Microbiological aspects of peritonitis

Objective. To investigate pathogens in peritonitis. Materials and methods. In 2021 yr in Department of Surgery of Brovary Multidisciplinary Clinical Hospital were treated 360 patients with an acute peritonitis of various genesis: 186 (51.7%) women and 174 (48.3%) men. Results. In the patients 391 strains of microorganisms, which are optionally-anaerobic and aerobic of Gram-negative and Gram-positive pathogens were isolated: Escherichia coli – in 144 (36.8%), Streptococcus spp. – 52 (13.3%), Enterococcus faecalis – 47 (12.0%), Staphylococcus aureus – 37 (9.5%), Klebsiella pneumoniae – 31 (7.9%), Citrobacter – 25 (6.4%), Staphylococcus haemolyticus – 23 (5.9%), Pseudomonas aeruginosa – 14 (3.6%), Acinetobacter baumannii – 13 (3.3%), and Proteus mirabilis – 5 (1.3%) strains. Conclusion. Majority of microorganisms, isolated in patients, suffering peritonitis, was characterized by significant antibiotic resistance. Most frequently Escherichia coli was sowed – 36.8%. All strains of Escherichia coli isolated were resistant to vancomycine, clindamycine and linezolide.
