chronic salmonella infected mouse model

O modelo do rato infectado de bactérias é um sistema poderoso modelo para o estudo de áreas tais como inflamação, infecção, imunologia, transdução de sinal, e tumorigênese. Muitos pesquisadores têm se aproveitado da colite induzida por<em&gt; Salmonella</em&gt; Typhimurium para os estudos sobre a fase inicial de inflamação e infecção. No entanto, poucos relatos são a infecção crônica<em&gt; In vivo</em&gt;. Camundongos com<em&gt; Salmonella</em&gt; Existência persistente no trato gastrointestinal nos permitem explorar a host-bacteriana interação a longo prazo, transdução de sinal, e tumorigênese. Nós estabelecemos um modelo de camundongo bacteriana crônica infectados com<em&gt; Salmonella</em&gt; Typhimurium colonização no intestino do rato mais de 6 meses. Para utilizar este sistema, é necessário que o pesquisador para aprender a preparar a cultura bacteriana e sonda os animais. Detalhamos uma metodologia para cultura bacteriana preparar e ratos gavagem. Também mostramos como detectar a<em&gt; Salmonella</em&gt; Persistência no trato gastrointestinal. Globalmente, este protocolo vai ajudar os pesquisadores usando o modelo de camundongo infectado de bactérias para tratar fundamentalmente importantes questões biológicas e microbiológicas.
