  The prevalence of Egg Drop Syndrome 1976 (EDS`76) virus antibody among various species of village poultry in north-eastern Nigeria was determined using Haemagglutination Inhibition (HI) test. These species included: chickens, ducks, guinea-fowls, turkeys and quails. The birds had no history of vaccination against the EDS`76. The results of the antibody survey showed that active and passive HI antibodies to EDS`76 viruses were prevalent in the sera and embryonated eggs of the different species of village poultry. Antibody prevalence against the virus was noted as follows: chicken sera (1.4%), chicken embryonated eggs (17.7%), guinea fowl sera (22%), guinea fowl embryonated eggs (25.2%), duck sera (42%), duck embryonated eggs (78%), turkey sera (85.7%) and quails sera (3.7%) none of the quails embryonated eggs had antibody to EDS`76. Of the 376 sera and 328 embryonated eggs tested an overall prevalence of 52/323 (16%) and 75/328 (23%) were recorded respectively. Majority of the positive sera and embryonated eggs tested 37/52 (77%) and 44/75 (57%) reacted to high titres ≥1:20 and ≥1:4, respectively indicating considerable activity of the virus among village poultry in the study area. It is suggested that in apparent infections with the virus could be one of the factors responsible for the low egg production usually observed in village poultry.

  Retrospective survey for prevalence of Morbillivirus antibody was carried out in 400 camels slaughtered in Maiduguri municipal abattoir using Complement Fixation Test (CFT). The results of the retrospective study showed that complement fixing antibodies to Morbillivirus were prevalent in the slaughtered camels tested. An overall prevalence rate 154 (38.5%) of morbillvirus antibodies was found among the animals screened, 232 (58%) showed evidence of anti-complementary activities and 14 (3.5%) were negative. The survey of slaughtered camels in the municipal abattoir revealed increased camel importation during the months of April to May which coincided with the prolonged hot-dry season in the study area. The rainy season which coincided with the months of July to September is characterized by a decrease in the number of imported camels to Nigeria. It is therefore important that camels be included among the group of animals to be monitored for the activities of Morbillivirus like RPV/PPRV and to define their role in the epidemiology of the disease in Nigeria and elsewhere.

  Plants are used widely in the tropics and sub-tropical Africa and Asia for the treatment and cure of various illnesses such as malaria, diarrhoea, burns, gonorrhoea, stomach disorders and other infectious diseases; among which are livestock and poultry related diseases. Present studies on the preliminary phytochemical composition of the leaf of this plant revealed the presence of flavonoids, tannins, saponins, phenols lectins, triterpenes and carotenoids among others. Studies on the swab content from the navel of the day old chicks of both strains (broilers and layers) had revealed the presence of several gram positive and gram negative organisms such as E. coli, Staphylococcus sp., Streptococcus sp., Proteus sp., Klebsiella sp. and Corynaebacterium. The susceptibility tests on the isolated organisms by the extract under study had showed an appreciable dose dependant zone of inhibition ranging from 13-25 mm. The activity of the extract (400 mg mL-1) can be favourably compared with that of the standard antibiotic-Oxytetracycline (10 mg mL-1) particularly between the E. coli and Streptococcus with 25:30 mm and 20:22 mm as inhibition zone respectively where no significant difference was observed. The extract exhibited a highest MIC of 12.5 mg mL-1 against Staphylococcus sp., while concentration of 25.0 mg mL-1 was noted as the MIC values against both E. coli and Streptococcus sp.
