    Seroprevalence of Brucella abortus and B. canis in household dogs in southwestern
    (2011) Cadmus,S.I.B; Adesokan,H.K; Ajala,H.O; Odetokun,W.O; Perrett,L.L; Stack,J.A
    A preliminary serological study of 366 household dogs in Lagos and Ibadan, southwestern Nigeria, was carried out to determine antibodies due to exposure to Brucella abortus and B. canis, using the rose bengal test (RBT) and the rapid slide agglutination (RSA) test, respectively. Results showed that 5.46 % (20/366) and 0.27 % (1/366) of the dogs screened were seropositive to B. abortus and B. canis, respectively.Of all dogs, 36 had a history of being fed foetuses from cows and 11 (30.6 %) of these tested positive in the RBT. Our findings, although based on a limited sample size and a dearth of clinical details, revealed that dogs in Nigeria may be infected with Brucella spp. given the wide range of risk factors. Further studies are recommended to elucidate the epidemiology of brucellosis in dogs and its possible zoonotic consequences in the country.

    zoonotic risks and transmission of mycobacteria species from cows' milk and slaughtered cattle to man in ibadan:role of butchers
    (2008) Cadmus, S.I.B.; Adesokan,H.K.; Adepoju,A.F.; Otesile,E.B.
    To ascertain the zoonotic risks association with the handling,processing and consumption of milk and meat products in respect to bovine tuberculosis in ibadan. This study was conducted by simultaneous screening of 105 unpasteurised cows milk. samples and 587 slaughtered cattle some of which showed gross lesions suggestive of tuberculosis. samples from the milk and suspected tuberculosis lesions were cultured in lowenstein-jensen media while nitrate and niacin tests were carried out to classify the isolated mycobacteria species. prevalence rates of 5.7% and 4.3% were confirmed from the milk and cattle samples: screened respectively. based on the biochemical tests, three isolates of mycrobacterium tuberculosis, one of M. Bovis and one of M. africanum were identified from the milk samples: while six M. tuberculosis, fourteen M. bovis,two M. africanum and three unclassified mycrobacteria species were obtained from the tuberculous cattle. the unhygenic handling and processing of these animal products by butchers may lead to the zoonotic transmission of M. tuberculosis complex to the public and a source of occupational exposures to the butchers.
