Testudinidae A chronic upper respiratory tract disease (URTD) of desert tortoises, Gopherus agassizii, is thought to have contributed to population declines over parts of that species' natural ranges during the past two decades (Department of Interior 1990; Jacobson, et ai, 1991; Corn 1994; United States Fish and Wildlife Service, 1994). The disease is characterized clinically by serous, mucous, or purulent nasal and ocular discharge, conjunctivitis and palpebral edema, and histopathologically by infiltration of inflammatory cells accompanied by hyperplasia and degeneration of upper respiratory tract epithelium (Brown, et ai, 1994; Jacobson, et ai, 1995). Reported population declines in the westem Mojave Desert led to the desert tortoise being listed as a threatened species by the United States Department of Interior in 1990 (Department of Interior, 1990). Similar signs of disease have been seen in free-ranging gopher tortoises, Gopherus polyphemus, (McLaughlin, et ai, 2000) which have legal protection as a "species of special concern" in Florida, and in a variety of species of captive chelonians (Jacobson, et aI, 1991). A previously undescribed species of mycoplasma, Mycoplasma agassizii, proposed species novum, was cultured from nasal lavages of affected tortoises, and shown by experimental infection studies of desert tortoises (Brown, et aI, 1994) and gopher tortoises (Brown, et ai, 1999) to be an etiologic agent of URTD.
