| parasite prevalence in free-ranging farm cats, felis silvestris catus. | no animals tested were positive for feline leukemia virus antigen and chlamydia psittaci antibodies, but all were positive for antibodies to feline calicivirus (fcv), feline herpesvirus 1 (fhv1) and rotavirus. they had antibodies to feline parvovirus (96%), feline coronavirus (84% and cowpox virus (2%). antibody to feline immunodeficiency virus (fiv) was found in 53% of animals, which were less likely to be infected with haemobartonella felis, and had higher fhv antibody titres than cats without ... | 1996 | 8620914 |
| feline viruses in wildcats from scotland. | few data are available on the prevalence of feline viruses in european wildcats (felis silvestris). previous surveys have indicated that wildcats may be infected with the common viruses of domestic cats, apart from feline immunodeficiency virus (fiv). in the present study, 50 wildcats trapped throughout scotland (uk) between august 1992 and january 1997 were tested for evidence of viral infection. all were negative for fiv by several serological or virological methods. by contrast, 10% of the ca ... | 1999 | 10073361 |
| viral infections in free-living populations of the european wildcat. | while the importance of viral infections is well studied in domestic cats, only limited information is available on their occurence and prevalence in the european wildcat (felis silvestris silvestris). the aim of this study was to determine the prevalence of antibodies to feline coronavirus (fcov), calicivirus (fcv), herpesvirus (fhv), parvovirus (fpv), immunodeficiency virus (fiv), leukemia virus (felv), and felv antigenemia in 51 european wildcat sera. samples were collected between 1996 and 1 ... | 1999 | 10574526 |
| prevalence and pathogenicity of retroviruses in wildcats in france. | feline leukaemia virus (felv) and feline immunodeficiency virus (fiv) are frequently encountered in domestic cats (felis catus) and in wild felids, but only felv has been previously identified in wildcats (fellis silvestris). thirty-eight wildcats, either captured alive or found dead, were sampled in eastern and central france. nine of them (23.7 per cent) carried the felv p27 antigen, and three (7.9 per cent) had antibodies to fiv. there was a significant relationship between two measures of bo ... | 2000 | 10766116 |
| feline leukemia virus in a captive bobcat. | an 11-mo-old captive-bred male neutered bobcat (felis rufus) presented with lethargy, anorexia, leukopenia, neutropenia, lymphopenia, and nonregenerative anemia. the animal was diagnosed as feline leukemia virus (felv) positive by immunofluorescent antibody and enzyme-linked immunosorbant assay (elisa) testing. it died despite supportive care. pathologic examination revealed multifocal non-suppurative encephalitis, diffuse interstitial pneumonia, multifocal hepatocellular necrosis, non-suppurati ... | 2001 | 11272497 |
| a serologic survey of wild felids from central west saudi arabia. | forty-five wildcats (felis silvestris), 17 sand cats (felis margarita), and 17 feral domestic cats were captured in central west saudi arabia, between may 1998 and april 2000, with the aim to assess their exposure to feline immunodeficiency virus/puma lentivirus (fiv/plv), feline leukaemia virus (felv), feline herpesvirus (fhv-1), feline calicivirus (fcv), feline coronavirus (fcov), and feline panleukopenia virus (fplv). serologic prevalence in wildcats, sand cats, and feral domestic cats were r ... | 2003 | 14567233 |
| copy number polymorphism of endogenous feline leukemia virus-like sequences. | in the cat genome, endogenous feline leukemia virus (enfelv) exists as multiple, nearly full-length proviral sequences. even though no infectious virus is produced from enfelv sequences, transcription and translation have been demonstrated in tissues of healthy cats and in feline cell lines. to test the hypothesis that the enfelv loads play a role in exogenous felv-a infection and pathogenesis, we designed three real-time pcr assays to quantify u3 and env enfelv loads (two within u3 amplifying d ... | 2007 | 17329079 |
| quantification of endogenous and exogenous feline leukemia virus sequences by real-time pcr assays. | endogenous retroviruses are integrated in the genome of most vertebrates. they represent footprints of ancient retroviral infection and are vertically transmitted from parents to their offspring. in the genome of all domestic cats, sequences closely related to exogenous felv known as endogenous feline leukemia virus (enfelv), are present. enfelv are incapable of giving rise to infectious virus particles. however, transcription and translation of enfelv have been demonstrated in tissues of health ... | 2008 | 18295344 |
| when cats' ways of life interact with their viruses: a study in 15 natural populations of owned and unowned cats (felis silvestris catus). | in natural populations, virus circulation is influenced by host behavior and physiological characteristics. cat populations exhibit a great variability in social and spatial structure, the existence of different ways of life within a same population may also result in different epidemiological patterns. to test this hypothesis, we used a logistic regression to analyze the risk factors of feline immunodeficiency virus (fiv), feline herpes virus (fhv), feline calicivirus (fcv), and feline parvovir ... | 2011 | 21705099 |
| [FeLV infection in the cat: clinically relevant aspects]. | The feline leukemia virus (FeLV) is a retrovirus of the domestic cat that was described almost 50 years ago. The FeLV-infection may lead to fatal diseases in domestic and small wild cats. The use of efficacious diagnostics assays and vaccines led to a reduction of the FeLV prevalence; however, FeLV still poses a problem for the cat presented with the infection. This article aims to describe recent developments in diagnostics and findings in the infection pathogenesis that are clinically relevant ... | 2011 | 22045454 |
| disruption of thiamine uptake and growth of cells by feline leukemia virus subgroup a. | feline leukemia virus (felv) is still a major cause of morbidity and mortality in domestic cats and some wild cats despite the availability of relatively effective vaccines against the virus. felv subgroup a (felv-a) is transmitted in natural infections, and felv subgroups b, c, and t can evolve directly from felv-a by mutation and/or recombination with endogenous retroviruses in domestic cats, resulting in a variety of pathogenic outcomes. the cell surface entry receptor for felv-a is a putativ ... | 2012 | 23269813 |
| exposure to selected pathogens in to selected pathogens in geoffroy's cats and domestic carnivores from central argentina. | wild carnivores share a high percentage of parasites and viruses with closely related domestic carnivores. because of increased overlap and potential contact with domestic species, we conducted a retrospective serosurvey for 11 common carnivore pathogens in 40 geoffroy's cats (leopardus geoffroyi) sampled between 2000 and 2008 within or near two protected areas in central argentina (lihué calel national park, la pampa, and campos del tuyú national park, buenos aires), as well as five domestic ca ... | 2012 | 23060491 |
| virological survey in free-ranging wildcats (felis silvestris) and feral domestic cats in portugal. | to determine the presence of viral pathogens in natural areas a survey was conducted on an opportunistic sample of fifty eight wild (felis silvestris silvestris) and feral cats (f. s. catus). the biological materials included serum, lung tissue extract and stool. feline leukemia virus p27 antigen was detected in 13/50 serum/lung tissue extract samples (26%), canine distemper virus antibodies were detected in 2/26 serum/lung tissue extract samples (7.7%), feline coronavirus rna was present in 6/2 ... | 2012 | 22424865 |
| host and viral traits predict zoonotic spillover from mammals. | the majority of human emerging infectious diseases are zoonotic, with viruses that originate in wild mammals of particular concern (for example, hiv, ebola and sars). understanding patterns of viral diversity in wildlife and determinants of successful cross-species transmission, or spillover, are therefore key goals for pandemic surveillance programs. however, few analytical tools exist to identify which host species are likely to harbour the next human virus, or which viruses can cross species ... | 2017 | 28636590 |
| fatal toxoplasmosis in an immunosuppressed domestic cat from brazil caused by toxoplasma gondii clonal type i. | the objective of the study was to report on a fatal case of feline toxoplasmosis with coinfection with the feline leukemia virus (felv). a domestic cat (felis silvestris catus) presented intense dyspnea and died three days later. in the necropsy, the lungs were firm, without collapse and with many white areas; moderate lymphadenomegaly and splenomegaly were also observed. the histopathological examination showed severe necrotic interstitial bronchopneumonia and mild necrotic hepatitis, associate ... | 2017 | 28746448 |
| global mammal parasite database version 2.0. | illuminating the ecological and evolutionary dynamics of parasites is one of the most pressing issues facing modern science, and is critical for basic science, the global economy, and human health. extremely important to this effort are data on the disease-causing organisms of wild animal hosts (including viruses, bacteria, protozoa, helminths, arthropods, and fungi). here we present an updated version of the global mammal parasite database, a database of the parasites of wild ungulates (artioda ... | 2017 | 28273333 |
| tracking the fate of endogenous retrovirus segregation in wild and domestic cats. | endogenous retroviruses (ervs) of domestic cats (erv-dcs) are one of the youngest feline erv groups in domestic cats (felis silvestris catus); some members are replication competent (erv-dc10, erv-dc18, and erv-dc14), produce the antiretroviral soluble factor refrex-1 (erv-dc7 and erv-dc16), or can generate recombinant feline leukemia virus (felv). here, we investigated erv-dc in european wildcats (felis silvestris silvestris) and detected four loci: erv-dc6, erv-dc7, erv-dc14, and erv-dc16. erv ... | 2019 | 31534037 |
| tracking the continuous evolutionary processes of an endogenous retrovirus of the domestic cat: erv-dc. | an endogenous retrovirus (erv) is a remnant of an ancient retroviral infection in the host genome. although most ervs have lost their viral productivity, a few ervs retain their replication capacity. in addition, partially inactivated ervs can present a potential risk to the host via their encoded virulence factors or the generation of novel viruses by viral recombination. ervs can also eventually acquire a biological function, and this ability has been a driving force of host evolution. therefo ... | 2018 | 29642384 |
| a serological survey of common feline pathogens in free-living european wildcats (felis silvestris) in central spain. | twenty-five serum samples of 22 free-living european wildcats (felis silvestris) captured from 1991 to 1993 in central spain were tested for evidence of exposure to seven feline pathogens. all the wildcats but one (95.4%) presented evidence of contact with at least one of the agents (mean = 2.2). contact with feline leukemia virus (felv) was detected in 81% of the wildcats (antibodies, 77%; antigen p27, 15%). antibodies to feline calicivirus (fcv, 80%), feline herpesvirus (fhv, 20%), feline parv ... | 2009 | 32214938 |
