Drs. Derbyshire and Gray have backgrounds in prokaryotic and human molecular biology respectively, and now we combine our expertise and enthusiasm in deciphering the molecular biology of mycobacteria. We use the genetically amenable Mycobacterium smegmatis as a model organism for our studies into gene expression, cell-cell-communication, protein secretion and conjugative transfer of chromosomal DNA. We use a combination of standard molecular genetic and genomic approaches, such as RNA-seq, ribo-seq and whole genome sequencing, to provide molecular insight into mechanism and genome architecture.

Senior Laboratory Technician JR-0002036

Senior Laboratory Technician JR-0002036

Applications due 3/24/26

Health Research Inc. is seeking a Senior Laboratory Technician to work within the Wadsworth Center, New York State Department of Health. The Senior Laboratory Technician will assist in supporting staff studying mycobacterial gene expression, gene function, and signal transduction in experimental models. The incumbent in this position will set up experiments at the bench to grow and manipulate bacteria, using state-of-the-art genetic, molecular biology, and genomic approaches. The incumbent will use assays that include next-generation-sequencing transcriptomics, cell viability, reporter plasmids, fluorescence microscopy and protein-interaction work. Cell-cell communication between mycobacteria is a recent and novel discovery made by the laboratory, and the genes involved in the communication pathway are conserved in both pathogenic and environmental mycobacteria. The goal of this grant-funded research is to functionally characterize cell-cell communication and determine its role in the biology and pathogenesis of mycobacteria. Please visit https://www.wadsworth.org/research/laboratories/derbyshire-gray for more information.

This position will be part of a dynamic team serving the Wadsworth Center’s mission in the New York State Department of Health’s efforts to protect and promote the health of New York’s citizens. Come be a part of Science in the Pursuit of Health®!

Wadsworth Center Publishes Discovery of a Key Signaling Protein in Mycobacteria

A new study from the Wadsworth Center and collaborators identifies a protein that regulates cell-to-cell communication in mycobacteria. The paper, titled “WhiB6 Transduces Contact-Dependent Signaling in Mycobacterium smegmatis and Coordinately Induces Both ESX-1 and ESX-4,” has been accepted for publication in the top tier journal, Molecular Microbiology.

Nine Seed Grants - Quintessentially Wadsworth Center

From environmental projects characterizing and quantitating contaminants in our water, food and even inside us, to infectious disease projects addressing antimicrobial resistance, “one of the world’s most urgent public health problems”, and studying factors that contribute to emerging infections, these seed grant-supported projects span a wide range of fields.

A $2.5 Million National Institute of Allergy and Infectious Diseases Grant Helps Elucidate Mycobacterial Cell-Cell Communication and the Evolution of Mycobacterial Pathogens

Before COVID most of us probably never thought about how the organisms that cause disease inherit their genetic material and how that impacts their ability to be “successful” pathogens.  Drs. Todd Gray and Keith Derbyshire at the Wadsworth Center have been thinking about this for a long time. 

Dr. Keith Derbyshire Named AAAS Fellow

Dr. Derbyshire joins the ranks of distinguished scientists recognized by the American Association for the Advancement of Science (AAAS) since 1874 - from Thomas Edison and Linus Pauling, to four of the 2018 Nobel Prize laureates. AAAS recognized Dr. Derbyshire “for distinguished contributions to the fields of molecular biology and microbial genetics, particularly in DNA exchange by transposition and conjugation in mycobacteria.”

New Study First to Describe Mycobacterial Cell - Cell Communication

For bacteria, sharing genetic information can be critical to survival. It can also make them fitter, better pathogens, and more able to evade the immune system and resist antibiotics. One way bacteria share their genetic information is by a process called conjugation, in which DNA is transferred from a donor to a recipient strain. Incorporation of the donor genetic information into the recipient chromosome can confer novel functions to the resulting transconjugant cells.
