Since 2009, Poland has had a TB-free status, although over the last seven years 12-34 cases of bovine TB have been recorded annually. In 2009-2012 the largest number of cattle infected with Mycobacterium bovis and Mycobacterium caprae were culled in Masovian Voivodeship. Likewise, the largest number of sources of this zoonosis were recorded in that voivodeship. The vicinity of farms where bTB was found indicated that it could have been transmitted between their herds. The aim of this study was to characterise the molecular patterns of bovine bacillus strains isolated from cattle in Masovian Voivodeship and the molecular relationships between them. The material for microbiological examination came from 38 cattle (Bos taurus) located in 7 counties of Masovian Voivodeship. These 38 strains of MTBC were further identified as M. bovis (24 isolates; 63%) and M. caprae (14 isolates; 37%). A two-step genotyping analysis of the 38 MTBC strains identified 24 molecular patterns, closely related phylogenetically, which were assigned to 8 clusters of 2-6 strains. Sources of transmission were identified in 8 out of 13 herds examined in the 7 counties of Masovian Voivodeship. The results of the genotyping analysis excluded the possibility of TB transmission between different herds in Masovian Voivodeship. It was proved, however, that TB had been transmitted between animals bred on one of the farms.

Introduction. Tuberculosis is an infectious disease of humans and animals caused by the organism of the Mycobacterium tuberculosis complex (MTBC). It is one of the most widespread infectious diseases occurring in zoos. Taking into account the number of visitors to these sites, tuberculosis remains a major public health problem. Material and methods. The study material consisted of lymph nodes, and internal organs collected post mortem from five zoo animals suspected of tuberculosis: antelope, two tapirs, alpaca and bison. The animals came from the zoos in Gdańsk, Wrocław and Chorzów. The microbiological analysis of 5 MTBC strains was performed to determine the molecular relationships among them. Results. Five strains were isolated in the microbiological examination, 3 of which were identified as Mycobacterium bovis and 2 − as Mycobacterium caprae. 3 spoligotypes, i.e. SB1912, SB0856, SB2416, were obtained by spoligotyping. To confirm the transmission of tuberculosis in the studied animal population, the MIRU-VNTR method was applied. The unique patterns were assigned to 3 strains and the other 2 of the same pattern were assigned to one cluster, which would indicate the transmission of tuberculosis among animals. Conclusions. The obtained results exclude the transmission of tuberculosis between zoos.
