A multilocus genetic analysis based on protein electrophoresis was carried out on 39 adult specimens of Dirofilaria repens and 31 of D. immitis. Seventeen enzymatic loci provided reliable electrophoretic patterns which were compared in the two species. All loci except one were monomorphic. Fixed alternative allozymes were found at 13 loci while only 3 loci shared apparently the same allozyme in the two species. The polymorphic locus, Pgm, also showed alternative allozymes. This remarkably high genetic divergence, which presumably reflects a very old speciation process, allows an easy characterization of D. repens and D. immitis and supports their classification in the subgenera Nochtiella and Dirofilaria, respectively.
