title: Comparison of two selective media for the isolation of Campylobacter species from a pediatric population in Mexico.
abstract: Two selective media for the isolation of Campylobacter species, a blood containing medium (CampyBAP) and blood-free, charcoal based formulation (CCDA) were compared for the ability to isolate Campylobacter species during a 1-year period. Of the 1,132 stool samples cultured during the study, 42 Campylobacter species were recovered using both media (3.7% yield). CCDA was better than CampyBAP for isolating C. jejuni subsp jejuni (18/20 vs 8/20, P = 0.002) and for all isolates, CCDA was superior over CampyBAP (39/42 vs 13/42, P < 0.0001). Overall, CCDA is a superior medium compared with CampyBAP for isolating Campylobacter species in our study population.
