Study of the Fertility and Morphostructural of Echinococcus Granulosus in Algeria



An examination of fertility of 1200 hydatid cysts found in postmortem examination of 350 bovine carcasses (450 cysts), 1230 sheep (630kystes), 787 (120kystes) goats slaughtered at abattoirs in the province of Djelfa, these cysts were localized in the liver and lung most of species slaughtered were female sex oriented adult age at slaughter for various reasons, the work began in January 2009 until January 2011, samples were taken after post-mortem examination of the bodies has tropism for hydatidosis, organ samples were preserved in formalin or alcohol 92 °, and kept cool, and the hydatid fluid was aspirated with a syringe and kept in petri dishes. Our results showed that the total fertility rate was (44.44%, % 50.80, 22.50 %) rates of infertility (27.10 %, 3.80 %, 77.50 %) and calcified cysts was (28.40 %, 11.10 %, 00 %) respectively for bovine, ovine, caprine, we considered that any cyst containing protoscoleces (hydatid sand) was fertile and those acéphalocystes (without protoscoleces) are sterile. However, we studied the morphology and consistency of cysts found, it was observed that the form was the most unilocular Unikystique rependue, whereas the form unilocular polycystic was observed in younger subjects, and those with advanced age had cysts or calcified or with the casein, our results are consistent with several authors in the literature.
