Sažetak
Chlamydia species in poultry can be zoonotic ; if not, it can affect the production performance of infected poultry. In the Philippines, there has been no report on the status of avian chlamydiosis in free-range chicken flocks, especially in the province of Bohol, where there is increased effort in conserving genetic resources and increasing the production performance of indigenous native chicken for free-range production. This study was conducted to assess the presence of avian Chlamydia species in free-range indigenous chicken flocks in Bohol province. Triple swabs (conjunctival, oropharyngeal and cloacal), litter and water samples were collected in each of the 16 flocks for Chlamydia spp. detection through real-time polymerase chain reaction (qPCR) assay for Chlamydiaceae 23S rRNA gene, C. psittaci incA gene, C. gallinacea enoA gene and C. avium enoA gene. A flock that was positive of any of the three samples was considered positive. Remarkably, 10 (62.50%) of the 16 flocks examined were positive for C. gallinacea and negative for the two other Chlamydia species – C. psittaci and C. avium. Interestingly, four flocks (25%) were found to have non-classified Chlamydia (Chlamydiaceae- positive ; C. psittaci-, C. gallinacea- and C. avium-negative) based on qPCR assay. The presence of primarily C. gallinacea in these flocks indicates that C. gallinacea is widespread in chicken. Furthermore, its presence in apparently healthy chickens requires further investigation to gain better understanding on chicken–C. gallinacea interaction and its impact on production performance of free-range indigenous chicken in the Philippines.
