[Lyme disease in Cuba? Report of possible cases].

Two possible cases of Lyme disease, which has not been reported in Cuba, but whose existence has been suspected for some years, are reported. These cases that were bitten by ticks and presented signs and symptoms compatible with this disease, according to literature, were serologically confirmed by different laboratory techniques (indirect immunofluorescence, ELISA and Western Blotting). The results suggest the presence of this borreliosis in Cuba.
