Among 42 gram-negative bloodstream isolates from inpatients in 3 hospitals in Yangon, Myanmar, admitted during July-December 2014, 16 (38%) were extended-spectrum β-lactamase-producing Enterobacteriaceae and 6 (14%) produced carbapenemase. The high prevalence of multidrug-resistant gram-negative bacteria raises concerns about the empiric treatment of patients with sepsis in Yangon.

Jing Wang, Zhen-Bao Ma, Zhen-Ling Zeng, Xue-Wen Yang, Ying Huang, Jian-Hua Liu
Antimicrobial resistance is an urgent global health challenge in human and veterinary medicine. Wild animals are not directly exposed to clinically relevant antibiotics; however, antibacterial resistance in wild animals has been increasingly reported worldwide in parallel to the situation in human and veterinary medicine. This underlies the complexity of bacterial resistance in wild animals and the possible interspecies transmission between humans, domestic animals, the environment, and wildlife. This review summarizes the current data on expanded-spectrum β-lactamase (ESBL), AmpC β-lactamase, carbapenemase, and colistin resistance genes in Enterobacteriaceae isolates of wildlife origin...

Carbapenemase-producing organisms, or CPOs, are gram-negative pathogens that produce a transmissible carbapenemase and are typically resistant to most, sometimes all, antibiotics. We now face a global CPO pandemic of high mortality. In this issue of the Journal of Clinical Microbiology, J. A. Karlowsky et al (J. Clin Microbiol 55: xxxx-xxyy, 2017, https://doi.org/10.1128/JCM.02316-16) report the results of an extensive global surveillance study that provides much-needed information that enhances our understanding of carbapenemase-producing Enterobacteriaceae (CPE) and which will be valuable for the development of improved strategies for CPE control and therapy of infections...

The global spread of carbapenemase-producing Enterobacteriaceae (CPE) that are often resistant to most, if not all, classes of antibiotics is a major public health concern. NDM-1 carbapenemase is among the most worrisome carbapenemases given its rapid worldwide spread. We have developed and evaluated a lateral flow immunoassay (LFIA, called NDM LFIA) for rapid and reliable detection of NDM-like carbapenemase-producing Enterobacteriaceae from culture colonies.We evaluated the NDM LFIA using 175 reference enterobacterial isolates with characterized ß-lactamase gene content and 74 non-duplicate consecutive carbapenem-resistant clinical isolates referred for expertise to the French National Reference Center (NRC) for antibiotic resistance during a one-week period (in June 2016)...

In Denmark, the incidence of carbapenemase-producing organisms (CPO) is increasing, and a coordinated national strategy is needed. We describe a case story of a 40-year-old woman transferred to a Danish hospital with severe complications after cosmetic surgery in the Middle East. She had an intra-abdominal infection with three different CPO, one of them co-resistant to colistin, one of the few remaining antibiotics for CPO treatment. Because of good clinical response to surgical treatment, antibiotics covering these multiresistant bacteria were not given...

Carbapenemase-producing Enterobacteriaceae are an emerging threat to hospitals worldwide and antibiotic exposure is a risk factor for developing fecal carriage that may lead to nosocomial infection. Here we review how antibiotics reduce colonization resistance against Enterobacteriaceae to pinpoint possible control points for curbing their spread. Recent work identifies host-derived respiratory electron acceptors as a critical resource driving a post-antibiotic expansion of Enterobacteriaceae within the large bowel...
