Background. Preventing the spread of carbapenem-resistant Enterobacteriaceae (CRE) is important to public health because of high infection-related morbidity, mortality, and cost. Carbapenemase producing (CP)-CRE are most concerning because of their rapid global dissemination. In 2013, CRE in Oregon were defined as Enterobacteriaceae with non-susceptibility to ≥1 carbapenem, including ertapenem,...

Carbepenems are used with increasing frequency to treat multidrug-resistant isolates, especially strains producing extended-spectrum β-lactamases [1, 2]. Resistance to carbapenems has been uncommon among Enterobacteriaceae. However, the emergence of β-lactamases with direct carbapenem-hydrolyzing activity has contributed to an increased prevalence of carbapenem-resistant Enterobacteriaceae (CRE...

Metallo-beta-lactamases (MBLs) can confer resistance to most beta-lactams, including carbapenems. Their emergence in gram-negative pathogens is a matter of major concern. Italy was the first European country to report the presence of acquired MBLs in gram-negative pathogens and is one of the countries where MBL producers have been detected repeatedly. Here, we present the results of the first I...

During the past decade, there has been an emergence of carbapenems-resistant Enterobacteriaceae that produce carbapenamases, enzymes that efficiently hydrolyze carbapenems, as well as most βlactam drugs (Queenan et al., 2007). New Delhi Metallo-beta-lactamases-1 (NDM-1) are one such carbapenamase that makes bacteria resistant to a broad range of betalactam antibiotics. These include the antibio...

In recent years, environmental pollution by coal mining is a long-established human activity affecting all levels of life with various environmental impacts by generating heavy metals. The presence of heavy metals even in trace amount is toxic and detrimental to all living organisms. The coal mine area in Bokaro is one of the “Toxic Hotspot” in India. Bacteria have evolved uptake and efflux mec...

The Ministry of Health and Welfare, Japan banned coadministration of carbapenems, such as panipenem/betamipron (PAPM), meropenem (MEPM), and valproic acid (VPA) because clinical reports have indicated that the coadministration caused seizures in epileptic patients due to lowered plasma levels of VPA. In this study, we have clarified the mechanism of the drug-drug interaction using PAPM, MEPM, a...

AIM The aim of this study was to characterize beta-lactamase antimicrobial resistance in Klebsiella and Enterobacter species isolated from healthy and diarrheic dogs in Andhra Pradesh. MATERIALS AND METHODS A total of 136 rectal swabs were collected from healthy (92) and diarrheic (44) dogs, bacteriological cultured for Klebsiella and Enterobacter growth and screened for beta-lactamase antimi...

Resistance to carbapenems has been documented by the production of carbapenemase or the loss of porins combined with extended-spectrum β-lactamases or AmpC β-lactamases. However, no complete comparisons have been made regarding the contributions of each resistance mechanism towards carbapenem resistance. In this study, we genetically engineered mutants of Klebsiella pneumoniae with individual a...
