Subcutaneous Dirofilaria repens infestation in non-descript canines.

Dirofilaria repens is a filarial nematode which cause subcutaneous dirofilariosis. Dogs, foxes and cats are the definitive hosts and principal reservoirs of the parasite. We report cases of D. repens infestation in non-descript canines from Goa, India. The nematodes were enclosed within fibrous capsule or freely present in the tunica vaginalis of the testes, in sub-cutaneous tissue of foreleg and body cavity. The parasite showed well-developed thick multilayered cuticular ridges in the outermost layer, followed by transverse smooth muscles striations.
