evolution of acquired resistance to third-generation cephalosporins in enterobacteriaceae in a tunisian hospital 1993-2001.between january 1993 and december 2001, the overall frequency of resistance to third-generation cephalosporins in isolates of enterobacteriaceae from charles nicolle hospital, tunis, rose from 2.4% to 7.4%. klebsiella pneumoniae was the most prevalent species (56%), followed by escherichia coli (15%) and proteus mirabilis (9%). a rate of 49% was observed among isolates from paediatric patients in 1999, caused mostly by outbreaks in the neonatal intensive care unit of k. pneumoniae and p. mirabil ...200415214883
species incidence and antimicrobial-agent resistance patterns of enterobacteriaceae in charles nicolle hospital, tunis, from 1983 to 1987.between july 1983 and december 1987, 13,108 strains of enterobacteriaceae were isolated at charles nicolle hospital in tunis. this study reports the prevalence of different species isolated, their resistance and the evolution of bacterial resistance during that period. there appeared to be a great stability in the distribution of bacterial groups. among the commonly sensitive species, proteus mirabilis showed a high proportion of strains resistant to ampicillin (79.3%), carbenicillin (75.9%), ce ...19911823087
