Serological Screening Suggests Extensive Presence of Mycoplasma gallisepticum and Mycoplasma synoviae in Backyard Chickens in Southern Mozambique

摘要

A total of 459 serum samples from unvaccinated backyard chickens originating from 4 villages in Mandlakazi district, Southern Mozambique, were tested for the presence of Mycoplasma gallisepticum and Mycoplasma synoviae antibodies through commercial enzyme-linked immunoabsorbent assay [ELISA] kits. Anti-MG and anti-MS antibodies were detected in all villages surveyed and the overall seroprevalence was 48.8% [95% CI 39.1–57.8] and 84.5% [95% CI 76.8–90.4], respectively. The risk of being seropositive for both diseases was higher [P < 0.05] in Chidenguele village than other villages. It is concluded that MG and MS serum antibodies are present in backyard chickens.
