Bile resistance. The ability of C. jejuni chicken isolates (RO14, RO19, RO24, RO29, RO37) and C. jejuni 81-176 to survive to bile salts in Mueller Hinton medium was studied. Following agar growth bacteria were transferred into 50 mL of medium containing 0.5% bile salts. Samples were removed after 24 h and diluted prior plating. The surviving cells were counted after 42 h incubation. The experiments were done in triplicates and Student t test was used for statistical significance.
