REVIEW
Laura L Wade
Companion ferrets need to be vaccinated against 2 viral diseases that cause neurologic illness: canine distemper and rabies. Although not common in ferrets, both viruses are fatal in ferrets and rabies virus is also fatal in humans. In this article, we provide a basic review of the 2 diseases, highlighting key neurologic concerns. We also review and update current vaccine concerns from a practitioner's perspective, including available vaccines, vaccine schedule recommendations, vaccine reactions, and risk assessment...

The highly contagious canine distemper viruses (CDVs) are still a major threat to a wide range of natural susceptible hosts. The nucleocapsid (N) protein plays various roles in the virus-induced immune response. But precise mapping of epitopes and antigenic variations in N protein of CDV are still scant. In this study, two monoclonal antibodies (MAbs), designated as F8N and G3N, against the N protein of CDV were generated and characterized. The epitopes recognized by the two MAbs were mapped by truncated N protein fragments expressed in E...

Behavioral alterations in dogs are not easy to understand and cure. The situation is more difficult when an encephalitis due to Canine Distemper Virus (CDV) and a concomitant olfactory neuroblastoma are present. This case report deals with the story of a 5-year-old Swiss shepherd dog with behavioral changes, seizures, epistaxis and ataxia. Following clinical and laboratory exams, a suspected diagnosis of CDV infection was hypothesized, and a therapy based on Ω-interferon was administered. Every supporting therapy failed and the worsening of the clinical conditions led to the euthanasia of the patient...

The critically endangered population of Far Eastern leopards (Panthera pardus orientalis) may number as few as 60 individuals and is at risk from stochastic processes such as infectious disease. During May 2015, a case of canine distemper virus (CDV) was diagnosed in a wild leopard exhibiting severe neurologic disease in the Russian territory of Primorskii Krai. Amplified sequences of the CDV hemagglutinin gene and phosphoprotein gene aligned within the Arctic-like clade of CDV, which includes viruses from elsewhere in Russia, China, Europe, and North America...

Type I interferons (IFNs) such as IFN-α, IFN-β, IFN-ε, IFN-κ, and IFN-ω represent cytokines, which are deeply involved in the regulation and activation of innate and adaptive immune responses. They possess strong antiviral, antiproliferative, and immunomodulatory activities allowing their use in the therapy of different viral diseases, neoplasms, and immune-mediated disorders, respectively. Initially, treatment strategies were based on nonspecific inducers of type I IFNs, which were soon replaced by different recombinant proteins...

Canine distemper virus (CDV), is a pantropic agent of morbillivirus that causes fetal disease in dogs. Base on a broad host rang of CDV, the continued vaccines inoculation is unavoidable to pose gene recombination risk in vaccine virus and wild virus. The current study presents the construction of novel vectors, using equine herpesvirus type 1 (EHV-1) expressing the canine distemper virus (CDV). The recent field strain hemagglutinin protein and nucleoprotein were used for the construction of the viral vector vaccines...

In this study, four canine distemper virus (CDV) strains were isolated from captive Siberian tigers (Panthera tigris altaica) and red pandas (Ailurus fulgens) during two separate CDV outbreaks in a zoo in Guangdong province, China. Sequence alignment and phylogenetic analyses based on the full-length hemagglutinin (H) and fusion (F) genes showed that they were closely identical to genotype Asia-1. Prior to confirmation of CDV in Siberian tigers, to control spread of the disease, a live attenuated combination CDV vaccine was used among almost all carnivore animals except for red pandas in which another recombinant combination CDV vaccine was used...

Canine distemper virus (CDV) is a major infectious disease of dogs. Although vaccines were successful to control CDV spread in canine population, the disease is still common and may pose a threat to unvaccinated dogs. In the attempt to develop specific anti-viral therapeutic tools, the efficacy of several molecules against CDV has been investigated in vitro. In this study the antiviral efficacy in vitro against CDV of ribavirin and boceprevir alone or in combination was evaluated. CDV growth in VERO cells was inhibited by ribavirin, by boceprevir and by a combination of the two molecules at non-cytotoxic concentrations, as evaluated by end-point viral titration in cell monolayers and by quantification of viral RNA using quantitative RT-PCR...

Interferon has a broad-spectrum of antiviral effects and represents an ideal choice for the development of antiviral drugs. Nonetheless, information about alpha interferon (IFN-α) is vacant in Amur tiger (Panthera tigris altaica), an endangered species and indigenous to northeast Asia. Herein, 11 PtIFN-αs genes, which encoded proteins of 164-165 amino acids, were amplified. Afterwards, expression and purification were conducted in Escherichia coli. In physicochemical analysis, PtIFN-αs were shown to be highly sensitive to trypsin and remained stable despite changes in pH and temperature...

The pathological and molecular findings associated with Talaromyces marneffei-induced pneumonia with concomitant infection by canine distemper virus (CDV) are described in a dog. The principal pathological alteration occurred in the lungs. Histopathology confirmed multifocal granulomatous pneumonia associated with numerous intralesional and intracellular septate fission cells consistent with T. marneffei. A molecular assay designed to amplify a partial fragment of the 18S rRNA gene of T. marneffei provided positive results from two fungal cultures derived from the lung...

Raccoons (Procyon lotor) are found worldwide. They are frequently seen in crowded inner cities as well as in forests or wooded areas, often living in proximity to humans and their pets. We examined sera from 100 wild raccoons in Japan for antibodies to six canine viruses with veterinary significance to assess their potential as reservoirs. We also aimed to understand the distribution of potentially infected wildlife. We found that 7% of samples were seropositive for canine distemper virus (CDV), 10% for canine parvovirus type 2, 2% for canine adenovirus type 1, 6% for canine adenovirus type 2, and 7% for canine coronavirus...

Canine distemper (CD) is a highly contagious disease caused by the canine distemper virus (CDV), and mortality can be as high as 100%. However, there is no specific treatment for CD. In this study, the antiviral activity of the caffeic acid against CDV was evaluated in vitro. The results showed that the IC50 of the caffeic acid against CDV at 1 and 2 h post infection (PI) is 23.3 and 32.3 μg/mL, respectively. Consistently, at 1 and 2 h PI, the caffeic acid exhibited a reduced (23.3-57.0% and 37.2-38.1%) viral inhibitory effect in vero cells...

BACKGROUND: Canine distemper (CD) is a widespread infectious disease that can severely impact a variety of species in the order Carnivora, as well as non-carnivore species such as non-human primates. Despite large-scale vaccination campaigns, several fatal outbreaks have been reported in wild and domestic carnivore populations. This, in association with expansion of the disease host range and the development of vaccine-escape strains, has contributed to an increased demand for therapeutic strategies synergizing with vaccine programs for effectively controlling canine distemper...

Animal host-microbe interactions are a relevant concern for wildlife conservation, particularly regarding generalist pathogens, where domestic host species can play a role in the transmission of infectious agents, such as viruses, to wild animals. Knowledge on viral circulation in wild host species is still scarce and can be improved by the recent advent of modern molecular approaches. We aimed to characterize the fecal virome and identify viruses of potential conservation relevance of diarrheic free-ranging wolves and sympatric domestic dogs from Central Portugal, where a small and threatened wolf population persists in a highly anthropogenically modified landscape...
