DISEASES TRANSMITTED BY BLOODSUCKING FLIES 219 



Mastigophora: Binucleata: Leptomonidae 



Crithidia melopliagia Flu is normally a parasite of the sheep tick 

 fly, Melophagus ovinus Linnaeus, and has been experimentally transmitted 

 to rats and mice. Flu (1908) describes in the fly an asexual and sexual 

 reproduction. The latter is characterized by a process of reduction, 

 followed by conjugation with the formation of an ookinete and the infec- 

 tion of the eggs of the insect, which may cause a second generation of flies 

 to carry the organism. 



Crithidia nycterihiae Chatton is found in the parasite fly, Cyclopodia 

 sykesi Westwood. 



Crithidia pangoniae Rodhain, Vandenbranden, Bequaert and Pons 

 occurs naturally in Tabanus hilaris Walker, T. striatus Fabricius, and a 

 Tabanus sp. 



Crithidia tenuis Rodhain, Pons, Vandenbranden and Bequaert is 

 native to Haematopota duttoni Newstead, and H. vandenhrandeni Rod- 

 hain, Pons, Vandenbranden and Bequaert in Belgian Congo. 



Leishmania brasiliensis Vianna, cause of BOUBA or oral leishmaniasis 

 of Brazil and Paraguay, is believed by Brumpt and Pedroso to be carried 

 by bloodsucking flies, either Tabanidae or Culicidae. 



Leishmania tropica (Wright), cause of BISKRA SORE in Algeria, 

 and BAGDAD SORE in Bagdad, is believed by Wenyon (1911) and 

 Sergent and Sergent (1914) to be transmitted by Phlebotomus minutics 

 africanus Newstead. 



Leishmania uta Escomel, cause of UTA, a dermal lesion peculiar to 

 the western face of the Andes in Peru, is believed by Townsend to be 

 carried by Forcipomyia utae Knab and F. townsendi Knab. 



Leptomonas minuta (Leger) occurs naturally in the intestine and 

 Malpighian tubules of Tabanus tergestinus Egg. 



Leptomonas phlebotomi (Mackie) occurs in nature in Phlebotomus 

 minutus Rondani in India. 



Leptomonas simuliae (Georgewitch) occurs in nature in Simulium 

 columbaczense Schonberg in Europe. 



Leptomonas subulata (Leger) attacks Haematopota italica Meigen 

 in Southern France. 



Mastigophora: Spirochaetacea: Spirochaetidae 



Spiroschaudmnia glossinae (Novy and Knapp) occurs in the stomach 

 of Glossina. 



Telosporidia: Haemogregarmida: Haemogregarinidae 



Haemogregarina francae Dc Mello, a parasite of the dove, Columba 

 livia, is suspected of being carried by Lynchia maura Bigot.
