Microbial Metagenomics Division

What we do

We collaborate and provide services in the filed of microbial ecology and evolution using metabarcoding and metagenomics tools. Our location near the Dead Sea is a front row sit to extreme habitats and their microbial communities. We take an ecological approach towards the study of holobionts, in which all the aspects of an ecosystem are applicable to the host and its symbionts.

Hire Our Services

Metagenomics is a high throughput approach to understand the biological function of a pool of organisms in a sample. We can analyse your sample and predict the biological community and its biological functions in high resolution. We can test the change in the function and taxonomy following treatment or change in conditions. Find out more here.

Our laboratory is proficient in DNA metabarcoding and metagenomics techniques. We are experienced with many sample types including soil, water, or tissue from a range of organisms, and can conduct complex bioinformatic analyses. We can assist all stages of research starting with the experimental design, through data production and analysis, and ending with publication grade figures and data archiving. More information in the services page.

R & D Projects

The Acacia tree is very unique, capable of existing where most trees do not. Dr. Ashraf Al Ashhab studies it's phylosphere bacteria to understand their contribution to the tree's high durability and to harness them for use in agriculture and cosmetics. This is done in collaboration with Dr. Gideon Winters from DSASC in Hatzeva.

The Dead Sea is a unique climatotherapy location. Michael Brandwein, Prof. Zvi Bentwitch and Dr. Amir Szitenberg study the skin microbiome associated with a range of diseases, and the effect of climatotherapy on skin bacteria. This research is in collaboration with Dr. Marco Harari of the DMZ medical center, Prof. Emmilia Hodak from the Department of Dermatology, Rabin Medical Center, and Prof. Zvulunov from The Department of Dermatology, Soroka Medical Center

Root knot nematodes are a major crop pest throughout vast regions of the glob. They are known to interact with soil and plant bacteria to successfully infest plants. Dr. Amir Szitenberg is interested in the microbial soil and plant community associated with intense infestation and in ways to manipulate it in order to inhibit nematode infestation.

Fish are an extremely susceptible cultivar, with elaborate water treatment procedures usually in place. Dr Ashraf Al-Ashhab is interested in the effect of the commonly used UV treatment on the native bacterial community of fish skin, and the role of the skin community in fighting of infections. This research is a collaboration with Galit Sharon DVM, from ILOR in Eilat.

The Dead Sea basin is a unique source of biodiversity, given a range of extreme habitats. We characterize the unique microorganismal biodiversity in water bodies in the region.

Root Knot nematodes are a devastating crop parasite around the world. The Arava protected horticulture is also affected by this pest. Yet, genomic resources and microbiome information in this group is scares. Dr. Amir Szitenberg studies the genome evolution of Root Knot nematodes and their associated bacteria in order to understand their biology.
