n1=number of E. coli isolates from the beef sample, n2=number of E. coli isolates from sheep meat sample. Amp=Ampicilin, Ery=Erythromycin, Str=Streptomycin, Gen=Gentamycin, Cip=Ciprofloxacin, Col=Colistin, Lev=Levofloxacin, Cot=Cotrimoxazole. 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 antibiotic-resistant genes.
