Identity of Trypanozoon stocks isolated from man and a domestic dog in Liberia.

Abstract

The isoenzyme patterns (electrophoresis on thin-layer starch gel) and the human serum resistance (blood incubation infectivity test) of a Trypanozoon stock from a dog and 14 stocks from man in Liberia were examined. The complete conformity of criteria for man-infectivity of the dog stock with 5 human stocks and the very close similarity to the 9 remaining stocks from the same epidemiological locality indicates the dog as a reservoir host of gambiense sleeping sickness.
