    Abstract:
    This short communication describes the phylogenetic analysis of 48 Dirofilaria worms isolated from human patients in Ukraine. 102 cases were both of subcutaneous (47; 46.1%) and ocular (54; 52.9%) locations. Worms from 44 patients (15 subcutaneous and 29 ocular) were subjected to DNA extraction and amplification of a specific fragment of the 12S rRNA subunit, and sequences were used for phylogenetic analysis. Results showed that 13.8% of the ocular cases analyzed at molecular level were caused by Dirofilaria immitis. Very few cases of ocular human dirofilariosis due to D. immitis have been described in the literature to date, majority of them attributed to Dirofilaria repens. Our results show that ocular dirofilariosis cannot be excluded in areas of low endemicity for D. repens were D. immitis is also present.
