The OXA β-lactamases were among the earliest β-lactamases detected; however, these
molecular class D β-lactamases were originally relatively rare and always plasmid …

Multilocus sequence typing reveals that many bacterial species have a clonal structure and
that some clones are widespread. This underlying phylogeny was not revealed by pulsed …

The rapid expansion of Acinetobacter baumannii clinical isolates exhibiting resistance to
carbapenems and most or all available antibiotics during the last decade is a worrying …

Class D β-lactamase-mediated resistance to β-lactams has been increasingly reported
during the last decade. Those enzymes also known as oxacillinases or OXAs are widely …

During the past few decades Acinetobacter baumannii has evolved from being a commensal
dweller of health-care facilities to constitute one of the most annoying pathogens …

Background Acinetobacter baumannii is an opportunistic pathogen that causes serious
nosocomial infection in intensive care units. In particular, carbapenem-resistant A …

To monitor national antimicrobial resistance (AMR), the Korea Global AMR Surveillance
System (Kor-GLASS) was established. This study analyzed bloodstream infection (BSI) …

Multidrug resistance has been increasing among Gram-negative bacteria and is strongly
associated with the production of both chromosomal-and plasmid-encoded β-lactamases …

Acinetobacter spp. are Gram-negative bacteria that have become one of the most difficult
pathogens to treat. The species A. baumannii, largely unknown 30 years ago, has risen to …

Infections due to Gram-negative bacilli (GNB) are a leading cause of morbidity and mortality
worldwide. The extent of antibiotic resistance in GNB in countries of the Gulf Cooperation …
