Abstract
ABSTRACT
The prevalence of acquired resistance in 146
Enterococcus faecium
and 166
Enterococcus faecalis
strains from farm and pet animals, isolated in 1998 and 1999 in Belgium, against antibiotics used for growth promotion and for therapy was determined. Acquired resistance against flavomycin and monensin, two antibiotics used solely for growth promotion, was not detected. Avoparcin (glycopeptide) resistance was found sporadically in
E. faecium
only. Avilamycin resistance was almost exclusively seen in strains from farm animals. Resistance rates were higher in
E. faecium
strains from broiler chickens than in strains from other animal groups with tylosin and virginiamycin and in
E. faecalis
as well as in
E. faecium
strains with narasin and bacitracin. Resistance against ampicillin was mainly found among
E. faecium
strains from pets and was absent in
E. faecalis
. Tetracycline resistance occurred most often in strains from farm animals, while enrofloxacin resistance, only found in
E. faecalis
, occurred equally among strains from all origins. Resistance against gentamicin was very rare in broiler strains, whereas resistance rates were high in strains from other origins. It can be concluded that resistance against antibiotics used solely for growth promotion was more prevalent in
E. faecium
strains than in
E. faecalis
strains. With few exceptions, resistance against the different categories of antibiotics was more prevalent in strains from farm animals than in those from pets.
