The prevalence and distribution of leptospiral titres in cattle and pigs in Queensland.
Serological test results for leptospiral species on serums from cattle and pigs performed by the diagnostic laboratories of the Queensland Department of Primary Industries from July 1973 to June 1976 were used to determine the prevalence and geographical distribution of 3 leptospiral serotypes in Queensland. There was a higher prevalence of antibodies to L. hardjo than to L. pomona in cattle, whereas in pigs the prevalence of antibodies to L. pomona was much higher than that for L. tarassovi or L. hardjo. Feral pigs had a particularly high prevalence of L. pomona antibodies. There is a different geographical distribution of antibodies to L. pomona and L. hardjo. L. hardjo antibodies appear to be fairly uniformly distributed but there is a higher prevalence of L. pomona antibodies in low rainfall areas. This relationship was shown to be significantly correlated.
