Detection of Infectious Fungal Diseases of Frogs Inhabiting in Korea

Abstract

In recent years, there has been a rapid decrease in amphibian populations worldwide, and infectious diseases have been associated with this decline. Diseased frogs inhabiting Korea were collected from fields, and the diseases were identified by morphological and molecular analyses. Two fungal diseases-saprolegniasis and chromomycosis-were detected in the frogs. Saprolegniasis caused by Saprolegnia spp. was found in Rana plancyi chosenica from Gangwon-do and Rana huanrenensis from Chungbuk. Chromomycosis, which is caused by infection with Cladosporium cladosporioides, was detected in Rana catesbeiana from Busan.

Amphibian skin fungal communities vary across host species and do not correlate with infection by a pathogenic fungus

“…Members of this genus have been associated with mycoses in amphibians, such as mycotic dermatitis and mycotic myositis (Taylor, 2001). For instance, the species Cladosporium cladosporoides has been associated with the disease chromomycosis, a type of mycotic dermatitis, on invasive R. catesbeiana in Korea (Kim et al, 2008). In addition, captive amphibians in zoos can also harbour fungi from the genus Cladosporium at high relative abundances (Kearns et al, 2017), and in some cases, these infections result in cases of chromomycosis (Taylor, 2001).…”

Fungal Community on Skin Tissue of Amphibians Collected in the Santarém Region, Pará, Brazil / Comunidade De Fungos Do Tecido Cutâneo De Anfíbios Coletados Na Região De Santarém, Pará, Brasil

“…The genus Cladosporium is presented in some studies as belonging to the amphibian microbiome (Nickerson et al, 2011;Mendoza et al, 2012;Kearns et al, 2017;Ogoanah et al, 2017;Medina et al, 2019) making it a relatively common genus occurring in these animals. However, this genus is a major cause of chromomycosis in amphibians, which can affect both free-living and captive animals (Densmore and Green, 2007;Kim, Eom, Park, and Ra, 2008).…”

Rehabilitación y mantenimiento en cautiverio de ranas altoandinas (Telmatobius spp) decomisadas en la ciudad de Lima, Perú

“…Muchas mueren en este lapso con infecciones septicémicas conocidas como la «enfermedad de la pierna roja», causada por Aeromonas u otras bacterias que son parte de su flora (Hird et al, 1981). Otra enfermedad común en estos casos es la saprolegniosis, que es producida por un hongo oportunista cuando los animales pierden integridad del tegumento por lesiones físicas (Kim et al, 2008).…”
