Summary of "Dependence of biofilm-forming ability on the antibiotic sensitivity of Pseudomonas aeruginosa clinical strains isolated from patients with chronic osteomyelitis."

Due to the spreading highly resistant strains among clinically significant P. aeruginosa clones, it becomes necessary to prescribe antibiotics not only taking into account the knowledge of sensitivity spectrum of a particular isolate but the data of microorganism biofilm activity as well. To study the dependence of biofilm-forming ability on the sensitivity to antibacterial preparations of P. aeruginosa clinical strains, isolated from patients with chronic osteomyelitis. 36 patients above 18 with chronic osteomyelitis of long tubular bones who were treated in the center of purulent osteology took part in the experiment. Object of the study - material isolated from wounds, fistulas, as well as from inflammatory foci. The sensitivity of isolated microorganisms to 10 antibiotics was analyzed: Piperacillin/Tazobactam, Imipenem, Meropenem, Aztreonam, Amikacin, Ciprofloxacin, Ceftriaxone, Ceftazidime, Cefotaxime, Cefepime. High- and medium-adhesive strains accounted for 86,1 % among P. aeruginosa clinical isolates, obtained from the wounds of patients with chronic osteomyelitis of long tubular bones. Highly adhesive strains are resistant to a wide range of antibacterial preparations used clinically. Penicillins were the most effective preparations when analyzing antibioticograms obtained for highly adhesive strains, for medium adhesive strains - penicillins, aminoglycosides and carbapenems, for low adhesive ones - aminoglycosides, penicillins, carbapenems, monobactams, quinolones. P. aeruginosa multi-resistance is a serious problem in the treatment of patients with chronic osteomyelitis. Spreading antibiotic-resistant strains of P. aeruginosa is associated with the presence of bacteria in the biofilm. Since adhesion is the first step in the biofilm formation, it is important to identify strains having high adhesive ability timely.

Medical and Biotech [MESH] Definitions

Antibiotic pigment produced by Pseudomonas aeruginosa.

A COAGULASE-negative species of STAPHYLOCOCCUS found on the skin and MUCOUS MEMBRANE of warm-blooded animals. Similar to STAPHYLOCOCCUS EPIDERMIDIS and STAPHYLOCOCCUS HAEMOLYTICUS, it is a nosocomial pathogen in NICU settings. Subspecies include generally antibiotic susceptible and BIOFILM negative capitis and antibiotic resistant and biofilm positive urealyticus isolates.

A species of gram-negative, aerobic, rod-shaped bacteria commonly isolated from clinical specimens (wound, burn, and urinary tract infections). It is also found widely distributed in soil and water. P. aeruginosa is a major agent of nosocomial infection.

Bacteriocins elaborated by mutant strains of Pseudomonas aeruginosa. They are protein or protein-lipopolysaccharide complexes lethal to other strains of the same or related species.

A topically used antibiotic from a strain of Pseudomonas fluorescens. It has shown excellent activity against gram-positive staphylococci and streptococci. The antibiotic is used primarily for the treatment of primary and secondary skin disorders, nasal infections, and wound healing.
