phylogeography and genetic ancestry of tigers (panthera tigris).eight traditional subspecies of tiger (panthera tigris),of which three recently became extinct, are commonly recognized on the basis of geographic isolation and morphological characteristics. to investigate the species' evolutionary history and to establish objective methods for subspecies recognition, voucher specimens of blood, skin, hair, and/or skin biopsies from 134 tigers with verified geographic origins or heritage across the whole distribution range were examined for three molecular mark ...200415583716
survey of transport environments of circus tigers (panthera tigris).the type of equipment used to transport circus tigers, environmental factors experienced during transport, and resultant body temperatures of tigers transported were surveyed during hot and cold weather conditions with six different circus tiger acts. dataloggers recorded interior and exterior temperatures, relative humidity, and radiant heat at 5-min intervals during each trip. microdataloggers fed to the tigers recorded body temperature and were recovered from eight bengal (panthera tigris tig ...200415305511
persistent right aortic arch and aberrant left subclavian artery in a white bengal tiger (panthera tigris).a 3-mo-old male white bengal tiger (panthera tigris) presented with the chief complaint of regurgitation of solid food since weaning at 2 mo of age. compared with its littermates, the tiger was in poor body condition and weighed only 10.3 kg when its littermates were estimated at 20-25 kg. thoracic radiographs showed a megaesophagus cranial to the heart base. a contrast esophagram more clearly outlined the megaesophagus, and fluoroscopy demonstrated normal motility of the caudal esophagus. endos ...200112790433
combination therapy for footpad lesions in a captive bengal tiger (panthera tigris tigris).a captive adult male bengal tiger (panthera tigris tigris) was treated for chronic footpad ulcers associated with pacing on concrete cage surfaces. combination therapy of oral fluoxetine and acepromazine administration to diminate pacing behavior, daily application of moisturizing ointment, and oral vitamin e supplementation resulted in complete resolution of all footpad lesions. subsequent clinical episodes completely resolved with similar treatments.200212564540
nasopharyngeal myxosarcoma in a bengal tiger (panthera tigris).an 18- to 25-yr-old intact female bengal tiger (panthera tigris) was diagnosed antemortem and postmortem with nasopharyngeal myxosarcoma metastatic to the lung, chronic lymphoplasmacytic otitis media, and lymphoplasmacytic and eosinophilic stomatitis. myxosarcomas are rare in domestic animals and seldom metastasize; this tumor has not been previously reported in an exotic felid. computed tomography of the skull was used during the diagnoses.200212564536
caudal cervical disc protrusion in a bengal tiger (panthera tigris tigris).a young adult male white bengal tiger (panthera tigris tigris) presented with hindlimb ataxia. cervical and lumbar myelography revealed a compressive lesion of the cord at c(6-7). corticosteroid therapy and confinement failed to provide lasting remission of signs. a modified, inverted cone ventral slot decompression was used to remove the fibrous material causing cord compression at c(6-7). temporary horner's syndrome and laryngeal paresis developed postsurgically because of excessive tissue ret ...200011237151
immunohistochemical study of pancreatic neuroendocrine tumor in panthera tigris tigris.the histological and immunohistochemical characteristics of a case of pancreatic neuroendocrine tumor are described in a 14-yr-old female bengal tiger (panthera tigris tigris) housed at the new biblical zoo of jerusalem, jerusalem, israel, 1994. the neoplastic cells were immunohistochemically negative for insulin and glucagon, slightly positive for neuron-specific enolase, moderately positive for serotonin and somatostatin, and markedly positive for chromogranine a and gastrin. this is the first ...19968827685
meniscal ossification. ii. the normal pattern in the tiger knee.examination of knee menisci of bengal tigers revealed ossicles within the cartilaginous anterior horn of each medial meniscus. this ossification was not evident in the neonatal animal, but was present in animals aged 20 months or older. the ossicle appeared prior to the completion of skeletal maturation at the knee, and was composed of normal remodeling trabecular bone. while most animals had a single, variably sized ossicle, multiple ossicles also occurred. the meniscal cartilage apposed to the ...19947517071
yohimbine hydrochloride reversal of ketamine hydrochloride and xylazine hydrochloride immobilization of bengal tigers and effects on hematology and serum chemistries.six bengal tigers (panthera tigris tigris) were immobilized five times at 2-wk intervals with ketamine hydrochloride (ketamine) and xylazine hydrochloride (xylazine) mixtures at different dose levels. hematology and serum chemistry analyses on blood samples collected at each immobilization remained normal during the study. there were acute changes in hematocrit, chloride, potassium, glucose, and bilirubin as a function of xylazine dose level. the effect of yohimbine hydrochloride (yohimbine) on ...19873586208
