Un grupo de investigadores de EE.UU. han revelado que en el metro de Nueva York hay más de 15.000 tipos de bacterias y microorganismos, casi mitad de los cuales son desconocidos para la ciencia.
Un grupo de científicos de la Universidad de Medicina Weill Cornell, EE.UU., ha realizado un análisis de las bacterias y microorganismos que hay en el metro de Nueva York, que acoge a diario 5,5 millones de viajeros. En total se han identificado 15.152 tipos de formas de vida, de las que casi la mitad no se corresponden con ninguno de organismos existentes, es decir son microorganismos no registrados por la ciencia.
De todos modos, los investigadores recalcan que la mayor parte de las formas de vida detectada son inofensivas para los humanos. “Los resultados no sugieren que los habitantes de Nueva York estén en peligro”, asegura la investigación, publicada en ‘The Wall Street Journal’.
