Background: This study aimed to characterize recent Mycobacterium bovis/M. caprae isolates from Bulgaria by whole-genome sequencing (WGS) to gain a first insight into their molecular diversity, transmission, and position within the global phylogeography of this important zoonotic species.
Results: The isolates were obtained from cattle in diverse locations of Bulgaria in 2015-2020 and were identified by microbiological and PCR assays.

The susceptibility of dogs to infection with Mycobacterium tuberculosis was studied through different ways of experimental infection. The examination shows, that in most cases the disease runs subclinically with pathological changes localized mainly in the lungs, lymph nodes, small intestines, liver, kidneys and spleen. Histological findings demonstrate granulomatous inflammation with caseosation and predominance of epitheloide macrophages and single lymphocytes.

Hirota's method was employed to ascertain that resistance to penicillin, erythromycin, neomycin, and kanamycin was governed by plasmids. It was found at the same time that, fairly often, with the elimination of some of the resistant markers the virulence of the strain variants also dropped.
