The initial state of the human gut microbiome determines its reshaping by antibiotics
It is shown that standard antibiotic treatment can alter the gut microbiome in a specific, reproducible and predictable manner, and a subgroup of participants who were enriched in the opportunistic pathogen Enterobacter cloacae after exposure to the antibiotic, an effect linked to lower initial microbiome diversity and to a Bacteroides enterotype is identified.
Characterization of a Tn5382-like transposon containing the vanB2 gene cluster in a Clostridium strain isolated from human faeces.
The report shows for the first time the presence of a Tn5382-like transposon carrying vanB2 in a Clostridium species of the human intestinal flora, which suggests that the vanB 2 Tn 5382- like transpos on is an important vector for the spread of vancomycin resistance in several bacterial species.

A novel strictly anaerobic, vancomycin-resistant, Gram-positive coccus was isolated from a human faecal specimen and formed a hitherto unknown sublineage within the Clostridium coccoides rRNA cluster of organisms (cluster XIVa).
A Side by Side Comparison of Bruker Biotyper and VITEK MS: Utility of MALDI-TOF MS Technology for Microorganism Identification in a Public Health Reference Laboratory
This study demonstrates that both systems gave a high level of correct identification for a wide range of microorganisms, however, VITEK MS gave more misidentification when the microorganism analysed was not present in the database, compared to Bruker Biotyper.
Penetration of Listeria monocytogenes in mice infected by the oral route.
In this study, it is suggested that the Peyer's patches are the most important point of entry of Listeria monocytogenes in the host after subclinical infection by the oral route. Microbiological,…

The presence of Enterococcus-associated vancomycin resistance genes vanA, vanB, vanD, vanE, and vanG in rectal swabs was investigated in two hospitals using PCR, finding high prevalences of vanB and vanD genes not associated with enterococci.

This immunohistochemistry technique seemed to be at least as sensitive as microbiologic cultures and could be useful in studies of pathogenesis and retrospective diagnosis, however, cross-reactivity with Actinobacillus pleuropneumoniae means that positive immunohistsochemistry results in lung tissue from field cases would be dubious.

First Canadian outbreak of Enterobacteriaceae-expressing Klebsiella pneumoniae carbapenemase type 3.
The dissemination of KPC in Enterobacteriaceae and the consequences for treatment and infection control measures warrant a high degree of vigilance among clinicians and microbiologists.
