狐、貉犬瘟热是由犬瘟热病毒引起的急性、热性、高度接触性传染病,其示病症状为双相热,眼、鼻、消化道等粘膜炎症,以及卡他性肺炎、皮肤湿疹和神经症状为特征的烈性传染病,是危害狐貉最严重的传染病之一,素有毁灭性传染病之称。近几年来,虽然对犬瘟热病防制方面开展了大量的研究工作,在病原学、分子流行病学、免疫及疫苗、诊断等方面取得了一批可喜的成果,对控制该病起到了积极作用,但由于注射疫苗免疫不确切使发病症状不象以往那样典型,因此血清学诊断已无法正确诊断狐貉的犬瘟热病。而综合诊断狐貉犬瘟热病,能快速、简便、准确诊断出犬瘟热病,及早采取防制措施,尽量减少犬瘟热病造成的经济损失。 相似文献

犬瘟热是由犬瘟热病毒引起的高度传染性、接触性传染病。严重危害犬、水貂等犬科动物及其它肉食性毛皮动物,对目前正在蓬勃发展的犬、狐、貂、貉等毛皮动物养殖业构成严重危协。一般情况下,犬瘟热是在犬及所饲养的毛皮动物之间相互传染的。而本人最近诊治了一起由狼传染给犬的犬瘟热病例,具有一定的特殊意义,现报告如下: 我市畜牧局羊场,位于呼伦贝尔草原的额尔古纳河畔,远离村屯。为防止以往每年都有羊被狼咬伤 相似文献

犬瘟热是由犬瘟热病毒引起的犬类急性、热性、高度接触性传染病,病兽以呈双相型发热、鼻炎、严重的消化道障碍、呼吸道炎症等为主要特征。主要通过接触传染,也可通过污染的空气或食物而经呼吸道或消化道感染。幼兽尤其易感,具有较高的发病率和死亡率。我县为貉、狐、貂养殖大县,年存栏近500万只,犬瘟热病时有发生,现将1例貉犬瘟热的诊疗及体会介绍如下。 相似文献

小熊猫等四种动物犬瘟热病毒的分离与鉴定 总被引:8,自引:0,他引:8
对犬,貂,貉,狐,熊,小熊猫,大熊猫,狼,狮,虎,金猫和猞狮共65只动物的病料进行了犬瘟热病毒分离,结果从小熊猫,犬膜梭菌抗毒素对小熊猫,犬,貉和狐四种动物的病料中分离出9株CDV,其中小熊猫CDV具有较强诱导产生中和抗体的能力。该毒株有可能成为疫苗后备株。 相似文献

Raccoon dogs (Nyctereutes procyonoides) are widespread and common in South Korea. In 2011, we obtained serum samples from 102 wild raccoon dogs to survey their exposure to canine distemper virus (CDV). Forty-five of the 102 animals (44.1%) were seropositive. Field cases of canine distemper in wild raccoon dogs from 2010 to 2011 were investigated. Fourteen cases of CDV infection were identified by a commercially available CDV antigen detection kit. These cases were used for virus isolation and molecular analysis. Sequence analysis of hemagglutinin genes indicated that all viruses isolated belonged to the Asia-2 genotype. H protein residues which are related to the receptor and host specificity (residues 530 and 549) were analyzed. A glutamic acid (E) residue is present at 530 in all isolates. At 549, a histidine (H) residue was found in five isolates and tyrosine (Y) residue was found in 6 isolates. Our study demonstrated that CDV infection was widespread in wild raccoon dogs in South Korea. 相似文献

Distemper vaccination of farmed fur animals in Finland 总被引:1,自引:0,他引:1
The most important farmed fur animal species in Finland are the American mink (Mustela vison), blue fox (Alopex lagopus), silver fox (Vulpes vulpes) and raccoon dog (Nyctereutes procyonoides); all are susceptible to canine distemper. The only distemper vaccines currently available are for mink, although they also have been used for fox and raccoon dogs in emergency situations. The efficacy in eliciting neutralizing antibodies and the safety of three mink-distemper vaccines were studied under field conditions with mink and silver fox. Two of the vaccines were also studied with raccoon dogs and blue fox. All three vaccines elicited a satisfactory antibody response in mink, whereas the response varied in the other species. No side effects were observed in any species tested. One of the vaccines was safe and immunogenic in all four species. 相似文献

Concurrent infection of a raccoon by rabies and canine distemper viruses is described. Fluorescent antibody (FA) test demonstrated rabies antigen in the brain of this animal, however, histologically only lesions characteristic of canine distemper infection were seen. We recommend testing tissues for rabies of animals that histologically are positive for canine distemper. 相似文献

The antibody-mediated immune response (AMIR) of dogs to measles and canine distemper viruses has been described. However, there is little information on the cell-mediated immune response (CMIR). The AMIR and the CMIR of dogs to canine distemper and to measles were examined. The CMIR was determined for 6 weeks by measuring the 3H-thymidine uptake by immune lymphocytes in the lymphocyte transformation test. Concurrently, canine distemper and measles virus serum-neutralization antibodies were measured by a microtitration serum-neutralization test. Dogs vaccinated with canine distemper virus had a CMIR and an AMIR to canine distemper. However, measles virus-vaccinated dogs had only a CMIR to canine distemper. A CMIR in the absence of an AMIR indicates that cell-mediated immunity is the most important immune mechanism in protecting measles virus-vaccinated dogs against canine distemper. Development of CMIR and AMIR to canine distemper and measles antigens depended on the age of the dog at the time of vaccination. Adult and juvenile dogs had immune responses to both canine distemper and measles. Neither virus, however, elicited an immune response in neonates. 相似文献
