M. Gazouli et al., TRANSFERABLE CEFOXITIN RESISTANCE IN ENTEROBACTERIA FROM GREEK HOSPITALS AND CHARACTERIZATION OF A PLASMID-MEDIATED GROUP-1 BETA-LACTAMASE (LAT-2), Antimicrobial agents and chemotherapy, 40(7), 1996, pp. 1736-1740
Cefoxitin resistance in Klebsiella pneumoniae and Escherichia coli str
ains isolated in Greek hospitals was found to be due to the acquisitio
n of similar plasmids coding for group 1 beta-lactamases. The plasmids
were not self-transferable but were mobilized by conjugative plasmids
. These elements have also been spread to Enterobacter aerogenes, The
most common enzyme was a Citrobacter freundii-derived cephalosporinase
(LAT-2) which differed from LAT-1 by three amino acids.
