Article Synopsis
- Leclercia adecarboxylata, although traditionally considered non-pathogenic, is increasingly recognized as a potential pathogen due to its emerging resistance traits, particularly encoded by the fosA gene.* -
- The study analyzed 16 strains of L. adecarboxylata from blood cultures and total parenteral nutrition, using various genomic and phenotypic methods to assess their virulence and resistance characteristics.* -
- Results indicated a significant pathogenic potential and the presence of multiple resistance genes, highlighting concerns about its role in outbreaks related to parenteral nutrition in Mexican public hospitals.*
Introduction: In Mexico, HIV genotyping is performed in people living with HIV (PLWH) failing their first-line antiretroviral (ARV) regimen; it is not routinely done for all treatment-naive PLWH before ARV initiation. The first nationally representative survey published in 2016 reported that the prevalence of pretreatment drug mutations in treatment-naive Mexican PLWH was 15.5% to any antiretroviral drug and 10.

- COVID-19, caused by the SARS-CoV-2 virus, presents a range of symptoms, from no symptoms to severe illness or death, with age and pre-existing conditions being key factors in severity.
- A study in Mexico analyzed 57 complete SARS-CoV-2 genomes from patients under 60 without pre-existing conditions to explore relationships between viral genetics and disease severity.
- The research found greater genomic diversity in the viruses compared to earlier strains and identified numerous mutations, but did not link specific mutations to disease outcomes, suggesting that severity is more influenced by patient genetics and demographics.
Article Synopsis
- The COVID-19 pandemic has impacted countries worldwide, necessitating the study of how the virus evolves and spreads to improve control measures.
- Researchers analyzed the genome sequences of 17 early SARS-CoV-2 cases in Mexico, revealing two main viral lineages from North America and Europe, along with 14 distinct introduction events.
- Findings indicated early local transmission in Mexico by mid-March 2020, featuring a genetic mutation in the Spike protein that could help track further viral spread in the region.
