Mycotic infections in frogs due to a Phialophoralike fungus. Sabouraudia 11: 99–105

A fungal epizootic among captive frogs in U.S.A. was investigated histologically and myeolo-gically. It was not possible to determine which of the fungi (Cladosporlum herbarum, Scolecobasi-dium humicola or Phialophora sp., probably gougerotii) was the pathogen. Utz (1963) in his description of human chromoblastomycosis, aid that infection in animals had not been reported. Yet, the first record of multiple deaths, due to a fungus, presumably very closely allied to those causing the human disease, dates from 1926 when Scott (1926) reported the death of 20 frogs and several salamanders from the collection of the Zoological Society of London. The disease started with epidermal ulceration, mainly on digits and in the ventral region. Mycelia and spores were seen in sections of the viscera with the exception of the heart, the brain and the nervous system, the fat bodies and the ovaries. Giant cells were seen in the spleen and in "other organs". The colour of the fungus was not mentioned. Since the manner of growth of this "Monilia ' does not correspond with any previously known species Scott (1926) described it as a new species, Monilia batrachea. A few frogs, treated with mercurochrome, survived the epizootic
