Se trata del primer estudio que utiliza animales vivos con cáncer para examinar la posible utilidad de esos microorganismos emisores de luz. Esto ha sido posible ha modificar genéticamente bacterias con el fin de que liberen sustancias químicas luminiscentes. Los autores han observado que distintos microbios son capaces de localizar diferentes tipos de tumores, como el de vejiga o el de mama, e incluso pueden localizar tumores de tamaño muy pequeño que se han extendido por el organismo.

Microbios con luz para detectar el cáncer
Un trabajo publicado en "Nature Biotechnology" indica que inyectar en el organismo bacterias y virus que emiten luz parece ser un método seguro para localizar tumores, tal como han comprobado en modelos animales investigadores de la Universidad Loma Linda (Estados Unidos).
