An adult Bengal tiger (Panthera tigris tigris) housed in an outdoor sanctuary in Florida exhibited vomiting, diarrhea, and weight loss. A clinical workup did not reveal the source of the clinical signs and antibiotic therapy was unrewarding. Radiographs revealed the presence of an abdominal mass. The tiger died during an immobilization for a follow-up clinical examination. A necropsy was performed and tissue samples of intestine and mesenteric lymph nodes were submitted for histopathologic diagnosis. A pyogranulomatous panenteritis and lymphadenitis with intralesional hyphae led to a presumptive etiologic diagnosis of intestinal/abdominal pythiosis. The diagnosis of pythiosis was confirmed by serology and immunoblotting. 相似文献

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. 相似文献

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 retraction. The animal recovered normal ambulatory function 6 wk after surgery. 相似文献

Disseminated infection with Histoplasma capsulatum was diagnosed in a 7-yr-old female Bengal tiger (Panthera tigris). Clinical signs were nonspecific with the exception of brief periods of tachypnea for 5 days prior to death. H. capsulatum organisms were found in the lungs, tracheobronchial lymph nodes, and liver. Diagnosis was confirmed by tracheal wash, urine H. capsulatum enzyme immunoassay, and necropsy results. This report represents the first published account of disseminated histoplasmosis in a tiger. 相似文献

An adult, captive-born Sumatran tiger (Panthera tigris sumatrae) had been ataxic for approximately 3 mo and had been self-mutilating after an acute onset of unilateral paresis and Homer's syndrome. Histologic lesions in the cervical spinal cord were consistent with fibrocartilaginous embolic myelopathy (FCEM), and they included the presence of cartilaginous occlusion of spinal blood vessels. This is the first reported case of FCEM in a large felid and specifically a Sumatran tiger. 相似文献

A captive 9-yr-old female Siberian tiger (Panthera tigris altaica) at the Lisbon Zoo was treated with equine chorionic gonadotropin followed 80 hr later by human chorionic gonadotropin to stimulate follicular development and ovulation, respectively. Forty-one hours after the second hormone administration, the tiger was subjected to transvaginal artificial insemination with diluted fresh semen containing 500 x 10(6) motile spermatozoa obtained from an 8-yr-old male Siberian tiger via electroejaculation. After anesthesia, the female tiger was placed in an inclined position with the hind limbs elevated during and after the insemination and was maintained in this position for 15 min to minimize semen reflux. An anesthetic reversal agent was then administered. After a 103-day gestation, the female gave birth to three apparently healthy cubs that survived 24-48 hr. These results demonstrate that transvaginal artificial insemination can be successfully performed in the Siberian tiger to produce full-term offspring. 相似文献

A 19-year-old female Bengal tiger (Panthera tigris tigris) was presented
with hind limb weakness, ataxia and respiratory distress. Computed tomography revealed a
mass between the left side of the T7 vertebra and the base of the left 7th rib. The tiger
then died, and necropsy was performed. Grossly, the vertebral mass was 6 × 5.7 × 3 cm, and
invaded the adjacent vertebral bone and compressed the T7 spinal cord. Histologically, the
mass was composed of large, clear, vacuolated and polygonal cells with osteochondral
matrix. Cellular and nuclear atypia were moderate. The vacuolated cells stained positively
for cytokeratin and vimentin and negatively for S-100. Based on these findings, the
present case was diagnosed as a vertebral chordoma; the first report in a tiger. 相似文献

A 17-year-old Bengal tiger (Panthera tigris) presented with dyspnea and tachypnea. Radiographs revealed severe pleural and pericardial effusion, but no obvious mass. During attempts to remove the fluid under anesthesia, the cat developed cardiac tamponade and died. At necropsy, a nodular mass was found at the heart base and was identified as a pericardial mesothelioma. This is the first report of this tumor in any large cat. 相似文献

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. 相似文献

Diseases of the coxofemoral (hip) joint are infrequently diagnosed in horses. Most cases are presented as an unilateral condition and usually are of traumatic origin. This case report describes a Friesian foal with a clinically obvious thoracolumbar kyphosis, combined with a weight‐shifting stance and a shortened stride of both hindlimbs. General clinical and lameness examinations, computed tomographic examination of the pelvis, and macroscopic and histopathological examinations of the coxofemoral joints were performed. This revealed a final, phenotypical diagnosis of a primary osteochondral dysplasia of both coxofemoral joints with secondary osteoarthritis. Similar to the occurrence of this condition in other species and considering the small genetic basis of the Friesian horse breed, a genetic predisposing factor is suspected to play a key role in the developing mechanism of dysplastic coxofemoral joint disease in horses as illustrated with this case. Computed tomography scanning appears to be a useful imaging technique in the detection of coxofemoral joint disease in small horses and foals. 相似文献

An 18-yr-old Bengal tiger (Panthera tigris) presented with acute onset hind limb paresis. Radiographic and ultrasonographic imaging revealed a caudal abdominal aortic thrombus and a cranial mediastinal mass. Necropsy confirmed aortic thrombosis. Necrotizing enteritis and multifocal renal thrombosis were also noted. The cranial mediastinum contained a bilobed mass that histologically and ultrastructurally was consistent with a carcinoid. 相似文献

Therapy for pyothorax, or pleural empyema, has not been described for large felids. This case describes the successful treatment of pyothorax in a captive, large felid. A 15-yr-old multiparous, female Amur tiger (Panthera tigris altaica) presented with nonspecific clinical signs caused by an insidious onset of pyothorax. Management of pyothorax cases in companion animals often involves thoracostomy tube placement with recurrent drainage of the pleural cavity, intensive supportive care, and monitoring. In this case, conservative management was elected because hospitalization was not a viable option. Thoracocentesis was performed to drain as much fluid from the chest cavity as possible, yielding more than 1.3 L. Corynebacterium sp. and unidentified anaerobic gram-positive cocci were cultured. Treatment included cefovecin subcutaneously, oral antibiotic therapy with clindamycin and marbofloxacin, meloxicam, and restricted exercise by minimizing access to the main exhibit. Significant improvement was noted clinically and radiographically 6 wk later, and no relapses were noted in the following weeks. An examination 11.5 mo later confirmed resolution. 相似文献

Three Sumatran tigers (Panthera tigris sumatrae) at the Heidelberg Zoo in Germany presented with severe neurologic signs. Physical examination and diagnostic tests did not reveal a definitive diagnosis. Two days after initial presenting signs, all of the animals appeared clinically normal. An investigation into this outbreak revealed that all animals received horse meat on the evening before the incident. A toxicologic examination was initiated and serum analysis of the affected female tiger cub and the horse meat revealed contamination with pentobarbital. 相似文献

Pyelonephritis, in which Staphylococcus intermedius was isolated, was diagnosed in a 4-year-old female Siberian tiger (Panthera tigris altaica). At necropsy, the renal pelvis was dilated with a large amount of purulent exudates. Microscopically, the lesions of renal pelvis and medulla consisted of necrotic foci intermingled primarily with numerous degenerative neutrophils and a few lymphocytes, plasma cells and macrophages. Bacteriology showed the presence of S. intermedius. This is the first report on pyelonephritis associated with S. intermedius in wild felidae. 相似文献

Preductal aortic coarctation and patent ductus arteriosus are described in a neonatal Sumatran tiger, Panthera tigris sumatrae. Eight days postpartum, the cub appeared weak, and it was separated from the dam for hand rearing. On examination it was dehydrated and hypothermic. Despite treatment, the animal's condition worsened and the cub died 12 days postpartum. Gross postmortem and histologic examinations revealed a preductal aortic coarctation and patent ductus arteriosus with a patent foramen ovale and moderate dilatation of the right ventricle of the heart. Focal pneumonia and mild hepatitis were also present; however, diffuse pulmonary congestion and edema were considered to be the proximate cause of death. 相似文献

Fibroblast cultures of a skin biopsy from an adult intact male Siberian tiger (Panthera tigris altaica) revealed an abnormal standard and G-banded karyotype diploid chromosome number of 2n = 39 XXY due to an extra sex chromosome as opposed to the expected 2n = 38 XY. The tiger was euthanatized 1 yr later due to acute multifocal intervertebral disc disease. Histopathology of the reproductive tract demonstrated a paucity of seminiferous tubules and these were devoid of spermatagonia. An increase in fibrous connective tissue was noted in sections of the prostate and epididymis, and expansion of the fibrous interstitium was observed in the testes. 相似文献

A 13-yr-old Amur tiger (Panthera tigris altaica) was presented for an acute onset of paraplegia. Spinal imaging that included plain radiographs, myelography, and computed tomography performed under general anesthesia revealed lateralized spinal cord compression at the intervertebral disc space L4-5 caused by intervertebral disc extrusion. This extrusion was accompanied by an extensive epidural hemorrhage from L3 to L6. Therefore, a continuous hemilaminectomy from L3 to L6 was performed, resulting in complete decompression of the spinal cord. The tiger was ambulatory again 10 days after the surgery. This case suggests that the potential benefit of complete spinal cord decompression may outweigh the risk of causing clinically significant spinal instability after extensive decompression. 相似文献
