Bacterial suspensions of cultures (10(7) PFU) of pathogenic Staphylococcus, vulgar Proteus and pyocyanic bacterium are resistant to 2.9-46.87 mg per disc of iodopyron in 100% of cases. Sensitivity of 32 and 100% of cultures of pyocyanic bacteria (of 25 under study) being in the suspension (10(5) PFU) to 11.71 and 23.43-9.375 mg of idopyron, respectively, in a hole has been established. To determine sensitivity of pyocyanic bacteria to iodopyron it is suggested to use the procedure of adding of 11.71 mg of the preparation (water solution) to the holes in MPA.

Pseudomonas aeruginosa (PA) has emerged as a significant cause of Gram-negative infections, particularly in patients with impaired host defenses. It is one of the six ESKAPE pathogens that majorly cause severe nosocomial infections. In addition to biofilm formation, PA possesses various virulence factors.

Article Synopsis
  • The study focuses on the relationship between biofilm-forming ability and antibiotic resistance in Pseudomonas aeruginosa strains sourced from patients with chronic osteomyelitis.
  • High- and medium-adhesive strains dominate the clinical isolates and show significant resistance to commonly used antibiotics, complicating treatment options.
  • Identifying highly adhesive strains early is crucial since their presence in biofilms contributes to increased antibiotic resistance, making management of infections challenging.
