Exploring Vaccine Hesitancy Among Parents in a Rural Pediatric Clinic System: A Statistical Study.

Background: Vaccine hesitancy has been a growing concern in the United States, particularly in rural areas where access to healthcare services may be limited. A rural pediatric clinic system in central Louisiana serves a population with historically low childhood immunization rates. This study explored the prevalence and determinants of vaccine hesitancy among parents of pediatric patients at the organization's clinics.

The 1.59Å resolution structure of the minor pseudopilin EpsH of Vibrio cholerae reveals a long flexible loop.

The type II secretion complex exports folded proteins from the periplasm to the extracellular milieu. It is used by the pathogenic bacterium Vibrio cholerae to export several proteins, including its major virulence factor, cholera toxin. The pseudopilus is an essential component of the type II secretion system and likely acts as a piston to push the folded proteins across the outer membrane through the secretin pore.

Expression, purification, crystallization and preliminary X-ray studies of Vibrio cholerae pseudopilin EpsH.

EpsH is a minor pseudopilin protein of the Vibrio cholerae type II secretion system. A truncated form of EpsH with a C-terminal noncleavable His tag was constructed and expressed in Escherichia coli, purified and crystallized by sitting-drop vapor diffusion. A complete data set was collected to 1.
