indirect immunofluorescence tests in korean hemorrhagic fever and epidemic (endemic) nephropathia: treatment at low ph for removal of 'nonspecific' fluorescence in tissues from immunocompetent hosts.a 'nonspecific' fluorescence probably caused by immunocomplexes appears in the lung tissue of immunocompetent hosts infected with korean hemorrhagic fever (khf) or epidemic nephropathy (en) viruses. indirect immunofluorescence tests with such khf- or en-infected tissue as antigen are unsatisfactory for the detection of low-titer antibody or the reading of titer endpoints. treatment of acetone-fixed lung sections at ph 3.0 followed by washing with 0.01 m phosphate-buffered saline and distilled wa ...19826126464
isolation of hantaan virus, the etiologic agent of korean hemorrhagic fever, from wild urban rats.urban rats captured in seoul and four nearby korean cities were found to have immunofluorescent antibodies reactive with hantaan virus, the etiologic agent of korean hemorrhagic fever (khf). serum antibodies were detected in 13% from 477 rattus norvegicus and 11% of 47 rattus rattus. hantaan viral antigen was found in pulmonary tissues of 42 animals, and hantaan virus was recovered from 23 rats, all but two of which were r. norvegicus. wistar rats were qualitatively much more sensitive than apod ...19826127366
laboratory-acquired infections with hantaan virus, the etiologic agent of korean hemorrhagic fever.clinically apparent infections with hantaan virus, the etiologic agent of korean hemorrhagic fever, occurred in nine persons exposed to the virus at the korea university virus institute (seoul) between 1971 and 1979. all were directly related to trapping of wild rodents or work with naturally or experimentally infected wild and laboratory rodents in a designated animal suite. all infections were acquired during the months of november-april, and none was associated with accidental parenteral inoc ...19826127367
