A Study of Outbreaks of Aujeszky’s Disease in Cattle

Abstract

Five selected outbreaks of Aujeszky’s disease in cattle from 1974 and 1975 are described. In an outbreak with anterior pruritus, Aujeszky virus was demonstrated in lung tissue of one animal and in nasal secretions of another, which has further substantiated the view that cattle may get infected with Aujeszky virus by the respiratory route. In two of three outbreaks, which were found to be interrelated, and in a fourth outbreak, all with one affected animal showing posterior pruritus, circumstantial evidence was found of a transmission of the infection by man.

Sammendrag

Der beskrives fem udvalgte udbrud af Aujeszky’s sygdom hos kvæg. I et udbrud, hvor kløe optrådte på forparten, påvistes virus i lungemateriale af eet dyr og i næsesekret af et andet, hvilket har yderligere sandsynliggjort, at lidelsen hos kvæg kan optræde primært som en luftvejsinfektion. I to af tre udbrud med epidemiologisk sammenhæng og i et fjerde udbrud, alle med eet angrebet dyr med kløe på bagparten, fandtes vægtig dokumentation for, at virus var blevet overført med mennesker.
