We conducted studies with mice, rats, and monkeys which demonstrated the ability of glucan to induce either nonspecific or specific enhancement of host resistance to infectious diseases. Intravenous pretreatment of mice with glucan significantly enhanced the survival of mice challenged with either Venezuelan equine encephalomyelitis (VEE) virus or Rift(More)
Live, attenuated strains of Bacillus anthracis lacking either the capsule plasmid pXO2, the toxin plasmid pXO1, or both were tested for their efficacy as vaccines against intravenous challenge with anthrax toxin in Fischer 344 rats and against aerosol or intramuscular challenge with virulent anthrax spores in Hartley guinea pigs. Animals immunized with(More)
Mice were vaccinated intranasally (i.n.) or with small-particle aerosols (SPA; 2 mum) or large-particle aerosols (LPA; 8 mum) of an attenuated, temperature-sensitive, recombinant A influenza (H3N2) virus, ts-1 (E). Serum virus-neutralizing and hemagglutination inhibition antibodies were detected for all vaccinated mice by 28 days. Bronchoalveolar wash(More)
Fischer 344 rats were given the attenuated live vaccine strain of Francisella tularensis by small-particle aerosol, intranasal instillation, or intraperitoneal, intramuscular, or subcutaneous injection. All of the vaccinated rats developed subclinical infection by 3 days after exposure, which cleared by day 28. Temporal patterns and concentrations of the(More)
The distribution of Mycoplasma pneumoniae infection in the respiratory tract and the extent of pulmonary pathology were determined by the site of deposition and the number of organisms administered to hamsters. Infection of the upper and lower areas of the respiratory tract occurred when organisms were introduced into both areas by small-particle aerosol(More)
The results obtained in this study indicate that serum protease is not activated by either a rabbit or guinea pig antiovalbumin-ovalbumin system, in vitro. A precipitin reaction occurring in the presence of a serum protease precursor of three species (human, rabbit, and guinea pig) failed to activate the protease precursor. Furthermore, particulate material(More)
