Antimicrobial susceptibility of commensal Neisseria spp. in parents and their children in Belgium: a cross-sectional survey.

Background: commensal Neisseria species are part of the oropharyngeal microbiome and play an important role in nitrate reduction and protecting against colonization by pathogenic bacteria. They do, however, also serve as a reservoir of antimicrobial resistance. Little is known about the prevalence of these species in the general population, how this varies by age and how antimicrobial susceptibility varies between species.

Distribution of Staphylococcus aureus carriage among healthcare workers in a Japanese convalescent and rehabilitation hospital.

Earlobes, nasal cavities, and fingers of 145 healthcare workers in convalescent and rehabilitation hospital (60 nurses and 85 rehabilitation healthcare workers) were sampled. Of the 3 sites sampled, Staphylococcus aureus was detected in one or more sites in 25 nurses and 27 rehabilitation workers. S.

Epigenetic effects of ceftriaxone-resistant Neisseria gonorrhoeae FC428 mosaic-like sequences found in PenA sequences unique to Neisseria subflava and related species.

Objectives: The aim of this study was to explore the origin of the PenA mosaic amino acid sequence in the ceftriaxone-resistant Neisseria gonorrhoeae FC428 clone.

Methods: The penA sequences of 27 Neisseria subflava pharyngeal isolates were determined by the Sanger method and penA sequences of 52 isolates from nine Neisseria species were obtained from the NCBI database. Comparative analysis of each PenA sequence was performed by multiple sequence alignment using ClustalW.

The emergence of the ceftriaxone-resistant Neisseria gonorrhoeae FC428 clone by transfer of resistance from an oral Neisseria subflava reservoir of resistance.

Background: The ceftriaxone-resistant Neisseria gonorrhoeae FC428 clone was first discovered in Japan in 2015.

Objectives: We investigated the possibility of horizontal gene transfer from Neisseria subflava harbouring the mosaic-like PBP-2 in the emergence of the FC428 clone. We also analysed whether there were fitness costs associated with the sustained international dissemination of the clone.

Molecular characteristics and antimicrobial susceptibility of penicillinase-producing Neisseria gonorrhoeae isolates in Fukuoka, Japan, 1996-2018.

Objectives: The objective of this study was to investigate the molecular characteristics and antimicrobial susceptibility of penicillinase-producing Neisseria gonorrhoeae (PPNG) isolates collected in Fukuoka, Japan, from 1996-2018.

Methods: Antimicrobial susceptibility to seven antibiotics was determined by the agar dilution method. Molecular characteristics were determined by Sanger sequencing of the bla allele, plasmid typing and N.

Does sub-culturing of positive MRSA blood cultures affect vancomycin MICs?

. Empirical vancomycin (VAN) treatment failure for methicillin-resistant (MRSA) bacteraemia, with significantly higher mortality, has been reported for MRSA strains with reduced VAN susceptibility..

Antimicrobial resistance and molecular characterisation of Neisseria gonorrhoeae isolates in Fukuoka, Japan, 1996-2016.

Objectives: Antimicrobial resistance and molecular characteristics of Neisseria gonorrhoeae isolates obtained from 1996-2005 (n=200) and 2008-2016 (n=200) in Fukuoka, Japan, were examined.

Methods: MICs were determined by agar dilution. Sequence types (STs) were examined using N.

In vitro activity of various antibiotics against clinical strains of Legionella species isolated in Japan.

The activities of various antibiotics against 58 clinical isolates of Legionella species were evaluated using two methods, extracellular activity (minimum inhibitory concentration [MIC]) and intracellular activity. Susceptibility testing was performed using BSYEα agar. The minimum extracellular concentration inhibiting intracellular multiplication (MIEC) was determined using a human monocyte-derived cell line, THP-1.

[Bacteriological Properties of Meropenem-resistant Escherichia coli Isolated from Seven Patients within a Month].

From April to May 2014, a total of seven cases of meropenem (MEPM)-resistant Escherichia coli were isolated from the sputum specimens in 7 different patients in a community hospital. The MICs of MEPM for isolates were 8 to 32 μg/mL, whereas the MICs of imipenem (IPM) were 0.5 μg/mL or 1 μg/mL.

[Evaluation of the BD Phoenix ID Yeast System for the Species Identification of Clinical Yeast-Like Organisms].

Most fungi isolated from patients with deep-seated mycosis are yeast-like organisms such as Candida and Cryptococcus. As their respective susceptibilities to antifungal agents can vary depending on the species, rapid identification is important for the administration of appropriate antifungal therapy. The aim of this study was to evaluate the performance of a new automated identification panel, Phoenix Yeast ID (Becton, Dickinson Diagnostics, USA) as well as the time required for identification.

[Decreasing Susceptibility of MRSA to Daptomycin During the Course of Treatment].

Methicillin-resistant Staphylococcus aureus (MRSA) with decreased susceptibility to daptomycin (DAP) were isolated from 4 patients receiving DAP from November 2013 to May 2014. These patients were treated with DAP for more than 7 days in all the cases. The pulsed-field gel electrophoresis (PFGE) patterns for MRSA isolates recovered from each patient pre- and post-DAP therapy were identical.
