[Algorithm of identification of atypical variants of Staphylococci, pathogens of chronic pyo-inflammatory processes in humans].

Staphylococcal pathogens of chronic relapsing infections, such as cystic pneumosclerosis and osteomyelitis are characterized by atypical morphology of the colonies (atypical variants of staphylococci) and present a subpopulation in clinically significant staphylococci. Since the loss of some phenotypic characteristics important for the genus Staphylococcus due to mutations, identification of such staphylococcal variants is difficult and sometimes impossible. An algorithm of identification of atypical variants of S.

[Characteristics of atypical forms of staphylococci (SCVs) isolated from patients with osteomyelitis].

Small-colony variants (SCVs), isolated from a population of the parental strains of Staphylococcus aureus, S. haemolyticus and S. epidermidis lost a number of features typical of the species and genus and were characterized by delayed growth, altered colony morphology, lack of pigmentation and changed carbohydrate consumption.

[Effect of biological fluids of the body on antimicrobial activity of ethonium-modified suture material].

Ethonium in solution and on the surface of surgical threads displays different antistaphylococcal activity in the presence of biological fluids: under the influence of bile, it decreases essentially, blood serum--decreases to a less degree, urine doesn't change it. A conclusion is made that for optimal use of the ethonium and surgical threads modified with ethonium it is necessary to take into account the location of a pathological focus.
