In 44 isolated cultures of Gram-negative bacteria, besides commonly known pathogenicity factors, their adhesive activity towards the cells of the buccal epithelium and their interrelations with the representatives of normal microflora which determine natural resistance to colonization have been studied. The artificial adhesion of target cells is accompanied(More)
As the results of the quantitative study of Streptococcus salivarius adhering to buccal epithelial cells, three levels of their natural colonization were established: low (less than 20 bacteria per epithelial cell), medium (20-50 bacteria), and high (more than 50 bacteria). The characteristics of natural colonization by S. salivarius inversely correlated(More)
Anthropometric investigations conducted have shown that 28.1% of the workers have excessive body mass. At the same time energy expenditure of workers at some departments and bays is within the range of 164 +/- 1.6-188.89 +/- 3.5 kcal/h. Natural resistance parameters (lysozyme activity, virus persistence) in the workers of the enterprise were lower than in(More)
The paper summaries authors' experience with lifetime and postmortem pulmonary changes in 223 victims with severe craniocerebral injury, as well as the data available in literature on this point. The investigations have shown that microcirculatory disorders make a great contribution to the development of pulmonary complications and revealed specific feature(More)
According to the data obtained by immunoblotting and other immunochemical techniques, the cell wall of Staphylococcus aureus, strain 209 P, contain proteinaceous receptors for plasminogen, plasmin and its complexes with alpha 2 glycoprotein and protein A, alpha 2 proteinase inhibitor, alpha 2 antiplasmin. Strains Cowan 1 and Wood 46 have no such receptors.(More)
The neutrophil-stimulating properties of 38 S. aureus strains and 32 S. epidermidis strains were studied in the reaction of luminol-mediated chemiluminescence. All S. aureus strains and 29 S. epidermidis strains were found to possess neutrophil-stimulating activity, the mean activity index for S. aureus being significantly higher. The stimulating activity(More)
