Abstract Antimicrobial resistance (AMR) is a major threat to global health. Understanding the emergence, evolution, and transmission of individual antibiotic genes (ARGs) essential develop sustainable strategies combatting this threat. Here, we use metagenomic sequencing analyse ARGs in 757 sewage samples from 243 cities 101 countries, collected 2016 2019. We find regional patterns resistomes, these differ between subsets corresponding drug classes are partly driven by taxonomic variation....
ABSTRACT Listeria monocytogenes presents a significant concern for the food industry due to its ability persist in processing environment. One of factors contributing persistence is decreased sensitivity disinfectants. Our objective was assess diversity L. disinfectants by testing response 1,671 L . isolates quaternary ammonium compounds (QACs) and 414 peracetic acid (PAA) using broth microdilution growth curve analysis assays, respectively, categorize into sensitive tolerant. A high...
The human pathogen Listeria monocytogenes is a large concern in the food industry where its continuous detection products has caused string of recalls North America and Europe. Most recognized for ability to grow foods during refrigerated storage, L. can also tolerate several other food-related stresses with some strains possessing higher levels tolerances than others. objective this study was use combination phenotypic analyses whole genome sequencing elucidate potential relationships...
AbstractThis study investigated the dynamics of static biofilm formation (100% RH, 15 °C, 48–72 h) and desiccation survival (43% 21 days) Listeria monocytogenes, in dual species biofilms with common spoilage bacteria, Pseudomonas fluorescens, Serratia proteamaculans Shewanella baltica, on surface food grade stainless steel. The Gram-negative bacteria reduced maximum population L. monocytogenes increased its inactivation during desiccation. However, due to higher resistance relative P....
Foods and related processing environments are commonly contaminated with the pathogenic Listeria monocytogenes. To investigate potential environmental reservoirs of spp. L. monocytogenes, surface water point source pollution samples from an urban a rural municipal supply watershed in Nova Scotia, Canada, were examined over 18 months. Presumptive cultured 72 35% samples, respectively, 24% positive containing two or three different The innocua (56%) welshimeri (43%) groups predominant...
Listeria monocytogenes strains are known to harbour plasmids that confer resistance sanitizers, heavy metals, and antibiotics; however, very little research has been conducted into how may influence L. monocytogenes' ability tolerate food-related stresses. To investigate this, a library (n = 93) of plasmid sequences were compared. Plasmid divided two groups (G1 G2) based on repA phylogeny. Twenty-six unique types observed, with 13 belonging each the repA-based groups. G1 significantly (p <...
Listeria monocytogenes is a foodborne pathogen whose survival in food processing environments may be associated with its tolerance to desiccation. To probe the molecular mechanisms used by this bacterium adapt desiccation stress, transposon library of 11,700 L. mutants was screened, using microplate assay, for strains displaying increased or decreased (43% relative humidity, 15°C) tryptic soy broth (TSB). The phenotypes selected were subsequently assessed on food-grade stainless steel (SS)...
