The presence of a microfilaria in the bone marrow of our patient may indicate that they can cross the blood vessel wall;7 the peripheral blood samples were recolected in the morning. Our patient began AIDS specific treatment and his CD4 lymphocyte count improved, but at the same time, his eosinophil count also increased. He remained asymptomatic all the time. We believe that the Mansonella perstans parasitic infection had no influence on the evolution of the HIV infection. We found a microfilaria in the bone marrow by chance. Diagnosis of Mansonella perstans filariasis should be made from peripheral blood by Knott’s technique. This possibility should be investigated in immigrants from Africa or South America with asymptomatic eosinophilia.
