The purpose of the study was to determine the occurrence of Yersinia enterocolitica in tissues of aborted fetuses, placentas, vaginal and rectal swabs of aborting sows from pig farms where reproductive disturbances were found and to determine and analyze the biotype and serotype affinity of the strains isolated. Altogether 97 fetuses aborted in various stages of pregnancy, 25 placentas and swabs from 231 sows were taken. All sows originated from farms where reproductive disorders appeared. In general, 1069 samples were collected. Two enrichment methods were used in this study; fast enrichment techniques in ITC broth, then plating onto CIN agar (ITC/CIN), and cold enrichment in phosphate buffered saline followed by plating onto CIN agar (PBS/CIN). From all samples examined, 96 Y. enterocolitica strains were isolated including 57 (59.4%) from rectal swabs of sows, followed by 6 (6.3%) from vaginal swabs and 2 (2.1%) from placentas. The bacteria were isolated from tissues of 18 out of 97 aborted fetuses. A total of 60 strains were selected for further examination - 29 strains originated from aborting sows and 31 from aborted fetuses. Among strains examined 54 isolates (90%) belonged to the biotype 1A of Y. enterocolitica and to the different serotypes 0:3, 0:5, 0:6, 0:7/13, 0:8 and NT (not typable). Only 6 strains belonged to serotype 0:3, biotype 4 Y. enterocolitica. Our study has revealed the possibility of Y. enterocolitica isolation from internal organs of aborted swine fetuses and sows from farms with reproductive disturbances. The results suggest the connection between fetal death, pregnancy course disorders and Y. enterocolitica infection.

Blood samples were taken from 134 Holstein cows between day 20 to 100 postpartum to determine the concentration of urea, cholesterol, glucose and total lipids and to define their relation to the reproductive performance traits: interval (I), service period (SP) and insemination index (II). Investigations were carried out in monthly intervals from October 1996 to October 1997. Average values of plasma urea, total lipids, cholesterol and glucose for the entire period studied were 5.78 mmol.1⁻¹, 3.61 g.l⁻¹, 3.34 mmol. l⁻¹ and 3.61 mmol. l⁻¹, respectively. High concentration of blood urea was related negatively with the value of the insemination index (rp = -0.51). When the average concentrations of total lipids were low in plasma in the specified time (month) negative correlations were found between total lipids and the length of service period (rp = from -0.23 to -0.54) and value of the insemination index (rp = -0.42). The concentration of plasma total lipids increased in time from post partum. Traits of reproductive performance were affected by the internal environment. Especially negative influences were observed when the concentration of plasma urea as well as total lipids and cholesterol increased or decreased abnormally.
