Histological Changes in the Central Nervous System of Swine Inoculated With Some Enteroviruses

Histologische Veränderungen im zentralen Nervensystem der Schweine geimpft mit einige Enteroviren

Histologiska förändringar i centrala nervsystemet hos grisar inokulerade med några enterovirus

Summary

The histopathological changes of the central nervous system in experimental infection of colostrum-deprived piglets with porcine enteroviruses, isolated in Sweden, are described. There was no marked difference in the type of nonpurulent encephalomyelitis caused by a Teschen strain and other strains of porcine enterovirus. A slight affection of the central nervous system may be present without causing clinical symptoms.

Zusammenfassung

Die histopatologischen Veränderungen im zentralen Nervensystem bei experimentell geimpften, ohne Kolostrum aufgezogenen Ferkeln mit in Schweden isolierten Schweineenteroviren wurden beschrieben. Es wurde kein ausgeprägter Unterschied zwischen der nicht-eitrigen Encephalomyelitis verursacht durch einen Teschen-Stam und anderen Schweineenterovirusstämme, beobachtet. Eine leichte Affektion kann in dem zentralen Nervensystem ohne klinische Symptome vorliegen.

Sammanfattning

De histopatologiska förändringarna i centrala nervsystemet vid experimentell infektion med svineenterovirus, isolerade i Sverige har beskrivits. Försöksdjur var smågrisar uppfödda utan kolostrum. Någon påtaglig skillnad i typen av nonpurulent encephalomyelit orsakad av en Teschen-stam och andra enterovirusstammar kunde ej iakttagas. En lätt affektion av centrala nervsystemet kan föreligga utan kliniska symtom.
