A total of 501 serum samples were selected from blood samples that were submitted to Department of Veterinary Pathology, Kangwon National University from all provinces in Korea from September 2001 to August 2002. Their sera were examined for antibodies to swine influenza virus subtype H1N1 (SlV H1N1) and porcine repro-ductive and respiratory syndrome virus (PRRSV) according to the age of pig, season, and herd size using enzyme-linked immunosorbent assay. The seroprevalence of SIV H1N1, PRRSV, and dual infection were 39.12%, 61.48%, and 25.95%, respectively. The seroprevalence of SIV H1N1 according to herd size was not significant differences (p>0.05). The results showed that the PRRSV infection spread widely in swine herds throughout the country.

대상 데이터
A total of 501 sera from 44 farms were used. These sera were randomly selected (using computer-generated .
The purpose of this study was to investigate the seroprevalence of SIV H1N1 and PRRSV according to the age of pig, season, and herd size from September 2001 to August 2002 in Korea.
데이터처리
2 (SAS Inst, Cary, NC) was used. The comparison between the seroprevalence of SIV H1N1 and PRRSV according to the age of pig, season and herd size was examined using chi-square. The antibody prevalence in dual infection output a frequency.
성능/효과
in spring. The results of antibody prevalence according to herd size were 51.28%, 74.77%,nd 51.18% for < 1, 000, 1, 001-2,000, and 2 2, 001, respectively (Table 5). A peak of seropositivity for PRRSV antibody according to herd size appeared in 1, 001-2, 000.
