Abstract:
... Intranuclear coccidia and Mycoplasma spp. were identified from the nasal cavity of 5 Sulawesi tortoises (Indotestudo forsteni) affected by chronic rhinosinusitis and oronasal fistulae. This study provides the first antemortem diagnosis of intranuclear coccidiosis in tortoises and the first cytomorphologic descriptions of this disease. Histopathologic and ultrastructural morphology of the intranucl ...

Abstract:
... Iridoviruses, pathogens typically associated with fish and amphibians, have recently been shown to cause acute respiratory disease in chelonians including box turtles, red-eared sliders, gopher tortoises, and Burmese star tortoises. Case reports of natural infections in several chelonian species in the United States have been reported, however the prevalence remains unknown in susceptible populati ...
