Virus Enteritis of Mink. A Scanning Electron Microscopic Investigation

Vìrus-enteritt hos mink. En skanning elektron-mikroskopisk under-søkelse

Abstract

Advanced lesions in the jejunal mucosa in virus enteritis of mink were studied by scanning electron microscopy. The changes were found to be in good accordance with those observed in the light microscope, and included ballooned degeneration of entero-cytes, epithelial desquamation, the occurrence of fibrinous pseudo-membranes, atrophy or total loss of villi; partially atrophied villi were frequently fused. In some areas there were incipient regenerative processes, including proliferation of ballooned cells which covered the luminal surface of the damaged jejunal wall.

Sammendrag

Langt framskredne forandringer i tynntarmen ved virus-enteritt hos mink ble studert ved skanning elektron-mikroskopi. De ble funnet å være i god overensstemmelse med dem som kan observeres i lysmikroskopet, og inkluderte ballonerende degenerasjon i enterocyttene, deskvamasjon av epitel, og atrofi eller totalt svinn av villi samt forekomst av fibrinøse pseudomembraner; delvis atrofiske villi var ofte sammenvokste. I enkelte områder var det begynnende regenerative forandringer; disse inkluderte proliferasjon av ballonerte celler som delvis dekket den luminale overflaten av tarmen.
