Antibiotic Resistance in CampylobacterStrains Isolated from Animals, Foods, and Humans in Spain in 1997–1998
ABSTRACT Colonization by Campylobacter strains was investigated in human, broiler, and pig fecal samples from 1997- 1998, as well as in foods of animal origin, and antibiotic susceptibility testing… Expand

Multilocus Sequence Typing Scheme for Enterococcus faecalis Reveals Hospital-Adapted Genetic Complexes in a Background of High Rates of Recombination
ABSTRACT A multilocus sequence typing (MLST) scheme based on seven housekeeping genes was used to investigate the epidemiology and population structure of Enterococcus faecalis. MLST of 110 isolates… Expand
