The results imply that the blaIMP gene cassettes have been dispersing into various gram-negative rods with the help of the newly identified integron element, which will be helpful for the early recognition of emerging bla IMP-positive clinical isolates which demonstrate consistent resistance to beta-lactams.

Klebsiella pneumoniae NU2936 was isolated from a patient and was found to produce a plasmid-encoded beta-lactamase (MOX-1) which conferred resistance to broad spectrum beta-lactams, including…
CTX-M-27- and CTX-M-14-producing, ciprofloxacin-resistant Escherichia coli of the H30 subclonal group within ST131 drive a Japanese regional ESBL epidemic.

This Japanese regional ESBL-producing E. coli epidemic is closely associated with newly identified CTX-M-27- and CTX -M-14-producing ST131 H30R subclonal groups and with mobile elements IS26, ISEcp1 and IS903D.
Surgical Site Infection in Living-Donor Liver Transplant Recipients: A Prospective Study

A BO incompatibility and repeat surgery increased the risk of developing SSIs with secondary bacteremia, which correlated with poor prognosis, and univariate analysis revealed that adult recipients, ABO incompatibility, total operation duration, repeat surgery, and NNIS risk index were associated with secondarybacterexia.

CF therapy may represent an effective alternative to carbapenem treatment for patients with ESBL-EC bacteremia for empirical and definitive therapy in adult patients who do not have hematological malignancy and neutropenia.
Genomic DNA fingerprinting by pulsed-field gel electrophoresis as an epidemiological marker for study of nosocomial infections caused by methicillin-resistant Staphylococcus aureus
