Title: Biogenic Synthesis of Nanomaterials for Combating Pathogenic Microbes
The rise of multidrug-resistant (MDR) pathogens has become a global health threat and an economic burden in providing adequate and effective treatment for many infections. This large-scale concern has emerged mainly due to mishandling of antibiotics (ABs) and has resulted in the rapid expansion of antimicrobial resistance (AMR). Nowadays, there is an urgent need for more potent, non-toxic and effective antimicrobial agents against MDR strains. In this regard, clinicians, pharmacists, microbiologists and the entire scientific community are encouraged to find alternative solutions in treating infectious diseases cause by these strains. In its “10 global issues to track in 2021”, the World Health Organization (WHO) has made fighting drug resistance a priority. Infectious diseases continue to attack human beings as emerging and re-emerging infectious diseases, opportunistic infectious diseases and infection with drug resistant microorganisms. Discovering new antibiotics and chemically modifying existing antimicrobial drugs were the main strategies to address microbial resistance. However, no major classes of antibiotics were introduced between 1962 and 2000 and there were no successful discoveries of novel antimicrobial agents since 1987. To escape a scenario whereby the healthcare community is forced back to the pre-antibiotic era, there is a demanding for novel or alternative antibiotic therapy. This speech was conducted with the aim of examining the effect of green-synthesized antimicrobial nano-materials and/or nano-drug carriers against the MDR microbes as a potential alternative treatment option to the challenging infectious pathogen in the hospital settings.


Title: Unlocking the power of endophytic fungi as promising sources of bioactive
Plants are well known to live in close association with microbial populations. In particular, the symbiotic associations with microorganisms such as fungi and bacteria called endophytes. A fungal endophyte spends a part or whole lifecycle colonizing inside healthy tissues of its host plant, typically causing no apparent symptoms of the disease. These endophytes represent an untapped pool of valuable bioactive metabolites. Moreover, they are more active than their free counterparts; so, they are recognized as sources of novel bioactive compounds with potential applications in agriculture, medicine, and the food industry. As such, they are promising candidates in the field of nanotechnology.
