Mammalian reoviruses replicate in a broad range of hosts, cells, and tissues. These viruses display strain-dependent variation in tropism for different types of cells in vivo and ex vivo. Early steps in the reovirus life cycle, attachment, entry, and disassembly, have been identified as pivotal points of virus-cell interaction that determine the fate of infection, either productive or abortive....

Specific cellular and host tropism is a characteristic property of many viruses mediated by the interaction of viral attachment proteins with components of the plasma membrane of the cell. We have studied the binding of virus to cells quantitatively by using type 3 reovirus labeled with 125I and GH4C1 pituitary cells in culture. Binding was rapid at both 4 degrees and 15 degrees C and was stabl...

s of papers 59 IBDV as a possible cause of proventriculitis. SPF leghorns were divided into 6 groups. At 4 weeks of age, the birds were challenged with Ark homogenate (Group 6), Ark + 1:10 Anti-Reovirus antibody (Group 5), Ark + undiluted Anti-Reovirus antibody (Group 4), Ark + 1:10 antiIBDV antibody (R63) (Group 3), Ark + undiluted anti-IBDV antibody (R63) (Group 2), and diluent (Group 1). Ant...

The broiler birds after experimental challenge with virulent MAS reovirus developed infection. This infection resulted into poor body weights, uneven growth, poor FCR, poor BPEI and poor PEI. The uninfected birds showed uniform live weights, even growth, better FCR, better BPEI and better PEI. The group with reovirus infection resulted into economic loss while uninfected group resulted into pro...

Persistent reovirus infections of murine L929 cells select cellular mutations that inhibit viral disassembly within the endocytic pathway. Mutant cells support reovirus growth when infection is initiated with infectious subvirion particles (ISVPs), which are intermediates in reovirus disassembly formed following proteolysis of viral outer-capsid proteins. However, mutant cells do not support gr...

UNLABELLED Bloodstream spread is a critical step in the pathogenesis of many viruses. However, mechanisms that promote viremia are not well understood. Reoviruses are neurotropic viruses that disseminate hematogenously to the central nervous system. Junctional adhesion molecule A (JAM-A) is a tight junction protein that serves as a receptor for reovirus. JAM-A is required for establishment of v...

A continuous cell line of rhesus monkey kidney cells, LLC-MK(2), was infected with reovirus type 1 (Lang). The cells were freeze-etched as a method for observing the structural details of the reovirus-induced cytoplasmic inclusion. Information on maturation may be obtained by preparing infected cells for electron microscopy by freeze-etching.

OBJECTIVE Viral interference has been demonstrated in different systems, such as the effect of enterovirus infection on live-attenuated oral polio vaccine. In this study, the effect of reovirus which could exist in the human intestinal tract on poliovirus vaccine strains was investigated and could be an important factor to consider in oral polio vaccination. METHODS Cells were infected with r...

Infection of neonatal mice with some reovirus strains produces a disease similar to infantile biliary atresia, but previous attempts to correlate reovirus infection with this disease have yielded conflicting results. We used isogenic reovirus strains T3SA- and T3SA+, which differ solely in the capacity to bind sialic acid as a coreceptor, to define the role of sialic acid in reovirus encephalit...

Viral attachment to specific host receptors is the first step in viral infection and serves an essential function in the selection of target cells. Mammalian reoviruses are highly useful experimental models for studies of viral pathogenesis and show promise as vectors for oncolytics and vaccines. Reoviruses engage cells by binding to carbohydrates and the immunoglobulin superfamily member, junc...
