Spectrum of uropathogens and their susceptibility to antimicrobials in pregnant women: a retrospective analysis of 5-year hospital data.

OBJECTIVE

Urinary tract infections (UTI) are common during pregnancy. Identification of antimicrobial susceptibility patterns of microorganisms in pregnant women is important to select the most appropriate antimicrobial. We assessed common uropathogens in pregnant women with UTI and antimicrobial susceptibility, to guide empirical antibiotic selection.

METHODS

In this retrospective study, we analyzed mid-stream urine culture and antibiotic susceptibility data from pregnant women who attended Jordan University Hospital during 2014 to 2018. Data were collected from patients' charts and urine cultures, and sensitivity results were extracted from the laboratory electronic system. We calculated descriptive statistics and determined correlations among pathogens and antibiotics.

RESULTS

We examined 612 positive urine cultures from 559 pregnant women, including 163 (29.2%) inpatients. (29.4%) was the most frequently identified microorganism, followed by coagulase-negative staphylococci (CoNS) (21.6%). All bacterial isolates were sensitive to aztreonam, chloramphenicol, fosfomycin, ofloxacin, pefloxacin, piperacillin, and colistin sulfate; 87.5% were sensitive to amikacin. Only 15.79%, 18.93%, and 17.91% were sensitive to oxacillin, nalidixic acid, and erythromycin, respectively.

CONCLUSION

and CoNS were the most commonly identified microorganisms in this study. We found increased antibiotic resistance in species. The chosen antimicrobial therapy in pregnancy should be determined by sensitivity/resistance and fetomaternal safety.
