[Presence of free amebae of the Limax type in waters of the urban center of Rennes and of Liffre. II].

We confirm the results of our preliminary study in the Rennes district (France) (January to April 1974): free-living Limax amoebae are found in all the examined waters samples (56 per 62) except for the ones directly originated from underground waters and a difference upon the moment of the year appears as for the encountered species. We have not found Naegleria species. Some of these amoebae show a satisfactory growth at high temperature and on different nutritional media, but none are able to grows in liquid axenic media.
