Study of the mycobactericidal and tuberculocidal effects of the new biocidal composition
Abstract
Tuberculosis, as a zooanthroponotic disease, in many countries of the world and the Russian Federation to this day remains one of the most difficult problems of infectious pathology, while against tuberculosis and mycobacteriosis there are no sufficiently effective means of immunoprophylaxis and immunotherapy.
Objects of the external environment in farms unfavorable for tuberculosis are contaminated with both pathogenic and atypical mycobacteria, the presence of waxes, mycolic acids and polysaccharides in their cell wall determines their resistance to many physical and chemical factors, mycobacteria are resistant to many acids, alkalis, alcohols, and not sensitive to quaternary ammonium compounds, which are present in many disinfectants.
The purpose of our research was to study the disinfecting effect of the new biocidal composition against various types of mycobacteria.
As a new drug, a composition was used, which is a complex of chemical substances, consisting of detergents and active substances with a biocidal effect, a component from the group of oxidizing agents was introduced into the chemical formula of the drug, which has a high bactericidal effect and nonionic surfactants that exhibit good emulsifying properties, that is, it promotes mixing of substances that are immiscible under normal conditions and at the same time are not highly toxic compounds, an antifreeze component was added to reduce the corrosive effect.
Reference strains of atypical (M. phlei, M. scrofulaceum) and typical M. bovis pcs 14. The analysis of the results obtained showed that both typical and atypical cultures of mycobacteria are highly sensitive to a new complex biocide in comparison with another traditionally used drug, which in the concentration and exposure stated in the instructions for its use did not have either mycobactericidal or tuberculocidal effects.
