Transgenic lettuce seedlings carrying hepatitis B virus antigen HBsAg
(Brazilian Society of Infectious Diseases, 2008-12-01)
The obtainment of transgenic edible plants carrying recombinant antigens is a desired issue in search for economic alternatives viewing vaccine production. Here we report a strategy for genetic transformation of lettuce ...
Immune response and functional role of antibodies raised in heifers against a Staphylococcus aureus CP5 lysate and recombinant antigens vaccine formulated with Iscom Matrix adjuvant
Staphylococcus aureus is the most frequently isolated pathogen from bovine intramammary infections worldwide. Commercially available vaccines for mastitis control are composed either of S. aureus lysates or inactivated ...
Recombinant K28 antigen in ELISA in the diagnosis of canine visceral leishmaniosis
Crude total antigen (CTA) from Leishmania infantum and recombinant antigen K39 (rK39) and recombinant antigen K28 (rK28) were compared using an ELISA for the diagnosis of canine visceral leishmaniosis (CVL). Forty-two blood ...
Serological diagnosis of Chagas disease with purified and defined Trypanosoma cruzi antigens
(Instituto Oswaldo Cruz, Ministério da Saúde, 1999-09-01)
Recombinant lactic acid bacteria as delivery vectors of heterologous antigens: the future of vaccination?
Lactic acid bacteria (LABs) are good candidates for the development of new oral vaccines and are attractive alternatives to attenuated pathogens. This review focuses on the use of wild-type and recombinant lactococci and ...
Fetal IgG specificities against Trypanosoma cruzi antigens in infected newborns
(National Academy of Sciences, 1990)
A panel of Trypanosoma cruzi antigens produced by recombinant DNA techniques was used to analyze the IgM and IgG specificities present in sera from 22 mothers with chronic Chagas disease and their newborn infants. Ten ...
Stable expression of Leptospira interrogans antigens in auxotrophic Mycobacterium bovis BCG
(Sociedad de Biología de Chile, 2010)
A recombinant multi-antigen vaccine formulation containing Babesia bovis merozoite surface antigens MSA-2a1, MSA-2b and MSA-2c elicits invasion-inhibitory antibodies and IFN-γ producing cells
(BioMed Central, 2016)
Abstract Background Babesia bovis is a tick-transmitted protozoan hemoparasite and the causative agent of bovine babesiosis, a potential risk ...
Recombinant protein- and synthetic peptide-based immunoblot test for diagnosis of neurocysticercosis
(American Society for Microbiology, 2014)
One of the most well-characterized tests for diagnosing neurocysticercosis (NCC) is the enzyme-linked immunoelectrotransfer blot (EITB) assay developed at the CDC, which uses lentil lectin-bound glycoproteins (LLGP) extracted ...
Origins of sequence diversity in the malaria vaccine candidate merozoite surface protein-2 (MSP-2) in Amazonian isolates of Plasmodium falciparum
(Elsevier B.V., 2006-07-19)
The recent evolution of Plasmodium falciparum is at odds with the extensive polymorphism found in most genes coding for antigens. Here, we examined the patterns and putative mechanisms of sequence diversification in the ...
