experimental transmission of tahyna virus (california group) to wild rabbits (oryctolagus cuniculus) by mosquitoes.two wild rabbits (oryctolagus cuniculus) were subcutaneously infected with a dose of 2.6 dex. i.c. ld50/0.02 ml of extraneurally passaged tahyna virus strain "236". during the 24-72 hours interval p.i. viremia was demonstrated in both animals ranging from 1.0 to 3.42 dex. i.e. ld50/0.02. mosquitoes aedes vexans, which had fed on them, transmitted the virus to one of three other rabbits. during 24-96 hours interval after terminated feeding of infectious mosquitoes viremia was detected in this ani ...197936333
experimental infection of putorius eversmanni polecats and martes foina martens with tahyna virus.three putorius eversmanni pole-cats and two martes foina martens aged about 9 months were subcutaneously infected with about 260 suckling mouse ld50 of the extraneurally passaged "236" strain of tahyna virus (california group, genus bunyavirus). viraemia with maximal titres of 1.32 (pole-cats) and 1.28 (martens) dex intraperitoneal (i.p.) mouse ld50/0.02 ml was demonstrated from 48 to 96 hr after inoculation (p.i.). by the plaque-reduction neutralization test, seroconversion was demonstrated 15 ...197835949
companion animals as a source of viruses for human beings and food production animals.companion animals comprise a wide variety of species, including dogs, cats, horses, ferrets, guinea pigs, reptiles, birds and ornamental fish, as well as food production animal species, such as domestic pigs, kept as companion animals. despite their prominent place in human society, little is known about the role of companion animals as sources of viruses for people and food production animals. therefore, we reviewed the literature for accounts of infections of companion animals by zoonotic viru ...201627522300
A Recombinant Chimeric La Crosse Virus Expressing the Surface Glycoproteins of Jamestown Canyon Virus Is Immunogenic and Protective against Challenge with either Parental Virus in Mice or Monkeys.La Crosse virus (LACV) and Jamestown Canyon virus (JCV), family Bunyaviridae, are mosquito-borne viruses that are endemic in North America and recognized as etiologic agents of encephalitis in humans. Both viruses belong to the California encephalitis virus serogroup, which causes 70 to 100 cases of encephalitis a year. As a first step in creating live attenuated viral vaccine candidates for this serogroup, we have generated a recombinant LACV expressing the attachment/fusion glycoproteins of JC ...201222013033

tahyna virus genetics, infectivity, and immunogenicity in mice and monkeys.tahyna virus (tahv) is a human pathogen of the california encephalitis virus (cev) serogroup (bunyaviridae) endemic to europe, asia, and africa. tahv maintains an enzootic life cycle with several species of mosquito vectors and hares, rabbits, hedgehogs, and rodents serving as small mammal amplifying hosts. human tahv infection occurs in summer and early fall with symptoms of fever, headache, malaise, conjunctivitis, pharyngitis, and nausea. tahv disease can progress to cns involvement, although ...201121435229
serological surveillance for tahyna virus (california encephalitis orthobunyavirus, peribunyaviridae) neutralizing antibodies in wild ungulates in austria, hungary and romania.a serosurvey for tahyna virus (tahv), a mosquito-borne california encephalitis orthobunyavirus (peribunyaviridae) endemic to europe, was performed to estimate the activity of tahv on a broad geographic scale. sera from wild boar (sus scrofa), roe deer (capreolus capreolus) and red deer (cervus elaphus) were collected from austria, hungary and romania. samples were tested for neutralizing antibodies against tahv using a virus microneutralization assay. the results demonstrate that tahv transmissi ...201829516663
differences in neuropathogenesis of encephalitic california serogroup viruses.the california serogroup of orthobunyaviruses comprises a group of mosquitoborne viruses, including la crosse (lacv), snowshoe hare (sshv), tahyna (tahv), jamestown canyon (jcv), and inkoo (inkv) viruses, that cause neurologic disease in humans of differing ages with varying incidences. to determine how the pathogenesis of these viruses differs, we compared their ability to induce disease in mice and replicate and induce cell death in vitro. in mice, lacv, tahv, and sshv induced neurologic disea ...201930882310
