In the eight year period, 1974 to 1981, abortion associated with Salmonella montevideo infection was recorded in 16 flocks in south east Scotland. Two of these flocks experienced infection in each of two years making a total of 18 incidents. Apart from abortion, there was little evidence of ill health in ewes and lambs in affected groups. The number of ewes which aborted in any one flock was very variable. The worst affected had 130 abortions which represented 25 per cent of the animals at risk. On the other hand in 10 of the incidents 6 per cent or less of the pregnant ewes were affected.
