-
Defined the natural occurrence and shedding patterns of
E. coli O157:H7 in cattle herds and in local and regional farm environments
-
First recognized
Salmonella Typhimurium DT 104 as an emerging and
zoonotic pathogen in the USA
-
Demonstrated contamination of feedstuffs and water sources as
important factors in dissemination of zoonotic pathogens and normal
flora with antimicrobial resistance
-
Selected as a Zoonosis Research Unit within the NIH Food and
Waterborne Disease Integrated Research Network
-
Built solid collaborations among WSU research faculty, the Washington
Animal Disease Diagnostic Laboratory, and the Washington Department of
Health to promote animal and public health
