Abstract RNA viruses of filamentous fungi fall into two broad categories, those that contain double-stranded RNA (dsRNA) genomes in rigid particles and those that are more closely related to positive-sense, single-stranded RNA viruses with dsRNA replicative [ncbi.nlm.nih.gov]

Fungal viruses classified as dsRNA viruses fall within two broad categories. The “true” dsRNA viruses have rigid particles containing genomic dsRNA that is not polyadenylated on either strand. [jvi.asm.org]

Certain Orthoreovirus, Orbivirus, Coltivirus, and Rotavirus species infect humans; Phytoreovirus and Fijivirus species infect plants and insects; the cypoviruses (the cytoplasmic polyhidrosis viruses) infect insects, and aquareoviruses infect fish. [ncbi.nlm.nih.gov]

Reoviruses constitute one of the largest virus families in terms of numbers of genera and breadth of host range, which includes plants, arthropods, fish, and mammals ( 21 ; see reference 25 for review). [jvi.asm.org]

The most serious of these diseases is Colorado tick fever, characterized by diphasic fever, headache, muscle pain, anorexia, leukopenia, and weakness; some cases are complicated by encephalitis, hemorrhage, thrombocytopenia, or pericarditis; death is [ncbi.nlm.nih.gov]

Pathogenesis Colorado tick fever coltivirus chronically infects the tick Dermacentor andersoni, which transmits it to humans. [ncbi.nlm.nih.gov]

Reovirus infections have been observed in patients with various conditions such as fever, exanthema, upper and lower respiratory tract illnesses, gastrointestinal illness (including steatorrhea), hepatitis, pneumonitis, keratoconjunctivitis, neonatal [ncbi.nlm.nih.gov]

Erythrocytes, which are enucleated red blood cells, seem to be infected while they are erythroblasts, their nucleated precursor stage. The virus stays in these red blood cells without harming it for up to four months. [microbenotes.com]

All life stages of this tick can transmit Colorado tick fever virus (CTFV) to humans, and Rocky Mountain spotted fever (RMSF) rickettsia (Rickettsia rickettsii) to humans, cats, and dogs. [tickencounter.org]

CTFV is endemic in northwestern North America, where it causes CTF, a human disease initially confused with a mild form of Rocky Mountain spotted fever, which is caused by Rickettsia rickettsii. [doi.org]

These include 1) a complement-fixation test that is relatively insensitive because in 25% of patients complement-fixing antibodies are not detected and in 75% of patients these antibodies appear late after infection; 2) a seroneutralization assay for [doi.org]

Electron microscopic analysis demonstrated that TarTV particle had a non-enveloped bilayer icosahedral structure, and viral inclusion bodies were formed in infected cells. [pubag.nal.usda.gov]

These structures are similar to viral inclusion bodies produced during orbivirus infections ( 15 ). [doi.org]

Patients with neurologic disorders (meningitis, meningoencephalitis, encephalitis) show lymphocyte infiltration of cerebrospinal fluid (CSF), and the virus has been isolated from CSF. [doi.org]
