Pseudomonas Aeruginosa as the Main Causative Agent of Osteomyelitis and its Susceptibility to Antibiotics

Surgical activity is increasing in the treatment of many types of fractures, the use of various metal structures, and the potential for infection with the development of osteomyelitis accordingly increases. The urgency of the problem is due to the fact that this disease is the most expensive medical problem, especially when it comes to prosthetics of large joints, with socially significant losses and the occurrence of disability in patients of working age, it requires long-term treatment. The aim of this study was to study one of the most complex pathogens of life-threatening infections due to its high virulence and ability to adapt to changing environmental conditions, in particular the action of antibacterial drugs and the study of its sensitivity to certain groups of antimicrobial drugs. The results of the study showed that over the three years of observation in 2017-2019, the average value of Pseudomonas aeruginosa in the amount of 10.8 % was established in the etiology of osteomyelitis. The revealed sensitivity of Pseudomonas aeruginosa is preserved to fluoroquinolone - levofloxanin, aminoglycosides-amikacin, gentamicin, carbapenems - meropenem, doripenem. All of the above drugs can be used as empirical therapy. During this period, a significant decrease in sensitivity was found, which reached in 2019 for cefepime - 51.9 %, pefloxacin - 55.8 %, ertapenem - 59.7 %. The success of the treatment of this pathology directly depends on the timely microbiological diagnosis and the choice of patient treatment tactics with the appointment of effective antibacterial therapy, with an adequate exposure of antibiotic.
