Results showed that, virus was detected in 2 form 16 sows, and SN titer detected in all 16 sows. The postinfected fetuses on days 14 and 28, virus was detected in almost every fetus but SN titer was not detected. Petechial haemorrhage was found on head and snout of many fetuses. Some mummified fetus was found but no virus was detected. In piglets before colostral feeding group, SN titer was detected only at early and middle pregnancy group (SN titer 0-32). Stillbirth and weak piglets were found in non-immune sow at early and middle gestation. The survival piglets were healthy and maternal antibody titer was detected. However, the virus was detected after birth until 60-120 days old. The most sensitive organ for viral detection were liver, lung and spleen respectively. FACCT was found to be more sensititive that FATST.
