Study of susceptibility of staphylococcosis and streptococcosis causative agents to medicinal preparations

The article gives consideration to the determination of the susceptibility of causative agents of staphylococcosis and streptococcosis to antibiotics. Long-term use of medicinal preparations, including antibiotics, leads to the emergence of generations of microorganisms that are resistant to causative agents of infectious diseases, and this is the reason for the decrease in the effectiveness of medical and preventive measures. Considering all this, the susceptibility degree of cultures of causative agents of staphylococcosis and streptococcosis to drugs such as enroline, colistin, gentamicin, tilazine, furazalidone and neomycin was studied. The susceptibility of Staphylococcus pyugenes cultures to enroline, gentamicin and colistin by 22.2%, and to furasilidone by 74.0%, and Streptococcus feccalus cultures by 38.0% to enolin, by 33.3% to gentamicin, by 19.0% to colistin and by 33.3% to furazalidone were investigated. On the basis of findings of investigations, the highest sensitivity of Staphylococcus pyugenes to furazalidone by 74.0% was revealed. And from the preparations we studied, it was found that Streptococcus feccalus is susceptible to enroline by 38.0%.
