Research of interest: Microbiology for Human and Aquatic Animal Health Thriving (MiHaaht)

imageThe overuse of broad-spectrum classical antibiotics may induce an antibiotic-resistant mechanism of bacteria and the accumulation of unused residues of drugs in the environment which, in turn, results in long-term negative effects on human and animal health. Therefore, the development of alternative antimicrobials for reduced pathogen infection & antibiotic resistance and improved food security & human and aquatic animal health is urgent.

We focus our research on microbial biodiversity and microbiome with the development of pharmabiotics, which are any biological materials isolated from gut microbiota, including probiotics, bacteriocins, and bioactive molecules, for application in food production and medicine sectors. Probiotics is “live micro-organisms which, when administered in adequate amounts, confer a health benefit on the host” (WHO) while bacteriocins are ribosomally synthesized antimicrobial peptides or proteins in almost all bacteria groups.

We have a passion to research in Applied and Medical Microbiology. Through research on microbiota of marine animals, we understand more about biodiversity and complex interaction among microorganisms with diverse biological activity to formulate novel probiotics or drugs in Aquaculture and Food Production sectors (Nguyen et al., 2014, Fish Shellfish Immunol), or on microbiome of humans, we have screened novel anticancer bacteriocins in Medicine (Nguyen & Nguyen, 2016, BioMed Res Int). Beside Microbiology and Molecular Biology approaches, we have found the power of computational tools to generate new biological understanding. Interestingly, microbiome is one of the richest untapped resources inside human and animal body which should be uncovered, especially on its link to host health.

We established and developed the collaboration with 30+ local, national and international partners, both higher education institutions (HEIs) and industries. We are also one of founder members of a Vietnam – UK network of HEIs, small and medium-sized enterprises (SMEs) and hospitals in Vietnam and UK (www.VUHEIE.org).

    I think that what you typed was very reasonable. But, what about this?
    suppose you wrote a catchier title? I am not suggesting your information is not solid., however suppose you added a title that grabbed people’s attention? I
    mean Research | Nguyễn Văn Duy’s Homepage is
    a little plain. You might look at Yahoo’s home page annd watch how they
    create article headlines to get people to click.
    You might add a related video or a related pic or two to grab people interested about
    everything’ve written. In my opinion, it could make your website a little bit
    more interesting.

  2. Good post. I learn one thing tougher on different blogs everyday. It can at all times be stimulating to read content from different writers and apply somewhat one thing from their store. I’d desire to make use of some with the content material on my blog whether you don’t mind. Natually I’ll provide you with a link in your web blog. Thanks for sharing.
