    The use of the milk ring tet and rose Bengal test in brucellosis control and eradication in Nigeria.
    (2008) Cadmus, S.I.B; Adesokan,H.K; Adepoju,A.F; stack, J.
    In this study, milk and blood samples collected simultaneously from 532 trade cows to be slaughtered at Bodija abattoir, Ibadan (southwestern, Nigeria) were examined for antibodies to Brucella using the milk ring test (MRT) and the rose bengal test (RBT). Overall, 18.61% of the milk samples were positive according to the MRT, while 9.77 % of the serum samples were positive according to the RBT. The difference was highly significant (Chi-square value 16.33; P<0.05); only 32 (6.02 %) of the samples were positive for both tests. The Red Bororo breed of cattle and the White Fulani had the highest positive rates, namely 20.93 % and 11.69%for the MRT and RBT respectively .No conclusion can be drawn about sensitivity because we do not know the true status of the animals tested. It is, however, obvious that although the MRT and RBT are 1st-line screening tests for brucellosis in cows in some countries, their lack of specificity is of concern. Therefore, the requirement for other confirmatory tests that are more specific should be considered for control and eradication of the disease, especially in Nigeria.

    Serological survey of brucellosis in livestock animals and workers in Ibadan, Nigeria
    (2006) Cadmus S. I. B.; Ijagbone I. F.; Oputa H. E.; Adesokan H. K.; Stack J. A.
    A serological survey of brucellosis in livestock animals and workers was conducted in Ibadan, Southwestern Nigeria between May and August 2004. A total of 1,210 cattle, 54 sheep, 496 goats, 200 pigs and 21 humans (i.e. butchers and herdsmen) were screened using the Rose Bengal test (RBT).From the results, prevalence in trade cattle was 5.82% while 0.86% was recorded in goats. None of the sheep and pigs was positive to the test. Out of the 11 samples taken from butchers, seven were positive and none of the ten herdsmen were sero-positive. This gives an infection rate of 63.3% in the butchers; and a combined infection rate of 31.82% in humans. This shows that brucellosis is still a major zoonosis in Nigeria; other public health implications are discussed.
