ISOLATION AND CHARACTERISATION OF BACTERIA ASSOCIATED WITH HAWKED SUYA- MEAT (CASE STUDY OF ENUGU)

Thesis Abstract

This project work is carried at the isolation and characterization of pathogenic bacteria from hawked suya meat, were bought in full from the sellers and was collected in raps of aluminum foil. It was then taken to the laboratory for analysis the samples were homogenized and serial dilution of the sample was made out using 5 ml sterile pipette and test tubes. The dilution were then cultured on different media, macconkey agar, nutrient agar and blood agar end later incubated at 370c for 24 hours. Discrete bacteria colonies were observed and each colomy was gram stained and examined microscopically. Biochemical test were carried out to confirm the particular bacteria present. Bactering isolated were Staphylococcus aureus, Bacillus, lactobacillus, streptococcus and Escherichia coli. Most at this microorganisms isolated are pathogenic and are toxic when ingested in contaminated suya meat. They are capable of causing illness. For instance staphylococcus aureus produce air exotizcin and can with stand temperature of 1000c for 30 minutes. When ingested, if cause intoxication manifesting in 4-5 hours with acute diarrhoes vomiting and gastroertrities lasting 6-8 hours.
