Autor: Christopher R. Gregory, Kenneth S. Latimer, Niraj K. Tripathi, Richard E. Wooley, Branson W. Ritchie, Randal L. Walker

Publikováno v: Journal of Veterinary Diagnostic Investigation. 17:45-54

A reproducible, experimental model of columnaris disease was developed to study the pathogenesis of cutaneous disease associated with Flavobacterium columnare infection in koi ( Cyprinus carpio). In experimental infections, lesions were usually restr

Comparison of Several Challenge Models for Studies in Avian Colibacillosis

Autor: Shana R. Petermann, Penelope S. Gibbs, Richard E. Wooley

Publikováno v: Avian Diseases. 48:751-758

In previous studies, the embryo lethality assay (ELA) discriminated between virulent and avirulent avian Escherichia coli isolates, and also proved to be highly correlated with mortality and morbidity results of the intravenous (IV) challenge model.

Virulence Factors Associated with Escherichia coli Present in a Commercially Produced Competitive Exclusion Product

Autor: Penelope S. Gibbs, Richard E. Wooley, John J. Maurer, Charles L. Hofacre, Robrecht Froyman

Publikováno v: Avian Diseases. 46:704-707

In this study, we assessed the pathogenic potential of Escherichia coli associated with a commercial competitive exclusion (CE) product by examining the phenotypic characteristics associated with E. coli virulent for humans and domestic animals. Most

Avian colibacillosis is a costly disease for the poultry industry. The mechanisms of virulence employed by the etiologic agent of this disease remain ill defined. However, accumulated evidence suggests that complement resistance and the presence of t

Complement Resistance, as Determined by Viable Count and Flow Cytometric Methods, and Its Association with the Presence of iss and the Virulence of Avian Escherichia coli

Autor: Catherine W. Giddings, Curt Doetkott, Penelope S. Gibbs, Steven L. Foley, Shelley M. Horne, Richard E. Wooley, Lisa K. Nolan

Publikováno v: Avian Diseases. 46:386-392

Previous work in our labs has shown that avian Escherichia coli virulence is correlated with resistance to complement. Also, our studies have revealed that the presence of the increased serum survival gene (iss), known to contribute to the complement

Antimicrobial effect of combinations of EDTA-Tris and amikacin or neomycin on the microorganisms associated with otitis externa in dogs

Autor: Richard E. Wooley, D. T. Kemp, P. S. Gibbs, T. A. Sparks

Publikováno v: Veterinary Research Communications. 18:241-249

Combinations of EDTA-Tris and two aminoglycoside antibiotics (amikacin and neomycin) were tested for synergistic activities against the microorganisms associated with otitis externa in dogs and for the solutions' stability over time. Synergistic acti

Autor: Patrick, Hensel, Michaela, Austel, Richard E, Wooley, Deborah, Keys, Branson W, Ritchie

Publikováno v: Veterinary dermatology. 20(5-6)

This study assessed the in vitro and in vivo activity of an ear solution containing a third-generation chelating agent (Tricide) as an antimicrobial potentiator for miconazole in chronic Malassezia otitis. Thirty-one ears from 20 dogs were enrolled i
