Bacteriologic and Histopathologic Studies in Pneumonic Lambs in Sokoto, North Western Nigeria

Mortality in lambs is known to be caused by pneumonia and other bacterial agents. Lamb pneumonia is an infectious disease of young lambs caused primarily by the bacterial organism Pasterella haemolytica. Lung samples recovered from dead lambs were tested bacteriologically and histopathologically to determine the associated bacterial agents as well as the type of pneumonia involved. Bacteria recovered from the samples included Pasteurella multocida, Staphyllococcus aureus, Arcanobacterium pyogenes, Closridium perfringes, Streptococcus, and Klebsiella pneumonia. Histopathologically, three types of pneumonia were recognized namely: Interstitial (46.51%), bronchopneumonia (32.56%) and fibrinous pneumonia (20.93%). It was observed that pneumonia is a major cause of mortality in lambs in Sokoto and pathogenic bacteria, particularly P. multocida are the most important bacterial agents in the pathogenesis of lamb pneumonia. It was also concluded that pneumonia affecting lambs can vary depending on agents of infection, environment, management, immune status of the lamb as well as treatment regime

Intercurrent antibodies to Mycoplasma bovis in cattle infected with haemoparasites in an institutional farm at Sokoto, Nigeria

A cross-sectional study of four institutional farms (Prison farm, Livestock Investigation and Breeding centre (LIBC), Usmanu Danfodiyo University Teaching and Research (UDUTRF) and Kebbe Cattle Ranch (KCR)) in Sokoto state, Nigeria, involving a total of 62 cattle comprising 49 females and 13 males was undertaken to determine the presence of Mycoplasma bovis antibodies. The cattle sampled were local breeds comprising Gudali, Rahaji, White-Fulani and their crosses. They were aged 1–10 years and were managed semi-intensively. Enzyme-linked immunosorbent assay (ELISA) was used for the detection M. bovis antibody. Of the 62 cattle screened, M. bovis antibody was detected in 41(66%). Also, 24 out of the 41 M. bovis positive cattle were found infected with haemoparasites. Similarly, 11 out of the 21 serologically negative cattle were infected with one or more haemoparasites. Seven (20%), 3(8.5%) and 7(20%) of the M. bovis positive cattle were infected with Babesia bigemina, Anaplasma marginale, and or B. bigemina and A. marginale respectively. Overall, 35 of the 62 screened cattle were infected with one form of blood parasites or another or combinations of the parasites. There was however no significant statistical  relationship (p>0.05) between the number of cattle positive for M. bovis and the presence of haemoparasites among the examined cattle.Keywords: Mycoplasma bovis, cattle, ELISA, hemoparasitism, institutional farms, Nigeri

Seroprevalence of contagious bovine pleuropneumonia in Plateau state, North-central Nigeria

This survey was undertaken to establish the prevalence of contagious bovine pleuropneumonia (CBPP) in Plateau State, Nigeria by screening 528 cattle for Mycoplasma mycoides subspecies mycoides (Mmm) antibodies using competitive enzyme-linked immunosorbent assay (c-ELISA). Sera samples were collected from 6 randomly selected local government areas (LGAs) of the State over a 14-month period (May, 2013 – June, 2014). Results showed an overall CBPP seroprevalence of 14.39% for the State. Antibodies to Mmm were detected in all the LGAs sampled with prevalence ranging from 7.50% to 31.58%, indicating a significant association (P<0.05). Seasons (P<0.05, χ2=34.00) and sample collection points (P<0.05, χ2=8.848) were also significantly associated with the seroprevalence of CBPP. There was however, no significant association (P>0.05, χ2=0.47) between the sex of cattle and seroprevalence of CBPP. This study confirms that CBPP is widespread, and the findings could serve as a baseline for initiation of effective control programmes against the disease to improve cattle health and production in the State.Key words: Contagious bovine pleuropneumonia, seroprevalence, Plateau State
