| Popis: | A serological survey was conducted on rural and intensive poultry production during the 1995 rainy season and 1996 dry season in Senegal Cap-Vert area in order to determine the prevalence of mycoplasmoses, fowl typhoid and pullorum disease, Newcastle, infectious bursal and infectious bronchitis diseases. One-hundred-sixty and 100 rural poultry were sampled during the rainy and dry seasons, respectively, whereas 84 and 88 intensive farm flocks were sampled during the rainy and dry seasons, respectively. Mycoplasma infections were common among rural poultry: 49 and 43% during the rainy and dry seasons, respectively, for Mycoplasma gallisepticum; 50 and 66% during the rainy and dry seasons, respectively, for Mycoplasma synoviae. Salmonella gallinarum pullorum infections were less common (5 and 9% during the rainy and dry seasons, respectively). These infections affected mainly layer hens in intensive farming: during the rainy and dry seasons 4-5% of the flocks were infected with Mycoplasma gallisepticum, 20-28% with Mycoplasma synoviae and 41- 45% with Salmonella gallinarum pullorum. The viral diseases studied here were frequently encountered in rural poultry breeding (infectious bursal disease 76% and infectious bronchitis 89%). A seasonal variation was observed for the Newcastle disease only, as it occurred more frequently during the dry season (98% vs. 84% during the rainy season). In intensive poultry farming this disease was rather rare and tended to occur during the dry season (11% of flocks were infected). Seroprevalences of infectious bursal and infectious bronchitis diseases were high and relatively constant during the study period (69 and 46% during the rainy and dry seasons, respectively, for the infectious bursal disease and 63 and 54% for infectious bronchitis). |
