Abstract Camel trypanosomosis is a life-threatening disease in the camel species and responsible for severe economic losses either in milk or meat productions. This study was carried out on the south-east area of Algeria on camels of various ages and either sex from two herds. Microscopic examination of blood smears revealed higher levels of trypanosomosis caused by Trypanosoma evansi, an elongated parasite with a kinetoplast and a single nucleus located in its half-length and one flagellum with great heterogeneity.

This first investigation reveals higher infection rate than those observed in other countries using blood smears, the trypanosomosis attack has reached an alarming level and the occurrence of trypanosomosis at this high level on blood smears is like "the tree that hides the forest" and make up a serious and potential danger both on animal and public health.

Therefore, radical preventive and offensive drastic measures must be taken against this menacing disease at the critical points to prevent the economic losses and to avoid possible human transmission. Key Words: Blood smears, Camel, Parasite, Trypanosomiasis Introduction Camel trypanosomosis is caused by Trypanosoma evansi, a hemoflagellate parasite identified for the first time in India in In these regions, a huge number of camels Camelus dromedarius are concentrated on the dry desert south areas of the country and constitute the major source of animal protein for nomads.

Screening and detection of these hemoparasites helps initiate early diagnosis and instauration of appropriate actions and guarantee higher performance. Materials and Methods Animals and blood smears.

This study was carried out on two herds od Camelus dromedarius from the south-east region of Algeria. The samples were taken from dromedaries, 51 males and 49 females of different ages. Blood samples have been carefully taken after animal immobilization.

These samples were easily drawn from the jugular vein and especially when moderate pressure was applied on the way of the vein to mid-distance between the thoracic inlet and the head. Disposable sterile apyrogenic syringes C. Cretes, Alger, Algeria have been used after disinfection of the site of blood sampling.

The blood smears were achieved directly after blood collection without anticoagulants which may interfere and induce some cytoplasmic and morphometric cell changes and on the extreme provoke degranulation of some blood cells. Microscopic examination and measurements. Results After careful examination of the blood smears and identification of the formed blood elements, trypanosomes were observed on 14 blood smears 9 males and 5 females in different stages.

The parasites were very well visible with a spindle shaped stretched out body with one nucleus situated in its half-length and one flagellum Fig. About
