[Tholozan and plague in Persia].

In Persia since 1858, Tholozan studied between 1870 and 1882 the plague foci of the iranian Kurdistan which shall be dealt a century later (1947-1963) with Dr. M. Baltazard and his co-workers from the Pasteur Institute of Teheran. Tholozan had already pointed out the localization of the disease in some well defined villages and gave a good clinical description mentioning the traces of flea bites on the patients skin. One knows nowadays that wild rodents (Meriones) are the storing places of the plague bacilli in the Kurdistan. Tholozan's observations confirmed by modern ones allow to consider him a great loïmologist of modern times.
