Abstract The hellbender (Cryptobranchus alleganiensis) is among the most intriguing and imperiled amphibians in North America. Since the 1970s and 80s, western populations of the Ozark and eastern subspecies in Missouri have declined by nearly 80%. As a result of population declines, the Ozark hellbender was recently federally protected as an endangered species, and the eastern subspecies was granted protection under CITES. Although habitat degradation is probably the biggest threat to… Expand
Piscicola geometra (Linnaeus, 1761) leech parasitizing two fish species hosts from Greater Zab near Aski-Kalak, Kurdistan-Iraq, morphological and molecular investigations
Samples of two fish species, Cyprinus carpio and Silurus triostegus were collected from Aski-Kalak and inspected for the presence of parasitic leeches from March 2018 to February 2019 with aExpand
Evidence of ectoparasite-induced endocrine disruption in an imperiled giant salamander, the eastern hellbender (Cryptobranchus alleganiensis)
Parasitic leeches may be capable of modifying endocrine physiology of the giant hellbender salamander, one of the most unique and imperiled amphibians in North America. Expand
Metazoan parasites of Odontophrynus americanus (Anura: Odontophrynidae) from the Serra da Bodoquena mountain range, Mato Grosso do Sul, Brazil
For many helminth parasite species, transmission may occur directly by active penetration of the parasite into the skin of the host, or through a complex life cycle, with one or more intermediate hosts required for transmission. Expand
Effects of Land Use on Hellbenders (Cryptobranchus alleganiensis) at Multiple Levels and Efficacy of Artificial Shelters as a Monitoring Tool
A multilevel approach was used to understanding whether hellbenders respond to land use by examining physiological indices, demographics and patterns of species occurrence as endpoints, indicating that land use can lead to changes in hellbender distribution given sufficient time. Expand
Haematological and immunological characteristics of eastern hellbenders (Cryptobranchus alleganiensis alleganiensis) infected and co-infected with endo- and ectoparasites
This work provides some of the first information about how hellbenders physiologically respond to end- and ecto- parasites, insights that could be critical to their conservation. Expand
Cortisol is the predominant glucocorticoid in the giant paedomorphic hellbender salamander (Cryptobranchus alleganiensis).
The results indicate that hellbenders produce cortisol as their predominant glucocorticoid, supporting a small and inconclusive body of literature indicating that some other amphibians may produce appreciable quantities of cortisol. Expand
What's New in the Scientific Literature? Infectious Diseases of Reptiles: Peer-Reviewed Publications, June 2015–January 2016
The genome sequences of two Salmonella enterica serotype Infantis strains isolated from a captive western lowland gorilla and a cohabitant black and white tegu in Brazil suggest that these strains are likely to pose a threat to human health. Expand
Current land use is a poor predictor of hellbender occurrence: why assumptions matter when predicting distributions of data‐deficient species
The potential for mismatch between areas likely to be identified as having high conservation priority based on the common assumption that hellbender occurrence corresponds to areas of high forest cover is investigated and those identified by well-informed models are investigated. Expand


Widespread trypanosome infections in a population of eastern hellbenders (Cryptobranchus alleganiensis alleganiensis) in Virginia, USA
An unknown species of trypanosome that was apparently widespread within this population of Eastern hellbender salamanders was discovered; 40 of the 71 individuals captured during 2011 were infected. Expand
Historic occurrence of the amphibian chytrid fungus Batrachochytrium dendrobatidis in hellbender Cryptobranchus alleganiensis populations from Missouri.
The study detected no evidence for endemism of Bd in Missouri hellbender populations prior to 1969, despite the fact that nearly one third of the hellbenders sampled were collected earlier. Expand
Phylogeny of the leech family Glossiphoniidae based on mitochondrial gene sequences and morphological data.
The phylogenetic relationships of the Glossiphoniidae (Rhynchobdellida) were investigated using morphological characters and the mitochondrial genes cytochrome c oxidase sub unit I and nicotinamide adenine dinucleotide dehydrogenase subunit 1 to provide insights into several problematic genus-level classifications. Expand
Life History and Distribution of the Leech Oligobdella biannulata (Moore, 1900) (Euhirudinea: Glossiphoniidae)
Oligobdella biannulata is a rare, endemic leech species originally described from a mountain stream near Blowing Rock, North Carolina, U.S.A, which reattaches to its host between late August and early October and attaches singly or in clusters on the limbs or axillary and inguinal regions of the salamander. Expand
Parasites have been implicated in mass mortality events and population declines of amphibians around the world. One pathogen associated with mortality events in North America is an IchthyophonusExpand
New Geographic Distribution Records and Host Specificity of Placobdella ali (Hirudinida: Glossiphoniidae)
Two species of exotic turtles, 3 red-eared sliders (Trachemys scripta elegans), and a single southern painted turtle (Chrysemys dorsalis), which is a state record for Connecticut, indicate the potential of introducing exotic turtles as a vehicle for the introduction of exotic leeches. Expand
Definition of a new genus of glossiphoniid leech and a redescription of the type species, Clepsine picta Verrill, 1872
A new genus, Desserobdella, is described to accommodate the leech Clepsine picta Verrill, 1872 which feeds exclusively on amphibians of northern and central North America and therefore deposits cocoons directly onto the substrate. Expand
Development of Babesiosoma stableri (Dactylosomatidae; Adeleida; Apicomplexa) in its leech vector (Batracobdella picta) and the relationship of the dactylosomatids to the piroplasms of higher vertebrates.
Observations on syngamy and sporogony of B. stableri in its leech host indicate that the family Dactylosomatidae should be placed in the suborder Adeleina (Eucoccidiida: Apicomplexa). Expand
Placobdella cryptobranchii (Rhynchobdellida: Glossiphoniidae) on Cryptobranchus alleganiensis bishopi (Ozark Hellbender) in Arkansas and Missouri
The dorsal pigmentation of live specimens of P. cryptobranchii is described for the first time and there were no significant differences in prevalence and mean intensity among various years and localities sampled. Expand
Redescription and molecular characterization of Placobdella cryptobranchii (Johnson & Klemm, 1977) (Glossiphoniidae, Hirudinida)
Leeches collected during August 2009 to August 2011 from five localities in Missouri facilitated a redescription and molecular characterization of Placobdella cryptobranchii, a rusty, reddish-brown dorsum with 2 lateral rows of unpigmented papillae and a 93–94% similarity to PlacOBdella ornata and 10–17% difference among other species of Placybdella.
