Critical role of CfrB in Campylobacter-host interaction. (A) Effect of the CfrB mutation on colonization of chickens by C. jejuni JL11 and C. coli JL170. The experiment included two groups, and chickens in each group (15 birds) were inoculated with a 1:1 mixture of a specific Campylobacter strain and its isogenic cfrB mutant. Fecal samples were collected by cloacal swabs and used for CFU enumeration. Each bar represents the mean log transformed CFU of each strain in each group at the indicated days postinoculation (DPI). The broken line indicates the limit of detection. (B and C) Inactivation of CfrB abolishes C. coli JL170 colonization of chickens. The experiment included three groups of birds. The first two groups of birds were inoculated with JL170 or its isogenic cfrB mutant (JL170 CfrB−) (B), while the third group was infected with a 1:1 mixture of the two strains (C). For each group, six birds were euthanized and the cecal contents were collected at the indicated DPI. Each symbol indicates the log number of CFU/g of cecal contents for a single chicken. The horizontal bars indicate the means of groups at the indicated times. The broken line indicates the limit of detection. (D) Inhibitory effect of CfrB-specific antiserum on FeEnt-mediated growth promotion in Campylobacter. CfrB antiserum, MOMP antiserum, <t>preimmune</t> serum, or PBS was mixed with JL11 and JL170 cells for a modified growth promotion assay as described in Materials and Methods.

Article Snippet: Prior to the assay, the CfrB-specific rabbit antiserum, the preimmune control rabbit serum, and the major outer membrane protein (MOMP) rabbit antiserum specific for Campylobacter (kindly provided by Qijing Zhang, Iowa State University) were heat inactivated at 56°C for 30 min. To evaluate the inhibitory effect of anti-CfrB serum on CfrB function, 1 ml of MH broth grown log-phase culture of each Campylobacter strain was mixed with 1 ml of either CfrB antiserum, preimmune serum, MOMP antiserum, or phosphate-buffered saline (PBS) and then added to 23 ml of MH agar containing 20 μM DFO and poured into petri dishes for solidification.
