WILD ANIMALS AS RESERVOIRS OF MYIASIS-PRODUCING FLIES IN MAN AND DOMESTIC ANIMALS IN AFRICA F. ZUMPT South African Institute for Medical Research SUMMARY The following myiasis-producing flies in man and domestic animals have wild animals as reservoirs: Cordylobia anthropophaga (Blanchard)-Calliphoridae. Cordylobia rodhaini Gedoelst-Calliphoridae. Gasterophilus spp.-Gasterophilidae. Gedoelstia haessleri Gedoelst-Oestridae. Gedoelstia cristata Rodhain and Bequaert-Oestridae. Little is known about wild reservoirs of Chrysomya bezziana Villeneuve (Calliphoridae), which nowadays infests mainly cattle, which are to be regarded as the only important reservoirs. Wild hosts, however, must have played a decisive role in the past. Wild reservoirs of the Tumbu fly Cordylobia anthropophaga are mainly rodents; those of Lund's fly Cordylobia rodhaini are small antelopes and the giant rat. Both species are commonly . ) 0 found and are important pests of humans, dogs and several other domestic animals. 1 0 2 There are seven species of equine bot flies Gasterophilus spp. recorded from the Ethiopian d e region, two of them only from zebras. Most probably, however, all species are able to develop t a d in horses and donkeys as well as in zebras, so that the latter form true reservoirs for these ( r parasites. Occasional human skin infestations with first instar larvae (creeping myiasis) are e h s known. i l b Two Gedoelstia spp. are common parasites in the head cavities of wildebeest and harte u P beest, but under certain circumstances, the flies larviposit also on sheep, goats, cattle and horses e h t and cause "oculo-vascular myiasis" (uitpeuloog) which is accompanied by a high mortality. y b One case in man is so far recorded and was benign. d e t Oestrus ovis Linnaeus, the sheep nasal bot fly, has no wild reservoirs in Africa, according n a to recent investigations. r g e c n e c i l REFERENCE r e d n u ZUMPT, F. 1965.

Three Cases of Cutaneous Myiasis Caused by Cordylobia Rodhaini
Case Report Three cases of cutaneous myiasis caused by Cordylobia rodhaini Stefano Veraldi1, Stefano Maria Serini1, Luciano Süss2 1 Department of Pathophysiology and Transplantation, University of Milan, I.R.C.C.S. Foundation, Cà Granda Ospedale Maggiore Policlinico, Milan, Italy 2 Postgraduate Course in Tropical Medicine, University of Milan, Milan Italy Abstract Cordylobia sp. is a fly belonging to the Calliphoridae family. Three species of Cordylobia are known: C. anthropophaga, C. rodhaini and C. ruandae. The C. rodhaini Gedoelst 1909 lives in Sub-Saharan Africa, especially in rain forest areas. Usual hosts are rodents and antelopes. Humans are accidentally infested. Myiasis caused by C. rodhaini has been very rarely reported in the literature. We present three cases of C. rodhaini myiasis acquired in Ethiopia and Uganda.

Human Myiasis in Rural South Africa Is Under-Reported

Myiasis is the infestation of live tissue of humans and other vertebrates by larvae of flies. Worldwide, myiasis of humans is seldom reported, although the trend is gradually changing in some countries. Reports of human myiasis in Africa are few. Several cases of myiasis were recently seen at the Mthatha Hospital Complex, Mthatha, Eastern Cape Province, South Africa (SA). Objective. Because of a paucity of literature on myiasis from this region, surgeons and scientists from Walter Sisulu University, Mthatha, decided to document myiasis cases presenting either at Nelson Mandela Academic Hospital or Umtata General Hospital from May 2009 to April 2013. The objective was to determine the incidence, epidemiology, patient age group and gender, and fly species involved. The effect of season on incidence was also investigated. Results. Twenty-five cases (14 men and 11 women) were recorded in the 4-year study period. The fly species involved were Lucilia sericata, L. cuprina, Chrysomya megacephala, C. chloropyga and Sarcophaga (Liosarcophaga) nodosa, the latter being confirmed as an agent for human myiasis for the first time.

Case Report Furuncular Myiasis in Italian Traveler Returning from Kenya
Case Report Furuncular myiasis in Italian traveler returning from Kenya Ester Oliva1, Graziano Bargiggia1, Gianpaolo Quinzan2, Paola Lanza2, Claudio Farina1 1 UOC Microbiologia e Virologia, ASST “Papa Giovanni XXIII”, Bergamo, Italia 2 UOC Malattie Infettive, ASST “Papa Giovanni XXIII”, Bergamo, Italia Abstract Myiasis has been defined as the infestation of organs and/or tissues with dipterous larvae. They are especially widespread in tropical and subtropical areas. Cutaneous myiasis is its most frequent clinical presentation. This report presents a case of furuncular myiasis caused by the larva of Cordylobia anthropophaga in a 22-year-old girl living in Bergamo, Northern Italy, who returned from Kenya (Watamu) with a big, painful furuncle in her right gluteus. The patient accidentally removed the larva from a large pimple and took it to the infectious disease ambulatory clinic at the ASST “Papa Giovanni XXIII” Hospital, Bergamo. In the Microbiology and Virology Department of the same hospital, a larva of C. anthropophaga was identified and the diagnosis of myiasis was confirmed.
