OBJECTIVES To analyse the sequence diversity of the tetracycline resistance gene tet(M) and its location on mobile elements in Enterococcus faecium and Enterococcus faecalis from humans, pigs and poultry in Denmark. METHODS A total of 76 isolates were screened for Tn916/Tn1545-like and Tn5397-like transposons using PCR. tet(M) was sequenced in 15 of the isolates and compared with tet(M) seque...

BACKGROUND Infections caused by antimicrobial-resistant bacteria are associated with increased mortality and health care costs. Enterococci have been recognized as a clinically important pathogen in hospitalized patients. Vancomycin-resistant enterococci (VRE) infections cause significant morbidity and mortality among patients undergoing transplantation. OBJECTIVE To identify epidemiology of ...

Possible cross-transmission of hospital-associated enterococci between human patients, medical staff, and hospital environments has been extensively studied. However, limited information is available for veterinary hospital-associated Enterococcus isolates. This study investigated the possibility of cross-transmission of antibiotic-resistant enterococci between dog patients, their owners, veter...

Emergence of vancomycin-resistant Enterococci (VRE) that first appeared on the stage about three decades ago is now a major concern worldwide as it has globally reached every continent. Our aim was to simply undertake a multinational study to delineate the resistance and virulence genes of clinical isolates of VRE isolates from the Caribbean. We employed both conventional (standard microbiologi...

Enterococcus spp. from two poultry farms and proximate surface and ground water sites in an area of intensive poultry production were tested for resistance to 16 clinical antibiotics. Resistance patterns were compared to assess trends and possible correlations for specific antimicrobials and levels of resistance. Enterococci were detected at all 12 surface water sites and three of 28 ground wat...

INTRODUCTION Enterococci are opportunistic pathogens which represent one of the leading agents of nosocomial infections, especially urinary tract infections (UTI) in hospitalized patients. The aim of the present study was to determine the resistance pattern and the type of resistance genes in vancomycin-resistant Enterococcus isolated from an educational hospital in Iran. MATERIALS AND METHOD...

We investigated the antibiotic susceptibility of glycopeptide-resistant enterococci (GRE). Seventy consecutive GRE were tested. Sixty-two isolates were identified as Enterococcus faecium (88.6%), and 8 (11.4%) as Enterococcus faecalis. All strains were susceptible to linezolid and daptomycin, while 17.1% (12/70) and 11.4% (8/70) were resistant to quinupristin/dalfopristin (QD) and tigecycline, ...

Treatment of asymptomatic bacteriuria and urinary tract infections in pregnancy can prevent adverse outcome for mother and child. However, antimicrobial resistance can impede effective chemotherapy. From April 1995 to March 1996, urine specimens from 5153 pregnant women in a rural area in northern Tanzania were inoculated on dip slides. Bacterial isolates from 101 positive dip slides were ident...

Vancomycin-resistant enterococci (VRE) may be spread within a hospital via the contaminated hands of the healthcare worker. Effective hand disinfectants are necessary to break chains of transmission. We determined the bactericidal activity of 1-propanol, chlorhexidine digluconate (0.5 and 4%). Sterillium (45% 2-propanol, 30% 1-propanol and 0.2% mecetronium etilsulphate), Skinsept F (70% 2-propa...

Sir, Linezolid is the first of a new class of antibiotics, the oxazolidinones, recently licensed for clinical use in Portugal (September 2001). This antibiotic has demonstrated good activity against Gram-positive organisms, including strains resistant to multiple antimicrobials, such as vancomycin-resistant enterococci (VRE). However, the emergence of enterococcal isolates resistant to linezoli...
