Shevchuk V. Tuberculosis young cattle (epizootology and diagnostics)

Object - tuberculosis of cattle. Purpose of researches consists in the study of epizootic features of tuberculosis to the sapling of cattle and development of the science-based system of vital diagnostics of infection at the calves of early age. Methods: epizootologic, clinical, allergic, postmortem, bacteriological and statistical. Scientific novelty of work consists in establishment in Ukraine: geographical unevenness and sentinel recurrence of development of epizootic process of tuberculosis of cattle - rise of tension in 1996-1999, decline in 2000-2002, complication in 2000-2005; positive correlative communication (r=0,6) in regions between the percent of economies which a reactive on a tuberculin cattle is registered in, and infectious total number of livestock; territorial parallelism (with the exception of Crimea) between morbidity of people by tuberculosis and percent of economies in regions where a reactive on a tuberculin cattle is registered. It is set, that M. tuberculosis in the herd of cows causes development of active epizootic process.The epizootic features of tuberculosis are first definite to the sapling of cattle: high receptivity to M. bovis calves from the first days of life; presence of two groups of sources of exciter of infection - cows and young animals of 16-daily and senior age; mainly alimentary way of transmission of exciter of infection; recurrence of development of epizootic process; presence of feed-back of activity of sun radiation and tension of epizootic situation; absence of influencing of natural-geographical factors on development of epizootic process.In a theory and experimentally it is led to, that by the functional sign of sources of exciter of tuberculosis of cattle, as motive forces of epizootic process, there is a binary type: patients with tuberculosis of cow actively affect an epizootic process both among adult total number of livestock, and among calves (alimentary way of infection); a sapling comes forward the source of exciter of infection both for young animals, and for cows, and calves to 2-lunar age have high receptivity to the exciter of tuberculosis and show the intensive reaction of hypersensibility of slow type.
