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.

Genotypic and phenotypic characterization of isolates from periprosthetic joint infections.

Unlabelled: Over 2.5 million prosthetic joint implantation surgeries occur annually in the United States. Periprosthetic joint infections (PJIs), though occurring in only 1-2% of patients receiving replacement joints, are challenging to diagnose and treat and are associated with significant morbidity.

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.

Phospholipid Scramblase 1 Controls Efficient Neurotransmission and Synaptic Vesicle Retrieval at Cerebellar Synapses.

Phospholipids (PLs) are asymmetrically distributed at the plasma membrane. This asymmetric lipid distribution is transiently altered during calcium-regulated exocytosis, but the impact of this transient remodeling on presynaptic function is currently unknown. As phospholipid scramblase 1 (PLSCR1) randomizes PL distribution between the two leaflets of the plasma membrane in response to calcium activation, we set out to determine its role in neurotransmission.
