Acinetobacter baumannii is a nosocomial pathogen that has emerged as a global threat
because of high levels of resistance to many antibiotics, particularly those considered to be …

The genus Acinetobacter is a major cause of nosocomial infections; it is increasingly being
associated with various epidemics and has become a widespread concern in a variety of …

Class D β-lactamase-mediated resistance to β-lactams has been increasingly reported

To assess dissemination of OXA-23–producing strains of Acinetobacter baumannii, we
obtained 20 carbapenem-resistant, OXA-23–producing isolates from different regions. Their …

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 …

Acinetobacter baumannii is an opportunistic gram-negative pathogen with increasing
relevance in a variety of nosocomial infections especially among intensive-care-unit (ICU) …

The oxa23 gene encoding the OXA-23 carbapenemase (and several minor variants of it) is
widespread in Acinetobacter baumannii clinical isolates and compromises treatment with …

This review describes the current state-of-art of carbapenemase detection methods.
Identification of carbapenemases is first based on conventional phenotypic tests including …

The Class D β-lactamases have emerged as a prominent resistance mechanism against β-
