Mycobacterium bovis and Mycobacterium caprae are species that be-long to the Mycobacterium tuberculosis (CMT) complex, together with other species of va-rying clinical relevance, and are known to be the main causative agents of tuberculosis in animals and the primary causative agent of zoonotic tuberculosis. The aim of the study was to analyze the incidence indicators of Mycobacterium bovis and Mycobacterium caprae species in cattle from Vaslui County, Romania. The study included the analysis of data from 2015-2021, obtained as a result of microbiological examinations of various biological samples prelevated from cattle with suspected tuberculosis. With the excep-tion of 2020, there were animals with suspected tuberculosis from which 115 strains of Myco-bacterium sp. were isolated throughout the 2015-2020 period. All strains were serotyped and classified into two species: Mycobacterium bovis (5,21%) and Mycobacterium caprae (94,78%). Analysis of the dispersion over time of Mycobacterium species isolation showed that Mycobacterium bovis was identified sporadically (2016, 2017), while Mycobacterium caprae was isolated continuously, except in 2020, when a number of sanitary-veterinary services were interrupted due to the crisis situation caused by the pandemic COVID -19.
