Tuberculosis
Científicos alemanes publican en el "Journal of Experimental Medicine" que presentar elevados niveles de hierro en el organismo parece incrementar el riesgo de que las personas infectadas por Mycobacterium tuberculosis desarrollen la enfermedad pulmonar. Señalan que ya existía sospecha de la relación entre las concentraciones de hierro y la capacidad de reproducción del bacilo, ya que en África se había observado que las personas que ingieren mayores cantidades presentan mayor riesgo.
Los investigadores del Max Planck Institute for Infection Biology demuestran ahora que la tasa de reproducción de la bacteria aumenta en ambientes ricos en hierro, tanto en cultivos como en ratones.
Consideran que el hallazgo puede dar lugar a nuevas estrategias para combatir la tuberculosis.
