Background Enterococci are opportunistic pathogens causing severe urinary tract infections, surgical wound infections, bacteremia and bacterial endocarditis. Aggregation substance (asa1), hemolysin/ cytolysin (cylA), gelatinase (gelE), enterococcal surface protein (esp), hyaluronidase (hyl) and biofilm formation are the major virulence determinants responsible for pathogenicity of enterococci. ...

Enterococci are important human pathogens that are increasingly resistant to antimicrobial agents. These organisms were previously considered part of the genus Streptococcus but have recently been reclassified into their own genus, called Enterococcus. To date, 12 species pathogenic for humans have been described, including the most common human isolates, Enterococcus faecalis and E. faecium. E...

Land application of manure from tylosin-treated swine introduces tylosin, tylosin-resistant enterococci, and erythromycin resistant rRNA methylase () genes, which confer resistance to tylosin. This study documents the persistence and transport of tylosin-resistant enterococci, genes, and tylosin in tile-drained chisel plow and no-till agricultural fields treated with liquid swine manure in alte...

conclusions according to these findings, antibiotic-resistance patterns have changed, and vancomycin resistance, especially among e. faecium, is rising because of nosocomial infections. consequently, it has become a serious subject for patients admitted into a hospital. results a total of 53 enterococci were isolated from clinical samples of blood, urine, wounds, sputum, and cerebrospinal fluid...

Surface and groundwater collected in the municipality of Natitingou constitute a potential infectious risk for human health environment due to pathogenic bacteria Chlorella vulgaris they contain after conservation tanks. In this study, surface samples were analyzed according. The results physicochemical bacteriological characterization these water revealed average values pH (4.35 6.98), turbidi...

ABSTRACT: Enterococci have been used as sentinel organisms for monitoring antimicrobial resistance in food, humans, and other animals. In this sense, the present study evaluated susceptibility profile presence of genes associated with to erythromycin (msrC ermB) tetracycline [tet(M) and/or tet(L)] enterococci isolated from raw sheep’s milk cheeses (colonial, feta-, pecorino-type) South region B...

background and objectives: infection with vancomycin-resistant enterococci (vre) has caused a therapeutic problem. vana and vanb resistant types are the predominant phenotypes among vancomycin resistant enetrococci. transposon 1546 (tn1546) harboring the vana gene cluster, plays an important role in the horizontal transfer of vana gene. in this study, we examined the phenotypic and genotypic di...
