Untersuchungen zur Diagnostik der Listerienenzephalitis bei Wiederkäuern unter Anwendung kultureller und immunhistologischer Verfahren

Abstract: Summary Studies on the diagnosis of listeric encephalitis in ruminants using cultural and immunohistological techniques II. Communication: Immunohistological investigations on formalin‐fixed paraffin sections The unlabelled peroxidase‐antiperoxidase (PAP)‐technique was compared with the avidin‐biotin‐peroxidase‐complex (ABC)‐technique in the identification of Listeria antigen in formalin‐fixed paraffin sections of 58 ruminant brains, 44 of which showed histopathological lesions typical for listeric encephaliti… Show more

“…The only occasional occurrence of L. n. in the CSF of affected ruminants may be due to the special pathogenesis of listeric encephalitis with neurotropic ascension of L. m. via cranial nerves and the special histopathological feature with focal lesions of the brain parenchyma usually confined to the brain stem and the medulla oblongata (CHARLTON and GARCIA, 1977). Bacteria are often found intra-and extracellularly within these predominantly neutrophilic parenchymal foci and, occasionally, in malacic areas, but rarely in the mononuclear cell infiltrates in the leptomeninges and in the perivascular spaces of larger vessels (CORDY and OSEBOLD, 1959; MARCO et al, 1988;PETERS et al, 1992). Several studies have documented that the focal lesions in the brain parenchyma only occasionally extend to the ventricular system and meninges (CORDY and OSEBOLD, 1959;TRAUTWEIN and BEHRENS, 1962; CHARLTON and GARCIA, 1977; PETERS, 1991).…”
