Amphibians have declined around the world in recent years, in parallel with the emergence of an epidermal disease called chytridiomycosis, caused by the chytrid fungus Batrachochytrium dendrobatidis (Bd). This disease has been associated with mass mortality in amphibians worldwide, including in Costa Rica, and Bd is considered an important contributor to the disappearance of this group of vertebrates. While many species are susceptible to the disease, others show tolerance and manage to survive…

Characterization of the First Carbapenem-Resistant Pseudocitrobacter faecalis Harboring blaOXA-181 in China
P. faecalis was clinically reported in China for the first time, and the blaOXA-181 gene it carried was located on a globally disseminated IncX3 plasmid, which indicated it was resistant to carbapenems, quinolones, and commonly used β-lactam/β- lactamase inhibitor combinations.


Characterization of Batrachochytrium dendrobatidis Inhibiting Bacteria from Amphibian Populations in Costa Rica
This is the first study characterizing anti-Bd bacterial isolates from amphibian populations in Costa Rica, including the characterization of two strains of Serratia marcescens presenting strong anti- Bd activity.
Batrachochytrium dendrobatidis infection in amphibians predates first known epizootic in Costa Rica
New data is provided on Bd infection rates of amphibians collected throughout Costa Rica, in the decades prior to the proposed epizootics, to suggest that Bd dynamics in Costa Rica are more complicated than previously thought.
Estimating Herd Immunity to Amphibian Chytridiomycosis in Madagascar Based on the Defensive Function of Amphibian Skin Bacteria
Several amphibian communities, including those in the amphibian diversity hotspots, Andasibe and Ranomafana, were estimated to be below the 80% herd immunity threshold, suggesting they may be at higher risk to chytridiomycosis if a lethal Bd genotype emerges in Madagascar.
Amphibian‐killing chytrid in Brazil comprises both locally endemic and globally expanding populations
Bd population genetics in this region support the hypothesis that the recently discovered Brazilian lineage is enzootic in the Atlantic Forest of Brazil and that Bd‐GPL is a more recently expanded invasive.
Substrate-Specific Gene Expression in Batrachochytrium dendrobatidis, the Chytrid Pathogen of Amphibians
A genome-wide study of Bd gene expression under two different nutrient conditions and discusses the roles of these different genes as putative pathogenicity factors and what they can teach us about Bd’s metabolic targets, host invasion, and pathogenesis.
Novel, panzootic and hybrid genotypes of amphibian chytridiomycosis associated with the bullfrog trade
The finding that Bd is capable of sexual reproduction between panzootic and endemic genotypes emphasizes the risk of international wildlife trade as a source of additional Bd epizootics owing to hybridization.
Shifts in disease dynamics in a tropical amphibian assemblage are not due to pathogen attenuation
The results suggest that host recoveries are not caused by pathogen attenuation and may be due to shifts in host responses, which provide insights into the mechanisms underlying disease transitions, which are increasingly important to understand in an era of emerging infectious diseases and unprecedented global pandemics.
Recent Asian origin of chytrid fungi causing global amphibian declines
Panzootic chytrid fungus out of Asia Species in the fungal genus Batrachochytrium are responsible for severe declines in the populations of amphibians globally. The sources of these pathogens have
