Antioxidant enzymes are thought to be important for the survival of pathogenic Neisseria species. We isolated a glutathione peroxidase-related gene (gpxA) from Neisseria meningitidis FAM20. The N. meningitidis glutathione peroxidase homolog was 49 to 57% identical to seven other glutathione peroxidase family members over a 49-amino-acid region which is(More)
Comprehensive assessment of the impact of head and neck cancer goes beyond traditional biomedical outcomes to include quality of life. This paper examines the methods used in reported studies on quality of life in head and neck cancer patients with respect to definitions, approaches to measurement, and types of findings. Analysis reveals little consensus in(More)
Previous research indicates that the type and purpose of a virtual community (wiki, blog, and Internet Forum) may play a role in determining a member's motivation for contribution to a virtual community, but does not fully explore this idea. This study aggregates the disparate ideas and terminology of previous research on virtual communities and presents a(More)
Antioxidant enzymes are thought to be important for the survival of pathogenic Neisseria species. We have further characterized the glutathione peroxidase homolog gene (gpxA), which we recently isolated from Neisseria meningitidis FAM20 (T.D.E. Moore and P.F. Sparling, Infect. Immun. 63:1603-1607, 1995). GpxA was found to be produced constitutively in vivo.(More)
A Gram-negative, filamentous, rod-shaped bacillus which failed to grow in cell-free media was isolated in apparently pure culture from the bronchial scraping and washing of a laboratory rat suffering from chronic respiratory disease by inoculating embryonated chicken eggs via the allantoic route. None of the embryos died during 20 serial passages at weekly(More)
In 1969, five cases of melioidosis in three separate outbreaks were diagnosed in nonhuman primates in the United States. In the first outbreak, two stump-tailed macaque monkeys (Macaca arctoides) developed signs of the disease approximately 6 months after purchase. A third animal, a chimpanzee (Pan troglodytes), probably acquired its infection from one of(More)
