The analysis of periimplant infection agents showed a leading etiological role of staphylococci, accounting for 2/3 of all isolated microflora. Molecular genetic research revealed the presence of mecA gene in every third staphylococcus. The phenotype of methicillin-resistant staphylococci was found both in aureus and coagulase-negative strains. Among the Gram-negative bacteria the fermenting (Klebsiella oxitoca, Enterobacter cloacae) and non-fermentative bacillus (Pseudomonas aeruginosa, Acinetobacter baumanii) were separated (isolated). Two isolated enterobacteria strains produced extended-spectrum β-lactamases and were susceptible to carbapenems only. Acinetobacters (two strains of Acinetobacter baumanii in three isolated strains) were carriers of ОХА-40-like carbapenemase gene. Pseudomonas were sensitive to aminoglycosides, cephalosporins and carbapenems. Enterococci (3 strains) were susceptible to all antimicrobial drugs.
