Escherichia coli productora de toxina Shiga: el desafío de adherirse para sobrevivir

las superficies que están en contacto con ellos. Este mecanismo presenta una alta variabilidad intra e interserotipo y su desarrollo no depende solo de los microorganismos que lo conforman. Factores inherentes al ambiente (pH, temperatura) y la superficie (acero inoxidable, poliestireno) a la que pueden adherirse influyen en la expresión de biofilm . El concepto « una salud » implica la interrelación entre los actores de salud pública, animal y ambiental para lograr alimentos inocuos y evitar contaminación cruzada y resistencia a sanitizantes, lo cual pone de manifiesto la necesidad de identificar patógenos emergentes a través de nuevos marcadores moleculares, que detecten cepas STEC portadoras del denominado locus for enterocyte effacement (LEE) o del locus de adherencia y autoagregación (LAA)
