The Department of Biology Discusses a Master’s Thesis on a Biological and Molecular Study of the Efficacy of Some Plant Extracts Against Head Lice Infestation in Humans

Discussion of a Master’s Thesis

The Department of biology at the College of Education for Pure Sciences discussed the master’s thesis for student (Zainab Qassem Muhammad Helou) entitled (Biological and molecular study of the efficacy of some plant extracts against the infestation of the parasite Pediculus humanus capitis), under the supervision of Assistant Professor Dr. (Yarob Mudar Al-Qazwini). The study aimed to:
1- Knowing the extent of the spread of the parasite and the associated risks.
2- Comparison of several plant extracts and volatile oils applicable in combating head lice.
3- Molecular diagnosis of local isolates and their comparison with internationally recorded isolates.
As for the most prominent conclusions:
Through the results obtained in this study, we conclude the following:
1. . The prevalence of head lice infestation in some districts of Babil Governorate, and the highest prevalence was in the district of Al-Hashmiya.
2. The highest prevalence of head lice appeared in December and January.
3. The most affected age group was within 6-8 years and females are more susceptible to infection than males.
4. The extracts of volatile oils and alcoholic and aqueous extracts of lavender and sage plants had an effect in combating head lice.
The recommendations were as follows:
1. Head lice infestation can be reduced through health and social education and periodic inspection of primary school pupils by health committees.
2. The possibility of using a mixture of plant extracts synergistically possessing special volatile oils.
3. Conducting studies for accurate diagnosis of the active substance of the two plants, lavender, and sage.
4. Field experiments applied to the injured.
5. Experiment with plant extracts with volatile oils at all stages of the parasite’s life cycle.
6. Conduct molecular experiments on a larger scale.
After extensive scientific discussion and listening to the student’s defense of her thesis, her research method, and her use of sources and references, the thesis was approved with honors. Congratulations to the student, her supervisor, the College of Education for Pure Sciences, and the University of Karbala, the glue for this scientific achievement and more creativity in the service of our beloved Iraq, and God Almighty’s success and payment.
