| nasal and cloacal bacteria in free-ranging desert tortoises from the western united states. | aerobic bacteria were collected from three free-ranging desert tortoise (gopherus agassizii) populations in the eastern mojave desert (arizona, utah; usa) from 1989 to 1993, and from two free-ranging populations in the central sonoran desert (arizona, usa) from 1990 to 1994. six species of nasal bacteria and 18 species of cloacal bacteria were identified. at least one potential pathogen was found in the nasal cavity (pasteurella testudinis), and at least two potential pathogens in the cloaca (ps ... | 2001 | 11310875 |
| histomorphometric studies of dermal bone in the desert tortoise, gopherus agassizii. | dermal bone biopsies were collected from the periphery of the carapaces of adult desert tortoises (gopherus agassizii) from grazed and ungrazed habitats near the arizona/utah border (usa). quantitative bone histomorphometry was performed on these biopsies as well as on dermal bone biopsies collected from captive juvenile desert tortoises. except for mild osteomalacia, carapaces of adult desert tortoises from the grazed habitat were relatively normal. no signs of osteopenia were observed. based o ... | 1992 | 1474659 |
| mycoplasmosis in free-ranging desert tortoises in utah and arizona. | upper respiratory tract disease (urtd) has been associated with major losses of free-ranging desert tortoises (gopherus agassizii) in the southwestern united states. this prompted a clinical examination of 63 free-ranging desert tortoises for signs of urtd and sampling for mycoplasma agassizii, the causative agent of urtd. tortoises were sampled from three sites in the eastern mojave desert (1992-93), and from three sites in the sonoran desert (1992-94). plasma samples were tested for antibodies ... | 2005 | 16456181 |
