Is Batrachochytrium dendrobatidis a fungus?
Is Batrachochytrium dendrobatidis a fungus?
Batrachochytrium dendrobatidis, a pathogenic chytrid fungus implicated in worldwide amphibian declines, is considered an amphibian specialist.
What disease is caused by Batrachochytrium dendrobatidis?
Chytridiomycosis is an infectious disease that affects amphibians worldwide. It is caused by the chytrid fungus (Batrachochytrium dendrobatidis), a fungus capable of causing sporadic deaths in some amphibian populations and 100 per cent mortality in others.
What is considered the origin of the amphibian fungi Batrachochytrium dendrobatidis?
dendrobatidis originated in Africa or Asia and subsequently spread to other parts of the world by trade in African clawed frogs (Xenopus laevis). There is more recent information that the species originated on the Korean peninsula and was spread by the trade in frogs.
Does Batrachochytrium dendrobatidis affect salamanders?
Chytridiomycosis, an amphibian disease caused by the chytrid fungi Batrachochytrium dendrobatidis and B. salamandrivorans, is responsible for declines of amphibian populations worldwide (1). The recently discovered B. salamandrivorans (2) is severely impacting salamanders and newts in Europe (3,4).
Is Batrachochytrium dendrobatidis invasive?
1998. Chytridiomycosis Causes Amphibian Mortality Associated With Population Declines in the Rain Forests of Australia and Central America. Recommended citation: Global Invasive Species Database (2021) Species profile: Batrachochytrium dendrobatidis.
What does Batrachochytrium dendrobatidis do?
It is caused by the chytrid fungus (Batrachochytrium dendrobatidis), a fungus capable of causing sporadic deaths in some amphibian populations and 100 per cent mortality in others. The disease has been implicated in the mass die-offs and species extinctions of frogs since the 1990s.
Can Batrachochytrium dendrobatidis affect humans?
The chytrid fungus Batrachochytrium dendrobatidis is thought to have wiped out hundreds of species of amphibians and has been fingered as the cause of frog die-offs worldwide. Infections of Cryptococcus neoformans are rare among healthy people, but the fungus ravages those with compromised immune systems.
Can humans spread chytrid fungus?
It is important to recognise that humans may contribute to the transmission or spread of the chytrid fungus within and among amphibian populations.
Can chytrid fungus affect humans?
Chytrid fungus infects only amphibians because of their thin, sensitive skin. Humans, other mammals, reptiles, birds, fish, and invertebrates are not affected.
How does Batrachochytrium dendrobatidis spread?
Chytrid fungus is probably transferred by direct contact between frogs and tadpoles, or through exposure to infected water. The disease may not kill frogs immediately, and they can swim or hop to other areas before they die, spreading fungal spores to new ponds and streams.
Is chytrid fungus invasive?
Lionfish hunting native fish off the East Coast, kudzu vines blanketing large areas of the South, cane toads poisoning Australian animals—these are some common examples of destructive invasive species. But the globe’s deadliest invasive is invisible to the naked eye—the chytrid fungus.
What is the most invasive fungus?
chytrid fungus
Batrachochytrium dendrobatidis, a type of chytrid fungus, has caused declines in 500 amphibian species and driven dozens of them to extinction, according to the report, published Thursday in Science. This is the first time scientists have taken global stock of the problem.
