The antibiotic-resistant isolates of M. haemolytica and P. multocida exhibit comparable growth rates as their respective parent strains. The CFU/ml for antibiotic-sensitive (♢) and antibiotic-resistant (△) M. haemolytica and antibiotic-sensitive (○) and antibiotic-resistant (□) P. multocida when grown in BHI broth as monocultures were determined. The results are the mean CFU/ml from three independent experiments (±the standard deviations [SD]). There was no statistically significant difference (P > 0.05 based on repeated measures of ANOVA) between the CFU/ml for the antibiotic-resistant and antibiotic-sensitive isolates.
