Documenting Range Expansion of the Invasive Pentastome Parasite, Raillietiella orientalis, Using Southern Black Racer and Eastern Coachwhip Road Mortality
Abstract The spillover of an invasive lung parasite, Raillietiella orientalis, is an important conservation concern for snake species in the southeastern US, as native snake hosts exhibit severe infections that can be fatal. In this report, we used opportunistic captures of road-killed snakes to document the presence of R. orientalis in 4 central Florida counties where it had not previously been documented. These new localities expand the known range of R. orientalis on the eastern and western coasts of Florida as well as fill in gaps of its known range. In 2 of 4 cases, R. orientalis individuals moved into the snake's mouth and emerged after host death. This evidence indicates that the use of road-killed specimens of frequently infected snake species may be a useful method for detecting R. orientalis. Additional surveys for R. orientalis are needed throughout the southeastern US, as this parasite is a major conservation concern for many snake species, its use of synanthropic intermediate hosts make its geographic spread unpredictable, and it is rapidly infiltrating additional populations of snakes.
期刊介绍:
The Southeastern Naturalist covers all aspects of the natural history sciences of terrestrial, freshwater, and marine organisms and the environments of the southeastern portion of North America, roughly bounded from North Carolina south to Florida, west to Texas, north to Oklahoma, and east back to North Carolina. Manuscripts based on field studies outside of this region that provide information on species within this region may be considered at the Editor’s discretion.
