BACKGROUND: The prevalence of carbapenem-resistant Enterobacteriaceae (CRE) has been reported to be lower in Japan than in many other countries. However, extensive surveillance for CRE carriage has not been performed in Japan. AIM: To investigate the prevalence of CRE carriage in Japan among convalescent patients considered to be at high-risk of being CRE carriers using an improved selective culture medium. METHODS: A cross-sectional survey was conducted in 22 acute care hospitals (ACHs) and 21 long-term care hospitals (LTCHs) in northern Osaka from December 2015 to January 2016...

Antimicrobial resistance (AMR) is a major threat to human, animal health, and environment worldwide. For human, transmission occurred through a variety of routes both in health-care settings and community. In animals, AMR was reported in livestock, pets, and wildlife; transmission of AMR can be zoonotic with the probably most important route being foodborne transmission. The Indian Ocean Commission (IOC), composed of Comoros, Madagascar, Mauritius, Reunion (France), and Seychelles recognized the surveillance of AMR in both animal and human as a main public health priority for the region...

Carbapenemase producing Citrobacter freundii (CPCF) infections are still uncommon in European countries. Here we report a molecular study conducted in a tertiary care facility in southern Madrid, Spain, from 2009 to 2014 to investigate the epidemiology of CPCF. The blaIMP-1,blaIMP-2,blaKPC,blaNDM,blaOXA-48,blaVIM-1 and blaVIM-2 genes were screened by PCR. Molecular typing was carried out by Pulsed-field gel electrophoresis analysis (PFGE) and multilocus sequence typing (MLST). Whole genome sequencing (WGS) was performed to characterize the resistome and the mobile genetic elements associated with the carbapenems resistance of CPCF...

This study was conducted using the same method of the "1-day multicenter collaborative research for Clostridium difficile infectious". This surveillance study was performed by 38 participating medical facilities across Japan. Of the 268 fecal specimens collected in this study, 5 (1.9%) carbapenem-resistant Enterobacteriaceae (CRE) were judged carbapenem resistant by the criteria of the Infectious Disease Act, Japan (2 mg/L or more and 64 mg/L or more MICs for imipenem and cefmetazole, respectively). However, no isolate was shown to have a meropenem MIC of 2 mg/L or more...

Despite improvement of infection control measures during the last 20 years, incidence of health care associated infections (HAI) remains high. HAI, also known as nosocomial infections, are mainly due to susceptible bacteria. However, resistant bacteria are responsible for some of them. In Switzerland, methicillin resistant Staphylococcus aureus incidence is decreasing but enterobacteriaceae producing extended spectrum beta-lactamase are increasing. In addition, emerging resistance challenges such as vancomycin-resistant enterococci or carbapenemase-producing bacteria were observed occasionally during recent years...

Plasmid-mediated resistance in Enterobacteriaceae against carbapenems and colistin represents an emerging threat for public health. Although animals have been identified as a relevant source of multidrug-resistant (MDR) bacteria, there are only few reports about the presence of carbapenemases in animal isolates. Using Mueller-Hinton agar with meropenem, 7,850 fecal E. coli isolates obtained from 2,160 pigs were screened for carbapenem non-susceptibility. Eleven isolates showed growth on meropenem agar but only two proved positive for a carbapenemase gene, namely blaOXA-48-like, by PCR...

Extended-spectrum beta-lactamases (ESBL) and carbapenemase-producing organisms pose severe problems for hospitalized patients. In the absence of efficient sanitation and sewage disposal, the risks for transmission of hospital organisms into the community are high. Our objectives were to study the occurrence and mechanisms of resistance of multidrug-resistant gram-negative bacilli in two Lebanese hospital sewage treatment plants. Wastewater samples were collected, filtered, and cultivated on MacConckey+cefotaxime agars...

Carbapenem antibiotics are used as a last resort to treat serious Gram-negative bacteria (GNB) infections; however, carbapenemase-producing strains of GNB have emerged as a major source of resistance. Owing to the highly transmissible nature of plasmid-borne carbapenemases, numerous reports have warned about the likely spread into the community from healthcare settings. Since the prevalence of carbapenem-resistant Enterobacteriaceae (CRE) in the community is largely unknown, we conducted a scoping review of the literature to assess the percentage of CRE isolates that could be associated with the community...

Carbapenemase-producing Enterobacteriaceae have been steadily spreading worldwide during the last decade. Nine patients were identified prospectively and were followed during their hospitalization course to identify the epidemiology, clinical profiles and outcomes. These patients had one or more cultures positive for a CRE isolate, contributing to a total of eleven positive cultures from various sites without including duplicates of isolates obtained from the same site. Isolates from these patients included five Klebseilla pneumoniae, three Escherichia coli, and one Enterobacter aerogenes...

The presence of Methicillin-Resistant Staphylococcus aureus (MRSA) in pig farms has been widely reported, and the emergence of extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) has been documented in several countries. However, data for Switzerland are very scarce. This study aimed to compare changes in the prevalence of MRSA in Swiss pig farms between 2008 and 2015 and make the first ever estimates of the presence of ESBL-E and carbapenemase producers in pigs and pig farm workers. Results showed that ESBL-E was present in both pigs and farm workers and that the proportion of farms with MRSA had increased fourfold in seven years (from 7% to 31%)...
