Listeria monocytogenes is a major foodborne pathogen that can contaminate food products and colonize food-producing facilities. Foodservice operations (FSOp) are frequently responsible for outbreaks due to safety practices failures. We investigated the presence of characterized L. from two FSOp (cafeterias) distributing ready-to-eat meals verified FSOp's compliance with good manufacturing (GMP). Two facilities (FSOp-A FSOp-B) were visited three times each over 5 months. sampled foods,...
The objective of this study is the rheological characterization photocrosslinked alginate hydrogels synthesized from methacrylated macromonomers. We first optimized acquisition parameters for hydrogels, that is, we studied influence geometries diameter, distance between plates (gap), and solvent trap in response. Our results show important variations shear storage modulus, G', yield strain with three measured. Secondly, experimental parameters, tests were performed on under different...
Carbapenemase-producing carbapenem-resistant Enterobacterales (CP-CRE) represent a significant global threat. The emergence of dual CP-CRE is particularly alarming, as they can potentially compromise the efficacy newer antibiotics, further decreasing therapeutic alternatives. Herein, we report multiple species recovered from invasive infections in Chile that simultaneously harbor blaKPC and blaNDM provide an in-depth genomic characterization these worrisome pathogens. We collected (CRE)...
Abstract Background Carbapenem-resistant Enterobacterales (CRE) are a major public health threat, largely due to the presence of carbapenemases, which globally disseminated in mobile genetic elements. The emergence CRE carrying multiple carbapenemases has been reported several countries, particularly after COVID-19 pandemic. In this study, we report dual-producing (DP-CRE) Chile and provide phenotipic genomic characterization using whole-genome sequencing (WGS). Methods We evaluated...
