Studies Of Various Strains Of Echinococcus Granulosus In Livestock In Libya: Prevlence, Ultra-Structure, And Genotypes Of Hydatid Cysts.

Hydatidosis of livestock is a widespread parasitic infection; Libya is not an exception. A total number of 32,971 livestock from different regions in Libya was examined for the prevalence rate. Morphological and molecular characterizations of E. granulosus isolates were also examined. the total prev...
