Occurrence of Co-Infection of Helicobacter pullorum and Campylobacter spp. in Broiler and Village (Indigenous) Chickens

Abstract

The reports on prevalence of Helicobacter pullorum in broiler chickens are rather limited and lacking in village chickens. This study aimed to determine the occurrence of H. pullorum in broiler and village chickens in Selangor, Malaysia and to report the detection of co-infection of H. pullorum and Campylobacter spp. in these chickens. Village (indigenous) chickens were sampled in five markets and broiler chickens from six farms in different localities. Cecal contents were aseptically obtained from the chickens and subjected to three cultural methods. The isolates were identified by biochemical tests and confirmed using a species-specific PCR assay. Helicobacter pullorum were isolated from 25% village chickens and 24.6% broiler chickens, with an overall occurrence of 24.7%. Eleven (50%) of these positive chickens (nine in broiler and two in village chickens) showed co-infection with Campylobacter spp.
