The College of Education for Pure Sciences discusses a doctoral thesis on a taxonomic study of some ectoparasite species from different hosts in Najaf Governorate.

The Department of Life Sciences at the College of Education for Pure Sciences at the University of Karbala discussed a doctoral thesis entitled “A Taxonomic Study of Some Ectoparasite Species from different hosts in Najaf Governorate” by student Fadhel Hussein Allawi.

The thesis was supervised by Assistant Professor Dr. Hanan Zuwayr as first supervisor, and Professor Dr. Sakina Jabbar Mushtat as second supervisor.

The study aimed to accurately characterize selected internal and external parasites from different hosts, combining morphological analysis using macroscopic observation, microscopy (LM), and microscopic examination (SEM) with molecular analysis (specific DNA markers). The study also aimed to determine the taxonomic status of the parasites, document their biological diversity, and clarify their evolutionary relationships. The study hypothesized that combining microscopic morphological and molecular assays would enhance diagnostic accuracy, contributing to a deeper understanding of biodiversity.

The study concluded that the nematode worm Ascaridia galli has been registered in the National Center for Biotechnology Information (NCBI) GenBank. The morphological characteristics of some parasites and arthropods were studied using an electron microscope for the first time.

The study recommended continuing morphological and molecular diagnosis, using scanning electron microscopy, of other parasitic species common in Iraq and those parasitic on vertebrate and invertebrate hosts to determine their genetic similarity and evolutionary tree worldwide. Transmission electron microscopy (TEM) was also used to study the internal components of parasitic worm species. The study also included conducting therapeutic experiments using drugs and plant extracts and studying their effects using scanning electron microscopy (SEM) to demonstrate the effects on the vitality of various parasite species.

The student received an excellent grade.
