Klebsiella species are a common cause of community- and nosocomial-acquired pneumonia. Antibiotic resistance to the class of carbapenem in patients with pneumonia caused by Klebsiella species is unusual. New studies report carbapenem resistance in patients with pneumonia caused by Klebsiella species.This article examines, retrospectively, antibiotic resistance in patients with community- and no...

Carbapenem-resistant Acinetobacter baumannii (CRAB) is a gram-negative bacillus that commonly causes nosocomial infection found in Indonesia. CRAB caused by resistant to Carbapenem. Resistance occurred because bacteria cause infections easily treated with antibiotics become difficult treat due the uncontrolled use of antibiotics. A. has been against carbapenem class antibiotics; and therefore, ...

BACKGROUND With an increase in the use of colistin methansulfonate (CMS) to treat carbapenem-resistant Acinetobacter baumannii infections, colistin resistance is emerging. METHODS Patients with infection or colonization due to colistin-resistant A. baumannii were identified at a hospital system in Pennsylvania. Clinical data were collected from electronic medical records. Susceptibility testi...

BACKGROUND Resistance to beta-lactam antibiotics is widespread among Acinetobacter strains. Plasmid-mediated metallo beta lactamases (MBL) are responsible for carbapenem resistance, as are oxacillinases (OXA). In recent years, MBL producing carbapenem-resistant strains have been reported in the world and in Turkey in increasing rates. In our country, besides the OXA 51-like enzyme which is inhe...

OBJECTIVES We investigated the activity of BAL30072, a dihydroxypyridone monosulfactam, against carbapenem-resistant Enterobacteriaceae and non-fermenters (i) alone, (ii) combined with BAL29880 (to inhibit AmpC) and/or clavulanate [to inhibit extended-spectrum β-lactamases (ESBLs)] and (iii) combined 1:1 with meropenem. METHODS Isolates were from multiple UK hospitals. MICs were determined by...

Acquired carbapenemases currently pose one of the most worrying public health threats related to antimicrobial resistance. A NDM-1-producing Salmonella Corvallis was reported in 2013 in a wild raptor. Further research was needed to understand the role of wild birds in the transmission of bacteria resistant to carbapenems. Our aim was to investigate the presence of carbapenem-resistant Escherich...

AIM To evaluate the diagnostic performance of MDI and temocillin disk (30 μg) for detection of carbapenem-resistant Enterobacteriaceae in comparison to real-time PCR. MATERIAL AND METHODS Fifty specimens submitted to the Microbiology Laboratory of Ain Shams University Hospitals and showed resistance to carbapenem drugs through routine culture and susceptibility testing, were assessed by both ...

A collection of 94 Gram-negative bacteria isolates, showing different antimicrobial resistance phenotypes including to the carbapenem classes was investigated. Strains were originated form clinical sources from a single hospital in Tripoli, Libya during 2015 and were identified based on cultural and phenotypic characteristics, and fully characterized by the VITEK automated system. Forty-eight p...

During 2005 we detected a multicity outbreak of infections or colonization due to high-level imipenem-resistant Acinetobacter baumannii (MIC, 64 microg/ml). One hundred isolates from diverse sources were obtained from seven acute-care hospitals and two extended-care facilities; 97% of the isolates belonged to one clone. Susceptibility testing of the first 42 isolates (January to April 2005) rev...

OBJECTIVES An extremely drug-resistant (XDR) clone of KPC-3-producing Klebsiella pneumoniae emerged in Israel in 2006, causing a nationwide outbreak. We aimed to characterize the local KPC-3-encoding plasmid carried by these isolates and study its contribution to antibiotic resistance. METHODS Mechanisms of carbapenem resistance were investigated in seven selected isolates (isolated between 2...
