Abstract:
... Ranaviruses are emerging as serious pathogens across ectothermic taxa, recently causing mass die-offs including entire chelonian populations. Amphibians may serve as reservoirs for chelonian infections. To assess this idea and determine whether chelonians in the Midwest are infected with (or at risk for) ranavirus infections, we tested for presence of ranavirus infections among sympatric larval am ...

Abstract:
... Coxiella burnetii is the etiologic agent of the zoonotic disease Q fever and is considered to be endemic in domestic ruminants. Small ruminants in particular are important reservoirs for human infection. Serologic and molecular methods are both available for diagnosis of infection with C. burnetii, but there has been little research evaluating the prevalence of this organism in small ruminants out ...

Abstract:
... Ranaviruses are significant pathogens of amphibians, reptiles, and fishes, contributing to mass mortality events worldwide. Despite an increasing focus on ranavirus ecology, our understanding of ranavirus transmission, especially among reptilian hosts, remains limited. For example, experimental evidence for oral transmission of the virus in chelonians is mixed. Consequently, vector-borne transmiss ...
