Protection against Leishmania major challenge infection in mice vaccinated with live recombinant parasites expressing a cytotoxic gene.
A "suicide" system based on thymidine kinase-ganciclovir combination was developed and tested in a Leishmania major experimental model. Susceptible BALB/c mice were infected with L. major expressing the thymidine kinase gene of herpes simplex virus type 1 and treated for 2 consecutive weeks with 7.5 mg/kg/day ganciclovir at different times from the initial infection. Ganciclovir treatment at va...
متن کاملImmunization of mice and calves against Salmonella dublin with attenuated live and inactivated vaccines.
Previous findings, viz. that mice can be successfully immunized against infection with Salmonella dublin with either live or inactivated vaccine, were confirmed. Immunity lasted for at least 12 weeks in mice which had been immunized with inactivated alum-precipitated vaccine. The immunogenicity of inactivated vaccine gradually decreased on storage at 4 degrees C, but this was only detectable if...
متن کاملImmunization of mice and guinea-pigs against Salmonella dublin infection with live and inactivated vaccine.
The immunogenicity of a number of avirulent rough Salmonella dublin mutants was compared in mice and guinea-pigs. Live vaccine prepared from Strain HB 1/17 at doses of 5 X 10(7) per mouse usually gave an immunity of between 70 and 80% but in certain experiments the results were more variable and always poorer. This strain gave a cross protection of 28,5% to S. typhimurium in mice. In guinea-pig...
متن کاملVaccination with Live Attenuated L. Major and TLR4 Agonist Promotes a Th1 Immune Response and Induces Protection against L. Major Infection in BALB/c Mice
Background: Toll like receptors play a major role in immune responses against Leishmania parasites. Objective: To evaluate the efficacy of vaccination with live attenuated L. major and TLR4 agonist in protection against L. major infection. Methods: Attenuated L. major was prepared by continuous sub-culturing of the parasite. A total of 90 mice were assigned to 9 groups including 6 groups of BAL...
متن کاملPassive protection of mice against intraperitoneally injected Vibrio cholerae by G and M antibody.
Fractions of rabbit anti-Vibrio cholerae serum containing gammaG antibodies were compared with fractions containing gammaM antibodies for their ability to protect mice against lethal infection resulting from the intraperitoneal injection of organisms suspended in mucin. About twice as much gammaG as gammaM (estimated by quantitative precipitation) was required to protect against approximately 1...
