Journal ArticleDOI

Bat White-Nose Syndrome: An Emerging Fungal Pathogen?

TL;DR: Direct microscopy and culture analyses demonstrated that the skin of WNS-affected bats is colonized by a psychro-philic fungus that is phylogenetically related to Geomyces spp.
Journal ArticleDOI

Communication among Oral Bacteria

TL;DR: Considering that the majority of oral bacteria are organized in dense three-dimensional biofilms on teeth, confocal microscopy and fluorescently labeled probes provide valuable approaches for investigating the architecture of these organized communities in situ.
Journal ArticleDOI

Experimental infection of bats with Geomyces destructans causes white-nose syndrome

TL;DR: It is demonstrated that exposure of healthy little brown bats to pure cultures of G. destructans causes white-nose syndrome and that the recent emergence of WNS in North America may represent translocation of the fungus to a region with a naive population of animals.
Journal ArticleDOI

Inoculation of bats with European Geomyces destructans supports the novel pathogen hypothesis for the origin of white-nose syndrome

TL;DR: It is demonstrated that altered torpor-arousal cycles underlie mortality from white-nose syndrome and provide direct evidence that Gd is a novel pathogen to North America from Europe.
Journal ArticleDOI

Autoinducer 2: a concentration-dependent signal for mutualistic bacterial biofilm growth

TL;DR: It is shown that mutualistic and abundant biofilm growth in flowing saliva of two human oral commensal bacteria, Actinomyces naeslundii T14V and Streptococcus oralis 34, is dependent upon production of AI‐2 by S.’oralis 34 and its concentration is critical for mutualism between two species of oral bacteria grown under conditions that are representative of the human oral cavity.
