Antibioticka rezistence izolatu Enterococcus faecalis a Enterococcus faecium z potravniho retezce.

Enterococci are ubiquitous microorganisms, but the gastrointestinal tract of humans and animals is their predominant habitat. Particularly, in recent years enterococci have emerged as pathogens in association with nosocomial and other serious infections of humans. This can be partly explained by the increasing resistance of some of these bacteria to most antibiotics that are currently used. The increase of the antibiotic resistance is due to inappropriate use of antibiotics in animals and humans. The wide distribution of enterococci and their resistance to extreme temperatures, pH and salinity implies that this group of organisms including antibiotic resistant isolates may also gain access to raw materials (meat and milk) and foodstuffs. Ingestion of food contaminated with resistant enterococci may result in colonisation or infection of humans or transfer of resistance genes to human enterococci or to other bacteria including pathogens. The purpose of this study was: to gain information about the occurrence of enterococci in beef and meat products, in milk and milk products, and about the prevalence of resistant isolates, especially E. faecalis and E. faecium, in these samples; to consider the importance of the food chain as a source of resistant enterococci and through them of antibiotic resistance genes.Available from STL Prague, CZ / NTK - National Technical LibrarySIGLECZCzech Republi
