Chytridiomycota is a phylum of the Fungi kingdom.The name comes from chytridium (from the Greek chytridion, meaning "little pot"): the structure containing unreleased spores.. This explains why many fungicides are not effective against diseases caused by members of the Oomycota. [23] The disease then progresses as these new zoospores reinfect the host. [11], The geographic range of chytridiomycosis is difficult to ascertain. Wild amphibians should not be moved between habitats. Infectious drivers of these declines include the recently emerged fungal pathogens Batrachochytrium dendrobatidis and Batrachochytrium salamandrivorans (Chytridiomycota). Asexual reproduction is via sporangiospores, which can be released from the sporangium and carried by air currents. [15] The fungus dies at temperatures at and above 30 °C, which without the cloud cover from increased evaporation is more easily reached by the environment and can, therefore, more easily keep the fungus population in check. Chytridiomycosis, an amphibian disease caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), is an ideal system for studying the influence of temperature on host-pathogen relationships because both host and pathogen are ectothermic. Chytridiomycosis is an infectious disease in amphibians, caused by the chytrid fungi Batrachochytrium dendrobatidis and Batrachochytrium salamandrivorans, a non-hyphal zoosporic fungus. [19] The zoospores use flagella for locomotion through water systems until they reach a new host and enter cutaneously. [21] The fungus zoospores can survive within a temperature range of 4–25 °C and a pH range of 6–7. The zoospores can live for weeks in water depending on the temperature. Chytridiomycosis is easily spread by human activity. by phytophthora infestans and damping of seeding diseases cause by pythium. Excessive shedding of skin is seen in most frog species affected by B. Laboratory tests detect the DNA of Bd from skin samples or a skin swab of infected animals. Why some areas are affected by the fungus while others are not is not fully understood. The skin disease caused by these fungi is named chytridiomycosis and affects the vital function of amphibian skin. [16] Chytridiomycosis—an Emerging Panzootic Fungal Disease of Amphibians Chytridiomycosis is a fungal disease first [24], Besides amphibians Chytridiomycosis also infects crayfish (Procambarus alleni, P. clarkii, Orconectes virilis, and O. immunis) but not mosquitofish (Gambusia holbrooki). Epidermal changes caused by a chytridiomycete fungus (Chytridiomycota; Chytridiales) were found in sick and dead adult anurans collected from montane rain forests in Queensland (Australia) and Panama during mass mortality events associated with significant population declines. [16] An Archey's frog was successfully cured of chytridiomycosis by applying chloramphenicol topically. Recently, Chowdhary et al. 11-34A); and Physoderma, which causes the crown wart of alfalfa [P. (formerly Urophlyctis) alfalfae] (Fig. A few species in the order Chytridiales cause plant disease, and one species, Batrachochytrium dendrobatidis, has been shown to cause disease in frogs and amphibians. The class Chytridiomycetes contains three plant pathogenic genera: Olpidium, which infects the roots of many kinds of plants; Synchytrium, which causes black wart of potato (Fig. [17] The second stage takes place when the initial asexual zoosporangia produce motile zoospores.
