Antimicrobial susceptibility testing and tentative epidemiological cut-off values for family species intended for ingestion.

Introduction: In this work, 170 strains covering 13 species from the family were analyzed to determine minimal inhibitory concentration (MIC) distributions to nine antimicrobial agents, and genes potentially conferring resistance. This allows a proposal of tentative Epidemiological Cut-Offs (ECOFFs) that follows the phylogeny for interpretation of resistance in the 13 species.

Methods: The 170 strains originated from different sources, geographical areas, and time periods.

Complete Genome Sequences of Extraintestinal Pathogenic Escherichia coli Clinical Isolates from Danish Ulcerative Colitis Patients.

Extraintestinal pathogenic Escherichia coli (ExPEC) is a potential factor in ulcerative colitis etiology. We report here the complete genome and plasmid sequences of three Escherichia coli isolates, C 237-04 (p7), C 236-04A (p10A), and C 691-04A (p19A), obtained from fecal samples from ulcerative colitis patients in Copenhagen, Denmark.

Intrinsic (L) sub-class in and is associated with a reduced susceptibility toward tetracycline.

Annotations of non-pathogenic bacterial genomes commonly reveal putative antibiotic resistance genes and the potential risks associated with such genes is challenging to assess. We have examined a putative tetracycline (L) gene (conferring low level tetracycline resistance), present in the majority of all publicly available genomes of the industrially important operational group including the species and . The aim was to examine the risk of transfer of the putative (L) in operational group through phylogenetic and genomic position analysis.

Safety of , Bif195, employing a human exercise-induced intestinal permeability model: a randomised, double-blinded, placebo-controlled, parallel group trial.

We have previously shown that the probiotic strain Bif195 alleviates mucosal injury including ulcer formation in the upper intestine induced by non-steroid anti-inflammatory drugs (NSAIDs). Here, we report additional safety use of Bif195 in 126 healthy humans undergoing an exercise-induced intestinal permeability challenge in a double-blinded, placebo-controlled randomised 6-week intervention trial. Intestinal permeability was assessed by urinary lactulose/rhamnose (L/R) ratio.

Genetics and pathology associated with Klebsiella pneumoniae and Klebsiella spp. isolates from North American Pacific coastal marine mammals.

Southern sea otters (SSO: Enhydra lutris nereis) are a federally-listed threatened subspecies found almost exclusively in California, USA. Despite their zoonotic potential and lack of host specificity, K. pneumoniae and Klebsiella spp.
