a novel ctx-m beta-lactamase (ctx-m-8) in cefotaxime-resistant enterobacteriaceae isolated in brazil.	to estimate the diversity of extended-spectrum beta-lactamases in brazil, 18 strains from different species of the family enterobacteriaceae exhibiting a positive double-disk synergy test were collected by a clinical laboratory from several hospitals in rio de janeiro, brazil, in 1996 and 1997. four strains (proteus mirabilis, enterobacter cloacae, enterobacter aerogenes, and citrobacter amalonaticus) hybridized with a 550-bp ctx-m probe. the p. mirabilis strain produced a ctx-m-2 enzyme. the e. ...	2000	10858358
clonal dissemination of oxa-370-producing klebsiella pneumoniae in rio de janeiro, brazil.	enzymes of the oxa-48 family have become some of the most important beta-lactamases in the world. a new oxa-48 variant (oxa-370) was first described for an enterobacter hormaechei strain isolated in rio grande do sul (southern region of brazil) in 2013. here we report detection of the blaoxa-370 gene in 24 isolates belonging to three enterobacteriaceae species (22 klebsiella pneumoniae isolates, 1 enterobacter cloacae isolate, and 1 enterobacter aerogenes isolate) collected from five hospitals i ...	2015	25987619
