Except in imported rams exposed to conditions during transit which had rendered them susceptible to infection, paratyphoid had not until recently been encountered in sheep in Western Australia. During the past few years, however a considerable number of outbreaks have been reported among flock sheep in the agricultural areas. All of these have occurred during the summer months and some of them have been responsible for serious mortality. It is a probable course that the disease has been present in the State for many years and that it has been confused with other conditions such as entero-toxaemia to which it may in some respects bear a superficial resemblance.
