The study determined the seroprevalence of S. gallinarum infection in freerange chickens in Nasarawa State, Nigeria. A total of 2772 serum samples collected from free-range chickens in 12 selected villages/towns in Nasarawa State were screened for specific antibodies against S. gallinarum by the rapid serum agglutination method. Overall, 236 (8.5%) of the chickens had detectable antibodies against S. gallinarum. Nasarawa South Senatorial Zone had a significantly higher (p<0.05) antibody prevalence of 109 (9.5%) when compared with Nasarawa North, 59 (8.5%) and Nasarawa West, 68 (7.2%). There was significant difference (p<0.05) in S. gallinarum antibody prevalence in chickens sampled from individual villages/towns, with Assakio, Keana and Wamba having significantly higher antibody prevalence rates of 17 (21.3%), 21 (21.0%) and 16 (20.0%), respectively. A significant difference (p<0.05) was observed in the prevalence of S. gallinarum antibody in the sampled chickens in relation to age, and prevalence was found to be higher (p<0.05) in the older.birds Thus chickens of age greater than 34 weeks and 28-34 weeks had antibody prevalence of 47 (13.4%) and 57 (10.0%), respectively. S. gallinarum antibody prevalence was significantly higher (p<0.05) in the rainy season (June to October) 126 (10.5%) with the highest infection peak in September, when compared with the dry season (December to May), 110 (7.0%). The layer chickens had a significantly higher (p<0.05) antibody prevalence of 138 (19.1%) compared with cockerel, 60 (5.3%) and pullets, 38 (4.1%). The detection of S. gallinarum antibody in theseunvaccinated apparently healthy chickenssconfirms the presence of fowl typhoid.Since these birdss are usually managed under the extensive system, they could contribute to further spread of the infection in the environments. This could threaten the development of poultry industry in Nasarawa State, Nigeria. [ABSTRACT FROM AUTHOR] |
