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… 
MYCOPLASMA AGASSIZII IN THE SONORAN POPULATION OF THE DESERT TORTOISE IN ARIZONA
TLDR
The purpose of this study was to determine the prevalence of URTD across an urban gradient in Greater Tucson, Arizona, the relationship between URTd and captive and free-ranging tortoises in Mohave, Maricopa, and Pima counties in Arizona, and the effects of U RTD on desert tortoise home range size and winter temperature selection.
EFFECTS OF MYCOPLASMAL UPPER RESPIRATORY TRACT DISEASE ON MORBIDITY AND MORTALITY OF GOPHER TORTOISES IN NORTHERN AND CENTRAL FLORIDA
TLDR
Mycoplasmal URTD is believed to be a chronic disease with high morbidity but low mortality, and follow-up studies are needed to detect long-term effects.
CLINICAL DISEASE AND LABORATORY ABNORMALITIES IN FREE-RANGING DESERT TORTOISES IN CALIFORNIA (1990–1995)
TLDR
The severe disease prevalence in Goffs tortoises likely contributed to the population decline that occurred during and subsequent to this study, and the utility of diagnostic tests in predicting morbidity and mortality was assessed.
Mycoplasmosis and upper respiratory tract disease of tortoises: a review and update.
Seasonal Variations in Microbial Communities in the Nasal Passages of Captive Desert Tortoises
TLDR
It is indicated that the nasal passages of desert tortoises contain large continuously changing communities of bacteria and suggests that further analysis of these microorganisms may be useful in assessing the health or stress of populations of desert Tortoises and the susceptibility of individual tortOises to URTD.
Prevalence and Diversity of the Upper Respiratory Pathogen Mycoplasma agassizii in Mojave Desert Tortoises (Gopherus agassizii)
TLDR
This is the first range-wide study of the presence of the pathogen, M. agassizii, in Mojave Desert Tortoises, and uses published lines of evidence to discuss the roles of rare transmission events and long-term mycoplasmal persistence in individual hosts on tortoise URTD dynamics.
MYCOPLASMA AGASSIZII IN MORAFKA'S DESERT TORTOISE (GOPHERUS MORAFKAI) IN MEXICO
TLDR
It is found that URTD is an important disease in captive tortoises and if they escape or are released by intention or accident to the wild, captive Tortoises are likely to pose risks to healthy, naïve wild populations.
Paramyxovirus Infection in a Leopard Tortoise (Geochelone pardalis babcocki) with Respiratory Disease
ABSTRACT Paramyxoviruses (PMVs) are well documented as a cause of respiratory disease in snakes, but they have only been documented in tortoises in a very few cases. This study describes a leopard

Mycoplasma agassizii causes upper respiratory tract disease in the desert tortoise
TLDR
It is concluded that M. agassizii is an etiologic agent of URTD in the desert tortoise.
RELATIONSHIP BETWEEN CLINICAL SIGNS OF UPPER RESPIRATORY TRACT DISEASE AND ANTIBODIES TO MYCOPLASMA AGASSIZII IN DESERT TORTOISES FROM NEVADA
TLDR
Serologic testing for M. agassizii antibodies supported clinical signs as useful indicators of URTD, but it also detected potential subclinical infection in 34 (34%) of 99 animals without clinical signs.
Detection of antibodies to a pathogenic mycoplasma in desert tortoises (Gopherus agassizii) with upper respiratory tract disease
TLDR
An enzyme-linked immunosorbent assay (ELISA) developed with a monoclonal antibody with specificity for desert tortoise immunoglobulin light chain proved that the ELISA reliably diagnosed M. agassizii-induced upper respiratory tract disease in free-ranging desert tortoises.
CHRONIC UPPER RESPIRATORY TRACT DISEASE OF FREE-RANGING DESERT TORTOISES (XEROBATES AGASSIZII)
TLDR
While no significant differences were found for concentrations of lead, copper, cadmium, and selenium, the livers of ill tortoises had higher concentrations of mercury and iron, and Lesions were found consistently in the upper respiratory tract (URT) of ill Tortoise.
ECOLOGICAL ENERGETICS OF THE DESERT TORTOISE (GOPHERUS AGASSIZII): EFFECTS OF RAINFALL AND DROUGHT'
TLDR
Energy acquisition and expenditure in desert tortoises are thus strongly constrained by the contingencies of rainfall, both indirectly through effects on availability and quality of food, and directly through reliance on free-standing water for drinking, which is apparently necessary for achieving a net annual energy profit.
Enhanced isolation of Mycoplasma pneumoniae from throat washings with a newly-modified culture medium.
TLDR
The findings suggest that these procedures might be effectively applied to the recovery of M. pneumoniae from all likely host and that improved recovery of the organism may aid in the interpretation of a number of puzzling questions about the epidemiology of M., pneumoniae infections.
Taxonomic analysis of the tortoise mycoplasmas Mycoplasma agassizii and Mycoplasma testudinis by 16S rRNA gene sequence comparison.
TLDR
The 16S rRNA gene of Acholeplasma laidlawii was similarly detected in a tortoise isolate, showing that diverse mollicutes can share the same family of reptilian host.
