摘要：

A clinical study concerning the epidemiology of the syndrome endometritis associated with vaginal discharge and reproductive failure is described. In all affected herds the return rates after service were increased above 30% and the number of weaners per sow per year was decreased by at least two. In an experimental infection model the pathogenicity of Escherichia coli on the sow's endometrium was investigated and the influence of the oestrus cycle on the uterine defence mechanism was studied. Ten pubertal, unmated gilts of the Belgian Negative Landrace were infected in the uterus with suspensions of an E. coli strain isolated from the uterus of a discharging sow. The results indicated that it is possible to induce an acute purulent endometritis by inoculation of E. coli. The stage of the oestrus cycle appeared to be an important factor in the development of endometritis. None of the five gilts inoculated at the day of oestrus with 50 ml of a suspension containing 10(7) cfu ml-1 developed clinical symptoms. Three of the five gilts inoculated just after the end of standing heat also developed clinical signs. The difference between both groups was significant.
