| concurrent infection with ranavirus, batrachochytrium dendrobatidis, and aeromonas in a captive anuran colony. | four species (dendrobates auratus, phyllobates terribilis, pyxicephalus adspersus, and rhacophorus dennysi) of captive anurans with a clinical history of lethargy and inappetence were found dead and were submitted for necropsy. gross lesions included irregular patches of sloughed skin and rare dermal ulcerations. histologic findings included epidermal proliferation that was most pronounced on the digits and that included intracytoplasmic chytrid organisms. bacteria were often associated with the ... | 2008 | 18817009 |
| single rat muscle na+ channel mutation confers batrachotoxin autoresistance found in poison-dart frog phyllobates terribilis. | poison-dart phyllobates terribilis frogs sequester lethal amounts of steroidal alkaloid batrachotoxin (btx) in their skin as a defense mechanism against predators. btx targets voltage-gated na+ channels and enables them to open persistently. how btx autoresistance arises in such frogs remains a mystery. the btx receptor has been delineated along the na+ channel inner cavity, which is formed jointly by four s6 transmembrane segments from domains d1 to d4. within the p. terribilis muscle na+ chann ... | 2017 | 28874544 |
| levels of batrachotoxin and lack of sensitivity to its action in poison-dart frogs (phyllobates). | batrachotoxin is present in remarkably high amounts in the skin of phyllobates terribilis. levels of batrachotoxin tend to be reduced when p. terribilis is maintained in captivity, but even after being confined for up to 6 years, these frogs were still at least five times more toxic than other phyllobates species used by natives for poisoning blowgun darts. batrachotoxin was not detectable in f1 progeny reared to maturity in captivity. nerve and muscle preparations from wild-caught frogs and fro ... | 1980 | 6246586 |
| a new strategy to infer circularity applied to four new complete frog mitogenomes. | we applied a novel strategy to infer sequence circularity and complete assembly of four mitochondrial genomes (mitogenomes) of the frog families bufonidae (melanophryniscus moreirae), dendrobatidae (hyloxalus subpunctatus and phyllobates terribilis), and scaphiopodidae (scaphiopus holbrookii). these are the first complete mitogenomes of these four genera and scaphiopodidae. we assembled mitogenomes from short genomic sequence reads using a baiting and iterative mapping strategy followed by a new ... | 2018 | 29721275 |
| new species of anthurium schott (araceae) from the kõkõi eujã natural traditional reserve of the pacific coast, cauca department, colombia. | the kõkõi eujã natural traditional reserve was created in 2019 to protect the golden poison frog (phyllobates terribilis myers, daly & malkin, 1978) in the cauca department of colombia. as part of the biodiversity inventory of the reserve a new species of anthurium with scandent habit was discovered. the new species is endemic to colombia and it is more similar to a. caldodsonii croat, a. boekei croat, and a. scandens (aubl.) engl., but differs by having widely lanceolate leaves with acuminate a ... | 2020 | 32913409 |
