In a series of three experiments during March–October, 1998, two species of captive-bred poison dart frogs (Dendrobates tinctorius and D. auratus) were exposed to Batrachochytrium dendrobatidis, a recently-described chytridiomycete fungus (chytrid) that was originally isolated from a blue poison dart frog (D. azureus). All frogs exposed to the chytrids developed a fatal skin disease, whereas none of the control frogs developed skin lesions. The most consistent clinical sign in chytrid-exposed… 
Does Chytridiomycosis Disrupt Amphibian Skin Function?
TLDR
Evidence of inhibited rehydration in individuals exhibiting clinical signs of chytridiomycosis is provided, however, aclinical chy TRD does not severely affect amphibian skin function, and frogs that survive infection by Bd, even if they remain infected, may suffer no significant impairment in their physiological responses.
Co-localisation of Batrachochytrium dendrobatidis and keratin for enhanced diagnosis of chytridiomycosis in frogs.
TLDR
Staining protocol based on previously described methods to detect both B. dendrobatidis and keratin is developed, to improve the sensitivity and specificity of diagnosis of chytridiomycosis by inexperienced diagnosticians.
Batrachochytrium dendrobatidis zoospore secretions rapidly disturb intercellular junctions in frog skin.
Transmission of Batrachochytrium dendrobatidis within and between amphibian life stages.
TLDR
Experimental evidence is presented that R. muscosa tadpoles can be infected by fungal zoospores and that they can transmit infection to each other and to postmetamorphic animals.
Pathogenicity and Transmission of Chytridiomycosis in Tiger Salamanders (Ambystoma tigrinum)
TLDR
This is the first complete report of occurrence and pathology of chytridiomycosis in Salamanders in field-collected North American salamanders, and it is demonstrated that chyTridiomyCosis does not always lead to mortality.
DERMATITIS IN CAPTIVE WYOMING TOADS (BUFO BAXTERI) ASSOCIATED WITH FUSARIUM SPP.
TLDR
A specific underlying cause of disease could not be found, although the roles of humidity and Ranavirus infection are discussed, along with the well-known susceptibility of bufonids to fungal dermatitis.
Immmunological Clearance of Batrachochytrium dendrobatidis Infection at a Pathogen-optimal Temperature in the Hylid Frog Hypsiboas crepitans
TLDR
Repeated diagnostics using real-time polymerase chain reaction assays of postmetamorphic individuals at 28, 38, 45, 53, and 62 days after exposure demonstrated that Hypsiboas crepitans is able to clear infection within a few weeks at 23°C, demonstrating a temperature-independent and likely immunological mechanism for the clearance of Bd in a resistant amphibian species.
Does Chytridiomycosis Affect Tree Frog Attachment?
TLDR
It is proposed that tree frog attachment is a promising case to study the sublethal effects of a Bd infection on amphibians and the knowledge generated from such an approach could contribute to future research on Bd epidemiology and ultimately to the conservation of the biodiversity of arboreal anurans.
Susceptibility of the endangered frog Dendropsophus meridensis to the pathogenic fungus Batrachochytrium dendrobatidis.
TLDR
Repeated diagnostics using real-time polymerase chain reaction assays demonstrated that individuals that died accumulated a higher number of zoospores than those that survived, although this value was lower than the mean zoospore burdens observed in natural populations.

Cutaneous Chytridiomycosis in Poison Dart Frogs (Dendrobates spp.) and White's Tree Frogs (Litoria Caerulea)
TLDR
The results show clear patterns in squamous cell cancer of the head and neck carcinomas that have been identified in patients with locoregional control, and these patterns are consistent with those seen in animals treated with chemotherapy.

TLDR
Experimental data support the conclusion that cutaneous chytridiomycosis is a fatal disease of anurans, and it is hypothesize that it is the proximate cause of these recent amphibian declines.
Emerging infectious diseases and amphibian population declines.
TLDR
The role of these diseases in the global decline of amphibian populations is examined and hypotheses for the origins and impact of these panzootics are proposed.

IF k1(x) is any non-negative function in L1 (− ∞, + ∞), let us write: for n = 2, 3, … Then the function: is defined almost everywhere (although it is possibly infinite for some, or all, x).
