Are we paying too much attention to cardio-pulmonary nematodes and neglecting old-fashioned worms like <it>Trichuris vulpis</it>?

<p>Abstract</p> <p><it>Trichuris vulpis</it>, the dog whipworm, causes an intestinal parasitosis of relevance in current canine veterinary practice. Its occurrence is well-known in pets, kennelled dogs and stray animals, and its eggs contaminate the ground in urban areas all over the world. Moreover, <it>T. vulpis </it>has been occasionally incriminated, though not convincingly substantiated, as a cause of zoonosis. This nematode is erroneously considered an "old-fashioned" pathogen with a consequent lack of up- to- date knowledge on several aspects of the infection. These, in turn, are still controversial and need to be studied in greater depth. This article reviews current knowledge of <it>T. vulpis</it>, together with a discussion of critical points in epidemiology, zoonotic hazard, diagnosis and treatment of canine trichurosis.</p
