[Territorial dissemination of antibodies against leptospirae at individual farms throughout a district, detected on the basis of serological testing of slaughter cattle and pigs].
The serological reaction of microagglutination-lysis (RMAL) was performed to examine 4995 head of slaughter cattle and 8211 slaughter pigs for the presence of antibodies to leptospirae. The animals came from 33 farms of the Strakonice district. Antibodies to leptospirae were found in slaughter cattle from 25 (75.75%) farms and in slaughter pigs from 24 (72.72%) farms. As suggested by the examination, the antibodies to leptospirae occur in animals throughout the territory of the district, irrespective of the nature of the landscape. The occurrence of the above-mentioned antibodies on farms occurred within the range from 0.52% to 8.33% in slaughter cattle and from 0.32% to 8.10% in slaughter pigs; only rarely did it exceed 9.0%. The most frequent reactions were those with the leptospirae of the L. grippotyphosa serovar.
