An in vitro and in vivo study was conducted to show the effect of dipeptide methyl ester on the protoscolices of Echinococcus granulosus and in naturally infected sheep. Easily punctured cysts were located by ultrasonography. A PAIR and PAI method were performed
bythe injection of dipeptide methyl ester into these cysts at a final concentration of 110 mmol/L. Follow-up was conducted
monthly by ultrasonography. After injection of the compound, the sheep were sacrificed at different times from 6 to 17 weeks.
The size and the morphological aspect of treated cysts were noted. Samples were collected for histologyand electron microscopy.
In conclusion, these studies revealed significant and rapid detachment of the membrane of the treated cyst and alteration
of the inner membrane in less than 5 min after injection of the drug, confirming the effect of the compound on the laminated
layer of the parasite. 相似文献

Sheep from the areas of Fondouk-Jeddid, Bir Mchergua and El Fahs, located in the Northeast of Tunisia, were examined by ultrasonography between 2001 and 2004 in order to assess their infection with Echinococcus granulosus, the agent of hydatid disease, and to evaluate this method as an efficient aire for hydatid cysts. A total of 1039 sheep, aged between 1 and 14 years was examined. The highest prevalence was found in sheep aged more than 8 years. The least infected animals were aged between 1 and 2 years. All hydatid cysts detected by ultrasound were located in the liver. In all age-groups, the dead cysts were more numerous than viable cysts. Eighteen positive sheep were autopsied and a comparison between ultrasound and autopsy results was performed. The results showed a prevalence of about 40% for the three areas. Ultrasonography allowed the cysts, deep or superficial to localize in the central or left part in relation to the caudal vena cava of the animals. Consequently, all the cysts were not detected with this technique. This work shows that ultrasonography confirms the importance of ovine hydatid cyst in Tunisia and that its use as a mass screening approach for cystic echinococcosis in sheep could be helpful for the monitoring of this disease in a hydatid control program without great stress for the animals. 相似文献
