Veterinarni Medicina 43, 1998, 221-231

As of 10 October, 1968, bovine tuberculosis in cattle was eliminated in the Czech Republic within the framework of national elimination programme (1959 to 1968). The postelimination period (1969 to 1996) was typical by Vanishing of infection source reservoirs during several following years. Currently only sporadic cases are recorded. in the period of the years 1969 to 1996 bovine tuberculosis was newly detected in 369 farms of cattle (42 small farms with up to 9 dairy cows and 327 larger farms with more than 10 dairy cows). No occurrence of bovine tuberculosis was found in the years 1981, 1987 to 1990, 1993 and 1996. In the remaining years of the period between 1980 and 1996, there were always maximum 3 outbreaks of bovine tuberculosis in cattle detected per year. The rate of infected animals out of the total size of herds was very low and did not exceed 5 to 10% of animals. In the years 1970 to 1996 the infection with Mycobacterium bovis was also diagnosed in total of 119 animals (zoological gardens, wild animals, small farms) and in 10 samples of milk. In the sense of OIE definition (International Animal Health Code) the territory of the Czech Republic. is free from bovine tuberculosis (prevalence up to 0.2% of infected herds of cattle). In human population in the years 1969 to 1996 the spread of M. tuberculosis was recorded in totally 77 739 newly infected persons and the infection with M. bovis in 476 patients. In 1981 to 1996 the prevalence of bovine tuberculosis ranged in absolute figures between 4 and 20 patients of higher age groups - above 50 years (0.04 to 0.20 per 100 000 inhabitants). The incidence of this disease in absolute figures was 3 to 19 patients (0.05 to 0.18 per 100 000 inhabitants)
