Lipid Biosynthesis and Maturation Signals in Batrachochytrium Dendrobatidis In Vitro
Batrachochytrium dendrobatidis (Bd) is a fungal parasite 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 …

The drivers of variation in susceptibility to the amphibian-killing fungus, batrachochytrium dendrobatidis
The fungal pathogen Batrachochytrium dendrobatidis (Bd) is regarded as a primary driver of the dramatic global declines experienced by amphibian populations in recent decades. The threat posed by Bd extends into pristine regions, decimating populations naïve to the pathogen. The patterns of genetic …

Prevalence of Batrachochytrium Dendrobatidis in an Amphibian Communities of Central Texas and Tamaulipas, Mexico
Batrachochytrium 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 …

Prevalence assessment of the amphibian chytrid fungus Batrachochytrium dendrobatidis across two habitat types in East Tennessee
… investigating the pathogenic amphibian fungus Batrachochytrium dendrobatidis (Bd) are a foremost priority for biologists. Understanding effects of habitat variation on Bd prevalence is important for identifying populations that are most at risk and can help to inform management decisions. Using …

Differences in Gene Expression Responses to Heat Shock Between Warm- and Cool-Adapted Isolates of Batrachochytrium dendrobatidis
Batrachochytrium dendrobatidis (Bd) is one of the most destructive emerging infectious diseases to impact wildlife populations in modern history. Bd displays drastically different patterns of infection, both between distinct amphibian species and between different climates; this has resulted in …

Comparative genomics of bacteria from amphibian skin associated with inhibition of an amphibian fungal pathogen Batrachochytrium dendrobatidis
… in amphibians that is primarily caused by Batrachochytrium dendrobatidis (Bd). We analyzed whole genome sequences of 40 bacterial isolates that had been previously cultured from the skin of four amphibian species from Virginia, USA, and tested for their ability to inhibit Bd growth via an …

Evaluating efficacy of anti-Batrachochytrium dendrobatidis probiotic treatment on Pacific Chorus Frogs (Pseudacris regilla) at current and modeled climate change temperatures
… threats, including the chytrid fungal pathogen, Batrachochytrium dendrobatidis (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 …

The Barrier Properties of the Skin of Aquatic and Semi-Aquatic Vertebrates
… the effects of a deadly amphibian fungus, Batrachochytrium dendrobatidis, on skin TJ proteins of a frog are documented for the first time. This thesis provides novel information on skin TJ proteins of aquatic and semi-aquatic vertebrates and how they respond to environmental change.

Amphibian Community Composition And Disease Susceptibility In Ridge-Top Wetlands Of The Daniel Boone National Forest
… species, and (3) if prevalence of either Batrachochytrium dendrobatidis (Bd) or ranavirus differs between natural and constructed wetlands of the London Ranger District, where construction methods, wetland density, and wetland placement differ from those in previous studies conducted in …

Genetic structure and disease prevalence of boreal toads (Bufo boreas) in Glacier National Park
… elevation. I tested a subset of the samples for Batrachochytrium dendrobatidis (Bd), the fungal pathogen which causes chytridiomycosis. Thirty-seven of 109 toads tested positive for Bd. Infection prevalence was not correlated with elevation, but—surprisingly—increased with individual …

Natural History and Conservation of Bolitoglossine Salamanders in Central Panama
… within the study site. A chytrid fungus, Batrachochytrium dendrobatidis, was detected on B. biseriata and O. parvipes but I did not observe any mortality resulting from infection. Oedipina at the site were detected mainly on wet nights. Oedipina complex and B. biseriata detections …

Some like it cold: interactions between the northern frog biting mosquito, Culex territans (Walker 1856), and its amphibian hosts
… giant anuran trypanosomes, and the fungus Batrachochytrium dendrobatidis at Mountain Lake Biological Station and explore the potential role of Cx. territans in transmitting these pathogens. Overall, this work provides insights into the biology of Cx. territans and the implications it may …

Tetrodotoxin, fungal pathogen infection, and bacterial microbiome associations are variable in the skin microecosystems of two Taricha Newt 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 including host-associated skin microbes aiding defense through resource …

The effects of salinity on the cutaneous microbiome and pathogen infection on the Pacific Tree frog (Pseudacris regilla) in Monterey Bay, California, USA
… may reduce susceptibility to pathogens such as Batrachochytrium dendrobatidis (Bd). The Moro Cojo Slough State Marine Reserve (MCSSMR) (California, USA) is known as an abundant breeding ground for endangered/threatened amphibian species. To test and expand the salt refuge hypothesis, I evaluated …

Effects of Anthropogenic Environmental Stressors on Amphibian Immune Defenses and Host-Pathogen Interactions Across Temperate and Tropical Systems
… alteration, but also because of fungal pathogen Batrachochytrium dendrobatidis (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 …

Impact of Chytrid fungus pathogen on the skin microbiome of frogs in northern Idaho and Turnbull National Wildlife Refuge, Washington
… 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 documented loss of biodiversity attributed to a disease. …
