Cross-transmission of Acinetobacter junii carrying blaOXA-58 in a neonatal ICU.

Background: Nasal colonization of two preterm infants in our neonatal ICU by Acinetobacter junii carrying the blaOXA-58 carbapenem resistance gene was demonstrated.

Objectives: To study whether the two isolates were identical and to investigate the hypotheses of cross-transmission.

Methods: Antibiotic susceptibility tests of the two isolates were performed by standard diffusion and the MICs of carbapenems determined by the MIC-gradient strip method.

Acquisition of plasmid-mediated cephalosporinase producing Enterobacteriaceae after a travel to the tropics.

Travelers are at high risk of acquiring multi-drug resistant Enterobacteriaceae (MRE) while traveling abroad. Acquisition of extended spectrum beta-lactamase producing Enterobacteriaceae (ESBL-E) while traveling has been extensively described, but not that of plasmid-mediated cephalosporinase producing Enterobacteriaceae (pAmpC-E). Here, we characterized the pAmpC-E acquired in 574 French travelers to tropical areas enrolled in the VOYAG-R study.
