  A cross-sectional study was conducted from July 2013 to March 2014 to determine the prevalence of Infectious Bursal Disease (IBD) in 5 Local Government Areas (LGAs) of Gombe State, Northeastern Nigeria. A multi-stage random sampling technique was employed in the selection of 3 districts within each of these LGAs and 10 households within each selected district with moderate number of village chicken growers within the age range of 12-16 weeks old were selected. A total of 1500 cloacal samples comprising 651 males and 849 females were collected and tested for IBD antibodies using Rapid IBD Antigen Detection Test Kits (RADTK). Of this, 953 (63.5%; 95% CI: 61.06-65.94) were positive for the disease. A high prevalence of 84.4% (95% CI: 81.8-87.0) was obtained during the rainy season as compared with 40.3% (95% CI: 36.8-43.8) in the dry season (p<0.05). Males had a slightly higher prevalence of 59.9% (95% CI: 56.1-63.7) as compared with the female birds 52.2% (95%CI: 48.8-55.6) (p>0.05). Based on the LGAs, the prevalence ranges from 69.3% (OR = 1.45, 95% CI: 0.10-2.80) in Gombe to 61.0% in Funakaye LGA (p>0.05). Urban region had high prevalence of 37.6% (OR = 2.6; 95% CI: 1.79-3.41) as compared with 26.3% in the rural areas (p<0.001). It was concluded that IBD is endemic in Gombe State particularly within the urban city. Therefore, appropriate control and preventive measures were highlighted to mitigate the resultant economic losses to the backyard poultry farmers and halt further escalation of the disease.

  This study was conducted to investigate the prevalence of helminths of Muscovy ducks slaughtered at six poultry dressing slabs (N = 600) within Gombe metropolis by postmortem and parasitological examination of gastrointestinal tracts and trachea. A total of eight Nematode species were identified in this present study with an overall prevalence of 98.2%. Two nematode species recovered from the intestine were Ascaridia galli 514 (85.67%) and Trichostrongylus tenus 18 (3.00%). Heterakis gallinarum 477 (79.50%), Subulura brumpti 242 (40.33%), Capillaria contorta 221 (36.83%) and Capillaria annulata 131 (21.83%) were recovered from the caecum while Tetrameres fissipina 5 (0.83%) was recovered from the gizzard and Syngamus trachea 4 (0.67%) was recovered from trachea. The prevalence of single infection with nematode species (67.2%) and was higher than mixed infection (32.8%). A total of three 3 Cestode species were recovered from the small intestine with an overall prevalence of 20.3%. Cestode species identified include Raillietina echinobothrida 62 (10.33%), Raillietina tetragona 50 (8.33%) and Hymenolepis cantaniana 10 (1.67%). The prevalence of mixed infection (17.0%) with cestodes was higher than single infection (3.3%). This study revealed that the prevalence and species distribution of nematodes was higher than cestodes in the study area. This study provides baseline data on prevalence and species distribution of helminths of Muscovy ducks in Gombe. There is therefore the need for further studies on epidemiology and economic significance of helminths of Muscovy ducks under the traditional free range management system.
