Local antimicrobial susceptibility surveys are crucial for optimal empirical therapy guidelines and for aiding in antibiotic stewardship and treatment decisions. For many laboratories, a comprehensive overview of local antimicrobial susceptibility patterns of anaerobic bacteria is still lacking due to the long incubation time and effort involved. The present study investigates the antimicrobial susceptibility patterns and related clinical and demographic data of 2856 clinical isolates of anaerobic bacteria that were submitted for analysis to the Institute for Medical Microbiology and Hygiene of the Freiburg University Medical Center (a tertiary university medical center in Southern Germany) between 2015 and 2019. Antimicrobial susceptibility testing has been carried out according to the European Committee on Antimicrobial Susceptibility Testing (EUCAST) guideline. Minimum inhibitory concentration (MIC)50 and MIC90 for penicillin, metronidazole, moxifloxacin, and clindamycin were established for Gram-positive anaerobes and for ampicillin-sulbactam, meropenem, metronidazole, moxifloxacin, and clindamycin for Gram-negative anaerobes. The distribution of MIC-values for various antibiotics against anaerobic bacteria was also established, especially for those having no specific breakpoints according to EUCAST guidelines. Most clinically relevant anaerobic bacteria originated from general surgery, neurological, and orthopedic wards. A high proportion of isolates were resistant to moxifloxacin and clindamycin indicating the importance of their susceptibility testing before administration. Based on our study metronidazole and other β-lactam/β-lactamase inhibitor combinations such as ampicillin-sulbactam remain suitable for empirical treatment of infections with anaerobic bacteria.

Um estudo retrospectivo foi realizado com gestantes atendidas no Hospital Universitário de Londrina, Paraná, Brasil para determinar a prevalência de colonização vaginal-retal por Estreptococos do Grupo B (EGB) e o perfil de sensibilidade de EGB aos antimicrobianos utilizados para a antibioticoterapia profilática intraparto. Swabs vaginais-retais foram coletados de 2.901 mulheres entre a 35ª e 37ª semana de gestação. Destes, 528 (18,2%) apresentaram cultura positiva para EGB, e 0,4%, 10,2% e 10% dos isolados foram resistentes à penicilina, eritromicina e clindamicina, respectivamente. Estes resultados destacam a importância de vigilância contínua da colonização por EGB em gestantes para a prevenção de infecções em neonatos por EGB.

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