Resumo

Introdução: Dados dos Estados Unidos, países europeus e países de baixa e média renda indicam o gênero Salmonella como o patógeno mais comum em alimentos de origem animal. A introdução de agentes antimicrobianos e fagos específicos para Salmonella tem sido considerada uma estratégia de intervenção eficaz para reduzir a contaminação por esse patógeno. Objetivo: Caracterizar a patogenicidade da Salmonella e os mecanismos de escape imunológico à luz das evidências da literatura emergente. Metodologia: Realizou-se uma revisão bibliográfica do tipo integrativa. Foram consultadas as bases de dados de artigos no Google acadêmico, MedLine e Pubmed, com disponibilidade de acesso textual na íntegra. Utilizou-se os descritores: fisiopatologia da Salmonella spp., salmonelose e sistema imune, em pares e isolados, dos quais foram encontrados 209 artigos, destes, foram selecionados 160, usando como critérios de inclusão: textos em inglês, ensaios clínicos e revisões de literatura. Resultados: Sabe-se que o sistema imunológico do hospedeiro é capaz de prevenir com eficácia a invasão microbiana e eliminar microrganismos. No entanto, a Salmonella desenvolveu mecanismos de resistência às barreiras físicas do hospedeiro e inibição da ativação subsequente da resposta imune por meio de seus fatores de patogenicidade. Assim, tem havido um grande interesse em entender como a Salmonella interage com o hospedeiro e como as respostas imunes adaptativas fornecem um feedback positivo para o sistema imune inato, que é mediado pela síntese de citocinas, levando a um aumento do número e ativação de células efetoras e, subsequentemente, produzindo uma resposta antimicrobiana aumentada. Conclusão: Verificou-se a necessidade de novos estudos que expandam a compreensão da interação entre imunidade e bactérias em diferentes órgãos infectados, tendo em vista que a imunidade inata e adaptativa como estratégias de defesa do hospedeiro em seres humanos ainda não está bem definida. Assim, essa revisão teve como foco explicar a relação entre Salmonella e a imunidade do hospedeiro, e evidenciar a melhoraria das estratégias de prevenção e tratamento destinadas a combater essas doenças infecciosas em um futuro próximo.
