N=136. n1=number of E. coli isolates from beef sample, n2= number of E. coli isolates from sheep meat sample. N1= Total number of E. coli isolates from beef sample, N2= Total number of E. coli isolates from sheep meat sample. Amp=Ampicillin, Ery=Erythromycin, Str=Streptomycin. aP values were calculated using an unreplicated two-way analysis of variance (ANOVA). P values less than 0.05 are bolded. # Variance between beef and sheep meat. ## Variance among the four districts under study.
