The Helminth Parasites of Dogs in Marseilles

Dogs are notoriously susceptible to helminthic infections, especially of the alimentary tract. Their role as carriers of such important pathogenic organisms as Echinococcus and Taenia multiceps makes the study of their parasites of more than academic importance, so much so that by an order of the United States Bureau of Animal Industry, all sheep dogs imported into the U.S.A. have to be held in quarantine pending a faecal examination for helminthiasis (Wigdor, 1919). Statistical surveys of the helminth parasites carried by dogs have already been made in a number of different countries. In this country the subject has been studied by Lewis at Aberystwyth, in Wales; and by Nuttall and Strickland in Cambridge. Brown and Stammers have made a parasitological survey of the dogs in London based on post-mortems combined with examination of faeces from London pavements.
