Journal ArticleDOI
Efficacy of several vaccination programmes in commercial layer and broiler breeder hens against experimental challenge with Salmonella enterica serovar Enteritidis
Rafael Antonio Casarin Penha Filho,Jacqueline Boldrin de Paiva,Yuli Melisa Sierra Arguello,Mariana Dias da Silva,Yannick Gardin,Fernando Resende,Angelo Berchieri Junior,Luiz Sesti +7 more
TL;DR: Overall, in both experiments, all vaccination schemes were significantly effective in reducing organ colonization by the challenge strain as well as reducing faecal excretion for at least 3 weeks.
Journal ArticleDOI
Control of Salmonella Enteritidis and Salmonella Gallinarum in birds by using live vaccine candidate containing attenuated Salmonella Gallinarum mutant strain
Rafael Antonio Casarin Penha Filho,Jacqueline Boldrin de Paiva,Mariana Dias da Silva,Adriana Maria de Almeida,Angelo Berchieri Junior +4 more
TL;DR: SG mutant is a promising Salmonella live vaccine candidate that demonstrated good efficacy to control the infection by two serotypes of major importance to the poultry industry.
Journal ArticleDOI
Evaluation and characterization of plasmids carrying CTX-M genes in a non-clonal population of multidrug-resistant Enterobacteriaceae isolated from poultry in Brazil
Joseane Cristina Ferreira,Rafael Antonio Casarin Penha Filho,Leonardo Neves Andrade,Angelo Berchieri Junior,Ana Lúcia da Costa Darini +4 more
TL;DR: Similar resistance elements were disseminated among a diverse population of ESBL-producing enterobacteria in the microbiota of chickens produced in Brazil.
Journal ArticleDOI
Humoral and cellular immune response generated by different vaccine programs before and after Salmonella Enteritidis challenge in chickens.
Rafael Antonio Casarin Penha Filho,Bruna Silva Moura,Adriana Maria de Almeida,Hélio José Montassier,Paul A. Barrow,Angelo Berchieri Junior +5 more
TL;DR: It is demonstrated that the development of a mature immune response by CD8(+) T cells, provided by the use of the LV, had better efficacy in comparison to the high antibody levels in the serum stimulated by the KV.
Journal ArticleDOI
Immunomodulatory activity and control of Salmonella Enteritidis colonization in the intestinal tract of chickens by Lactobacillus based probiotic
Rafael Antonio Casarin Penha Filho,Rafael Antonio Casarin Penha Filho,Silvia Juliana Acelas Diaz,Filipe Santos Fernando,Yung-Fu Chang,Raphael Lucio Andreatti Filho,Angelo Berchieri Junior +6 more
TL;DR: Pretreatment of chicks with LBP decreased the intestinal colonization by Salmonella Enteritidis infection in one-week-old broiler chicks, minimizing the tissue lesions and inflammation after challenge and showed a potential use as adjuvant with injectable killed vaccines.
