chronic salmonella infected mouse model

El modelo de ratón infectado de bacterias es un sistema poderoso modelo para el estudio de áreas tales como infección, inflamación, la inmunología, la transducción de señales y tumorigénesis. Muchos investigadores han tomado ventaja de la colitis inducida por<em&gt; Salmonella</em&gt; Typhimurium para los estudios en la fase temprana de la inflamación y la infección. Sin embargo, sólo unos pocos informes se encuentran en la infección crónica<em&gt; In vivo</em&gt;. Los ratones con<em&gt; Salmonella</emExistencia&gt; persistente en el tracto gastrointestinal nos permiten explorar el anfitrión-bacterial interacción a largo plazo, la transducción de señales y tumorigénesis. Hemos establecido un modelo de crónica bacteriana ratones infectados con el<em&gt; Salmonella</em&gt; Typhimurium colonización en el intestino del ratón más de 6 meses. Para utilizar este sistema, es necesario que el investigador para aprender a preparar el cultivo de bacterias y alimentación forzada de los animales. Se detalla una metodología para el cultivo de bacterias y preparar a los ratones por sonda nasogástrica. También muestra la forma de detectar la<em&gt; Salmonella</em&gt; Persistencia en el tracto gastrointestinal. En términos generales, este protocolo ayudará a los investigadores con el modelo de ratón infectado de bacterias para hacer frente a cuestiones biológicas y microbiológicas de fundamental importancia.
