title: Colonization of Campylobacter spp. in broiler chickens and laying hens reared in tropical climates with low-biosecurity housing.
abstract: The onset and prevalence of Campylobacter colonization in broilers and layers at commercial farms with low biosecurity in tropical climates were tested. Despite the presence of positive animals at the same farms, the broiler flocks tested negative until, on average, 21 days. Prelaying flocks showed a higher prevalence than laying flocks.
