Stability of BCN E-760 resistance in vivo. (A) Shedding levels of various Campylobacter strains in chickens. Chickens in each group (10 birds/group) were inoculated with E-760 sensitive strain NCTC 11168, or one of E-760r mutants (JL341, K58, or JL106). All chickens received non medicated feed throughout the study. Each bar represents the mean of log10 CFUgram−1 feces ± standard deviation of Campylobacter colonized chickens in each group; (B) Instability of E-760 resistance in vivo. The percentage of E-760r population was calculated based on differential plating as detailed in Materials and Methods. Each bar represents the mean of percentage of the E-760r population of individual chickens ± standard deviation in each group.
