In the held of human medicine in the last time, several strains of the enterococcus (E.) genus have been gaining significance as facultative pathogenic agents. While as recently as 10 years ago enterococci did not figure as nosocomial septic agents, today they are held responsible fur a fifth of all general septic infections, This rise is caused of all to the special capability of these agents to develop resistance to substances with anti-microbial effects. The target of the study was to demonstrate the incidence and resistance behaviour of vanycomycin-resistant enterococci (VRE), as well as the connections between the different types of resistance to glycopeptide and the use of Avoparcin in livestock production. Avoparcin is a glycopeptide: it was used in livestock breeding as performance booster and has ii structural formula similar to that of Teicoplanin and Vancomycin. Since January 1996. however, the use of Avoparcin has been outlawed due to the fact that it must be assumed that cross-over resistances can develop and lead to the creation ofa resistance pool. The samples examined are isolated from poultry-breeding farms. In order toinvestigate the potential links described above, enterprises with different operating forms were chosen. These were conventional poultry farms, on the one hand, i.e. large-scale operations which potentially use of Avoparcin (until its prohibition) as feed additive, and on the other hand ecological operations. i.e. small-scale farms raising livestock without medicinal additives in feed. To collect data on a spectrum as wide as possible, samples were taken fromthe following areas: poultry house, slaughterhouse. and carcass. From the various areas 223 samples were taken, and 281 VRE strains were isolated, Initially, the species was identified in line with culture-morphological, biochemical and serological criteria. Once this was done. the glycopeptide sensitivity was tested by means of the microdilution method. 60.1% of all samples (small-scale farms and large-scale farms) proved to be VRE positive, 87.8% of all samples originated from conventional large-scale farms. and 30.5% of all samples from small-scale farms. In the case of the VRE isolates. these were exclusively E. faecium strains with high-level resistance behaviour. In relation to the bacterial contamination (total viable count, Enterobacteriaceae: and enterococcus spp.) samples from conventional production in general were less contaminated than those derived from ecological operations.
