. Animal parasites and human disease. Medical parasitology; Insects as carriers of disease. SPARGANUM PROLIFERUM 253 and from 0.3 mm. to 2.5 mm. (^V to xV of an inch) in width, but in one Japanese case they were uniformly larger, reaching a length of three inches. Their peculiarly irregular shape is due to the unique method of proHferation by the growth of buds or super- numerary heads. These apparently become detached, leave the cyst, and become encapsuled themselves after migrating in the subcutaneous tissue. This explains the increasing num- bers of acne-like spots or nodules containing worms, which were re- ported by the patients. Attempts made by Ijima to pro- duce adult worms by feeding the larvse to various domestic animals failed, and nothing is known of the life history or mode of infection be- yond a suspicion that the eating of raw fish is responsible for it. Dr. Fig. 99. Sparganum proUferum, Gates, who discovered the Florida f™™ man in Florida. Much en- larged. (After Stiles.) case, reported that there was prob- ably a similar case in Florida a few years before, the patient having moved to" California where he died " eaten up with worms." The rare occurrence of this peculiar and serious parasitic disease is evidence that the mode of infection is unusual. The suspicion that it results from eating raw fish is sufficient reason for discrimination against this kind of food even in places where this or other human parasites which come from raw fish are not positively known to occur..
