Clinical and laboratory features of human dirofilariasis in Russia

Our data are consistent with the opinion of KI Skriabin about that human as «dual facultative host» for dirofiliaria. It is rare that parasite in human body is able to develop to the imago stage (according to our observations - 11.4%). The immune response to invasion by dirofiliaria in human is manifested as dense connective tissue which forms a capsule. According to our study the rare cases (22) of detection the sexual mature D. repens (10.4%) were localized inside the capsule. Observations of patients with D. repens infection allowed concluding that human for this helminth is «a biological deadend».
