Effect of Batrachochytrium Dendrobatidis on Anura Populations Batrachochytrium

Abstract

Chytrium (Batrachochytrium Dendrobatidis) is a chytrium fungus that causes amphibian chytriomycosis. They were first discovered in 1998 and have been responsible for a large number of amphibian deaths over the next decade. Chytrid fungus grows on amphibian skin and produces free aquatic spores. They are widely distributed in deserts and lowland forests to cold hilltops. They can cause disease in upland (low temperature) amphibians, causing significant mortality. Chytrid infection has been associated with large numbers of amphibian deaths in north, south and central America, Europe and Australia. In this paper, the author summarized several factors influencing the transmission of chytrid by analyzing the existing data and data, including the transmission route, the worldwide distribution range and harm degree of chytrid, and the existing research and discussion on the elimination and prevention methods of chytrid. After collecting and analyzing data and literature, the author comes to the following conclusions: Firstly, the fungus originated in Africa and spread around the world through trade in animals such as xenopus africanus, and was endemic in Africa for many years before spreading around the world. Secondly, chytridiomycosis is one of the important factors contributing to the extinction of some amphibians in many places, including Africa and Australia. Thirdly, the factors that will affect the chytrid strain of chytrid fungus, the active degree and spread range of factors are temperature, human activities, amphibian’s own immunity, chemicals in pesticides, etc.
