The relationship between the in vitro antibacterial activity of carbenicillin in the presence of leukocytes and the therapeutic efficacy of the antibiotic against experimental infection in animals was investigated. Proteus mirabilis strains 3 and 60 were selected as the test strains. The susceptibility of these strains to carbenicillin was similar in the conventional broth medium, but differed ...

Groups of CD-1 mice were immunized with vaccines prepared from freeze-thawed or ultra-sonicated epimastigotes, blood trypomastigotes, or "plasma antigen", of Trypanosoma cruzi strains Y, M1 and Tulahuen. The mice were challenged by the injection of blood stream trypomastigotes obtained from mice, or of metacyclic trypomastigotes harvested from the rectum of Rhodnius prolixus. Both challenges in...
