Tissue samples from 2 juvenile ferrets (Mustela putorius furo) from a colony that was undergoing an outbreak of respiratory disease were submitted to the Iowa State University Veterinary Diagnostic Laboratory. Microscopic examination of lung samples revealed bronchointerstitial pneumonia with necrotizing bronchiolitis. Influenza A virus was detected in sections of formalin-fixed lung by immunohistochemistry and reverse transcription polymerase chain reaction assay. A field investigation of the premises and analysis of additional samples led to the confirmation and characterization of an influenza virus with high homology to contemporary reassortant H1N1 swine influenza viruses. Although ferrets have been used extensively to research the virulence and transmissibility of avian, human, and swine influenza virus strains, no published information exists on naturally occurring outbreaks of swine influenza in ferrets.

    ABSTRACT: Infl uenza A pandemic (H1N1) 2009 virus continues to rapidly spread worldwide. In 2009, pandemic (H1N1) 2009 infection in a domestic cat from Iowa was diagnosed by a novel PCR assay that distinguishes between Eurasian and North American pandemic (H1N1) 2009 virus matrix genes. Human-to-cat transmission is presumed. Influenza viruses are typically host specific; aquatic birds are considered the primary reservoir. However, interspecies transmission does occur (1–9) and occasionally leads to novel host-adapted strains. Interspecies transmission of influenza virus has been a public health concern because of the possibility that, through reassortment, a novel strain with zoonotic potential could emerge. The recent infection of dogs with equine influenza virus (H3N8) (2) and of swine with human influenza virus (H1N2) (4) are particularly intriguing because the former resulted in influenza becoming endemic in dogs and the latter resulted in a documented reassortment event between human and swine influenza viruses. Such concern has escalated with the recent emergence of the novel quadruple-reassorted influenza virus (H1N1) [pandemic (H1N1) 2009] in humans (10). Although infection and transmission of the virus have occurred primarily among humans, occasional transmission from infected persons to susceptible animals (e.g., swine, turkeys, ferrets) has been documented (11). The likelihood of pandemic (H1N1) 2009 infection of domestic pets has been considered less likely ( qa.htm,, H1N1); however, we report a confirmed case of pandemic

    ABSTRACT: A novel swine-origin H1N1 influenza A virus has been identified as the cause of the 2009 influenza pandemic in humans. Since then, infections with the pandemic (H1N1) 2009 influenza virus have been documented in a number of animal species. The first known cases of lethal respiratory disease associated with pandemic (H1N1) 2009 influenza virus infection in house pets occurred in domestic cats in Oregon. A 10-year-old neutered domestic shorthair and an 8-year-old spayed domestic shorthair died shortly after developing severe respiratory disease. Grossly, lung lobes of both cats were diffusely firm and incompletely collapsed. Histologically, moderate to severe necrotizing to pyonecrotizing bronchointerstitial pneumonia was accompanied by serofibrinous exudation and hyaline membranes in the alveolar spaces. Influenza A virus was isolated from nasal secretions of the male cat and from lung homogenate of the female cat. Both isolates were confirmed as pandemic (H1N1) 2009 influenza virus by real-time reverse transcriptase polymerase chain reaction. With immunohistochemistry, influenza A viral antigen was demonstrated in bronchiolar epithelial cells, pneumocytes, and alveolar macrophages in pneumonic areas. The most likely sources of infection were people in the household with influenza-like illness or confirmed pandemic (H1N1) 2009 influenza. The 2 cases reported here provide, to the best of the authors' knowledge, the first description of the pathology and viral antigen distribution of lethal respiratory disease in domestic cats after natural pandemic (H1N1) 2009 influenza virus infection, probably transmitted from humans.

    ABSTRACT: There are a number of newly described and emerging disease syndromes affecting the domestic ferret, and the purpose of this article is to make veterinarians aware of these diseases. A recently described systemic coronavirus infection appears to be a variant of the ferret enteric coronavirus and is currently termed “ferret infectious peritonitis.” Disseminated immunopathologic myositis, aplastic anemia/bone marrow aplasia, acute hemorrhagic syndrome, and oral ulcerations are also described, although the exact etiologies for these diseases have yet to be determined. There appears to be at least 2 important amino acid metabolism deficiencies in ferrets: hindlimb weakness in older ferrets (L-carnitine) and cysteine urolithiasis. Ferrets have recently been found to be susceptible to H1N1 influenza, so knowledge regarding this zoonotic disease is essential for veterinarians working with these animals. A novel Mycoplasma spp. has also recently been identified in ferrets with chronic respiratory problems that originated from one breeding colony. Because these diseases are still being investigated, practitioners who treat a ferret patient exhibiting clinical signs consistent with any of the conditions mentioned are encouraged to contact people who are knowledgeable of that particular illness.
