Summary: The study investigated how the skin microbiome of wild Dhofar toads in Oman is influenced by host environment, pathogen presence, and host biology. The results showed that skin microbiome diversity is mainly influenced by host life stage, water source, and habitat disturbance. The network analysis revealed high site specificity in bacterial co-occurrence patterns.

Summary: This study investigated the dynamics of within-host coinfection and found that parasite density and identity have significant effects on these dynamics. The interactions between coinfecting parasites were found to be highly asymmetric, and exposure dose of one parasite was associated with host tolerance to another parasite's infection and the load of a third parasite.

Summary: The study suggests that toad tadpoles in anthropogenic habitats cope with environmental changes by increasing their stress response and negative feedback, showing higher endocrine flexibility. Water pollution levels may contribute to elevated stress response in tadpoles, while no infections by Batrachochytrium dendrobatidis or Ranavirus were found. Results from the common-garden experiment indicate that individual phenotypic plasticity plays a major role in habitat differences.

Summary: The skin microbial community structure of amphibians is linked to the clinical outcome of Batrachochytrium dendrobatidis (8d) infections. This study used multi-omics analyses in laboratory and field settings to demonstrate that 8d infection alters microbiome taxonomic and functional profiles.

Summary: Immunity changes through ontogeny and can mediate interactions between co-infecting parasites. Host immunity development alters the host responses to parasite exposures across different life stages. A study conducted on Cuban treefrogs exposed to fungus (Bd) and nematodes (A. hamatospicula) at different life stages found ontogenetic differences in immunity, but no evidence of increased immunosuppression in metamorphic frogs. There was also little evidence of facilitative interactions between the parasites, but Bd infection decreased immunity in metamorphic frogs, making them more susceptible to infection.

Summary: The study demonstrates that time lags between co-infections can affect parasite loads, in line with priority effects theory. Infections with Bd and Ranavirus either singly or in co-infections decreased host growth and survival.

Summary: Research shows that peracetic acid (PAA) can effectively kill the highly virulent Batrachochytrium dendrobatidis (Bd), helping to mitigate the spread of Chytridiomycosis disease and having no obvious adverse effects on tadpoles. However, the use of PAA can lead to a decrease in pH and dissolved oxygen in water, which needs to be addressed through aeration.

Summary: This study sequenced the whole genomes of bacterial isolates from amphibian skin in the Eastern US and tested their ability to inhibit the growth of the fungus Batrachochytrium dendrobatidis (Bd). The results revealed differences in gene families and biosynthetic gene clusters among the isolates, suggesting potential mechanisms for inhibiting Bd growth. Further research is needed to explore and verify these hypotheses.

Summary: Research has found that the persistence of two parasites in two different lakes, as well as two different amphibian species acting as hosts, varies due to ecological factors and host characteristics.

Summary: Understanding the threats to wildlife across space and time is essential. A study in Mesoamerica found that the destruction of habitats and the spread of the fungal pathogen Batrachochytrium dendrobatidis were the main drivers of decline in amphibian species.

Summary: The variation in host-associated microbial communities is correlated with disease occurrence and severity in different host species, suggesting the important role of the microbiome in pathogen defense. This study investigates the relationship between microbial communities and infection dynamics in amphibians, showing that the microbiome can mediate or be altered by pathogen exposure.

Summary: This research provides evidence that fog water may serve as a pathway for the transmission of the amphibian-killing fungus Bd. The study shows the passive transport of live Bd zoospores through artificial fog can infect susceptible hosts and lead to lethal chytridiomycosis. These findings are important for understanding the exposure mechanisms of direct-developing amphibians to aquatic pathogens and can aid in the development of control measures.

Summary: Emerging infectious diseases pose a threat to amphibian biodiversity worldwide, even in protected landscapes like the Greater Yellowstone Ecosystem. Research on ranaviruses and the amphibian chytrid fungus in this ecosystem has provided valuable insights into their impacts and potential conservation strategies. Climate change, increased visitor use, and associated impacts may exacerbate the effects of these diseases.

Summary: Dynamic interactions between host, pathogen, and host-associated microbiome were investigated in Eastern hellbender salamanders challenged with Batrachochytrium dendrobatidis (Bd). Vaccination did not affect pathogen load, but stimulated different host gene expression depending on the vaccination type. The microbiome was altered by Bd, but anti-Bd microbe abundance or richness did not correlate with pathogen burden. Our findings suggest that the immune response of hellbenders to Bd is initially vigorous but ineffective in controlling disease, and interactions with antifungal skin microbiota do not influence disease progression.

Summary: Understanding the causes of population variation in host response to disease, and the mechanisms of persistence, can serve as vital information for species conservation. One such mechanism of population persistence that has gained support is the demographic process of compensatory recruitment. However, high-elevation populations may be limited in their ability to exhibit compensatory recruitment relative to lower elevation populations.
