Presence of the optrA Gene in Methicillin-Resistant Staphylococcus sciuri of Porcine Origin [PDF]

Antimicrobial Agents and Chemotherapy, 2016
ABSTRACT A total of 57 methicillin-resistant Staphylococcus aureus (MRSA) isolates and 475 methicillin-resistant coagulase-negative staphylococci (MRCoNS) collected from pigs in the Guangdong province of China in 2014 were investigated for the presence of the novel oxazolidinone-phenicol resistance gene

Emergence of optrA-mediated linezolid resistance in enterococci from France, 2006–16

Journal of Antimicrobial Chemotherapy, 2019
To describe the epidemiological trend of linezolid-resistant enterococci (LRE) collected in France from 2006 to 2016 and to extensively characterize LRE isolates.The National Reference Center for Enterococci (NRC-Enc) received enterococcal isolates suspected to be VRE and/or LRE from all French hospitals between 2006 and 2016.

Distribution of optrA and cfr in florfenicol-resistant Staphylococcus sciuri of pig origin

Veterinary Microbiology, 2017
A novel transferable oxazolidinone-phenicol resistance gene, optrA, which confers resistance to linezolid, the next-generation oxazolidinone tedizolid, and also to chloramphenicol and florfenicol, has been identified in enterococcal and staphylococcal species.

Detection of Genes Related to Linezolid Resistance (poxtA, cfr, and optrA) in Clinical Isolates of Enterococcus spp. from Humans: A First Report from Iran

Advanced Biomedical Research, 2023
Background: Enterococci may develop resistance to linezolid through chromosomal mutations that involve specific linezolid resistance genes, such as cfr, optrA, and poxtA.

Deleting or Keeping Outliers for Classifier Training? [PDF]

, 2014
This paper introduces two statistical outlier detection approaches by classes. Experiments on binary and multi-class classification problems reveal that the partial removal of outliers improves significantly one or two performance measures for C4.S ...

Occurrence of Florfenicol and Linezolid Resistance and Emergence of optrA Gene in Campylobacter coli Isolates from Tunisian Avian Farms. [PDF]

Int J Microbiol
Campylobacter species, especially C. coli and C. jejuni, have been associated with a range of human gastrointestinal diseases. During the last two decades, due to the irrational use of antibiotics in poultry farms, high rates of antimicrobial resistance have been globally reported in C. coli and C. jejuni isolates.

Rubber dam isolation for restorative treatment in dental patients [PDF]

, 2016
BACKGROUND: Successful restorations in dental patients depend largely on the effective control of moisture and microbes during the procedure. The rubber dam technique has been one of the most widely used isolation methods in dental restorative treatments.

Emergence of optrA-Mediated Linezolid-Nonsusceptible Enterococcus faecalis in a Tertiary Care Hospital

Annals of Laboratory Medicine, 2020
This study investigated resistance mechanisms and epidemiology of emerging linezolid-nonsusceptible Enterococcus faecalis (LNSEF) in a tertiary care hospital. LNSEF isolated from clinical samples were collected from November 2017 to June 2019. The isolates were investigated for linezolid resistance and the associated molecular mechanisms, including ...

Sentinel Surveillance Reveals Emerging Daptomycin-Resistant ST736 Enterococcus faecium and Multiple Mechanisms of Linezolid Resistance in Enterococci in the United States

Frontiers in Microbiology, 2022
Enterococcus faecalis and faecium with resistance to daptomycin and/or linezolid are emerging globally. We present the genomic characterization of daptomycin- and linezolid-resistant E. faecalis and E. faecium surveillance isolates from the United States,
