WDFW Research Scientist Dr. Marc Hayes recently brought visiting scientist Dr J. Michael Conlon to visit the Oregon spotted frog operation at Cedar Creek Corrections Center (CCCC). Dr. Conlon is a Professor of Biochemistry at Weill Cornell Medical College in Qatar, and is an internationally known biochemist whose research interests are focused on the purification and characterization of naturally occurring, biologically active peptides. He has worked on skin peptides for more than 40 years and with frog skin peptides for more than 10 years.

Dr. Conlon is interested in studying the skin peptides of the Oregon spotted frog (OSF) because they are very high in anti-bacteria and anti-fungal properties. The OSF also show a resistance to the amphibian chytrid fungus, known to be decimating amphibian populations worldwide.  The answer to why OSF are resistant to chytrid might be found in their skin peptides.

To better understand this, purified skin secretions need to tested for their activity against several strains of chytrid, requiring three steps: 1) obtain the skin secretions; 2) purify the individual peptides from those secretions; and 3) test each individual peptide from the skin secretions on several strains of the amphibian chytrid fungus.

SPP helped facilitate step 1, and steps 2 and 3 will be done in the UAE and at Vanderbilt University in Nashville, TN.   SPP and the frog interns at CCCC were pleased to be involved with this research as it will contribute significantly to the scientific knowledge of why OSFs are resistant to chytrid.
