Concerning Certain Parasitic Protozoa Observed in Africa

Two new species of trypanosomes,Trypanosoma channai n. sp. fromChanna punctata andTrypanosoma qadrii n. sp. fromClarias batrachus

“…Further, the length of the free flagellum in the tkree different forms and the number of folds in the undulating membrane vary from those of the present form. The trinaorphic form described by Dutton et al (1907) has 4 lobed granular kinetoplast unlike in the present form. T. occidentalis Becket 3'74 C C Narasimharnurti and B Saratchandra (1967) which is also trimorpkic has myonemes in the stumpy forms which are absent in the present form.…”

Trypanosoma chattoni Mathis & Leger, 1911 in Rana pipiens of southern Ontario: morphometrics and a description of the division process

“…This condition was observed in 13/100 specimens in this study. According to our observations, the round frog trypanosome illustrated in earlier work (Ivanic, 1935;Dutton et al, 1907;Fantham et al, 1942) is clearly T. chattoni. Consequently, this organism is cosmopolitan in distribution, occuring in frogs and toads from southeast Asia, Africa, Europe and North America.…”

“…These authors identified them as T. rotatorium (Mayer, 1843) Laveran & Mesnil, 1901 and assumed the round forms were derived from the broad forms by contraction (e.g. Dutton et al, 1907;Fantham et al, 1942). More recently, Baker (1977) observed organisms that resembled T. chattoni in stained blood smears from two species of African anura (Ptychadena mascareniensis Dumeril & Bibron, 1841;Phrynobatrachus natalensis Smith, 1849).…”

“…Round trypanosomes have been observed in frogs and toads from Africa (Dutton et al, 1907), Europe (Ivanic, 1935) and North America (Fantham et al, 1942). These authors identified them as T. rotatorium (Mayer, 1843) Laveran & Mesnil, 1901 and assumed the round forms were derived from the broad forms by contraction (e.g.…”

“…A primeira descrição de um tripanossoma de crocodilo foi feita na África e corresponde a espécie atualmente identificada como T. grayi (Dutton et al, 1907), também encontrada em moscas tsé-tsé; sua transmissão aos crocodilos ocorre por contaminação oral, com fezes da tsé-tsé ou por ingestão de moscas esmagadas (Hoare, 1931). A inclusão de T. grayi no grupo dos tripanossomas de crocodilos favorece a hipótese da origem do clado neste vetor (Viola et al, 2009a).…”
