[Ancylostomiasis in the mines. Apropos of 2 cases].
The etiological importance of Ancylostomidae in miners' anaemia has been discovered in 1880 by Perroncito during the boring of the Saint-Gothard tunnel in a dreadful epidemic. Thereafter in France, the illness disappeared between 1930 and 1940 because of the preventive dispositions realized. Two present cases of contamination in the coal mines of Lorraine due to N. americanus drive us to remember the interest of systematic faecal examinations of the miners at the engagement and every five years.
