title: [Sleeper syndrome in beef cattle; meningoencephalitis caused by Haemophilus somnus].
abstract: Central nervous system disturbances, among which somnolence was a particularly marked feature, were observed in a herd of four-month-old beef cattle. Laboratory studies showed that the clinical picture was due to meningo-encephalitis, from which Haemophilus somnus was isolated. Other animals of this herd showed a serological response with regard to the micro-organism. The importance of further studies on the incidence of this infection in the Netherlands is stressed.
