Draft Genome Sequence of sp. Strain CaF467b, Isolated from a Pig Manure Storage Tank.

In this report, we present the draft genome sequence of an unclassified strain, CaF467b. This bacterial isolate was recovered from a pig manure storage tank. The draft genome sequence is 1,655,514 bp in length with 1,709 predicted genes and a G+C content of 34.

Mobility of -lactam resistance under ampicillin treatment in gut microbiota suffering from pre-disturbance.

Ingestion of food- or waterborne antibiotic-resistant bacteria may lead to dissemination of antibiotic resistance genes (ARGs) in the gut microbiota. The gut microbiota often suffers from various disturbances. It is not clear whether and how disturbed microbiota may affect ARG mobility under antibiotic treatments.

Complete Genome Sequence of a Canadian Strain of Raoultella planticola with Metal and Antimicrobial Resistance Genes.

Raoultella planticola is a Gram-negative opportunistic bacterial pathogen associated with hospital-acquired infections in humans. Here, we report the complete genome sequence of one Raoultella planticola strain isolated from Canadian wastewater treatment facilities containing one chromosome and four plasmids with four antimicrobial resistance (AMR) genes and four metal resistance gene clusters.

A comparison of fourteen fully characterized mammalian-associated isolates suggests that loss of defense mechanisms contribute to high genomic plasticity and subspecies evolution.

is currently classified into three main subspecies, but only two of these, subspecies and subsp. v originate principally from ruminants where they inhabit different niches and cause distinct pathogenicity. Their importance as pathogens in international trade and reporting is also different yet the criteria defining these properties have never been fully substantiated nor understood.

Complete Genome Sequence of a Canadian Klebsiella michiganensis Strain, Obtained Using Oxford Nanopore Technologies Sequencing.

is a Gram-negative opportunistic pathogen that is associated with many hospital-acquired infections in humans. Here, we report the complete genome sequence of a strain isolated from a Canadian wastewater treatment facility.

Mobility of β-Lactam Resistance Under Bacterial Co-infection and Ampicillin Treatment in a Mouse Model.

Ingestion of food- or waterborne antibiotic-resistant bacteria may lead to the dissemination of antibiotic-resistance genes in the gut microbiota and the development of antibiotic-resistant bacterial infection, a significant threat to animal and public health. Food or water may be contaminated with multiple resistant bacteria, but animal models on gene transfer were mainly based on single-strain infections. In this study, we investigated the mobility of β-lactam resistance following infection with single- versus multi-strain of resistant bacteria under ampicillin treatment.

An Unusual Enteritidis Strain Carrying a Modified Virulence Plasmid Lacking the Gene Represents a Geographically Widely Distributed Lineage.

This study identifies a strain of subspecies serovar Enteritidis that harbors a highly unusual virulence plasmid. During the characterisation of a group of Enteritidis isolates, 10 isolates recovered from Canadian duck production facilities, of which seven were phage type 9b and three were closely related atypical phage types, failed detection by a PCR targeting the gene, a marker located on the virulence plasmid often employed for identification of this serovar. Comparison to + isolates by several standard genetic typing tools, further revealed their distinctive genomic makeup.
