The most important disease of camel is Trypanosomiasis, vector bornprotozoal disease caused by Trypanosoma evansi parasite with wide. 1Nigerian Institute for Trypanosomiasis Research (NITR), Kaduna, Kaduna State, Camel trypanosomosis (surra), caused by Trypanosoma evansi, is the most. It is concluded that camel trypanosomiasis in Sudan is apparently caused by a single parasite species T. evansi and there were no other.

Amongst nonvisible but very important effects of surra is immunosuppression, which will be presented in the next section.

Immunosuppression of animals by a heavy parasite burden or stressful conditions in conjunction with underdosing may therefore play an important role in the development of drug resistance under field conditions []. Inside an infected country, tryapnosomiasis circulation of the parasite is almost free, especially with healthy carriers such as bovines, and also with more susceptible animals such as camels and mules, carrying the parasite with mild or subclinical signs.

Initially, this was attributed to active immunosuppression during infection. In the trypanosomiaiss Trypanozoonmechanical transmission of T.

In India, the stained blood smears revealed 7. In the same way, it has been proved recently that a T. Finally, the susceptibility of goats seems to be occasionally high in some reports, but, under natural conditions, most of the reports mention mild clinical signs due to T.

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. Curassonquoted by Hoare [ 4 ], said that it is conceivable that surra was introduced beyond Africa by the ancient Egyptians since they used dromedaries in their military campaigns in Arabia, Mesopotamia, Persia, and Baluchistan. Trypanosoma evansi has been found in the antelope Saiga tataricathe sambar deer Cervus unicolorRusa trypanosmiasis C.

It was described for the first time on the Island of Marajo Amazon estuary inand was further observed in Paraguay in Pantanal, Braziland Mato Grosso, Brazilbefore spreading into Bolivia, Venezuela, Guyana, and Colombia; it is present in Central America up to Mexico [ 4 ]. Ocular lesions have also been recorded [ ]. Although a number of authors have attempted to genetically characterize T. A complete loss of the trupanosomiasis DNA might even be possible and lead to akinetoplastic or dyskinetoplastic T.


Furthermore, TSIF had the capacity of downregulating type 2—oriented immune responses, being a key molecular actor of the trypanosome-induced immunosuppression [ ]. So far, it is advisable to keep the names of T. Camel trypanosomosis is caused by Trypanosoma evansia hemoflagellate parasite identified for the first time in India in View at Google Scholar W.

The potential of T. However, it is pathogenic in other Camelidae, such as the Bactrian camel Camelus bactrianus. Very little is known about natural infection in cats, but T.

Similarly, the Japanese vole Microtus montebelli proved to be highly susceptible since all 16 animals experimentally infected died [ 99 ].

View at Google Scholar M. Pig infection is often chronic with not only intermittent fever, anaemia, loss of weight, abortion, and cutaneous rash, trypanosomiasia also late nervous evolution, with hind leg paralysis Figure 8.

Transmission by stomoxes, which is the other name for dog fly, is also possible providing the trypanosomiaasis is living in close contact with another infected animal. From one country to another, since the detection of the infection is sometimes impossible, infected animals may occasionally be allowed to enter uninfected areas, as was recently observed in the Canary Islands, and the Spanish and French mainlands [ 42 ].


One of the immunosuppression characteristics induced by T. This review paper will be fruitful for the researcher as trypanosomiasks as field veterinarian in the field of diagnostics.

While almost all mammalian species are receptive, their susceptibility not only is highly variable from one species to another but may also be variable from one geographical area to another.

Initially developing in camels in North Africa, T. Be that as it may, a hypothetical evolution tree trypanlsomiasis summarize these data as presented in Figure 2.

Trypanosomes modulate macrophages through parasite factors and host cytokines to control cell polarization into distinct activation states M1, M2which may further contribute to susceptibility or resistance to infection []. Screening and detection of these hemoparasites helps initiate early diagnosis and instauration of appropriate actions and guarantee higher performance. Interestingly, a skin test in rabbits infected tryapnosomiasis T.

Losing in consequence its ability to perform oxidative phosphorylation [ 49 ], T. Productivity and health of camels Camelus dromedarius in Somalia: The effect of transhumance on the epidemiology of animal trypanosojiasis.

It was also introduced into France, inin a single epizootic focus in camels imported from the Trypanosomiasie Islands [ 4041 ]. Although it is not possible to date the initial spread of T. By frequent passage in immunosuppressed mice given subcurative drug treatments, T.
