Macrolide and lincosamide resistance patterns in invasive and colonizing group B streptococcus isolated in Belgium
… For cMLS, the most common genotype was ermB (65%) (P <0,05) followed by ermTR (30%) and ermB+ermTR (5%). All iMLS isolates harbored an ermTR gene except 3 (2 with ermB, 1 with both ermB and ermTR); and all M phenotypes were positive for mefA/B gene. In Belgium, by year 2010, prevalence …

Fate and transport of antibiotic resistant bacteria and resistance genes in artificially drained agricultural fields receiving swine manure application
… known to confer macrolide antibiotic resistance (ermB, ermC, ermF and msrA) in soil and subsurface artificial drainage water. Manure concentrations for ermB, ermC and ermF were all >109 copy g-1. MsrA was not detected in manure, soil or water. The average enterococci concentration in manure was …

Recovery of Antibiotic Resistance Genes From Agricultural Runoff
… coli and enterococci) and two ARGs (sulI and ermB) were quantified in runoff from each of the constructed plots throughout the growing season. FIB and ARGs were recovered from all plots, including control plots indicating a background level within the soil. Additionally, only the effects of …

Abundance of Antibiotic Resistance Genes in Feces Following Prophylactic and Therapeutic Intramammary Antibiotic Infusion in Dairy Cattle
… DNA extraction. The abundance of ampC, blaCMY-2, ermB, sul1, tetO, tetW, integrase-specific gene int1, and 16S rRNA were quantified using quantitative polymerase chain reaction (qPCR). The genes ampC and blaCMY-2 encode resistance to ß-lactam antibiotics, ermB to macrolides, sul1 to sulfonamides, …

Metagenomic Analysis of Antibiotic Resistance Genes in the Fecal Microbiome Following Therapeutic and Prophylactic Antibiotic Administration in Dairy Cows
… Database (ARDB) via BLAST. Abundance of ampC, ermB, tetO, tetW, and 16S rRNA genes were determined using qPCR. All data were statistically analyzed with PROC GLIMMIX in SAS. Antibiotic treatment resulted in a shift in bacterial cell functions. Sequences associated with 'resistance to …

Multizentrische Studie zur Antibiotika-Resistenz von Streptococcus pneumoniae bei nicht-hospitalisierten Patienten mit Infektionen des Respirationstrakts in Deutschland, 1998-1999
… there were 74% of the genera recognized as ermB-resistance genotype positive. 20.5% belonged to the mefE types of resistance, respectively. Four strains showed no PCR product in repeated assays. A total of 415 strains were serotyped. In order of decreasing frequency, 19F, 23F, 6B and 6A were …

Determination of the occurrence, virulence genes, and antimicrobial resistance profiles of enterococcus faecalis and enterococcus faecium isolated from poultry of Chongwe, Lusaka, Kitwe, and Ndola districts, farmworkers from the Copperbelt province poultry farms and clinical specimens from Kitwe teaching hospital in Zambia.
… in E. faecium, it was aac(6′)-Ieaph(2″)-LA and ermB from Kitwe, and aac(6′)-Ie-aph(2″)-LA from Lusaka. In farmworkers, the frequently detected resistance gene in E. faecalis was tetL. In clinical specimens, the commonly detected resistant gene in E. faecalis was ermB, and in E. faecium, it was …

The Role of Bacteroides Conjugative Transposons in the Spread of Antibiotic Resistance Genes, And, The Role of recA in DNA Damage Repair in Deincoccus Radiodurans
… that carries a gene for erythromycin resistance (ermB). The same DNA sequence (100% identical) had been previously identified in the genome of Arcanobacterium pyogenes, a gram positive opportunistic pathogen that is a normal resident of the intestinal tract of cows. In addition, in order to better …

Excretion of Antibiotic Resistance Genes by Dairy Calves
… (tetC, tetG, tetO, tetW, and tetX), macrolides (ermB, ermF), and sulfonamides (sul1, sul2) classes of antibiotics along with the class I integron gene, intI1, were measured by quantitative polymerase chain reaction (qPCR). No tetC or intI was detected. There was no significant effect of …

Detection of virulence genes and antimicrobial resistance genes in staphylococci isolated at Malamulo hospital in Malawi.
… antimicrobial resistance genes (mecA, ermA, ermB, ermC, tetK, tetL, tetM and tetO) and virulence genes (PVL (lukS-PV and lukF-PV), splA, splB, splC, splD, splE, and splF) respectively. The spa gene was sequenced after which Spa typing was also done. Descriptive statistics were used for …

From gut microbiome to pathogen genomics: Understanding antimicrobial resistance in Southeast Asia and Salmonella Paratyphi A
… and tetracycline resistance genes (e.g., ermB and tetA) were the most prevalent. Notably, children were identified as a significant reservoir of AMR genes. In India, the only AMR marker detected in S. Paratyphi A isolates were mutations in gyrA, which is associated with reduced …

A clinical and molecular analysis of Clostridium difficile strains isolated from Groote Schuur Hospital
… 017. ERY-resistant strains all harboured the ermB gene, suggesting that this was the genetic basis of the observed phenotype. Auto-aggregation analysis revealed that the ribotype 017 strains were significantly stronger auto-aggregators than the other ribotypes examined. Results of …
