Hepatocystis brayi n. sp. est décrit et séparé de la deuxième espèce parasite des Sciuridae de Malaisie, H. malayensis Field et Edeson, 1950.
Il s’agit d’une espèce très particulière, puisque toute son évolution tissulaire se fait à l’intérieur de la cellule hôte, dont le noyau et le cytoplasme sont très hypertrophiés. De plus, le peu d’abondance de la substance colloïde dans les mérocystes est un caractère exceptionnel dans le genre.
Enfin, H. brayi est un parasite d’hôtes fréquentant les étages moyen et inférieur de la canopée, H. malayensis les étages supérieur et moyen.
Abstract
Hepatocystis brayi n. sp. is described and separated from the second species parasitising Malaysian Sciuridae, H. malayensis Field and Edeson, 1950.
H. brayi is characterized by: 1) the evolution of its tissue schizonts which are intracellular throughout all their development; the cytoplasm and the nucleus of the host cell are highly hypertrophied; 2) the scarcity of the colloid.
The schizogony persists for several months in the liver of infected animals and the gametocytaemia apparently undergoes seasonal relapses.
H. brayi is a parasite of hosts occurring in the middle and under canopy, H. malayensis the middle and top canopy.
