Human Furuncular Myiasis Caused by the Flesh FlyWohlfahrtia opaca(Coq.) (Sarcophagidae: Diptera)

Cases of furuncular myiasis in humans have been reported in the literature from time to time, many of them having been attributed to parasitism by sarcophagid flies. O'Rourke (10) described a case of furuncular myiasis due toWohlfahrtia vigil(Walk.) in a month-old infant at Ottawa. He reviewed the life-history and distribution of the species and previous records of myiasis cawed by it. Israels and Shuman (4) published an informative general review of myiasis dermatosa. Hunt and Edwards (3) reported a case in a three-month-old infanr at Montreal. This is a report on similar cases that occurred at Lethbridge, Alberta, in 1953 and in 1955 and a review of other records for Western Canada and the United States.

INTESTINAL MYIASIS FROM RAT-TAILED MAGGOTS IN A WOMAN

THE OCCURRENCE of gastric myiasis in humans has occasionally been reported in medical literature; however, not without considerable discussion regarding the authenticity of the reports from various observers. What appears to be an authentic case of its occurrence in a woman was briefly presented by us at the annual meeting of the Colorado State Medical Society held in Denver on Sept. 18-21, 1951.1 REVIEW OF THE LITERATURE In 1909, McCampbell and Corper2cited a case of intestinal myiasis attributed to three species of dipterous larvae; among these was the rat-tailed maggot, Eristalis tenax. The patient was a farm woman living in Ohio. She had intermittent spells of abdominal distress over a period of years, accompanied by colicky pains, nausea, and vomiting. Cathartics were necessary to relieve constipation. After the administration of magnesium sulfate (Epsom salts) larvae were usually passed in liquid stools. The authors give a brief history

Wohlfahrtia (Diptera,Metopiidae) Myiasis of Mink in Alberta

In nearly every year our attention is drawn to one or more cases of human myiasis in various places in Alberta. Unfortunately, in every instance where these have concerned infants, the larvae had already been removed and placed in alcohol. We have submitted a number of these larvae co Dr. E. M. Walker, at Toronto University for determination. He has not cared to commit himself by identifying first instar larvae but he classified all specimens which were in the 2nd or 3rd instar as species ofWohlfahrtia. He, further, suggested that they might bemeigeniiCoq. At the time when he identified them for us, it was believed that this species, though described from Europe, did occur in Western Canada.

Human Intestinal Myiasis due to Syrphid Larvae

Summary The case herewith recorded represents the twenty-second instance of human myiasis by larvae of the family Syrphidae to be recorded in the literature In this instance the offending parasite was a member of the genus Eristalis, probably E. tenax. In addition to the form vomited before the patient was seen, seven larvae were expelled following anthelmintic therapy. Because of a complicating condition (bronchitis), it is not clear which, if any, of the child's symptoms can be attributed to the parasitic infestation. The cases of human myiasis by syrphid larvae recorded in the literature since 1918 have been collected.

MYIASIS IN THE FOOT OF A RAT BY WOHLFAHRTIA MEIGENII SCHINER. (DIPTERA, METOPIIDAE)

Cases of human myiasis have been recorded, on various occasions, from a number of widely scattered localities in Alberta. In several instances the causative larvae have been placed in alcohol and sent to this department for identification.
