The objectives of the present study were to verify the seroprevalence of anti-Leptospira spp. antibodies, identify the most frequent serovars and the risk factors associated with the infection in Uberlândia, Minas Gerais, Brazil. A total of 334 ovines blood samples were collected in 12 farms from Uberlândia municipality to be evaluated by means the Microscopic Agglutination Test (MAT) against 2...

Seroprevalence of Leptospira spp. in cattle is unknown in Uganda. The aim of this study was to estimate the seroprevalence of L. interrogans Icterohaemorrhagiae, Pomona, L. kirschneri Butembo, Grippotyphosa, L. borgpetersenii Nigeria, Hardjo, Wolfii, and Kenya and an overall seroprevalence in cattle from Kole and Mbale districts. Two hundred-seventy five bovine sera from 130 small holder farms ...

** Ministry of Agriculture, Department of Quality, Veterinary Services, Central Laboratory for Veterinary Research, B.P. 67, 94703 Maisons-Alfort Cedex, France. Summary : Leptospirosis occurs, at least in its inapparent form, in the majority of European countries. Clinical incidence is generally low. However, the disease has created problems in pigs in Central Europe and in cattle infected by s...

Abstract: The presence of dogs has been identified as a risk factor for human Leptospirosis. The aim of this study was the survey of the current state of leptospiral infection in dogs in Ahvaz. Sera from 100 rural dogs of villages around Ahvaz and 49 urban dogs referred to veterinary hospital of shahid Chamran University were detected for antibodies against serovars canicola, icterohaemorrhagia...

Leptospira interrogans serovar icterohaemorrhagiae RGA (RGA), live or heated at 56 degrees C for 15 min or treated with Formalin, was injected into rabbits to prepare hyperimmune serum. The pathogens L. interrogans serovars icterohaemorrhagiae RGA, icterohaemorrhagiae 1, canicola Moulton, grippotyphosa Andaman, hardjo Hardjoprajitno, and pomona Pomona and the nonpathogen Leptospina biflexa sero...

White-tailed deer (Odocoileus virginianus) are commonly exposed to disease agents that affect livestock but environmental factors that predispose deer to exposure are unknown for many pathogens. We trapped deer during winter months on two study areas (Northern Forest and Eastern Farmland) in Wisconsin from 2010 to 2013. Deer were tested for exposure to six serovars of Leptospira interrogans (gr...

A serologic, bacteriologic, and histopathologic examination for leptospires was carried out on 89 armadillos (Chaetophractus villosus) from Argentina. Forty-seven per cent of the serum samples yielded positive results when tested by microscopic-agglutination. Predominant agglutination reactions were to the Hebdomadis and Bataviae serogroups. A total of 15 Leptospira isolations (from 16.8 per ce...

Leptospirosis is a bacterial zoonotic disease, which can induce hepatic lesions. Photosensitization (PS)maybe is the result of accumulation of photodynamic agents in unpigmented area of the skin exposed tosunlight which occurred due to hepatic lesions. An outbreak of leptospirosis was occurred in a dairy cattleherd complex with 760 dairy milking cows in March (1990). Totally, 412 cows (54.21%) ...
