Macrolide resistance in 156 consecutive group B streptococcal isolates was investigated. Thirty-five isolates (22.4%) had inducible (80%) or constitutive (20%) erythromycin resistance. The genes responsible were erm(B), erm(A) subclass erm(TR), and erm(B) plus erm(TR) in 62.9, 2.9, and 8.6% of isolates, respectively. Nine isolates (25.7%) harbored neither mef nor detectable erm genes.

OBJECTIVES Increasing evidence indicates that ezrin/radixin/moesin (ERM) proteins may play a critical role in cell proliferation. This study examined the role of ERM proteins in proliferation of fibroblast-like synoviocytes (FLS) from patients with RA. METHODS Synovial tissues (STs) were obtained from 18 RA and 6 OA patients. The expression of ERM and its phosphorylated proteins in cultured F...

In staphylococci, inducible macrolide-lincosamide-streptogramin B (MLS(B)) resistance is conferred by the erm(C) or erm(A) gene. This phenotype is characterized by the erythromycin-clindamycin "D-zone" test. Although clindamycin appears active in vitro, exposure of MLS(B)-inducible Staphylococcus aureus to this antibiotic may result in the selection of clindamycin-resistant mutants, either in v...

A gene which mediates inducible resistance to macrolides, lincosamides, and streptogramin B antibiotics, designated erm(33), was detected on the Staphylococcus sciuri plasmid pSCFS1. Analysis of the erm(33) reading frame suggested that this gene was the product of a recombination between an erm(C) gene and an erm(A) gene. Such a recombination event is a novel observation for erm genes.

Enterprise risk management (ERM) has emerged as a new paradigm for managing the portfolio of risks that face organizations and delivers synergic value by exploiting natural hedges. Proponents of ERM claim that ERM is designed to enhance the shareholder value (SHV). Increasing numbers of researchers have studied the impact of ERM on a firms’ value (value creation) and found a positive correlatio...

disc testing was used to determine antibiotic susceptibility and erythromycin resistance phenotypes. DNA from test samples was prepared by both Qiagen extraction and rapid boiling. As the efficiencies of the two methods were comparable, the rapid boiling method was used throughout. Primers were as published for erm(A), erm(B), erm(C), mef(A/E) 5 and erm(TR). 4 Donor and acceptor probe-pairs wer...

PURPOSE To correlate the uveitic epiretinal membrane (ERM) features using spectral-domain optical coherence tomography (SD-OCT) with visual acuity (VA). METHODS Forty-one eyes of 32 patients were included in this retrospective study. SD-OCT was performed in all patients and data were collected at the time of ERM diagnosis and at the final visit. Both best corrected visual acuity (BCVA) and ER...

Purpose To compare the recurrence rate and need for reoperation after epiretinal membrane surgery with and without removal of the internal limiting membrane. Methods In this retrospective study, 125 patients operated for epiretinal membrane removal were evaluated, with a minimum 6-month follow-up. Removal of the epiretinal membrane (ERM) was performed in 78 patients, while 47 had removal of t...

This patient presented for surgery at the age of 32 years, 14 months after his initial complaint of metamorphopsia and visual loss in the right eye. Past tests demonstrated a whitish epiretinal membrane (ERM) with translucent stress lines over a thickened macula. Visual acuity was found on last presentation to be normal with minimal alteration on Amsler grid testing. A torn ERM was found in the...
