Abstract
Brucellosis is an alarming neglected zoonotic disease prevalent in most of the developing countries characterised by abortion, weak neonate, retention of foetal membrane, infertility, intra uterine infection both in animals and humans. The present study was carried out to know the prevalence and occupational risk of brucellosis in goats and persons engaged in goat farming and also compare the tests in terms of sensitivity and specificity. A total of 100 goat serum samples were screened by RBPT, STAT and I-ELISA to detect anti Brucella antibodies and overall prevalence recorded 4, 6 and 9 per cent by respective tests. Prevalence was higher in above 4 years (25%) age group followed by 2-4 years (10.5%) and lowest in 1-2 years (2.9%) in goats. Does were most vulnerable shown (10.3%) than bucks by I-ELISA. Goats had history of abortion found more positive (p<0.001) than no abortion history. The sensitivity and specificity of RBPT and STAT calculated as 44.4, 55.6 per cent and 100, 98.9 per cent, respectively considering I-ELISA gold standard. About 21 blood samples were collected from animal attendants, subjected to RBPT, STAT, 2-ME and IgG ELISA. In humans the overall prevalence was found to be 14.3, 4.8, 9.5 and 9.5 per cent respectively. However, none of the human samples shown positive by IgM ELISA. To conclude, above results indicates that I-ELISA is highly sensitive and better diagnostic tool compared to other tests in diagnosis of caprine brucellosis. Lack of awareness and unhygienic practices by animal health workers increase the risk of acquiring the disease.
