BOVINE EHRLICHIOSIS IN CENTRAL SWITZERLAND

Due the examination of six Brown Swiss cows the <<Schinberg-fever>> cl inical picture known for years in central Switzerland could be identif ied as bovine ehrlichiosis. Clinical signs were observed 23 to 116 day s after the animals were turned out on pasture. Main symptoms were fev er and reduced milk yield. All animals were infested with ticks and sh owed a severe leucopenia. In buffy coat preparations Ehrlichia phagocy tophila could be identified in neutrophils and eosinophils, rarely in monocytes. All six cows could be successfully treated with oxytetracyc line.
