Effect of SE Dose on Egg Transfer

Jan 8, 2013

Dr. Richard Gast of the Egg Safety and Quality Research Unit USDA-ARS Russell Research Institute in Athens Georgia recently published on the infectivity of SE under experimental conditions*. A slide presentation with commentary on this topic was posted on EGG-CITE on October 29th 2012 under the “Presentations” tab.

A number of publications contributing to our understanding of the epidemiology of SE are based on previous papers authored by Dr. Gast and his research team.  A significant question raised relates to the oral dose in relation to vertical transmission.  Previously high doses, in the region of 107 to 108 were administered to hens to study infectivity.
