Microbial Analysis and Antibiogram of Bacteria and Fungi Isolated from Meat Sellers Tables in Dutsin-Ma Metropolis, Katsina State

Abstract

The goal of the research project was to carry out microbiological analysis and antibiogram of bacteria and fungi associated with meat vendor tables in the city of Dutsin-Ma. This study made use of twenty samples in total. Five distinct locations at Wednesday Market and Darawa were chosen, and two samples from each table were taken using swab sticks. For analysis, the samples were then brought to the Federal University of Dutsin-ma microbiology laboratory department. The agars that were initially employed to isolate the bacteria and fungus were MacConkey, nutrient, mannitol salt, bile esculin, salmonella-shigella, eosin methylene blue, and potato dextrose agars. Bacterial species were identified using gram staining and biochemical tests while lactophenol cotton blue staining was used for the identification of fungal species. Bacterial isolates identified include Escherichia coli, Salmonella species, Klebsiella pneumonia, Bacillus subtilis, Streptococcus species and Staphylococcus aureus while the fungal isolates are Aspergillus flavus, A. niger, A. fumigatus, and Oidiodendron griseum. The antimicrobial susceptibility test findings showed that while some of the bacterial isolates were responsive to certain drugs, others were resistant. The results of this study's investigations therefore demonstrated how heavily polluted meat vendors' tables are with a wide variety of bacteria. This can be explained by the unsanitary procedures used in the meat sale industry as well as other environmental issues. Therefore, it is imperative that the government authorities tasked with these duties make sure that the vendors of these meat products adhere to standard and hygienic procedures. Raising public knowledge of the risks of foodborne illnesses associated with eating raw meats is another important goal of public health awareness campaigns.
