background and objectives: resistance to macrolide can be mediated by erm and msra genes in staphylococcus aureus . there are the evidences that show erm genes may be causative agent of inducible or constitutive resistance. the aim of this study was to investigate the incidence of inducible clindamycin resistance and determine the most frequency of erm and msr a genes among s. aureus isolates. ...
Estrogen receptor methylation (ERM) is a frequent molecular alteration in adult acute myeloid leukemia (AML). In this study, we sought to determine the clinical characteristics and prognostic significance of ERM in AML. ERM was determined for 268 patients who had leukemic blasts available for molecular analysis. ERM was measured by Southern blot analysis, and results were obtained for 261 patie...
ERM (ezrin-radixin-moesin) proteins mediate linkage of actin cytoskeleton to plasma membrane in many cells. ERM activity is regulated in part by phosphorylation at a C-terminal threonine, but the identity of ERM kinases is unknown in lymphocytes and incompletely defined in other mammalian cells. Our studies show that lymphocyte-oriented kinase (LOK) is an ERM kinase in vitro and in vivo. Mass s...
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.
مقدمه: استرپتوکوکوس آگالاکتیه (gbs یا group b streptococcus) باکتری است که به طور معمول در واژن، مجاری ادراری و دستگاه گوارش وجود دارد. کلونیزه شدن مادر با gbs تهدید کننده ی نوزاد به عفونت های اکتسابی از قبیل مننژیت، باکتریمی و پنومونی می باشد. مطالعه ی حاضر با هدف تعیین مقاومت استرپتوکوکوس آگالاکتیه به آنتی بیوتیک های انتخابی و تشخیص ژن های مقاوم به اریترومایسین از نمونه های جدا شده از زنان حا...
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...
