8 species of the world's most dangerous invasive microorganisms

Aphanomyces Astaci

1. Shrimp disease fungus: Aphanomyces astaci

Aphanomyces astaci is a fungus that lives in fresh water and parasites in shrimp. This disease has severely reduced shrimp stocks and has the risk of extinction of some of the 5 native species of European shrimp.

2. Banana flower rot: Banana bunchy top virus

Banana flower rot virus is a pathogen that causes flower top disease in bananas. Pentalonia nigronervosa is considered to be the most serious cause of economic loss among banana diseases worldwide.

Batrachochytrium Dendroba

3. Frog frog spore: Chytridiomycosis (Batrachochytrium dendrobatidis)

The frog spore was first discovered in 1998 by a group of international scientists from Australia, the United States and the United Kingdom and since then this mushroom has been regarded as the cause of serious decline in the number of Amphibian species in pristine areas of Panama and Australia.

4. Chestnut rot: Cryphonectria parasitica

The chestnut rot disease caused by fungi causes rotten branches and chestnut stems. After infection through wounds on the bark, the fungus penetrates deep into the trunk, causing the tree to die in the upper part of the infection. This fungus has destroyed most of the American chestnut trees.

5. Bird malaria: Plasmodium relictum

Parasitic spores are transmitted by mosquitoes and cause malaria in birds (bird malaria) can kill susceptible species (penguins) and birds (in the island of Hawaii), which are not yet present. Parasite species of this malaria.

Ophiostoma Ulmi

6. Wilt disease of Du tree: Ophiostoma ulmi

Wilt disease of Du tree and can cause death of plants due to fungus Ophiostoma ulmi. This fungus is transmitted by beetles to eat bark and through scion wood. This fungus causes serious disease in Du trees in South America and Europe.

7. Epidemic virus Rinde: Rinderpest virus

Rinde virus epidemic in even ungulates. The disease causes ulceration of the mucous membranes of the digestive tract and causes the animal to die very quickly. The disease also circulates in many parts of Africa, the Middle East and South Asia.

Phytophthora Cinnamomi

8. Phytophthora root rot: Phytophthora cinnamomi

P. cinnamomi is a type of root fungus that causes vascular disease and causes death to many plants. The disease thrives in moist environment and parasites on roots and proximal stem tissue. The disease weakens or kills trees because it hinders the transport of water and nutrients in plants.
