The eye of the Barbary sheep or aoudad (Ammotragus lervia): reference values for selected ophthalmic diagnostic tests, morphologic and biometric observations
The purpose of this study was to describe the normal ocular anatomy and establish reference values for ophthalmic tests in the Barbary sheep or aoudad (Ammotragus lervia). Aoudad eyes are large and laterally positioned in the head with several specialized anatomic features attributed to evolutionary adaptations for grazing. Normal values for commonly used ophthalmic tests were established, Schi...
متن کاملBalantidiasis in the gastric lymph nodes of Barbary sheep (Ammotragus lervia): an incidental finding
A 4-year-old female Barbary sheep (Ammotragus lervia) was found dead in the Gwangju Uchi Park Zoo. The animal had previously exhibited weakness and lethargy, but no signs of diarrhea. The carcass was emaciated upon presentation. The main gross lesion was characterized by severe serous atrophy of the fat tissues of the coronary and left ventricular grooves, resulting in the transformation of the...

AIM This study is part of an active surveillance program for monitoring animal health status in endangered species, and was conducted to screen captive Barbary sheep (Ammotragus lervia) for hemoplasma infection. MATERIALS AND METHODS A total of 12 blood samples were collected, DNA extracted and further tested by a pan-hemoplasma polymerase chain reaction protocol. RESULTS Animals were clini...
متن کاملVariation of Meiotic Recombination Rates and MLH1 Foci Distribution in Spermatocytes of Cattle, Sheep and Goats
Despite similar genome sizes, a great variability in recombination rates is observed in mammals. We used antibodies against SYCP3, MLH1 and centromeres to compare crossover frequency, position along chromosome arms and the effect of crossover interference in spermatocytes of 4 species from the family Bovidae ( Bos taurus , 2n = 60, tribe Bovini; Ovis aries , 2n = 54, Capra hircus , 2n = 60 and ...
متن کاملPhylogeographic Patterns in Mitochondrial Dna of the Ostrich (struthio Camelus)
--We assayed restriction-site differences in mitochondrial DNA (mtDNA) within and among populations of the Ostrich (Struthio camelus) throughout much of its African distribution. Little genetic diversity was evident among samples drawn from localities throughout southern Africa (S.c. australis), while deep divisions in the mtDNA gene tree exist between representatives of the eastern (S.c. molyb...
