Recent studies have established the importance of neutrophils in innate resistance to Listeria monocytogenes infection in mice. The purpose of this study was to determine the importance of neutrophils in acquired resistance to L. monocytogenes infection. Previously immunized mice that were depleted of neutrophils by administration of the antigranulocyte(More)
Johne's disease, caused by Mycobacterium paratuberculosis infection, is a worldwide problem for the dairy industry and has a possible involvement in Crohn's disease in humans. To identify virulence determinants of this economically important pathogen, a library of 5,060 transposon mutants was constructed using Tn5367 insertion mutagenesis, followed by(More)
Mice injected i.p. with RB6-8C5 mAb experienced a profound depletion of neutrophils in the bloodstream and spleen and significant impairment of their resistance to experimental infection with Listeria monocytogenes. Control mice survived i.v. inoculation with 5 x 10(4) L. monocytogenes; whereas, most RB6-8C5 mAb-treated mice inoculated i.v. with as few as(More)
Listeriosis is an important food-borne disease that causes high rates of morbidity and mortality. For reasons that are not clear, most large outbreaks of human listeriosis involve Listeria monocytogenes serotype 4b. Relatively little is known about the pathogenesis of listeriosis following gastrointestinal exposure to food-borne disease isolates of L.(More)
Previous research has found high rates of psychiatric disorders among veterans with war zone-related posttraumatic stress disorder (PTSD). However, many studies in this area are methodologically limited in ways that preclude unambiguous interpretation of their results. The purpose of this study was to address some of these limitations to clarify the(More)
Two dogs with osteoma or multilobulated tumor of bone of the skull were treated with large en bloc resections. The resections resulted in exposure of the brain above the horizon line of the remaining calvarium; in 1 dog, the removal of the dorsal orbital rims also exposed both orbits dorsally. Protection of the brain and exposed tissues and restoration of(More)
Conjugated linoleic acid (CLA) has been used experimentally as a dietary supplement to increase lean body weight and to modulate inflammation in a variety of animal species. In addition, human use of dietary CLA as a supplement to regulate body fat has received both scientific and public attention. No reports have been published regarding the effects of(More)
