Leger (M. ) & ViENNE (M. ). Epizootic 4 Trypanosomes chez les Bovid^s 

 de la Guyane francaise. [An Epizootic caused by Trypanosomes 

 in Cattle in French Guiana.] — Bull. Soc. Path. Exot., Paris, xii, 

 no. 5, 14th May 1919, pp. 258-266. 



Several diseases due to trypanosomes are known to occur in South 

 America. Mai de caderas, caused by Trypanosoma equimmi, a 

 disease in Venezuela due to T. veneztielense, a trypanosomiasis of mules 

 imported from the United States to Panama in 1910, caused by 

 T. hippiciim, and dourine, caused by T. equiperdum, all occur naturally 

 in horses, but no epizootic caused by these flagellates has hitherto 

 been known in cattle in South America. The present paper describes 

 a disease of this kind occurring in a village in French Guiana, which 

 is said to have broken out in July and August 1918, though, in view 

 of the slow nature of the disease, it is probable that it started unnoticed 

 at the end of 1917. It has been impossible to trace the source of 

 importation of the trypanosome into the village in question. The 

 symptoms of the disease are discussed and may be described as a 

 progressive anaemia, developing very slowly and almost always 

 terminating fatally. Certain symptoms frequently found in other 

 forms of trypanosomiasis are entirely absent, such as keratitis and 

 ophthalmia, precocious paralysis of the hind quarters, pulmonary 

 troubles, etc. The duration of the disease is not definitely known, 

 but the mortality is more than 52 per cent. , which is much higher than 

 that known in cattle infected with other forms of trypanosomiasis. 

 The number of trypanosomes in the blood of infected animals is 

 very variable, being sometimes very numerous in those that still 

 appear healthy, and sometimes very rare or absent during the course 

 of the disease. 



It is thought that this trypanosome is transmitted by some of the 

 numerous Tabanids that attack infected herds, although the authors 

 have searched in vain for flagellated forms in the intestines of some 

 of these flies. The trypanosome concerned is described. A few 

 experiments in inoculation were tried ; a guinea-pig and a dog were 

 both inoculated from an infected monkey, but neither animal con- 

 tracted the disease. 



The question is discussed as to whether this trypanosome is identical 

 with any of the flagellates naturally occurring in horses in South 

 America, and a comparison is made with those previously recorded 

 and with T. evansi, which has not yet been recorded from South 

 America. The conclusion is reached that the trypanosome which 

 infects cattle in the natural state, and cattle only, in French Guiana, 

 is a new species, the name proposed for which is T. guyanense.
