Fourteen cases of dermatophytosis were identified from medical records of red pandas (Ailurus fulgens fulgens) housed at the Knoxville Zoo between 1980 and 1996. The median age of affected animals on initial presentation was 8.5 wk (3 wk-11 mo). Clinical signs included crusting, purulent exudate, alopecia, thickening of affected skin, ulceration, and necrosis. Seven animals had mild lesions with signs restricted to crusting and/or alopecia, and six animals had more severe infections, with ulceration, skin necrosis, and purulent exudate. Five of the severely affected pandas had tail involvement. The severity of disease affecting one individual was not recorded. Dermatophytosis was confirmed by culture, cytology, histopathology, or culture followed by histopathology. Microsporum gypseum was the only fungal organism cultured. Six animals were treated for mild disease, and all clinical signs resolved. Partial tail amputation was required as part of the treatment regimen for two of the six severely affected animals, and two others had ulcerated tail lesions that left circumferential scarring after resolution of infection. Itraconazole (5 mg/kg p.o. q 12-24 hr) was the most frequently used systemic antifungal agent in animals with severe lesions. All fungal infections resolved, although one panda died from unrelated causes early in the treatment period.  相似文献

A debilitated 9-yr-old female red panda (Ailurus fulgens fulgens) with a recent history of corticosteroid administration displayed anorexia, depression, and diarrhea for 2 days. Blood work revealed a moderate nonregenerative anemia, leukocytosis, hypokalemia, hyperbilirubinemia, and mildly elevated alanine aminotransferase and aspartate aminotransferase. Serology was negative for occult heartworm, Toxoplasma gondii, feline leukemia virus, feline infectious peritonitis, feline immunodeficiency virus, and canine distemper virus. Electron microscopy of the feces demonstrated corona-like virus particles. The panda died 3 days after initial presentation. Histologic findings included multifocal, acute, hepatic necrosis and diffuse, necrotizing colitis. Liver and colon lesions contained intracellular, curved, spore-forming, gram-negative, silver-positive rods morphologically consistent with Clostridium piliforme. This panda most likely contracted Tyzzer's disease subsequent to having a compromised immune system after corticosteroid administration and concurrent disease.  相似文献

小熊猫(Ailurus fulgens)是亚洲特有的濒危动物。由于圈养小熊猫活动空间受限、环境单调等因素,时常有刻板行为表现。本研究依据小熊猫自然行为特性及动物福利要求,以环境、食物、气味等因素进行多重丰容,观察频繁出现刻板行为的2只圈养小熊猫个体的行为修正效果。应用聚集动物取样法,从9:00到17:00,全事件记录并观察小熊猫行为。观察发现,受试小熊猫主要表现摇晃与踱步两种刻板行为。通过丰容前与三个阶段的丰容后刻板行为发生率比较,丰容后的刻板行为均显著低于丰容前,而探究行为和修饰行为有所增加。由此可见,多重丰容可以减少圈养小熊猫刻板行为的发生,促进自然行为的表达。  相似文献

本试验旨在研究小熊猫胃肠道菌群多样性。采用聚合酶链式反应(PCR)-变性梯度凝胶电泳(DGGE)技术结合条带的克隆测序、聚类分析和主成分分析(PCA)检测小熊猫胃肠道菌群结构及多样性。结果表明:1)PCR-DGGE图谱显示小熊猫胃肠道中有大量菌群,且不同部位的菌群结构存在一定的差异,相邻肠段菌群结构具有一定的相似性。结肠和粪便样品的菌群多样性较高,其次为胃和直肠样品,而空肠和回肠样品菌群多样性较低。2)小熊猫胃肠道菌群PCR-DGGE图谱中测序的条带大多数归为厚壁菌门(Firmicutes)、拟杆菌门(Bacteroides)、变形菌门(Proteobacteria)和疣微菌门(Verrucomicrobia),共性条带主要是未培养拟杆菌门细菌(uncultured Bacteroidetes bacterium)、粪肠球菌(Enterococcus faecalis)、未培养梭状芽孢杆菌(uncultured Clostridium sp.)、乳酸乳球菌(Lactococcus lactis)和食窦魏斯氏菌(Weissella cibaria),其中厚壁菌门为优势菌群;特异性条带主要是丛毛单胞菌(Comamonas sp.)、梭菌属(Clostridium sp.)和Akkermansia。由此可见,小熊猫胃肠道中栖息着大量菌群,且其多样性按照胃肠道由前至后的顺序呈现高-低-高的趋势。  相似文献

Two adult North American river otters (Lontra canadensis) and an adult red panda (Ailurus fulgens fulgens) at three separate institutions died within 22 hr after receiving single 2.5- to 2.7-mg/kg doses of melarsomine dihydrochloride administered in the epaxial musculature as a treatment for filarid nematodes. One otter had a suspected Dirofilaria immitis infection, the other had a confirmed D. lutrae infection, and the red panda had a confirmed Dirofilaria sp. infection, presumably with D. immitis. Postmortem examinations revealed similar gross lesions, although they were less severe in the red panda. The trachea and primary bronchi contained abundant foamy fluid, the lungs were mottled with areas of consolidation, and the pulmonary parenchyma exuded abundant fluid at the cut section. Histologic evaluation revealed acute pulmonary edema, which resulted in respiratory failure and death. There may have been direct pulmonary cellular toxicity of melarsomine dihydrochloride or a severe systemic anaphylactic reaction to antigens released after parasite death. An idiosyncratic drug reaction or a low therapeutic index of melarsomine probably caused the death of the three individuals. Melarsomine dihydrochloride use should be avoided in North American river otters and red pandas.  相似文献

Three adult red pandas (Ailurus fulgens) developed multiple periarticular exostoses in their elbow joints. Two of these animals also had extensive periosteal new bone formation and osteosclerosis of the ulnae and radii and mild periosteal new bone deposition on the femurs. One animal also showed extensive hyperostosis of the cranium and mandibles. Dietary concentrations of calcium and phosphorus were estimated to be adequate, but dietary vitamin A and D appeared excessive when compared with recommended levels for this species. Serum vitamin A concentrations were not elevated in the two most severely affected animals, but their liver vitamin A content was higher than what is considered normal for most domestic animal species. Serum 25-hydroxy vitamin D concentrations were within normal ranges for domestic species. A definitive diagnosis for the cause of the lesions was not established, but hypervitaminosis A was suspected.  相似文献

Chromobacteriosis in a Chinese red panda (Ailurus fulgens styani).   总被引:1,自引:0,他引:1  
An adult Chinese red panda (Ailurus fulgens styani) transported by airplane from Florida to a North Dakota zoo died 1 week after arrival. Grossly, an interscapular abscess, subcutaneous inflammation, lymphadenitis, and pulmonary abscesses were observed. Microscopic findings included necrotizing inflammation in liver, lung, lymph node, and spleen. Chromobacterium violaceum was cultured from the interscapular abscess, liver, lung, and spleen and was injected into Swiss Webster mice. These mice died 18 hours postinoculation, and C. violaceum was cultured from liver, lung, and spleen. Chromobacterium violaceum is a sporadically reported but highly virulent pathogenic bacterium of both animals and humans typically found as a soil and water inhabitant of tropical and subtropical regions.  相似文献

Conservation strategies for the giant panda (Ailuropoda melanoleuca) include the development of a self-sustaining ex situ population. This study examined the potential significance of infectious pathogens in giant pandas ex situ. Serologic antibody titers against canine distemper virus (CDV), canine parvovirus (CPV), canine adenovirus (CAV), canine coronavirus (CCV), canine herpesvirus, canine parainfluenza virus (CPIV), Toxoplasma gondii, Neospora caninum, and Leptospira interrogans were measured in 44 samples taken from 19 giant pandas between 1998 and 2003 at the Chengdu Research Base of Giant Panda Breeding in Sichuan, China. Seroassays also included samples obtained in 2003 from eight red pandas (Ailurus fulgens) housed at the same institution. All individuals had been vaccinated with a Chinese canine vaccine that included modified live CDV, CPV, CAV, CCV, and CPIV. Positive antibody titers were found only against CDV, CPV, and T. gondii. Sera were negative for antibodies against the other six pathogens. Results indicate that the quality of the vaccine may not be reliable and that it should not be considered protective or safe in giant pandas and red pandas. Positive antibody titers against T. gondii were found in seven of the 19 giant pandas. The clinical, subclinical, or epidemiologic significance of infection with these pathogens via natural exposure or from modified live vaccines in giant pandas is unknown. Research in this area is imperative to sustaining a viable population of giant pandas and other endangered species.  相似文献

The densitometric and mechanical structural properties of the left and right fifth metacarpal bones of 10 racing greyhounds with a fracture of the central tarsal bone and 10 without a fracture were investigated by dual energy x-ray absorptiometry and a servo-hydraulic materials testing machine. In all the greyhounds the bone mineral density of the left fifth metacarpal bone was significantly greater than that of the right (P<0.001), but there was no significant difference between the degree of asymmetry in bone mineral density in the two groups. The ultimate torque and energy-to-failure of the left fifth metacarpal bone of the greyhounds with a fracture of the right central tarsal bone were significantly higher than in the right fifth metacarpal bone and higher than in both the left and right fifth metacarpal bones of the greyhounds with no fracture (P<0.05). The ultimate torque and energy-to-failure were significantly related to bone mineral density (P<0.005), and 22 per cent of the variation in these structural properties could be explained by variations in bone mineral density. Fifth metacarpal remodelling in response to asymmetric cyclic loading is bone-specific, and structural properties are enhanced in the left fifth metacarpal of greyhounds with a fracture of the right central tarsal bone.  相似文献

An 8-year-old American Quarter Horse gelding was evaluated because of an open fracture involving the left radius. The horse had fallen during training and became immediately non-weight-bearing in the left forelimb. On initial evaluation, the horse was unable to bear weight on that limb; radiography revealed a long oblique fracture of the distal metaphysis of the radius with minimal displacement of the fracture fragments. Because of the configuration of the fracture, we recommended surgical intervention with internal fixation. A condylar screw implant and 4.5-mm broad dynamic compression plate were applied to the medial and dorsolateral aspects of the radius, respectively. The horse recovered in a sling and full-limb bandage. Six months after discharge, the horse was reevaluated because of a grade 4/5 lameness in the same limb. Palpation revealed signs of severe pain over the distomedial aspect of the radius. Radiography of the left radius revealed severe osteolysis beneath the distal aspect of the condylar screw implant. Surgical removal of the medial plate was performed. Sixteen months after the initial fracture repair, the horse had returned to light training without signs of lameness. Removal of the dorsal plate may be indicated if this horse is to return to aggressive training or becomes lame in the left forelimb.  相似文献

Long bone fractures in ferrets (Mustela putorius furo) are usually traumatic in etiology, and the femur is commonly affected [1]. A 4-year-old, castrated male ferret was examined for acute, non-weight-bearing lameness of the left pelvic limb after presumably falling from its elevated enclosure. Clinical and radiographic evaluation showed a complete, comminuted fracture of the proximal diaphyseal third of the left femur. Open reduction and internal fixation (ORIF) of the left femoral fracture was performed with cerclage wires and a 1.5 mm locking compression plate with associated locking screws. Anatomic reconstruction was achieved, and postoperative radiographs confirmed appropriate fracture fragment apposition, limb alignment, and implant placement. At 9 weeks postoperatively, the ferret was ambulatory with no evidence of lameness, and complete radiographic union was noted. This is the first published report of the use of a bone plate for femoral fracture stabilization in a ferret. Bone plates, including locking plates, could be considered for long bone fracture stabilization in ferrets as an alternative to other methods.  相似文献

An 18-year-old male, castrated Domestic Shorthaired cat was presented with the complaint of acute severe lameness of the left pelvic limb. There was no history of trauma, apart from a distal physeal left femoral fracture that had been repaired 17 years previously. Radiology revealed a displaced distal metaphyseal femoral fracture with marked areas of bone lysis and periosteal proliferations. A pathological fracture due to a bone neoplasia was suspected. An amputation with coxofemoral disarticulation was performed. Histopathology confirmed the tentative diagnosis of appendicular osteo-sarcoma. No postoperative complications were encountered and the cat made a full recovery. This case shows an unusual presentation of a late-onset fracture-associated feline osteosarcoma.  相似文献

Two kittens aged between four and five months were presented having sustained patellar fractures. In both cases, healing was subsequently documented radiographically; this has not been reported previously in the literature. One kitten had bilateral patellar fractures - the symptomatic right stifle was treated with a pin and tension-band-wire which later failed, at which point partial patellectomy was performed. The fracture of the left patella was minimally displaced and was treated conservatively. A radiograph of the left patella taken eleven months after initial presentation showed complete healing of the fracture. The second case was treated surgically with a circumferential wire; healing of the fracture was demonstrated radiographically at twelve weeks postoperatively. Radiographic images taken five weeks postoperatively had shown some narrowing of the fracture gap. These two cases demonstrate that bony union of patellar fractures can be documented, given a long enough duration of radiographic follow-up; circumferential wire was an effective treatment in a displaced fracture, and conservative treatment resulted in complete healing of a minimally displaced fracture.  相似文献

Two sequential fractures in the left hind leg of a deer and their treatments are described. The first, a tibial fracture was treated using an intramedullary pin with full cerclage wires supported by a plaster cast. This fracture healed uneventfully. A subsequent second fracture involving the distal metatarsus was stabilized by external fixation. This fracture healed with the formation of a periosteal involucrumlike structure which encased the full length of the metatarsal bone. This involucrum was thought to be due to a sub-periosteal hematoma.  相似文献
