MICROBIOLOGICAL INVESTIGATION OF OUTPATIENTS'RESPIRATORY TRACT

We aimed to study bacterial structure and antibiotic susceptibility of main pathogens of outpatients' respiretory tract. Materials and methods, a prospective microbiological study of bacterial landscape and antibiotic susceptibility of strains isolated from 202 outpatients' respiratory tract based on Microbiology Laboratory of National Scientific Medical Research Center during September 2019 to October 2020. Identification of isolates were performed by Vitek-2 automated system. Results and discussion: during study period, 245 clinical samples were included, 282 strains were isolated; of them and the most frequently isolated microorganisms from throat swabs and sputum was Streptococcus mitis (51.7% and 33.6%), from nasal and ear swabs - Staphylococcus aureus (32.5% and 31.3% respectively). Conclusion, based on our results the most frequently pathogens of outpatients' respiratory tract were St mitis with high level of susceptibility to ceftriaxone (100%), co-trimoxazole (87.7%) and S. aureus with susceptibility to gentamicin and levofloxacin (100%) and co-trimoxazole (96.2%).
