Seroprevalence of Leptospira Hardjo in the Irish suckler cattle population

BACKGROUND Prior to the present study, the seroprevalence of leptospirosis in Irish suckler herds was unknown. In this study, we describe the herd and animal-level prevalence of Leptospira Hardjo infection in the Irish suckler cattle population. For the purposes of the study, the 26 counties of the Republic of Ireland were divided into 6 regions from which a representative number of herds were ...

Risk factors and seroprevalence of Brucella spp. in cattle from Western Amazon, Brazil. RISK FACTORS AND SEROPREVALENCE OF BRUCELLA SPP. IN CATTLE FROM WESTERN AMAZON, BRAZIL

The seroprevalence of Brucella spp. and the possible associated risk factors were estimated for 2,109 adult cows in Monte Negro county, State of Rondônia, Brazil. A questionnaire was completed for each farm where cattle were sampled. Laboratory tests were Rose-Bengal Agglutination, Standard Tube agglutination, and Mercaptoethanol. The adjusted overall prevalence of Brucella spp. seropositive co...

Cattle serologically positive for Brucella abortus have antibodies to B. abortus Cu-Zn superoxide dismutase.

In this study, we demonstrated by a Cu-Zn superoxide dismutase-specific enzyme-linked immunoassay that cattle that are serologically positive for Brucella abortus have serum immunoglobulin G antibodies to B. abortus Cu-Zn superoxide dismutase. The specificity of the antibody reactivity was confirmed by Western blot (immunoblot) analysis with B. abortus salt-extractable proteins containing nativ...
