Echinococcosis : epidemiology and genotyping of echinococcus speices in Sudan

Abstract EN

Cystic echinococcosis (CE) is considered as a re-emerging disease in various regions, e.g.

the Middle East, central Asia, and northern and eastern Africa.

In sub-Saharan Africa, CE is highly endemic.

In this study, data were collected in abattoir-based surveys in Tamboul town (Central-Eastern Sudan,) and in Nyala abattoir (Darfour region).

Out of 1012 camels examined in Tampoul (713) and Nyala (299) an infection rate of 16.1% and 29.1 % was reported, respectively.

The favorite site for camel’s cysts is the lung (81 %).

Fertility rate of cysts encountered from camels is about 57 %.

This finding appears to reflect the importance of the camel as a major intermediate host of this zoonotic disease in Tamboul and Nyala area.

Echinococcus isolates (81) collected from camels were genotyped by PCR-RFLP and specific G5/6/7 PCR.

In all cases, the G6 genotype of E.

canadensis was found.

The public-health impact of these finding are discussed in terms of the various species and genotypes of Echinococcus and the role of each in human health.
