chronic salmonella infected mouse model

Le modèle de souris infectées par des bactéries est un système puissant modèle pour étudier des domaines tels que l&#39;infection, l&#39;inflammation, l&#39;immunologie, la transduction du signal, et la tumorigenèse. De nombreux chercheurs ont tiré parti de la colite induite par<em&gt; Salmonella</emTyphimurium&gt; pour les études sur la phase précoce de l&#39;inflammation et l&#39;infection. Cependant, seuls quelques rapports sont sur l&#39;infection chronique<em&gt; In vivo</em&gt;. Souris avec<em&gt; Salmonella</emL&#39;existence&gt; persistante dans le tractus gastro-intestinal nous permettent d&#39;explorer la relation hôte-bactérienne à long terme d&#39;interaction, la transduction du signal, et la tumorigenèse. Nous avons établi un modèle de chroniques bactériennes de souris infectées par<em&gt; Salmonella</emLa colonisation typhimurium&gt; dans l&#39;intestin de la souris sur 6 mois. Pour utiliser ce système, il est nécessaire pour le chercheur d&#39;apprendre à préparer la culture bactérienne et gavage des animaux. Nous détaillons une méthode pour préparer des cultures bactériennes et des souris par gavage. Nous montrons aussi comment détecter la<em&gt; Salmonella</emLa persistance&gt; dans le tractus gastro-intestinal. Globalement, ce protocole aidera les chercheurs utilisant le modèle de souris infectées par des bactéries pour traiter des questions d&#39;importance fondamentale biologiques et microbiologiques.
