Testudinidae Gopherus berlandieri Upper respiratory tract disease (URTD) caused by Mycoplasma agassizii is characterized by ocular and nasal discharge, conjunctivitis and decreased appetite and lethargy. Significant morbidity and mortality can be caused by the secondary effects of this disease including generalized malaise and decreased visual and olfactory function. URTD has been associated with major losses of free-ranging desert tortoises (Gopherus agassizii) and gopher tortoises (Gopherus polyphemus) in the United States. This has prompted investigation into the prevalence and distribution of the disease in the Texas tortoise (Gopherus berlandieri). Blood samples were taken from 40 Texas tortoises, from May – October 2009, for detection of antimycoplasma antibodies by ELISA. Of the 40 tortoises, 11 (27.5%) were seropositive indicating that they had been exposed to mycoplasma and developed a detectable immune response. Twenty-six of the tortoises were seronegative (65%), and three (7.5%) were suspect for antibodies against M. agassizii on the ELISA test. Seropositive tortoises were found on both public and private lands in Cameron and Hidalgo counties of south Texas. Nasal lavage samples were collected for culture and detection of Mycoplasma agassizii gene sequences by polymerase chain reaction (PCR). Of the 35 tortoises that had nasal lavage performed, only one was positive on culture and PCR for Mycoplasma organisms. Overall, the observed Texas tortoises appeared clinically healthy. Further studies are needed to determine the overall impact of URTD caused by Mycoplasma agassizii on populations of Texas tortoise.
