  A study on seroprevalence, seasonal occurrence and clinical manifestation of Newcastle Disease Virus (ND) among rural household chickens and Live Birds Markets (LBM) was conducted using haemagglutination Inhibition Test (HI) and questionnaires. A total of 1, 208 chickens reared under extensive management system in four Local Government Areas (LGAs) of Plateau State were used for the study. The seroprevalence of ND virus antibodies in rural chickens showed that there was no statistically significant (p > 0.05) difference among the four LGAs and of the 1,208 sera tested, 51.9% had detectable antibodies to NDV but only 14.1% of the chickens had HI antibody titre of > 4log2 which was considered as protective. About 86.2% of the chickens sampled were at risk of suffering from clinical ND. Newcastle disease outbreaks occurred year round in the villages sampled with the highest incidence of 86.6% observed from November to March (Dry season) and September to October, 8.31% (Pre-dry season). During outbreaks of ND, infected birds exhibit the following major clinical signs; nervous signs (32.4%), weakness (16.6%), whitish/greenish diarrhea (16.2%), coughing/sneezing 13.6%, anorexia 9.39% and others 11.8%. It was concluded that the prevalence of ND in the four LGAs of Plateau State is high. At the time of the study over 80% of rural chickens in Plateau State were at risk of dying from ND when exposed to a virulent NDV. It is therefore recommended that vaccination and improved management practices as a means of prevention against ND before the period of outbreaks should be instituted.

  A study was conducted in Plateau State of Nigeria which has two distinct agro-ecological zones; a humid sub-temperate region in the North and a sub-humid hotter region that is part of the Northern Guinea Savanna ecological zone of Nigeria in the South. A sample of 1240 farmers from two Local Governments in each of the two ecological zones were surveyed to assess the poultry population and strains of birds as a prelude to the introduction of interventions for control of Newcastle Disease and other programs for improving rural poultry productivity. Results showed that the farmers owned an average of 20 chickens, 6 ducks, 0.3 turkeys, 1 pigeon and 1.2 guinea fowls per household. Each household reared two or more strains of chicken and most had different types of poultry in the same backyard. There were more Naked neck and long legged chickens in the hotter ecological zone but more Barred plumage strains in the cooler ecological zone.

  Smoked fish species, Clarias sp., Gymnarchus niloticus and Tilapia sp., sampled from the open markets in North-Eastern Nigeria were investigated for the presence and concentration levels of pesticide residues of DDT, dichlorvos and lindane. The GC-MS and GC-FID techniques were employed in the determination of the pesticide residue. The obtained results showed positive identification of op-DDT (2.844-4.220 μg g-1), pp-DDT (3.821-4.479 μg g-1), dichlorvos (2.844-4.220 μg g-1) and lindane (3.479-9.878 μg g-1). Gymnarchus niloticus showed consistently higher pesticide residue levels in the studied smoked fish samples followed by Clarias sp. and then Tilapia sp.

  A 10 years, 2001 to 2012, study in a multispecies farm was undertaken to investigate the cause of mortality in Japanese quails (Coturnix coturnix japonica) reared on deep litter in Vom, Plateau State, Nigeria. Clinical signs and gross lesions were also recorded. One viral, four bacterial, two protozoan and three miscellaneous conditions were the cause of mortality. Infectious diseases included Newcastle disease, salmonellosis, colibacillosis and pasteurellosis. The diseases caused 1,411,079 deaths in chicks, growers and adult quails. Smothering was the major (303,600; 21.52%) cause of mortality in chicks followed by salmonellosis (285,360; 20.22%) and Newcastle disease (237,600; 16.84%) in adults. Coccidiosis and histomoniasis caused mortality of 0.60% (8,400) and 0.94% (13,200) in growers and adults, respectively. The signs and gross lesions caused by the diseases encountered in the quails were similar to those reported previously in chickens. It was concluded that Japanese quails are susceptible to diseases affecting chicken and they exhibit similar signs and develop similar gross lesions. As the infectious diseases diagnosed in the quails were also encountered in chickens concurrently reared on the same farm the quails could have been the source of the pathogens for the chickens. Adequate biosecurity and control measures currently practiced in chickens would prevent mortality and spread of disease in quails.
