[Endometritis caused by a foreign body in a cow].

Uterus, uterine tubes, and ovaries of a cow were obtained from the local abattoir. Post-mortem findings indicate a subacute to chronic endometritis, caused by a cigarette-lighter found in utero. The uterine mucosa, covered with mucopurulent secretions, was focally stained black by sulfhemoglobin. Regressed corpora lutea of different sizes and the absence of macroscopically visible tertiary follicles indicate irregularities of the estrous cycle.
