Protective Immunity in Mice Immunized With MSP1-Based Formulations and Challenged With Expressing MSP1.

The lack of continuous cultures has been an obstacle delaying pre-clinical testing of vaccine formulations based on known antigens. In this study, we generated a model to test available formulations based on the MSP1 antigen. The strains ANKA and NK65 were modified to express MSP1 instead of the endogenous MSP1.

Prime-boost vaccination with recombinant protein and adenovirus-vector expressing Plasmodium vivax circumsporozoite protein (CSP) partially protects mice against Pb/Pv sporozoite challenge.

Vaccine development against Plasmodium vivax malaria lags behind that for Plasmodium falciparum. To narrow this gap, we administered recombinant antigens based on P. vivax circumsporozoite protein (CSP) to mice.

Generation, characterization and immunogenicity of a novel chimeric recombinant protein based on Plasmodium vivax AMA-1 and MSP1.

Plasmodium vivax is the most widely distributed malaria species and the most prevalent species of malaria in America and Asia. Vaccine development against P. vivax is considered a priority in the global program for the eradication of malaria.

Biofilm-producing ability of Listeria monocytogenes isolates from Brazilian cheese processing plants.

The persistence of Listeria monocytogenes in food industry environments has been associated to the ability of specific isolates to produce biofilms. This study aimed to evaluate the biofilm production of 85 L. monocytogenes strains previously isolated from samples of cheese, brine and the environment of two cheese processing plants located in São Paulo, Brazil.
