The secreted colonization factor, TcpF, which is produced by Vibrio cholerae 01 and 0139, has generated interest as a potential protective antigen in the development of a subunit vaccine against cholera. This study evaluated immunogenicity/protective efficacy of a TcpF holotoxin-like chimera (TcpF-A2-CTB) following intraperitoneal immunization compared to TcpF alone, a TcpF+CTB mixture, or CTB ...
Monoclonal antibodies against the highly conserved ubiquitous calcium-binding protein, calmodulin (CaM), were produced by immunization of mouse primary spleen cell cultures. Dissociated spleen cells were cultured for 5 d in the presence of mixed thymocyte culture conditioned media (TCM) and purified bovine testes CaM (50 ng-1 mg). Following immunization, cells were fused with mouse myeloma cell...
We previously demonstrated that immunization of mice with plasmid DNAs (pDNAs) expressing the murine cytomegalovirus (MCMV) genes IE1-pp89 and M84 provided synergistic protection against sublethal viral challenge, while immunization with plasmids expressing putative virion proteins provided no or inconsistent protection. In this report, we sought to augment protection by increasing the breadth ...
The protective effect of therapeutic oral immunization with homologous and heterologous formalin-inactivated Helicobacter pylori cells given together with cholera toxin as an adjuvant was evaluated with C57BL/6 mice infected with H. pylori Sydney strain 1 (SS1). The bacteria used for immunization were strains that were either homologous or heterologous with regard to the O antigen (i.e., the Le...
Staphylococcus aureus is a leading cause of ventricular assist device-related infections. This study evaluated the protective effect against S. aureus infection of active and passive immunization that targeted 3 proteins involved in bacterial attachment to a murine intra-aortic polyurethane patch. Active immunization of mice with a combination of the A domains of clumping factor A (ClfA), fibro...

1. Immunization of rabbits with Type III pneumococci is effective in producing active immunity against infection with a virulent strain of the homologous organism. 2. Immunization of rabbits with Type I or II pneumococci, and with R forms derived from any of the fixed types, is equally effective in producing active immunity against Type III infection. 3. Immunization of rabbits with nucleoprote...
One major pathogenic factor of Porphyromonas gingivalis is Arg-gingipain (Rgp), an arginine-specific cysteine proteinase. To clarify the effect of rgpA DNA vaccine, we immunized BALB/c mice via the abdomen with a Gene Gun or via the nasal cavity weekly for 6 weeks. After immunization, the mice were challenged orally with P. gingivalis. Immunization elicited IgG responses against P. gingivalis i...
BACKGROUND A highly efficacious vaccine is needed for malaria control and eradication. Immunization with Plasmodium falciparum NF54 parasites under chemoprophylaxis (chemoprophylaxis and sporozoite (CPS)-immunization) induces the most efficient long-lasting protection against a homologous parasite. However, parasite genetic diversity is a major hurdle for protection against heterologous strains...
BACKGROUND Vaccine development has been a priority in the fight against leishmaniases, which are vector-borne diseases caused by Leishmania protozoa. Among the different immunization strategies employed to date is inoculation of plasmid DNA coding for parasite antigens, which has a demonstrated ability to induce humoral and cellular immune responses. In this sense, inoculation of plasmid DNA en...
