[The peripartum disease complex of the sow in industrial swine breeds. 1. Peripartum course of bacteriuria of sows with vaginal-vulvar discharge in a modern swine breeding facility].

In an industrial pig production unit ten sows were selected at random. All the sows had puerperal disease in their anamnesis and all of them revealed at the time of selection--during their late pregnancy--Urinary Tract Infection (UT)I and vaginal-vulvar discharge (VD). Mid-stream early morning urine samples were collected during four days ante partum and during four days post partum. The samples were semiquantitatively examined for E. coli and gram positive cocci. Three sows showed ante partum non significant bacteriuria which turned into significant bacteriuria post partum. The majority of the reminding sows revealed a significant bacteriuria during the whole period of examination.
