Microbiological monitoring of antibiotic resistance of strains of Streptococcus agalactiae among pregnant women

Group B Streptococcus (GBS) is the causative agent in 2–7% of all urinary tract infections (UTI), including asymptomatic bacteriuria (AB), cystitis, and pyelonephritis. We used bacteriological quantitative method sowing urine samples pregnant women on Columbia agar with 5% lamb blood), Strepto chromogenic Todd Hewitt broth, identification GBS strains determination sensitivity to bacitracin, hippurate hydrolysis test CAMP test. Susceptibility antimicrobial drugs was determined by disk-diffusion according recommendations European Committee Antimicrobial Testing. For period 2021, out 3,356 women, there were 149 investigated biomaterial a positive result for (resultancy – 4.4%). It established that among studied contingent, 41 isolated first trimester pregnancy (27.5%), second 59 (39.5%), third 49 (33.0%). GBS, 38 (25.0%) resistant norfloxacin, 45 (30.0%) erythromycin, (28.0%) clindamycin,125 (84.0%) tetracycline, 20 (13.0%) levofloxacin, 3 (2.0%) nitrofurantoin. All agalactiae found be sensitive benzylpenicillin. The number SGB identified from 47 strains. at least three groups antibacterial drugs, except beta-lactams. results scientific research will allow us obtain dynamic data antibiotic resistance order study rate development this microorganism. In future, can scientists when reviewing protocols treatment women.
