IDENTIFICATION OF DICTYOCAULUS SPP. LARVAE IN A SHEEP COPROLITE FROM THE ARCHEOLOGICAL SALT MINE OF CHEHRABAD,NORTHWESTERN IRAN

خلاصه انگلیسی

Paleoparasitology, the study of human and animal parasitesin biological remains, is obtained from archaeological sites.The aim of this study was to diagnose the intestinal parasites of the sheep taking advantage of the coprolite obtained fromthe Chehrabad archaeological site, Zanjan, Iran. The preservation condition of the organic remains in this archaeological site is comparable with other situations elsewhere. Material & Method:Rehydration of the sample was performed using TSP solution. Several drops of formalin were added to the solution in present work in order to avoid fungal growth. After 10 days, the entire sample was carefully examined. To start paleoparasitology analysis, dating of the obtained materials has been already carried out in archeology section. Result:Out of the 153 prepared slides, larvae of Dictyocaulus spp.were observed in 2 slides.In this study the appropriatepreservation conditions of salt on this nematode larvae wereclearly seen. Identification of this parasite in only one feces of sheep (0.3gr) could be attributed to a possible high prevalence rate of sheep pneumonia due to Dictyocaulus spp in Sassanid era (500 CE). This report is the oldest evidence of the presence of this parasite in Iran.
