| clinical disease and laboratory abnormalities in free-ranging desert tortoises in california (1990-1995). | desert tortoise (gopherus agassizii) populations have experienced precipitous declines resulting from the cumulative impact of habitat loss and human and disease-related mortality. diagnosis of disease in live, free-ranging tortoises is facilitated by evaluation of clinical signs and laboratory test results but may be complicated by seasonal and environmental effects. the goals of this study were: 1) to describe and monitor clinical and laboratory signs of disease in adult, free-ranging desert t ... | 2003 | 12685067 |
| comparison of current methods for the detection of chronic mycoplasmal urtd in wild populations of the mojave desert tortoise (gopherus agassizii). | pathogens that cause subclinical diseases or exhibit low infection intensities are difficult to quantify in wild populations. mojave desert tortoises ( gopherus agassizii ) have been the focus of much research aimed at measuring the presence of upper respiratory disease (urtd) and urtd-associated pathogens, and techniques used to quantify disease in gopherus species have also been used for disease surveillance in other species of turtles and tortoises of conservation concern. published surveys o ... | 2017 | 27788056 |
| seroepidemiology of upper respiratory tract disease in the desert tortoise in the western mojave desert of california. | several factors have combined with an upper respiratory tract disease (urtd) to produce declines on some population numbers of desert tortoises (gopherus agassizii) in the western usa. this study was designed to determine the seroepidemiology of urtd in a population of wild adult tortoises at the desert tortoise research natural area (dtna) study site in kern county (california, usa). prior to initiation of the study, there was a dramatic decline in the number of individuals in this population. ... | 1999 | 10574531 |
