Immunogenicity of R factor-carrying Salmonella.
An increased frequency of rough cultures with associated reductions in mouse virulence was detected after R-factor transmission into strains of Salmonella choleraesuis var. kunzendorf and S. typhimurium. All rough strains tested, with or without R factors, conferred protective immunity against challenge with homologous or heterologous species of Salmonella, some of which contained R factors. Al...
متن کاملImmunogenicity of recombinant attenuated Salmonella enterica serovar Typhimurium vaccine strains carrying a gene that encodes Eimeria tenella antigen SO7.
Recombinant attenuated Salmonella vaccines against avian coccidiosis were developed to deliver Eimeria species antigens to the lymphoid tissues of chickens via the type 3 secretion system (T3SS) and the type 2 secretion system (T2SS) of Salmonella. For antigen delivery via the T3SS, the Eimeria tenella gene encoding sporozoite antigen SO7 was cloned downstream of the translocation domain of the...

15 صفحه اولIsolation of kanamycin and paromamine inactivated by E. coli carrying R factor.
Kanamycin and paromamine were inactivated in the presence of ATP and Mg++ by an enzyme solution obtained from E. coli carrying R factor. The inactivated kanamycin was isolated and it was found that the hydroxyl group on C-3 of 6-amino-6-deoxy-D-glucose moiety was phosphorylated. In the inactivated paromamine, the hydroxyl group on C-3 of D-glucosamine moiety was phosphorylated. Besides the inac...
متن کاملCharacteristics and expression of tetracycline resistance in gram-negative bacteria carrying the Pseudomonas R factor RP1.
The Pseudomonas R factor RP1 determines an inducible tetracycline resistance similar to that described for Escherichia coli R factors. The level of RP1-determined resistance measured by minimal inhibitory concentration testing is dependent on the host bacteria and corresponds to the magnitude of decrease in tetracycline accumulation by RP1-containing organisms. The tetracycline resistance mecha...
