Experience
Dr. Ahmed Khalifa Mohamed Meshaal has extensive technical and research experience in microbiology and virology. He has worked on various projects related to microbiological analysis, including decontamination of human and ground units, bacterial identification through serological and biochemical methods, and the isolation of foodborne pathogens such as Escherichia coli O157:H7, Salmonella enterica, Staphylococcus aureus, and Shigella flexneri. His work has also involved studying the antibacterial properties of medicinal plants. He has contributed significantly to Hepatitis B research at the Medical Research Centre (MRC), Assiut University, where he worked on techniques like ELISA, PCR, and DNA extraction to study HBV in patient serum and peripheral blood mononuclear cells (PBMCs). Dr. Meshaal’s expertise extends to antiviral research, where he has investigated antiviral activity in vitro using tissue culture techniques. His technical skills and extensive research experience have made him an influential figure in his field.
Research Focus
Dr. Ahmed Khalifa Mohamed Meshaal’s research focuses primarily on microbiology, virology, and the application of microbiological techniques in public health. His work covers a wide range of topics, from foodborne pathogens to the detection of viral infections such as Hepatitis B. A key area of his research is studying the antimicrobial properties of medicinal plants, particularly spices and essential oils, against foodborne pathogens like Bacillus species and other harmful bacteria. His Ph.D. research on occult Hepatitis B Virus infection involved the use of advanced techniques such as real-time PCR, nested PCR, and the separation of PBMCs to analyze HBV DNA. Dr. Meshaal is also interested in exploring the antiviral activity of various compounds and their potential therapeutic applications. His interdisciplinary background in microbiology, chemistry, and biochemistry allows him to approach research from multiple angles, contributing to a broader understanding of infectious diseases and antimicrobial resistance.
