Akmn. Islam et Ptk. Woo, EFFECTS OF TEMPERATURE ON THE INVIVO AND INVITRO MULTIPLICATION OF TRYPANOSOMA-DANILEWSKYI LAVERAN ET MESNIL, Folia parasitologica, 39(1), 1992, pp. 1-12
Temperature directly affected the in vivo and in vitro multiplication
of Trypanosoma danilewskyi Laveran et Mesnil. The parasitemia in exper
imentally infected goldfish (Carassius auratus L.) increased rapidly a
t 20-degrees-C and reached its peak in 3 to 5 weeks post-infection. Th
e multiplication was slower at 10-degrees-C. The parasitemia declined
after the peak at 20-degrees-C. Lowering of temperature of the infecte
d goldfish from 20-degrees-C to 10-degrees-C slowed multiplication of
the parasite. Similarly, raising of temperature of infected fish from
10-degrees-C to 20-degrees-C resulted in rapid multiplication of the p
arasite. These were confirmed in the in vitro studies. It is suggested
that lower temperature slows the multiplication of the parasites beca
use T. danilewskyi is a parasite of a warm water host (Carassius aurat
us gibelio Bloch).
