Campylobacter Blood Agar

Campylobacter blood agar (CVA), is a selective medium that allows for the primary isolation from stool specimens of Campylobacter Jejuni. Dekeyser et al. Dekeyser et al. reported that Campylobacter jejuni was isolated from patients suffering from diarrhea and acute gastroenteritis using a filtration method and a selective media with antimicrobials. Skirrow, however, reported that a select medium containing three antimicrobics was used for isolation. Blaser and colleagues reported that they were able to isolate C. jejuni from feces using a selective medium that contained four antimicrobials: amphotericin (vancomycin), polymyxin B and trimethoprim. Reller et al. in 1983 also introduced a better selective medium containing cefoperazone and Vancomycin. This combination of antimicrobials allowed for better suppression of normal fecal bacteria, thereby allowing for better isolation of C.jejuni from the fecal specimen.
