Genomic Surveillance of SARS-CoV-2 in México: Three Years since Wuhan, China's First Reported Case.

Objective: The aim of this work was to analyze the metadata of the SARS-CoV-2 sequences obtained from samples collected in Mexico from 2020 to 2022.

Materials And Methods: Metadata of SARS-CoV-2 sequences from samples collected in Mexico up to 31 December 2022 was retrieved from GISAID and manually cured for interpretation.

Results: As of December 2022, Mexican health authorities and the scientific community have sequenced up to 81,983 SARS-CoV-2 viral genomes deposited in GISAID, representing 1.

Population structure of the Salmonella enterica serotype Oranienburg reveals similar virulence, regardless of isolation years and sources.

Salmonella enterica serotype Oranienburg is a multi-host, ubiquitous, and prevalent Non-typhoidal Salmonella (NTS) in subtropical rivers, particularly in sediments; little studied so far possible the adaptation and establishment of this microorganism based on its genetic content. This study was focused on the first five genomes of S. Oranienburg in sediments through whole-genome sequencing (WGS) and 61 river water genomes isolated in previous studies.

Prevalence and Genomic Diversity of Recovered from River Water in a Major Agricultural Region in Northwestern Mexico.

is a leading cause of human gastrointestinal disease worldwide. Given that is persistent in aquatic environments, this study examined the prevalence, levels and genotypic diversity of isolates recovered from major rivers in an important agricultural region in northwestern Mexico. During a 13-month period, a total of 143 river water samples were collected and subjected to size-exclusion ultrafiltration, followed by enrichment, and selective media for isolation and quantitation.

Genomic and biological characterization of the novel phages vB_VpaP_AL-1 and vB_VpaS_AL-2 infecting Vibrio parahaemolyticus associated with acute hepatopancreatic necrosis disease (AHPND).

Acute hepatopancreatic necrosis disease (AHPND) is a life-threatening disease to recently stocked shrimp. This disease is mainly caused by Vibrio parahaemolyticus and, to date, it has not been effectively controlled. Bacteriophages are a promising method to control bacterial diseases in aquaculture and multiple phages that infect Asian strains of V.

Metabolic plasticity of as adaptation strategy in river water.

The survival of in subtropical river water depends on genetic and metabolic reorganization for the expression of alternative metabolic pathways in response to starvation, which allows to use environmental carbon sources (C-sources). However, knowledge regarding the metabolic plasticity of serotypes for C-source utilization when exposed to these conditions remains unclear. The aim of this study was to evaluate the metabolic response and level of environmental C-source consumption by environmental (Oranienburg and Saintpaul) and clinical (Typhi) serotypes by comparing laboratory growth against exposure to river water conditions.
