experimental labyrinthitis in guinea pigs caused by a hantavirus.	hantavirus-induced acute viral infection of the inner ear of guinea pigs is reported. guinea pigs were inoculated directly into the inner ear through the round window, or intraperitoneally with hantavirus (b-1 strain), and the cochlea was examined using an immunohistochemical technique for the localization of viral antigens. virus-specific antigens were detected prominently in the stria vascularis and to a lesser degree in other inner ear structures of the infected guinea pigs. the morphological ...	1991	1901140
identification of hantavirus serotypes by testing of post-infection sera in immunofluorescence and enzyme-linked immunosorbent assays.	serum samples were collected from 27 individuals who had been infected with a member of the genus hantavirus in the netherlands or belgium during the last 15 years. these samples were tested in an immunofluorescence assay (ifa) and two enzyme-linked immunosorbent assay (elisa) systems, using different virus strains that represented each of the four recently proposed serotypes of this genus. the serum samples from 11 individuals who had been infected through contacts with laboratory rats showed t ...	1991	1901907

mechanisms of disease in hantavirus infection: pathophysiology of hemorrhagic fever with renal syndrome.	hemorrhagic fever with renal syndrome (hfrs) is an acute viral disease that occurs over wide areas of europe and asia. hantaviruses are the cause of this syndrome. the hallmark of hfrs is the triad of fever, hemorrhage, and renal failure. in its severe form it is associated with significant mortality. the syndrome evolves through five phases: febrile, hypotensive, oliguric, diuretic, and convalescent. the central physiologic derangement in hfrs is vascular dysfunction, manifested by impaired vas ...	1991	1673261
