Distribution of blaCTX-M-gene variants in E. coli from different origins in Ecuador

This study examines blaCTX-M gene variants in E. coli from chicken and human sources in Ecuador, finding greater similarity between isolates from a rural community and suggesting potential gene transfer between chickens and humans.

A Longitudinal Study of Dominant E. coli Lineages and Antimicrobial Resistance in the Gut of Children Living in an Upper Middle-income Country

This study tracks E. coli lineages and antimicrobial resistance in children's gut over a year, finding dominant strains are transient and resistance patterns vary without clear selective pressure.

Effect of diet modification in intestinal Escherichia coli population and antimicrobial resistance

This study examines how diet changes affect E. coli lineage composition and antimicrobial resistance in chickens, finding no differences in resistance profiles between diets.

A longitudinal study of E. coli lineages and antimicrobial resistance in Ecuadorian children

This study tracks E. coli lineages and antimicrobial resistance in Ecuadorian children over a year, finding that most lineages are transient but some resistant strains persist for months.

Salmonella grows massively and aerobically in fecal matter

This study shows Salmonella and E. coli grow significantly in chicken fecal matter under aerobic conditions over 72 hours, suggesting aerobic treatments may not effectively reduce Salmonella in the environment.

Withdraw of prophylactic antimicrobials does not change the pigs’ resistome

This study finds that withdrawing prophylactic antimicrobials from pigs does not change the resistome, suggesting fitness costs of antimicrobial resistance may be overestimated.

The evolutionary dynamics of Oropouche Virus (OROV) in South America

This study analyzes the evolutionary dynamics of Oropouche Virus in South America using genomic data to identify evolutionary processes and structural features.

Diverse commensal E. coli clones and plasmids disseminate antimicrobial resistance genes in domestic animals and children in a semi-rural community in Ecuador

This study identifies diverse plasmids and nonclonal dissemination of antimicrobial resistance genes among E. coli isolates from humans and domestic animals in a semi-rural Ecuadorian community.

Evolutionary changes of an intestinal Lactobacillus reuteri during probiotic manufacture

This study shows that repeated growth of Lactobacillus reuteri in milk reduces its ability to grow in culture media and possibly colonize the mammalian intestine.

Diverse Escherichia coli lineages, from domestic animals and humans in a household, carry colistin resistance gene mcr-1 in Ecuador

The study identifies mcr-1 gene in E. coli from domestic animals and humans in a household, showing horizontal gene transfer between different E. coli lineages.

Soil Protists in Three Neotropical Rainforests are Hyperdiverse and Dominated by Parasites

The paper investigates protist diversity in Neotropical rainforest soils, finding them hyperdiverse and dominated by parasitic Apicomplexa, which may influence animal diversity.
