Abstract

Cystic echinococcosis (CE) is a major medical and veterinary concern in the world. It is one of the significant diseases in livestock farming communities managed under extensive grazing system like Ethiopia. Domestic intermediate hosts are an important reservoir for the disease spread. A cross-sectional study was conducted to determine the occurrence and economic losses associated with CE in cattle slaughtered at Mekaneyesuse Municipality abattoir, South Gondor zone of Amhara Region, North West Ethiopia. Ante-mortem inspection, postmortem examinations of organs, hydatid cyst characterization and financial loss estimations were conducted. The study was conducted on 384 cattle. The involvement of different organs was as follows: lungs (46.09%), liver (45.22%), heart (6.09%), and kidneys (2.6%). Out of the total of 115 cysts observed, small cysts constituted 57.39%, medium-sized were 34.78%, and large cysts accounted for 7.83%. Of these 115 cysts, 53.9% were fertile which included both viable (29%) and non-viable (71%) cysts. Furthermore, 46.1% cysts were non fertile, 62.3% were sterile and 37.7% were calcified. Based on the origin of animal, the prevalence of hydatid cysts was recorded to be 31.25%, 24%, 22.05% and 14.25% in Tachgayent, Semada, Andabet and Estie district, respectively. Higher cyst occurrence was observed in animals with poor body condition (51.56%) followed by medium (13.7%) and good body condition scores (8.25%). The total annual economic loss due to the direct condemnation of organs and indirect losses were estimated to be 851,252.68 ETB ($16,061.06). This study revealed that CE is economically important disease at Mekaneyesuse, South Gondar Zone, Amhara Region, Northwest Ethiopia. A more comprehensive investigation is required on prevalence and genotyping of Echinococcus granulosus s.l. cysts is important also to identify and estimate the relative contribution of each species or genotype to the disease in this area. Moreover, efforts to enhance public awareness in the area should also be pursued.
