[2 cases of Lyme disease contracted in France].

Two new cases of Lyme disease are reported. Both were contracted in western France. In the first case, a tick bite was followed by a typical erythema chronicum migrans and then a subacute arthritis. High levels of specific antibodies were demonstrated. In the second case, only erythema chronicum migrans developed and serology remained negative. At least, 16 typical cases of Lyme disease have now been reported in France from several geographical areas.
