Conteúdo: | The epidemiology of leptospirosis in livestock is affected by a variety of environmntal factors. Studies on L. hardjo and L. pomona infection in extensively managed beef cattle in tropical Queensland were carried out using both abattoir-based pathology and serological field methods. Using sub-clinical interstitial nephritis as an index of recent leptospiral infection the incidence of disease was found to increase significantly in North Queensland after the peak period of rainfal which occurs during the summer monsoons (December to April). In herd studies in central Queensland which has a minor peak of winter rainfall a secondary increase of leptospirosis hardjo was also detected serologically which corresponded to the later stages of pregnancy. L. hardjo was significantly more prevalent (13%:p 0.01) than L. pomona (4.1%) in this area and also significantly commoner on properties with high water capacity soils (18%:p 0,05) than on low WHC soils (7.38%).
