OBJECTIVES: Although it has been regarded that CTX-M type extended-spectrum β-lactamase (ESBL) gene, blaCTX-M , is mainly carried by antibiotic-resistance plasmids, Escherichia coli-possessing chromosomally-located blaCTX-M has been reported in previous studies. This study aimed to characterize the genetic structures of chromosomally-located blaCTX-M transposition unit and its surrounding sequence in E. coli isolates-producing ESBL which were obtained in a Japanese hospital. METHODS: In this study, total of 81 ESBL-producing E...

OBJECTIVE: Carbapenem-resistant Acinetobacter baumannii (CRAB) infection has become a worldwide issue. This study aimed to characterize the epidemiology and genetic relationships of A. baumannii in Guangdong Province, China. METHODS: CRAB isolates were collected from five municipal hospitals from June to December 2017. 16S-23S rRNA intergenic spacer(ITS) was used for further strain identification. Antimicrobial susceptibility test and CarbAcineto NP test were performed to analyse antibiotic spectrum and carbapenemase production of those isolates, while PCR-based assays were used to detect beta-lactamase genes and related mobile genetic elements...

OBJECTIVES: To evaluate incidence of single-drug resistant, multidrug-resistant, extensively drug-resistant and pandrug-resistant E. coli urinary tract infections (UTI) in a sample of Australian Capital Territory (ACT) residents. METHODS: We utilised laboratory-based retrospective data from all ACT residents whose urine samples were processed from January 2009 to December 2013. Multivariate logistic regression models were constructed to determine the associations of age, sex, urine sample source and socioeconomic status with risk of resistant infections...

OBJECTIVES: Escherichia coli strains producing extended-spectrum β-lactamases (ESBL), especially of CTX-M type, have been largely described in companion animals; however genomic data are lacking to clarify the clinical impact of ESBL producers in these hosts. The aim of this study was to present genomic features of a highly virulent ceftiofur-resistant CTX-M-8-producing E. coli lineage from a case of pneumonia in cat with fatal outcome. METHODS: Genomic DNA was sequenced using an Illumina NextSeq500 platform and assembled by CLC Genomic Workbench...

OBJECTIVES: The emergence of Enterobacteriaceae isolates resistant to the last-resort fosfomycin antibiotic outside Asia is a public health issue. Here, we report the draft genome of an E. coli presenting both an Extended-Spectrum Beta-Lactamase (ESBL) and the fosA3 gene in a healthy cow in Brazil. METHODS: Whole genomic DNA from E. coli E12 was extracted and 2×150-bp paired-end reads were generated with Illumina sequencing technology. De novo genome assembly was performed using SPAdes v...

METHODS: A total of 4241 invasive isolates of S. pneumoniae were collected in Slovenia from 1997 to 2017. In 612 erythromycin-resistant isolates the presence of erm(B), mef(E), mef(A) and erm(TR) genes were determined by PCR. Selected isolates carrying the mef(A) gene were further examined by PFGE...

BACKGROUND: Staphylococcus aureus causes a variety of manifestations and diseases and has been associated with a high morbidity and mortality rate. A global population drift in the clinical isolates of S. aureus towards reduced antibiotic susceptibility is being reported. Thus, we studied the antimicrobial susceptibility profile and minimum inhibitory concentration (MIC) creep of vancomycin, linezolid, teicoplanin and rifampicin against clinical isolates of Staphylococcus aureus at an Indian tertiary centre from January 2012 to December 2016...

OBJECTIVES: Azole resistance in Aspergillus fumigatus environmental and clinical isolates is recognized as an emerging problem worldwide. The development of azole resistance may be environmentally driven because of the massive use of azole fungicides in agriculture and the mechanism of resistance is mostly related to mutations in the cyp51A gene. A. fumigatus azole resistance in the environment was previously documented in Northern Italy. The present study extended the research in the agricultural environment also in central and southern Italy and investigated the differences in the Italian geographical areas and in the different types of crops...

BACKGROUND: Bacteroides spp., an anaerobic resident intestinal flora is also known to cause severe morbidity. They are resistant to a wide variety of antimicrobial agents including metronidazole. Specific nitroimidazole (nim) resistance genes have been shown to be associated with the same. Worldwide, metronidazole resistance is emerging, though presently remains around 5%. This study was aimed at metronidazole susceptibility and distribution of nim genes within the Bacteroides spp. We also analyzed the relationship among the strains harboring nim genes and their susceptibility to metronidazole...
