Francisco Denis Souza Santos,Arianna Mazzoli,Ana Raquel Maia,Anella Saggese,Rachele Isticato,Fábio Renato Manzolli Leite,Susanna Iossa,Ezio Ricca,Loredana Baccigalupi +8 more
TL;DR: Results indicate that B. toyonensis spores significantly contribute to the humoral and cellular responses elicited by a mucosal immunization with spore-adsorbed TTFC, pointing to the probiotic treatment as an alternative to the use of adjuvants for mucosal vaccinations.
Journal ArticleDOI

Ana Paula de Souza Stori de Lara,Lucas Bigolin Lorenzon,Ana Muñoz Vianna,Francisco Denis Souza Santos,Luciano da Silva Pinto,Maria Elisabeth Aires Berne,Fábio Pereira Leivas Leite +6 more
TL;DR: The results suggest that the Cry11Aa toxin of B. thuringiensis var.
Journal ArticleDOI
Bacillus toyonensis improves immune response in the mice vaccinated with recombinant antigen of bovine herpesvirus type 5.
Francisco Denis Souza Santos,Y.A. Menegon,Renan Eugênio Araujo Piraine,Paulo Ricardo Centeno Rodrigues,Rodrigo Casquero Cunha,F P Leivas Leite +5 more
TL;DR: The results show that the use of this probiotic may significantly contribute to the response elicited by recombinant vaccines, especially those that rely on increasing antibody and cell-mediated immune responses for efficacy.
Journal ArticleDOI

Mariangela F. Silveira,Marilia Arndt Mesenburg,Odir Antônio Dellagostin,Natasha Rodrigues de Oliveira,Mara Andrade Colares Maia,Francisco Denis Souza Santos,Andre M. Vale,Aluísio J D Barros,Luis Paulo Vidaletti,Fernando C. Barros,Pedro C. Hallal,Bernardo L. Horta,Ana M. B. Menezes,Gabriel D. Victora,Cesar G. Victora +14 more
TL;DR: Whereas the ELISA test showed high sensitivity and stability of results over the five months of the study, both batches of the rapid test showed substantial declines, with one of the batches consistently showing lower sensitivity levels than the other.
Journal ArticleDOI
Immunomodulatory effect of short-term supplementation with Bacillus toyonensis BCT-7112T and Saccharomyces boulardii CNCM I-745 in sheep vaccinated with Clostridium chauvoei.
