Pathogenic diversification of the gut commensal via acquisition of a second type III secretion system.

is a Gram-negative bacterium found in various water and land environments and organisms, including insects and mammals. Some strains encode gene homologs of virulence factors found in pathogenic Enterobacterales members, such as serovar Typhimurium and . Whether these genes are pathogenic determinants in is not known.

Pathogenic diversification of the gut commensal via acquisition of a second type III secretion system.

is a Gram-negative bacterium found in a wide variety of water and land environments and organisms. It has been isolated as part of the gut microbiome of animals and insects, as well as from stool samples of patients with diarrhea. Specific strains encode gene homologs of virulence factors found in other pathogenic members of the same Enterobacterales order, such as serovar Typhimurium and Whether these genes are also pathogenic determinants in is not known.

Investigating the Effects of Discrimination Experiences on Everyday Metamemory Accuracy.

Objectives: Lifetime and daily experiences of discrimination contribute to impaired performance on cognitive assessments. However, the underlying mechanism by which discrimination negatively affects cognition is unclear. Recent research investigating stress-induced impairment of metamemory may address the relationship between discrimination experiences and cognitive impairment.

Maternal Sleep Health, Social Support, and Distress: A Mixed-Methods Analysis of Mothers of Infants and Young Children in Rural US.

Objectives: The purpose of this study was to explore sleep health in rural maternal populations through a social-ecological framework and identify risk and protective factors for this population.

Methods: 39 individuals who are mothers of infants or children under the age of 5 years completed an online survey, 35 of which completed a subsequent semi-structured interview. Recruitment was limited to one rural community and was in partnership with community healthcare providers.
