Mycoplasma testudineum in free-ranging desert tortoises, Gopherus agassizii.
We performed clinico-pathological evaluations of 11 wild Agassiz's desert tortoises (Gopherus agassizii) from a translocation project in the central Mojave Desert, California, USA. Group 1 consisted of nine tortoises that were selected primarily due to serologic status, indicating exposure to Mycoplasma testudineum (seven) or both M. agassizii and M. testudineum (two), and secondarily due to cl...
متن کاملPopulation pharmacokinetics of a single intramuscular administration of tulathromycin in adult desert tortoises (Gopherus agassizii).
Tulathromycin, a long acting macrolide antibiotic, has demonstrated efficacy against respiratory pathogens including Mycoplasma bovis and M. hyopneumoniae. A pharmacokinetic study was performed to evaluate the clinical applicability of tulathromycin in desert tortoises following a single intramuscular dose of 5 mg/kg. A single blood sample was collected from 110 different desert tortoises at 0....
متن کاملMycoplasma agassizii in Morafka's desert tortoise (Gopherus morafkai) in Mexico.
We conducted health evaluations of 69 wild and 22 captive Morafka's desert tortoises (Gopherus morafkai) in Mexico between 2005 and 2008. The wild tortoises were from 11 sites in the states of Sonora and Sinaloa, and the captive tortoises were from the state-managed Centro Ecológico de Sonora Zoo in Hermosillo and a private residence in the town of Alamos. We tested 88 tortoises for mycoplasmal...
متن کاملDesert Tortoises (Gopherus agassizii) Are Selective Herbivores that Track the Flowering Phenology of Their Preferred Food Plants
Previous studies of desert tortoise foraging ecology in the western Mojave Desert suggest that these animals are selective herbivores, which alter their diet according to the temporal availability of preferred food plants. These studies, however, did not estimate availability of potential food plants by taking into account the spatial and temporal variability in ephemeral plant abundance that o...
متن کاملDesert Tortoise (Gopherus agassizii) Dietary Specialization Decreases across a Precipitation Gradient
We studied the plant resource use between and within populations of desert tortoise (Gopherus agassizii) across a precipitation gradient in the Sonoran Desert of Arizona. The carbon and nitrogen stable isotope values in animal tissues are a reflection of the carbon and nitrogen isotope values in diet, and consequently represent a powerful tool to study animal feeding ecology. We measured the δ(...
