These experiments determined the ability of Escherichia coli O157:H7 to colonize and persist in pigs simultaneously inoculated with other pathogenic E. coli strains. Three-months-old pigs were inoculated with a mixture of five E. coli strains. The mixture included two Shiga toxigenic E. coli (STEC) O157:H7 strains, two enterotoxigenic E. coli (ETEC) strains(More)
Shiga toxins (Stxs) produced by Escherichia coli (STEC) cause systemic vascular damage, manifested as hemolytic uremic syndrome in humans and as edema disease in pigs. Edema disease, a naturally occurring disease of pigs, was used to determine whether Stx antibodies, administered after infection and after the onset of Stx production, could prevent the(More)
Shiga toxin-producing Escherichia coli (STEC) is an important cause of food-borne illness in humans. Ruminants appear to be more frequently colonized by STEC than are other animals, but the reason(s) for this is unknown. We compared the frequency, magnitude, duration, and transmissibility of colonization of sheep by E. coli O157:H7 to that by other(More)
We conducted a pilot study to evaluate the efficacy of topiramate in trigeminal neuralgia using a randomized, double-blind, placebo-controlled, two-period crossover design. Three patients were enrolled in and completed the study. All three patients responded to topiramate in this main study and entered a subsequent confirmatory study consisting of three(More)
BACKGROUND Previous studies suggest that 2-amino-3-hydroxy-5-methyl-4-isoxazole-proprionic acid (AMPA)/kainate antagonists reduce experimentally induced pain. There have been no studies of AMPA/kainate antagonists in clinical pain. METHODS Analgesic efficacy of intravenous LY293558 (0.4 or 1.2 mg/kg) was compared with that of intravenous ketorolac(More)
BACKGROUND NMDA glutamate receptor antagonists such as ketamine and dextromethorphan reduce pain in certain neuropathic pain conditions. However, there have been no controlled trials of NMDA antagonists in facial neuralgias. METHODS A randomized, double-blind, crossover trial compared 6 weeks of oral dextromethorphan with active placebo (low-dose(More)
