Canine Trypanosomosis in the University of Nigeria Veterinary Teaching Hospital (UNVTH), Enugu State, Nigeria, Sub-Saharan Africa

Abstract

Trypanosomosis is an insect-borne protozoan disease and a serious constraint to livestock production. The incidence of this disease in dogs at the University of Nigeria Veterinary Teaching Hospital (UNNVTH) has not been reported. This study is designed to determine the incidence of canine trypanomosis presented to the (UNNVTH) between June to August, 1998. The incidence of trypanosome species infecting dogs was also determined. Standard trypanosome detection methods comprising of wet blood films, thin films and microhaematocrit centrifugation technique were used; while the degree of anemia was determined through the use of FAMACHA eye color chart and packed cell volume (PCV) values. Results indicate that of the 55 dogs, fifteen (15) were confirmed infected. The highest incidence was recorded in July (54%) whilst those of June and August were 19% each. Of the species of trypanosomes isolated, all but one Trypanososma congelense were Trypanosoma brucei. All the infections were associated with anaemia. There is a significant difference (PKey words: Canine trypanosomosis, dogs, Nigeria, Nsukka, Trypanosoma brucei, Trypanosoma congelense.
