Earlier this year White Nose was discovered for the first time in the Pacific North-west. This is disheartening news.
The question begs: what can we do more to prevent this spread? Obviously we can stop visiting caves. But are there steps we can take before we reach that conclusion? What do you think?
From the article:
On 11 March 2016, a moribund little brown bat (Myotis lucifugus) was found in King County, WA (United States), and submitted to a local wildlife rehabilitation center. The animal presented with dried and contracted areas of crusted skin on the wings and died 2 days later. Swab samples of the wings were positive for P. destructans by real-time PCR (8), and the bat was confirmed to have WNS in accordance with defined histopathologic criteria (9). An isolate of P. destructanswas obtained by culturing a portion of wing skin on Sabouraud dextrose agar containing chloramphenicol and gentamicin at 13°C.
In eastern North America, P. destructans appears to be spreading clonally, with all isolates exhibiting no genetic diversity at the markers examined (10). However, isolates of the fungus from Europe display significant genetic variation (11). To determine whether the isolate of P. destructans from Washington matched the clonal lineage from eastern North America, we conducted whole-genome sequencing using the Ion Torrent Personal Genome Machine (PGM) on the Washington isolate (NWHC#27099-001), as well as on three additional isolates of P. destructans from eastern North America. These isolates originated from M. lucifugus bats collected in Albany County, NY, in 2008 (NWHC#20631-008) and in Iowa County, WI, in 2016 (NWHC#26994-002) and a tri-colored bat (Perimyotis subflavus) in Jackson County, AL, in 2015 (NWHC#44797-145).
