“…Indeed, we have found J. lividum on R. muscosa (Woodhams et al, 2007b). We note that bacterial additions in agricultural contexts are effective in controlling disease and do not negatively affect nontarget species (Berg et al, 2007;Scherwinski et al, 2008), which is encouraging. Whether to adopt a bioaugmentation strategy to control chytridiomycosis in nature presents a challenging ecological dilemma.…”

Emerging infectious diseases threaten human and wildlife populations. Altered ecological interactions between mutualistic microbes and hosts can result in disease, but an understanding of interactions between host, microbes and disease-causing organisms may lead to management strategies to affect disease outcomes. Many amphibian species in relatively pristine habitats are experiencing dramatic population declines and extinctions due to the skin disease chytridiomycosis, which is caused by the chytrid fungus Batrachochytrium dendrobatidis. Using a randomized, replicated experiment, we show that adding an antifungal bacterial species, Janthinobacterium lividum, found on several species of amphibians to the skins of the frog Rana muscosa prevented morbidity and mortality caused by the pathogen. The bacterial species produces the anti-chytrid metabolite violacein, which was found in much higher concentrations on frog skins in the treatments where J. lividum was added. Our results show that cutaneous microbes are a part of amphibians' innate immune system, the microbial community structure on frog skins is a determinant of disease outcome and altering microbial interactions on frog skins can prevent a lethal disease outcome. A bioaugmentation strategy may be an effective management tool to control chytridiomycosis in amphibian survival assurance colonies and in nature.

“…Ziel der vorliegenden Studie war es deshalb, die Bakterienflora von Möhren mit Methoden, die DNA-Fingerprints liefern, zu erfassen, und zu prüfen, inwieweit solche Techniken zur Unterscheidung der Bakterienbesiedlung auf ökologisch und konventionell erzeugtem Erntegut führen können. Solche methodischen Erfahrungen sind insbesondere für Studien der antagonistischen Wirkung von Bakterien gegen Schadpilze wichtig (Grosch et al 2001;Chaurasia et al 2005;Berg et al 2007). Diese Fragen sind auch und gerade für den ökologischen Landbau von besonderem Interesse.…”
