The prevalence of leptospirosis in abattoir workers in jos nigeria


, : The prevalence of leptospirosis in abattoir workers in jos nigeria. Israel Journal of Veterinary Medicine 44(1): 69-73

Serum samples from 112 abattoir workers were examined for leptospiral agglutinins by the microscopic agglutination test (MAT) method using twelve live leptospira antigens. Thirty-three (29.5%) of the workers were serologically positive for leptospirosis at a serum dilution of 1:100 and above. The prevalence of leptospiral antibodies among the abattoir workers in decreasing frequency were hardjo (8.9%), pyrogenes (6.3%), icterohaemorrhagiae (6.3%), pomona (4.5%), canicola (3.6%) and grippotyphosa (2.7%). Other serovars accounted for less than 4 per cent of the total reactors. A leptospira strain was isolated from the urine sample collected from one of the butchers with a leptospiral antibody titre of 1:1400. Poor abattoir practice as well as improper handling of the infected animal organs and tissues were probably responsible for the high prevalence of leptospiral agglutinins among the workers investigated.
