  Most brucellosis related studies in Nigeria is mainly in the cattle population. Brucellosis in small ruminants may be of greater public health concern in view of the socio-economic role of small ruminants in Nigeria. This study was carried out to generate a base-line data of brucellosis in sheep and goats in Kaduna North Senatorial District of Kaduna State, Nigeria. In this study, 72 and 122 milk samples were collected from apparently healthy sheep and goats, respectively within the months of April- May. Milk samples were collected from lactating sheep and goats and subjected to the Milk Ring Test (MRT). From the milk samples collected 13(18.1%) and 32(26.2%) were positive for Brucella antibodies. Though the prevalence in goats was higher compared to sheep but this was not statistically significant (p>0.05). A high prevalence of Brucella antibodies in the milk of sheep and goats necessitates government intervention for an effective and holistic control of brucellosis in Nigeria. High risk groups and the general public should further be enlightened on the health hazards of the disease and the risk of interspecies transmission of brucellosis.

  This report describes an outbreak of an acute, highly lethal, Newcastle Disease (ND) in two broiler flocks that were intensively managed and vaccinated against Newcastle disease. The broiler flocks (325) were four weeks and (450) were six weeks old at the time of the outbreak. Clinical characteristics of the disease included a 100% morbidity, increasing high mortality i.e. 40 birds (day one), 70 birds (day two), 180 (day three) and the entire flocks consisting of 755 birds were lost by the fifth day. Clinical features observed included severe depression, gasping, anorexia, cyanosis and subcutaneous haemorrhages of the legs and shank. Gross lesions seen were severe congestion of skeletal muscles and visceral organs and severe haemorrhages and congestion of the proventriculus, cecal tonsils and trachea, air saculitis with severely congested and pneumonic lungs were observed as well. Ten cloacal swabs from dead and sick birds were tested using a Rapid Newcastle Disease and Avian Influenza Antigen Detection Test Kits. This Chromatographic- immunoassay tested positive for ND and negative for AI confirming the presence of ND viral antigen. Four dead and live birds taken to National Veterinary Research Institute (NVRI) Vom, Nigeria for further confirmation were tested using rapid test kit, haemagglutination inhibition test and viral isolation. These tests were also negative for AI but positive for vvND. Clinical signs and gross lesions of ND and Highly Pathogenic Avian Influenza (HPAI) seem not to be distinguishable in the field. This is likely going to affect disease reporting and actions to be taken. Vaccination against ND should not be totally relied upon especially when birds are not seromonitored pre and post vaccination.

  Sixteen lactating Bunaji dairy cows were screened for bovine Tuberculosis (bTB) using one-step Anigen® Rapid Bovine Tuberculosis Antibody Test (IQRT) specific for Mycobacterium bovis (M. bovis) antibodies. About 62% (10/16) of the lactating Bunaji cows screened were positive for antibodies to M. bovis. Six out of the ten positive cows were randomly selected culled and postmortem examination was conducted on them for the presence or absence of bTB gross lesion. Gross lesion was not observed in any of the culled cows examined. Though, the cows were exposed to M. bovis, probably infection is inapparent because bTB is a progressive and chronic disease.

  This study was carried out to detect exposure to Mycobacterium bovis (M. bovis) in four dairy herds consisting of a total of 200 cows, aged between 21/2-10 years. The cows were of various breeds, namely: white Fulani (Bunaji), crosses of white Fulani and sokoto gudali, white Fulani and Friesian, semi-intensively managed and producing milk for yoghourt production in Kaduna and environs. Anigen® Rapid Bovine Tuberculosis Antibody Test (IQRT) specific for M. bovis antibodies in sera of cows were used in this study. The result showed 17.5% (35/200) positive for antibodies to M. bovis. Fresh milk from cows positive to the IQRT and also packed yoghourts made from milk obtained from those positive and negative cows in the sampled dairy herds were collected and subjected to Ziehl-Neelsen Stain (ZNS) in order to detect bacilli in fresh milk and packed yoghourts. The result obtained 17.1% (6/35) of these cows were shedding the bacilli in fresh milk while no bacillus detected in the packed yoghourts. The result showed that IQRT was sensitive in detecting M. bovis before they start shedding in milk while ZNS technique was found to be potentially useful in detecting M. bovis infected lactating cows that are shedding the bacilli in milk. This study has shown that apparently healthy lactating cows may shed viable M. bovis in milk there by posing a serious public health problem where unpasteurized milk is consumed. This calls for the need to ensure that only non-positive milking cows are milked for human consumption and the IQRT is the best of choice to determine that.
