Microbiology is the study of microorganisms that are invisible to the naked eye. The most important goal of microbiologists is to control and eradicate infectious diseases. Today, we can claim with certainty that microbiology is at its peak with regards to its benefits to human as well as animal health. With the advent of chemical and biological drugs, the role and significance of medicinal plants for human health were at risk of being forgotten. But over time, there was considerable interest in medicinal plants. Given the increasing importance of the use of medicinal plants, the gradual replacement of chemical drugs, and the emergence of drug-resistant microbial strains and the ineffectiveness of chemical antibiotics to combat these strains, research on replacing these chemicals with plants has gotten greater attention and is at the center of this unit’s agenda. 

Medicinal plants are the best source for the extraction of different types of medicines. Herbal remedies have from many years ago formed the basis for the treatment of diseases. Although the production and use of chemical medicines has increases during the past century, many people nevertheless use traditional methods, such as herbal medicines for the treatment of diseases. 

Essential oils and herbal extracts have a wide range of pharmacological activities, such as anti-inflammatory properties, antispasmodic, expectorant, urinary, bile, and carminative and disinfectant properties. Apart from the above-mentioned cases, there is great interest in the field of medicinal plants in terms of the discovery of new herbal plants and the discovery of new forms of application of these plants and thus new research has been sparked in this field. 

The research goals of this group include:

  1. Evaluation of antimicrobial effect of essential oils and herbal extracts and ingredients against various microorganisms (bacteria, fungi, and yeast)
  2. Microbial evaluation of medicinal plants in the final formulation in infectious animal models
  3. Evaluation of the synergistic of antagonistic effects of essential oils and herbal extracts with antibiotics against drug-resistant strains
  4. Using essential oils and herbal extracts and ingredients of endemic plants in Iran to produce a new antibiotic for the treatment of infectious diseases
  5. Evaluation of antioxidant properties of essential oils and herbal extracts
  6. Gene cloning and expression
  7. Microbial control of cosmetics—health and medicinal products
  8. Challenge test to evaluate the efficacy of antimicrobial protective substance in medical products
    b. Microbial enumeration tests of bile-resistant Gram-negative bacteria
    c. Microbial enumeration test of Candida albicans yeast
    d. Microbial identification test of Clostridium sp
    e. Microbial identification test of Escherichia coli
    f. Total enumeration test of fungi and yeast
    g. Microbial identification test of Pseudomonas aeruginosa
    h. Microbial identification test of Salmonella
    i. Microbial identification test of Staphylococcus aureus
  9. Other duties related to the microbiology of medicinal plants
  10. Using the latest research findings and scientific advances in all stages of research to develop
