Abstract
Of 1193 Texas slaughterhouse cattle serum samples assayed for anti-leptospiral antibodies by microscopic agglutination testing, 262 (22%) reacted with serovar pomona and 179 (15%) with serovar hardjo. Of 300 urine samples tested for leptospiral DNA by a polymerase chain reaction assay, 106 (35%) were positive. The high prevalence of leptospiral infection of cattle represents potential threats to human health and agricultural economics.
