conclusions the rate of imlsb in s. aureus isolates is relatively high in the northwest iran. since isolates with inducible resistance may mutate and change to constitutive resistance, to prevent clinical treatment failure, d-test should be performed along with routine antibiotic susceptibility tests. in this study, ermc gene was the predominant genetic determinant for the expression of mlsb re...

conclusions the results illustrated the diversity of antibacterial resistance and virulence gene profiles among different sccmec types of s. aureus. the increased prevalence of methicillin-resistant s. aureus isolates containing different toxin and antibiotic resistance genes is a serious threat for the hospitalized patients in the intensive care units. methods in this cross-sectional study tha...

Many pathogenic bacteria are adapted to live in aquatic habitats, which makes rivers possible sources and spread pathways of antibiotic resistance, since they usually receive effluents from wastewater treatment plants (WWTP), possibly containing residues also antibiotic-resistant bacteria. This study investigates different monitoring strategies identify the occurrence rivers. We analyzed presen...

Diseases caused by the zoonotic pathogen Streptococcus suis are an extensive economic problem as well animal welfare concern for global swine industry. Previous studies have evaluated genomic diversity and population structure of S. isolates, however, majority these utilized isolates obtained from countries other than U.S. This study applied whole genome sequencing cgMLST-based typing to evalua...

The application of animal manures to cropland is an important nutrient recycling strategy in many parts the world. Commonly, aggregated manure wastes contain chemical stressors including veterinary antimicrobials, heavy metals, and antimicrobial resistance genes (ARGs) that can stimulate development proliferation (AMR). While presence antimicrobials well-documented, co-occurrence other potentia...

OBJECTIVE Our objective was to assess the ability of real-time PCR to predict in vitro resistance in isolates of group B streptococcus (GBS). METHODS The first real-time PCR assays for the genes known to confer resistance to erythromycin and clindamycin in GBS were developed. Three hundred and forty clinical GBS isolates were assessed with these assays and compared with conventional disk diff...

A multicenter susceptibility surveillance (the S.A.U.C.E. project) including 2,721 Streptococcus pneumoniae, 3,174 Streptococcus pyogenes, and 2,645 Haemophilus influenzae consecutive isolates was carried out in 25 hospitals all over Spain from November 2001 to October 2002 to evaluate the current epidemiology of resistance of the main bacteria involved in community-acquired respiratory tract i...
