118 SANITARY ENTOMOLOGYLeptomonas m'U8cae-domesticae . (Burnett) is a parasite of M'U8cadomestica Linnaeus, M. nebwo Fabricius, Fann,ia scalaris Fabriciu!,!,Pollenia nulis Robineau-Desvoidy, Teichomyza f'U8ca Macquart, Luciliasp., Pycnosoma putoriwm Wiedemann, Scatophaga lutaria Fabricius,Neuroctena anilis Fallen, Horno,lomyia coroina Verrall, and Sarcophagamurus, undergoing complete metamorphosis in the bodies of the flies.Patton (1910) has demonstrated that the disease may be transmittedfrom fly to fly as folloW's: the food becomes infected from the feces ofthe infected flies which have fed on it; uninfected flies may become infectedby ingesting either t~e long flagellates, the short encysting forms,or the cysts, in the feces of other flies, or in food contaminated by otherflies.Leptomonas pycnosomae Roubaud is a ,parasite of Pycnosomaputoriwm. 0Leptomonas roubaudi Chatton is a parasite in the Malpighian glandsof Drosophila confusa Staeger.Leptomonas sarcophagae (Prowazek) is a parasite in the gut ofSarcophaga haemorrhoidalis Fuller and another species of Sarcophaga.Leptomonas soudanensis Roubaud is a parasite of Pycnosomaputoriwm.Leptomonas stratiomyiae (Fantham and Porter) is a parasite ofStratiomyia chameleon Linnaeus and S. potamida Meigen. Fantham andPorter (1916) proved it experimentally pathogenic by inoculation toMus m'U8culus.Leishmania tropica (Wright), the cause of ORIENTAL SORE ofman, may be taken up in the crithidial stage by M'U8ca domestica andthe organism demonstrated 48 hours after feeding, according to Carter(1909). According to Wenyon (1911) who investigated BAGDADSORE, M'U8ca domestic a may readily feed on the sores and take upLeishmania, but there is no development of the organism and no parasiteswere found in the feces. On the other hand, Row, working with CAMBA YSORE believed the organism transmissible by M'U8ca domestica up tothree hours after the fly had fed on infected sores. He found the gut contentsof flies infective for a monkey three hours after the fly had taken upLeishmania, but Patton (1912) maintains that Cambay sore never commencesin a cut, scratch or abrasion, and failed to transmit the diseasein this manner in numerous experiments with M'U8ca nebulo and Musca sp.A new investigation, however, is warranted by Row's statement, seekingfecal infection of wounds.Rhynchoidomonas luciliae Patton is parasitic in the Malpighiantubules of Musca nebulo and Lucilia serenissima.
