Variation In Avian Pathogenic Escherichia Coli Colonization Levels In Chickens, Melissa Monson, Michael Kaiser, Susan Lamont
Variation In Avian Pathogenic Escherichia Coli Colonization Levels In Chickens, Melissa Monson, Michael Kaiser, Susan Lamont
Melissa Monson
Colonization levels in five tissues after avian pathogenic Escherichia coli (APEC) inoculation were investigated in chickens to generate phenotypic data for a genome wide association study (GWAS). Bacterial loads were measured in 370 birds and varied among individuals and tissues. Mean bacterial levels were significantly different between tissues (right lung > spleen > left lung and liver > blood). There were also significant correlations in bacterial load between tissues. These data suggest that colonization levels could be used as phenotypes in GWAS and could help identify markers associated with poultry resistance to APEC infections. After verification, these markers could be used for genetic …

Data from eighteen different truck washes were used to compare the association of different service levels with Enterobacteriaceae counts. Service levels were classified into three different categories; prewash (n=78), post wash with disinfectant (n=78), and post wash without disinfectant (n=12). A total of 168 drag swabs were used for collection for the purpose of this study. Prewash services were defined as trailers before they were scraped out and washed. Post wash with or without disinfectant services were defined as after the trailers were washed and disinfectant was or was not applied. Prewash trailers tended to have higher Enterobacteriaceae counts of …
The Human/Animal Interface: Emergence And Resurgence Of Zoonotic Infectious Diseases, Michael Greger
The Human/Animal Interface: Emergence And Resurgence Of Zoonotic Infectious Diseases, Michael Greger
Michael Greger, MD, FACLM
Emerging infectious diseases, most of which are considered zoonotic in origin, continue to exact a significant toll on society. The origins of major human infectious diseases are reviewed and the factors underlying disease emergence explored. Anthropogenic changes, largely in land use and agriculture, are implicated in the apparent increased frequency of emergence and reemergence of zoonoses in recent decades. Special emphasis is placed on the pathogen with likely the greatest zoonotic potential, influenzavirus A.
