated was
resistance to ceftazidime, cefuroxime, ampicillin, ciprofloxacin, augmentin and nitrofurantoin. Conclusion: these studies showed the presence of
MDR bacteria in samples, hence, raise the need for improved production hygiene and public health awareness.
