Explorando la presencia de la isla genómica PKS mediante anticuerpos específicos dirigidos a la maquinaria productora de colibactina

Abstract

Escherichia coli es una de los primeros colonizadores del intestino humano, normalmente las cepas pertenecientes a esta especie son comensales incluso algunas de ellas han sido seleccionadas como probióticos. Sin embargo, algunas cepas llevan consigo las llamadas islas de patogenicidad o diferentes elementos móviles que están asociados con enfermedades intra- y extra- intestinales. La isla genómica pks codifica la maquinaria necesaria para la síntesis de una genotoxina híbrida péptido-poliquétido llamada colibactina. La colibactina induce roturas de doble cadena en el ADN, aberraciones cromosómicas y detección del ciclo celular. La cepa probiótica Nissle 1917, contiene la isla pks y produce una genotoxina funcional. Recientes estudios han encontrado la isla de patogenicidad en otros miembros de la familia Enterobacteriaceae, tales como Citrobacter, Klebsiella y Enterobacter. El objetivo principal de este estudio fue realizar un análisis a gran escala para detectar cepas pks+ de E. coli utilizando la citometría de flujo.
