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

X. Valenzuela, H. Hedman, A. Villagomez, P. A. Cardenas, J. Eisenberg, K. Levy, L. Zhang, G. Trueba

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

G. Trueba, D. Calderon, P. A. Cardenas, M. B. Prado, J. Graham

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.

Evolutionary changes of an intestinal Lactobacillus reuteri during probiotic manufacture

L. Lopez, P. A. Cardenas, M. B. Prado, G. Trueba

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.
