“…Quinones et al [10] reported that tetracycline resistance rates in E. faecalis and E. faecium were 78.6 and 90%, respectively, similar to our findings. It has generally been reported that nitrofurantoin resistance rate is low [10]. We found that the susceptibility of E. faecalis to nitrofurantoin was 98.5%, and it was 60.6% for E. faecium.…”

“…The Enterococcus genus has many species of which E. faecalis and E. faecium still account for the majority of human infections (9)(10)(11)(12). Recent studies have shown a significant increase in the isolation of more unusual species such as E. durans, E. hirae, E. gallinarum and E. casseliflavus from clinical samples (12)(13)(14).…”

Background: Enterococci are a natural part of the genito-intestinal and gastrointestinal normal flora in humans and are widely distributed in the environment and are one of the most important causes of nosocomial infections. Objectives: The aim of this study was to identify Enterococcus spp. from vaginal samples of pregnant women and measure their antibiotic resistance patterns. Methods: This descriptive study was performed on 602 strains. Vaginal swabs were cultured for Enterococcus spp. from pregnant women at 35 -37 weeks of pregnancy in Kerman city, Iran, during April 2013 to March 2014 or in labor samples transported to the laboratory using Amies transport medium. Swabs were cultivated in Todd Hewitt broth medium and subsequently plated on blood agar plates containing gentamicin and nalidixic acid. Antimicrobial susceptibility testing was performed for enterococci by disk diffusion and minimum inhibitory concentrations (MIC). Results: Vaginal colonization of Enterococcus genus was 8.14%. Parameters of age, parity, history of abortion, history of ruptured membranes, vaginal discharge and other vaginal signs (itching and so on) had no influence on vaginal colonization of Enterococcus spp. The predominant species were respectively E. faecalis 89.8%, E. faecium 6.1% and other Enterococcus spp. 4.1%. All samples were sus-

Urban and agricultural soils in Southern California are a reservoir of carbapenem‐resistant bacteria

Carbapenems are last‐resort β‐lactam antibiotics used in healthcare facilities to treat multidrug‐resistant infections. Thus, most studies on identifying and characterizing carbapenem‐resistant bacteria (CRB) have focused on clinical settings. Relatively, little is still known about the distribution and characteristics of CRBs in the environment, and the role of soil as a potential reservoir of CRB in the United States remains unknown. Here, we have surveyed 11 soil samples from 9 different urban or agricultural locations in the Los Angeles–Southern California area to determine the prevalence and characteristics of CRB in these soils. All samples tested contained CRB with a frequency of <10 to 1.3 × 104 cfu per gram of soil, with most agricultural soil samples having a much higher relative frequency of CRB than urban soil samples. Identification and characterization of 40 CRB from these soil samples revealed that most of them were members of the genera Cupriavidus, Pseudomonas, and Stenotrophomonas. Other less prevalent genera identified among our isolated CRB, especially from agricultural soils, included the genera Enterococcus, Bradyrhizobium, Achromobacter, and Planomicrobium. Interestingly, all of these carbapenem‐resistant isolates were also intermediate or resistant to at least 1 noncarbapenem antibiotic. Further characterization of our isolated CRB revealed that 11 Stenotrophomonas, 3 Pseudomonas, 1 Enterococcus, and 1 Bradyrhizobium isolates were carbapenemase producers. Our findings show for the first time that both urban and agricultural soils in Southern California are an underappreciated reservoir of bacteria resistant to carbapenems and other antibiotics, including carbapenemase‐producing CRB.
