From 125 separate cloacal cultures from three turkey flocks fed virginiamycin, 104 Enterococcus faecium and 186 Enterococcus faecalis isolates were obtained. As the turkeys aged, there was a higher percentage of quinupristin-dalfopristin-resistant E. faecium isolates, with isolates from the oldest flock being 100% resistant. There were no vancomycin-resistant enterococci. Results of pulsed-fiel...

Background:
 Enterococcus faecalis is one of the most pathogenic bacteria that causes severe infections and antibiotic resistance diseases are related to many animals such as reptiles, insects, birds, mammals humans. considered a cytolysin has ability lysis blood, it was isolated from pathological samples teeth caries intestinal include urine feces. In this article, we discuss general char...

BACKGROUND Glycerol 3-phosphate cytidylyltransferase (GCT) is an enzyme central to the synthesis of teichoic acids, components of the cell wall in gram positive bacteria. Catalysis by GCT from Enterococcus faecalis and Listeria monocytogenes has been investigated and catalytic properties compared. MATERIAL/METHODS The genes encoding GCT were cloned from genomic DNA and recombinant proteins ex...

introduction: the aim of the present in vitro study was to evaluate the disinfection ability of 980-nm diode laser in comparison with sodium hypochlorite (naocl) as a common root canal irrigant in canals infected with enterococcus faecalis ( e. faecalis ). methods and materials: the root canals of 18 extracted single-rooted premolars were prepared by rotary system. after decoronation, the roots...

introduction: the ultimate goal of endodontic treatment is to eliminate the bacterial infection in the root canal system. while mechanical debridement combined with chemical irrigation removes the bulk of microorganisms, residual bacteria are readily detectable in approximately one-half of teeth just prior to obturation. laser light can be used to destroy bacteria. this in vitro study was perfo...

statement of problem: it is necessary to use irrigation solutions during cleaning and shaping of root canals to efficiently reduce the number of micro organisms. sodium hypochlorite is used as an effective antibacterial endodontic irrigants. however, the extract of pennyroyal plant has also shown anti-bacterial characteristics comparable with antibacterial drugs. objectives: to compare the anti...

Enterococci are important nosocomial pathogens that are increasingly difficult to treat due to intrinsic and acquired resistance to antibiotics, including vancomycin. A recently described capsular polysaccharide (CP) isolated from Enterococcus faecalis 12030 was used to evaluate the potential efficacy of active or passive immunotherapy regimens as adjunctive treatments. Evaluation of protective...

The probiotic properties of Enterococcus (E.) faecalis PSCT3-7, a new strain isolated from the intestines of pigs fed dietary fiber containing 50% sawdust, were investigated. E. faecalis PSCT3-7 tolerated a pH range of 3 to 8 and 0.3% bile salts, and it inhibited the growth of Salmonella Typhimurium in a concentration-dependent manner. In addition, E. faecalis showed resistance to several antib...
