Antimicrobial resistance profiles and presence of resistance determinants and integrons were evaluated in Salmonellaenterica strains from Brazilian poultry. The analysis of 203 isolates showed that those from the poultry environment (88 isolates) were significantly more resistant to antimicrobials than isolates from other sources, particularly those isolated from poultry by-product meal (106 isolates). Thirty-seven isolates were resistant to at least three antimicrobial classes.

Environmental enteropathy (EE) is a subclinical enteric condition found in low-income countries that is characterized by intestinal inflammation, reduced intestinal absorption, and gut barrier dysfunction. The researchers aimed to assess if EE impairs the success of oral polio and rotavirus vaccines in infants in Bangladesh.
