  • عزل وتعريف الفيروسات التي تصيب العائلة الباذنجانية وفحصها بالمجهر الالكتروني.
  • عزل وتعريف بعض الفيروسات التي تصيب بعض فاجات الجلي فش.

The recent FDA approval of Listeria-specific bacteriophage preparations for food preservation has opened the door to new applications of these natural bacterial killers. Bacteriophages are viruses that only infect and lyse bacterial cells and are harmless to mammalians. There is now a renewed interest to use the ability of these viruses to kill pathogenic bacteria for biotechnological purposes.

  • التدريب علي استخدام المجهر الالكتروني النافذ (TEM)  والماسح (SEM) .
  • جاري نشر بحث عن المستقبلات (CD81)  لفيروس التهاب الكبدي (C) .

HCV uses at least three receptors to enter and infect a hepatocyte. One of these receptors is the CD81 protein, which has the particular characteristic of  associating with numerous other proteins. It was by studying these CD81 partner proteins that the researchers identified the EWI-2wint protein, which prevents the recognition of CD81 by the hepatitis C virus and inhibits it at a very early stage in its infective cycle. This protein is present in other types of cells, which could explain why they are not infected by HCV. Discovery of the role of EWI-2wint in hepatocytes has demonstrated the complexity of the mechanisms of entry of HCV into its target cells, and opens the way to new therapeutic approaches.

2) The usage of Antibacterial Lytic Phages as Natural

Additive in Food Processing

3) The Efficiency of Bacteriophages as Nanobiological Reagents for Testing the Resistance of Lactic Acid Bacteria in Camel Milk

4) Extracting and identifying the virus species infecting aubergines and analysing them using electron Microscopy

5) Extracting and identifying some bacteriophage species infecting Jellyfish

6) The biological diversity of courgettes and their effect on the resistance to courgettes Mosaic Virus
