Washington State University officials say a $25 million grant from the Bill & Melinda Gates Foundation will help build a new school dedicated to studying infectious diseases affecting animals and humans.

The grant announced today for the university’s School for Global Animal Health is the largest single private gift in WSU history.

Officials say the gift will go toward construction of a $35 million building on the WSU Pullman campus for research focusing on discovering new vaccines, emerging diseases and controlling global infectious diseases.

The largest previous single donation to WSU was a $7 million gift from The Boeing Co. in 1993.
