A survey of Aleutian mink disease virus infection of feral American mink in Nova Scotia

Spleen samples from 14 mink that were trapped in 4 counties of Nova Scotia were tested for the presence of the Aleutian mink disease virus (AMDV) by polymerase chain reaction. Viral DNA was not detected in samples from Kings County (n = 2), but was detected in all the mink sampled from Colchester (n = 2) and Halifax (n = 6) counties, and 3 of 4 mink from Yarmouth County. The high level of AMDV-infected mink in Colchester and Halifax counties may pose a serious threat to the captive mink and wild animal populations. Because treatment of infected free-ranging mink is not an option, AMDV control strategies for the captive mink should be primarily focused on bio-security to protect clean ranches.     

Nonsuppurative meningoencephalomyelitis of unknown etiology in mink

A central nervous system disease of mink occurred in three unrelated fur farms in Oregon in September, 1981. Only kits four to five months old were affected. Clinical signs consisted of posterior ataxia progressing to complete posterior paralysis with loss of motor control and sensation. Complete or partial recovery occurred in approximately 1.5 months in most mink. Microscopic lesions consisted of severe nonsuppurative meningoencephalitis and meningomyelitis with vacuolation of the white matter of the brain and spinal cord. Canine distemper virus infection and other recognized causes were ruled out on the basis of clinical signs, history, lesions, or laboratory findings. Experimental inoculations of mink with brain and spinal cord specimens from affected mink failed to reproduce the disease.     

水貂阿留申病诊断抗原研究概述

近年来,随着水貂养殖行业的不断发展,一些疫病也成为了制约水貂养殖业发展的重要因素。水貂阿留申病作为毛皮动物的三大疫病之一(阿留申病、犬瘟热、病毒性肠炎),是导致母貂产仔率下降、公貂配种能力降低和毛皮质量下降的一种高度接触性传染病。至今为止,还没有商品化的疫苗来控制该病的传播及蔓延。控制水貂阿留申病最好的方法是通过检测淘汰所有抗体为阳性的水貂,进而达到净化貂群的目的。而在抗体检测过程中,诊断抗原的制备和纯化决定着检测方法的敏感性、特异性和准确性。论文对目前阿留申病毒细胞抗原及基因工程抗原研究进展做一综述,为今后该病病原检测工作提供参考。     

Characteristics of inapparent Aleutian disease virus infection in mink.

Inapparent of nonprogressive Aleutian disease virus (ADV) infection is a subclinical but persistent virus infection of mink. Mink with the inapparent type of ADV infection when subjected to stress did not develop the progessive form of the disease. However, when challenged with a large dose of the virus, these mink did develop progressive Aleutian disease indicating that they were not highly resistant to the virus. Sera of mink with either the progressive of the inapparent type of ADV infection did not neutralise the virus. The anti-ADV antibody activity in mink with inapparent type of ADV infection was in the IgG fraction of the serum the same as in mink with progressive Aleutian disease. These data indicate that the resistance of the mink with inapparent infection as compared to mink with progressive Aleutian disease was not due to a difference in the class of immunoglobulin response to the virus. However, mink with progressive Aleutian disease showed a greatly increased immunoglobulin response.     

水貂阿留申病的研究进展

Effect of infectious dose and season on development of hemorrhagic pneumonia in mink caused by Pseudomonas aeruginosa

Hemorrhagic pneumonia is an acute and fatal disease of farmed mink caused by Pseudomonas aeruginosa. The pathogenesis of this disease has not yet been resolved. Mink are the only animals known to be susceptible to acute, contagious, and fatal lung infections caused by P. aeruginosa. The purpose of this study was to investigate the correlation between dose-response and season of infection and to clarify whether Danish mink are carriers of P. aeruginosa on their nasal mucosa during the season for hemorrhagic pneumonia. To elucidate the pathogenesis of the disease, an infectious dose-response trial was carried out on adult mink and mink kits, both in the season for hemorrhagic pneumonia (November) as well as out of season (July). It proved difficult to infect mink via the intra-nasal route. Only 4 out of 60 infected mink developed clinical disease and were euthanized, all of them in November, illustrating that predisposing factors in the mink itself and not infectious dose might be crucial for disease development. We were able to culture P. aeruginosa from the nasal cavity of the clinically healthy experimental mink 8 d after inoculation. This indicated that the mink can carry P. aeruginosa on their nasal mucosa without developing the disease. It was not possible, however, to culture P. aeruginosa from the nasal cavity of clinically healthy mink obtained from farms in November, which indicates that the organism is not a normal part of the nasal mucosal flora of mink.     

Aleutian Disease of Mink: I. Evidence of its Viral Etiology *

A suspension of tissues from field cases of Aleutian disease was used successfully to reproduce the disease in Aleutian mink. Similarly, suspensions of diseased tissues from the experimentally infected mink were used to transmit the agent of Aleutian disease to both Aleutian mink and standard dark mink. Seitz and millipore filtrates prepared from these tissue suspensions were also infective; a suggestion that the etiologic agent is a virus. Genetic factors and hypersensitivity are discussed as possibly contributing to development of the disease.     

Detection of antibody in Aleutian disease of mink: comparison of enzyme-linked immunosorbent assay and counterimmunoelectrophoresis

Experiments were undertaken to investigate the potential of the enzyme-linked immunosorbent assay (ELISA) as a screening test for the diagnosis of the 2 known naturally occurring forms of Aleutian disease of mink. Anti-Aleutian disease virus (ADV) antibody activity was not detectable in the sera of mink with nonprogressive Aleutian disease despite the demonstration of antibody by counterimmunoelectrophoresis (CIEP) in the same sera. Anti-ADV antibody was detectable in 93% of sera from mink at various stages of experimentally induced progressive Aleutian disease. False-negative reactions occurred in sera which demonstrated high anti-ADV antibody titers by CIEP. As a consequence of the high prevalence of false-negative reactions, the ELISA was not considered to be an effective screening test. However, using CIEP as an indicator of ADV infection, the ELISA may be useful in differentiating mink with nonprogressive Aleutian disease from mink with progressive Aleutian disease.
