圈养东北虎FPV感染情况的初步调查与研究 总被引:4,自引:0,他引:4
猫泛白细胞减少症是由猫泛白细胞减少症病毒引起的高度接触性传染病,近些年来该病严重影响着我国圈养大型野生猫科动物的健康.至今,国内外对大型野生猫科动物的FPV流行状况研究甚少.鉴于此,本研究分别于2006年11月、2007年2月和2007年7月随机收集62份、36份、45份虎粪便,利用PCR方法对其带病情况进行检测.结果表明,FPV的阳性率分别为54.8%,25%和0.在以上实验研究的基础上,对该圈养大型野生猫科动物群体中FPV的感染带毒情况和流行特点进行了探讨. 相似文献

There have been few reports on the diversity and prevalence of parasitic fauna of the endangered Siberian tiger, which inhabits the territory of the Russian Far East. The present review attempts to summarize the information about the parasitic fauna of wild Siberian tigers, which includes 15 helminths and 3 protozoan species. The most prevalent parasitic species was found to be Toxocara cati, followed by Toxascaris leonina. Another commonly recorded Platyhelminth species is Paragonimus westermani, which causes a lethal infection of the lung parenchyma in Siberian tigers. However, the information about infections by this fluke in the Siberian tigers is scarce, although P. westermani infections pose a serious health hazard to tiger populations. The nematodes Aelurostrongylus abstrusus and Thominx aerophilus are found in Siberian tigers with an occurrence rate of 2.3% and 19%, respectively. The information on the parasitic infestations of captive populations of Siberian tigers is also presented along with the sources of infection and hazards for the wild tiger populations in their natural environment. 相似文献

通过光镜对东北虎主要几种消化腺的H.E染色石蜡切片进行观察,结果表明,东北虎肝小叶间的结缔组织不发达,小叶的界限不清晰,肝细胞体积较大,核位于细胞一侧,肝细胞多呈索状排列,窦状隙不明显;胰腺外分泌部由腺泡和导管组成,腺泡形状不一,由单层锥状腺上皮细胞组成,胰岛是一些大小不等的细胞团和细胞索,分散于外分泌部之间,胞质染色较外分泌部浅;腮腺为纯浆液腺泡,胞质着色呈嗜酸性,颌下腺是以黏液性细胞为主,含少量的浆液性细胞半月。 相似文献

从营养和管理方式均不同的两组东北虎群中各选5只体型适中的成年雄性东北虎作为研究对象,其中笼养组以纯肉为日粮,散养组以混合饲料为日粮。麻醉后采集静脉血,测定血液中各项生理生化指标,外周血淋巴细胞增殖性反应,以及血清中白细胞介素-2(IL-2)、白细胞介素-6(IL-6)和肿瘤坏死因子(TNF)的含量。结果:散养组外周血淋巴细胞增殖性反应显著高于笼养组(P〈0.05);血清尿素、肌酐、淀粉酶、谷丙转氦酶、谷草转氦酶等指标在两组间差异显著(P〈0.05):全血红细胞计数、白细胞计数、血红蛋白含量、血清蛋白、甘油三酯、总胆固醇等指标组间差异不显著(P〉0.05)。结果显示:营养和管理方式对东北虎某些血液指标产生影响,混合日粮和散养方式更有利于维持东北虎的正常免疫机能和健康。 相似文献

2017年3月19日昆明动物园1头雌性东北虎产下3只幼仔。本项研究通过监控视频,使用瞬时扫描法,记录了雌虎及幼虎在此日后30 d内的行为并进行了整理和分析;观察结果显示,雌虎在哺乳初期的行为以休息和哺乳为主,分别占到了行为总频率的55.13%和19.21%,而幼虎在哺乳初期的行为以休息和吮乳为主,分别占到了71.25%和12.98%。不同时期雌虎出现的休息、哺乳、亲幼虎行为差异显著(P<0.05),移动、进食和其他行为的差异极显著(P<0.01);幼虎表现出的休息、吮乳、拱拔、张望、玩耍和其他行为在6个时期都呈现极显著差异(P<0.01),亲雌虎行为差异显著(P<0.05),而移动行为在不同时期的差异不显著;幼虎在哺乳初期还有新的行为发育出现。 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

野生东北虎保护现状及保护对策探讨 总被引:1,自引:0,他引:1
目前中国野生东北虎数量仅有20只左右,分布在吉林、黑龙江两省的3个不相连的"孤岛状"分布区内.人为干扰导致的栖息地破碎化和猎物种群下降是造成野生东北虎濒危的主要原因.有效的野生东北虎保护计划包括改善虎栖息地质量、控制猎物种群、开展环境教育、解决人虎冲突、完善保护区网络等多方面措施. 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

Two alpha2-adrenoceptor agents, xylazine and medetomidine, in combination with midazolam and ketamine safely and effectively immobilized Siberian tigers (Panthera tigris altaica). The medetomidine protocol used smaller drug volumes, and induction and recovery times were shorter. Although cardiopulmonary abnormalities were noted, none were likely to be life threatening. 相似文献
