Report of an Oomycete Infection in a Western Lesser Siren (Siren intermedia nettingi) from Southeastern Oklahoma, USA

摘要

Infections from oomycetes (water molds) are among the top pathogens responsible for global amphibian declines (Blaustein et al. 1994; Blaustein and Kiesecker 2002; Densmore and Green 2007). In North America, several salamanders of all aquatic life stages have been reported to be infected with oomycetes, including the Spotted Salamander (Ambystoma maculatum), Marbled Salamander (Ambystoma opacum), Oklahoma Salamander (Eurycea tynerensis), Mudpuppy (Necturus maculosus), and Greater Siren (Siren lacertina) (Bishop 1926; Goin 1961; Petranka 1989; Connior et al. 2014; Urban et al. 2015). In a species account, Leja (2005) did not mention any reports of oomycetes in the Western Lesser Siren S. intermedia. Here, I document an oomycete infection in a S. i. nettingi from southeastern Oklahoma, USA.
