Abstract
In this study, prevalence of enteric bacteria in ready to eat suya and antibacterial activity of Tetrapleura tetraptera pod extract was carried out. The aim of this research was to isolate enteric bacteria from suya meats and determine the antibacterial potential of T. tetraptera against enteric bacteria. Standard microbiological methods were used to determine the total heterotrophic bacteria and coliform count of the suya samples using pour plate methods. Ethanolic extraction of pod of Tetrapleura tetraptera was done. The result of this study showed the total heterotrophic bacteria count (Log10 Cfu/g) ranged between 3.00±3.00 to 5.455606±2.50 (Log10 Cfu/g) while Total Coliform Count ranged from 3.00±0.50 to 4.921686±1.00 (Log10 Cfu/g). The bacterial
isolates isolated were Morgenella sp, Enterobacter sp, Pseudomonas sp, E. coli, Klebsiella sp and Bacillus sp. Phytochemicals screening showed the presence of saponin, te penoids, phenol, glycoside and alkanoids. Antibacterial screening showed that Tetrapleura tetraptera pod extracts possessed antibacterial activities against the test isolates with Klebsiella sp. Having 33.67mm for 100mg/ml while the minimum zone was recorded in Escherichia coli with 6.33mm for 75mg/ml concentration of extract. This finding also suggests good antibacterial potential of the pod extracts of Gum tree
