Enteritidis Outbreaks Associated with Egg-Producing Farms Not Regulated by Food and Drug Administration's Egg Safety Rule.

The Food and Drug Administration Egg Safety Rule requires producers with >3000 layer hens to register a serotype Enteritidis (SE) prevention plan for production, storage, and transport of shell eggs. Since its implementation began in 2010, four outbreaks of egg-associated salmonellosis have occurred in Tennessee. We reviewed state health department records from each outbreak and described them in the context of the Egg Safety Rule.

Pet Ownership and Quality of Life: A Systematic Review of the Literature.

Pet ownership is the most common form of human-animal interaction, and anecdotally, pet ownership can lead to improved physical and mental health for owners. However, scant research is available validating these claims. This study aimed to review the recent peer reviewed literature to better describe the body of knowledge surrounding the relationship between pet ownership and mental health.

Effect of Mare Age on Transcript Abundance of Connexins-37 and -43, Zona Pellucida Proteins, and Sperm Binding.

Zona pellucida (ZP) proteins are important for fertilization and sperm binding and are closely associated with cumulus cells. Communication between cumulus and oocytes is facilitated by intracellular membrane channels composed of connexins. The extent aging impacts potential differences in fertilization and reductions in fertility is not well understood.
