We describe an acute human immunodeficiency virus (HIV) infection in 16 homosexual men who presented with painful swallowing (odynophagia). Eleven men had a maculopapular rash and 3 had palatal ulcers. At esophagogastroduodenoscopy (endoscopy), multiple discrete esophageal ulcers measuring 0.3 to 1.5 cm in diameter were observed. Electron microscopy of(More)

Methisazone 40 mg/kg/day was administered orally to six pediatric and one adult patient who contracted vesicular complications affecting the skin or mucocutaneous junctions 3 to 9 days after antismallpox vaccination, and to one elderly man with myeloid leukemia who developed vaccinia necrosum. Therapy was commenced 2 to 10 days after onset of complications(More)
With a wide host range vector, the structural gene aerA for the hole-forming extracellular protein aerolysin of Aeromonas hydrophila was cloned into the marine Vibrio sp. strain 60 and into three pleiotropic export mutants (epr mutants). The parent strain and all of the mutants were able to express the protein with the aerA promoter in the plasmid. The(More)
California encephalitis (CE) virus (snowshoe hare subtype) was isolated from 1 of 38 pools comprising 970 unengorged female Aedes canadensis mosquitoes and from 3 of 152 pools containing 5,676 A. communis mosquitoes which were collected in the Yukon Territory, Canada between latitudes 61 and 66 degrees N during June and July 1974. During four summers 1971(More)
Strains of California encephalitis virus (snowshoe hare subtype) were isolated from 8 of 475 pools comprising 23 747 unengorged female mosquitoes of five species collected at three of six locations throughout the Mackenzie Valley of the Northwest Territories, Canada, from latitudes 60 to 69 degrees N between 10 and 24 July 1976.

Eight homosexual men presented with odynophagia. Five had a maculopapular rash and 2 had oral ulcers. Upper panendoscopy revealed the presence of multiple discrete ulcers measuring 3 mm-1.5 cm in diameter in the esophagus of each patient. The intervening mucosa appeared normal. Endoscopic brushings and biopsy specimens taken from the ulcer margins and(More)
Replication of a subarctic Bunyavirus, California encephalitis (snowshoe hare subtype), was detected in salivary glands and thoraces of wild-caught Aedes communis mosquitoes from the Yokon Territory, after intrathoracic inoculation with 0.1 to 100 mouse LD50 virus, and incubation for 7 to 21 days throughout their viable temperature range of 0 to 23 degrees(More)
