“…In other studies, Enterococcusfaecalis was 85% (the most prevalent species), followed by E. faecium, which is the most common human pathogenic isolate (10,25,26). Enterococcus faecium has become increasingly prevalent in hospital-acquired infections (25).…”

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-

“…In a trial conducted on humans in 2005 by Kaçmaz and Aksoy (2005), 109 isolates obtained from a total of 264 urine, wound, blood, secretions and catheter samples were reported to be susceptible to vancomycin. In the current trial, 10 of 69 isolates (14.49%) of 238 faecal samples isolated from pigs demonstrated intermediate resistance to vamcomycin, while 7 isolates (10.14%) were regarded as resistant.…”

In this trial, Enterococcus strains were isolated from a total of 69 faecal samples obtained from 238 pigs (105 pigs < 6 months old and 133 > 6 months old) on three pig farms located in Istanbul and Tekirdag Provinces in the Marmara Region of Turkey in the summer season of 2003. Forty-seven of the isolates were determined as Enterococcus faecium (68%), 15 isolates as Enterococcus faecalis (21.7%), three isolates as Enterococcus gallinarum (4.3%) and one of each as Enterococcus hirae (1.4%), Enterococcus casseliflavus (1.4%), Enterococcus cecorum (1.4%) and Enterococcus sulfurens (1.4%). In addition, antimicrobial susceptibilites of isolates were assessed through the disk diffusion method. Among 47 E. faecium isolates, 44 were determined to be resistant to erythromycin, 38 to ciprofloxacine, and three isolates were resistant to vancomycin. All E. faecalis isolates were resistant to erythromycin (100%) and four were resistant to vancomycin (27%). Five E. faecium (11%) and five E. faecalis isolates (33%) were found to exhibit intermediate resistance to vancomycin. In this study, isolates obtained from pig faeces were determined to exhibit a high rate of antimicrobial resistance. This study is the first report on isolation and determination of antimicrobial resistance of Enterocci in Turkey.

Empirical antimicrobial therapy is usually started in febrile neutropenic patients without having culture results. The aim of this study was to help determine the policies of empirical antibiotic usage in febrile neutropenic children by detecting the antimicrobial susceptibility profile in this group of patients. In this study 811 blood cultures taken from neutropenic children hospitalized at the Department of Oncology of Gaziantep Children Hospital November 2007 and February 2010 were retrospectively evaluated. Blood cultures were routinely collected in aerobic and anaerobic media and incubated using the BACTEC system. Identification and antimicrobial susceptibility testing of the isolates to antimicrobial agents was performed using the Vitek2 Ò system according to the recommendations of the Clinical and Laboratory Standards Institute. Of 811 isolates analyzed, 128 (56.4%) were gram positive cocci, 43 (18.9%) were gram negative bacilli and fungi accounted for 56 (24.7%). The main isolated Gram-positive bacteria from blood were coagulase-negative staphylococcus (56.7%), followed by methicillin-resistant Staphylococcus aureus (14.1%). S. aureus and Streptococcus spp. were all susceptible to linezolid, vancomycin and teicoplanin. S aureus was still susceptible to few other antimicrobial agents such as tetracycline (82.4%), chloramphenicol (55.6%). Seven E. faecium, 7 E. fecalis and 1 E. hirae was isolated from blood cultures. Vancomycin resistance was detected in 6 out of 15 (40%) Enterococcus spp. isolates. Among gram-negative bacteria E. coli (30.2%) was followed by Klebsiella pneumoniae (20.9%) and Proteus spp. (18.6%). Imipenem (89.2%), meropenem (86.6%), chloramphenicol (88.9%), amicasin (82.4%) and fosfomycin (81.3%) showed highest susceptibility in vitro activity against all Gram-negative isolates. To know the antimicrobial susceptibility profile of the pathogens frequently isolated from febrile neutropenic children and to consider this profile before starting an empirical antibiotic therapy would help the clinics which have any role in the treatment of these patients to determine the empirical antibiotic usage policies.
