Eight free-ranging timber rattlesnakes (Crotalus horridus) from two geographically isolated Massachusetts populations were observed with skin lesions located primarily on the head but occasionally also on the lateral and ventral surfaces of the body. The snakes underwent health assessments that included physical examination, clinical pathology, full body radiographs, and full thickness biopsies of skin lesions. Each snake had fungal elements present histologically in tissue sections from skin lesions. Ophidiomyces ophiodiicola was identified from skin lesions using polymerase chain reaction in all eight snakes.
Results suggested that administration of meloxicam at a dose of 0.2 mg/kg IV or PO in green iguanas would result in plasma concentrations > 0.1 μg/mL for approximately 24 hours.
By use of a 2.7-mm rigid endoscope, liver biopsy procedures can be performed safely, swiftly, and easily in green iguanas. Biopsy specimens obtained by this technique are suitable for histologic examination. For evaluation of the liver and biopsy specimen collection in lizards, endoscopy is recommended.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
