Great thread !

Here is some information for clarification ?

Chytrid zoosporangia is a fungus
Batrachochytrium dendrobatidis (is the causative agent of chytridiomycosis) of which the frog will succumb to.

great life cycle posters !

<"Chytridiomycosis
In terms of its effect on biodiversity, chytridiomycosis is quite possibly the worst disease in recorded history. First identified in 1998, this potentially lethal skin disease is caused by the chytrid fungus Batrachochytrium dendrobatidis, which has been detected on at least 287 species of amphibians from 36 countries. " >

<"Chytrid zoosporangia live in the heavily keratinized stratum corneum and stratum granulosum of the frogs’ pelvic patch, digits, and ventral body, and in the keratinized mouthparts of tadpoles. Associated epidermal changes included irregular cell loss, hyperkeratosis, and excessive sloughing of the skin. " >

<"Two leading hypotheses have been put forward to explain how Batrachochytrium dendrobatidis directly kills its host: 1) toxic, proteolytic enzymes are released by the fungus, and 2) loss of electrolytes negatively affects osmoregulation and/or oxygen uptake, two primary functions of amphibian skin." >

A must read if you keep frogs and/or breed frogs :

After I read this ( in 2009) --- I removed ALL soil substrate from my Agalychnis ( callidryas and moreletii) enclosures and have NOT put it back.
For what it's worth:
I use an ( UNPROVEN- my recipe): cleaning solution every Saturday on the walls and floors of my tree frog enclosures.
( including on the cricket bowls and soaking dishes). Except for the plants-- they are housed like a "lab" or quarantine enclosures; like the paper towel theory but 'pretty'. I use- reusable ( fleece fabric) substrate (changed 3 times a week) of which is put through the washing machine in hot water and bleach /rinsed twice and put in a hot dryer to evaporate any left over bleach remnants. The substrate is soaked in de-chlorinated water before put back in to the enclosure. This has been my routine since of 2009. I have lost one frog ( recently ) since 2009 due a to a puncture wound behind the eye - from a plant branch.
