The Role of Symbiotic Bacteria in Disease Resistance and Conservation of the Critically Endangered Panamanian Golden Frog
… dendrobatidis (Bd), which causes the disease chytridiomycosis. The Panamanian golden frog (Atelopus zeteki) has not been seen in the wild since Bd spread through western Panama. In response to initial declines, golden frogs were collected from wild populations and placed in captive colonies …

Quantitative, Competitive PCR and Fluorescent Microscopy Methods for the Study of Batrachochytrium dendrobatidis
Chytridiomycosis is a disease affecting amphibian populations worldwide and is caused by the parasitic fungus Batrachochytrium dendrobatidis (Bd). The catastrophic decline in numbers of amphibians dictates the need for full characterization of the fungus and amphibian host responses. Significant …

Tetrodotoxin, fungal pathogen infection, and bacterial microbiome associations are variable in the skin microecosystems of two Taricha Newt species
<p>Chytridiomycosis is an amphibian disease linked to population declines and species extinctions, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd). While chytridiomycosis can result in host death, some amphibians are less susceptible to severe infections through intrinsic factors …

Evaluating efficacy of anti-Batrachochytrium dendrobatidis probiotic treatment on Pacific Chorus Frogs (Pseudacris regilla) at current and modeled climate change temperatures
… (Bd), the causative agent of the disease chytridiomycosis. Climate change and other stressors can have complicated interactions with amphibian disease. Some amphibian populations are less susceptible to chytridiomycosis due to factors such as symbiotic skin microbes that may inhibit Bd …

Lipid Biosynthesis and Maturation Signals in Batrachochytrium Dendrobatidis In Vitro
… of amphibians responsible for the disease chytridiomycosis and partly attributed to massive global population declines of frogs and salamanders. Many of the molecular mechanisms behind the growth and development of Bd and how the fungus invades and infects amphibian hosts are unknown. In …

Prevalence of Batrachochytrium Dendrobatidis in an Amphibian Communities of Central Texas and Tamaulipas, Mexico
… dendrobatidis (Bd), a fungus that causes chytridiomycosis on infected amphibians, and has been implicated as a potential causative agent in the amphibian population declines of the past 50 years. This study seeks to assess the prevalence of Bd in amphibian communities in Central Texas and …

Host-Pathogen Ecology: Effects of Species Ecology and Environmental Factors on the Intensity and Distribution of Disease Among Illinois Amphibians
… which is the fungal pathogen that causes chytridiomycosis in amphibians (Berger et al. 1998; Longcore et al. 1999). <italic>Bd</italic>'s effects are not completely known since some areas of the world have been studied (e.g., Panama, Lips et al. 2006; United States Sierra Nevada, Briggs et …

MICROBIAL COMMENSALS OF TRICOLORED BATS IN GEORGIA AND THEIR PROBIOTIC POTENTIAL
… emerged fungal pathogens of wildlife, such as chytridiomycosis in amphibians. Host microbiomes have come under investigation in other disease systems for their perceived connection with pathogen colonization and disease severity across taxa. This research focused on characterizing the …

Batrachochytrium dendrobatidis in Central California
… MAJOR PROFESSOR: Eric Schauber Amphibian chytridiomycosis has been identified as a disease responsible for the decline and extinction of many amphibian taxa world wide, but little research has been conducted on the disease in Mediterranean climates. To address this gap in the data I …

Effects of Anthropogenic Environmental Stressors on Amphibian Immune Defenses and Host-Pathogen Interactions Across Temperate and Tropical Systems
… (Bd). Bd infects amphibian skin, resulting in chytridiomycosis and a disturbance of the host skin bacteriome. I used multiple amphibian species from both neotropical and temperate systems to investigate my hypothesis that the primary amphibian glucocorticoid, corticosterone (CORT), would be …

Impact of Chytrid fungus pathogen on the skin microbiome of frogs in northern Idaho and Turnbull National Wildlife Refuge, Washington
… are under threat from the infectious disease chytridiomycosis, which is caused by the chytrid fungus Batrachochytrium dendrobatidis (Bd). Bd is associated with the population declines of an estimated 501 species, 90 of which are presumed or confirmed extinct, making this the greatest …

Assessing Diversity, Culturability and Context-dependent Function of the Amphibian Skin Microbiome
… of this, especially those associated with chytridiomycosis, a lethal skin disease caused by the fungus Batrachochytrium dendrobatidis (Bd). Amphibian skin can harbor diverse bacterial communities that, in some cases, can inhibit the growth of Bd. Thus, there is interest in using skin …

Using eDNA to construct community assemblages of amphibians at sites infected with Batrachochytrium salamandrivorans in the Netherlands.
… of the main culprits being the fungal disease chytridiomycosis. This fungus affects the skin of amphibians, leading to excessive skin shedding or skin lesions which, in many cases, result in death. The recently discovered Batrachochytrium salamandrivorans (Bsal) fungus, which only affects …

The Structure and Function of Amphibian Skin Bacterial Communities and Their Role in Susceptibility to a Fungal Pathogen
… factor in these declines is the skin disease chytridiomycosis, which is caused by the fungus Batrachochytrium dendrobatidis (Bd). Recent research suggests that the amphibian skin microbiota has anti-Bd activity and may be an important factor in host disease resistance. However, little is known …
