title: Development of immune-complex glomerulonephritis and amyloidosis in Syrian golden hamsters infected with Opisthorchis viverrini.
abstract: Renal disease associated with Opisthorchis viverrini infection was investigated in Syrian golden hamsters. On the fourth week after infection with 100 viable metacercariae; anti-tegumental membrane antibodies were detected in the sera by immunofluorescence antibody technic and by enzyme-linked immunosorbent assay. Six weeks after infection tegumental and anti-tegumental membrane immune-complex and amyloid fibrils were found in the glomeruli. Amyloid was characterized to be AA protein. Acute proliferative glomerulonephritis associated with the brightest immune-complex deposits developed in week 8 after infection. Intensity of immune-complexes in all glomeruli were reduce gradually thereafter and replaced by amyloid. Progressive obsolescence of the glomeruli, tubular atrophy, interstitial inflammation and fibrosis associated with massive proteinuria and deterioration of renal function appeared in week 10 after infection toward the end of the experiment in week 38 after infection.
