광주(光州)·전남지역내(全南地域內) 소의 바이러스성 질병(疾病)에 관한 혈청학적(血淸學的) 연구(硏究)

Sera from 304 Holsteins or Korean native cattle were collected from slaughterhouse in Kwangju area to study the infection of major virus-borne diseases. Serum antibody titers against infectious bovine rhinotracheitis virus(IBRV), bovine viral diarrhea virus(BVDV), parainfluenza type-3 virus(PI-3V), bovine ephemeral fever virus(BEFV), bovine Ibaraki virus(BIV), bovine Akabane virus(BAKV), bovine rotavirus(BRV), bovine coronavirus(BCV) were measured by serum neutralization tests. Results which obtained were as follows. Sera from 280 cattle(92.1%) contained antibodies against BRV which rate was the highest among the 8 viruses, and serum antibodies against BCV, BVDV, BIV, BAKV, BEFV, IBRV and PI-3V were detected from 266(87.5%), 149(49%), 108(35.5%), 94(30.9%), 80(26.3%), 32(10.5%) and 24(7.9%) cattle, respectively. Prevalence of seropositives to BVDV, BIV, BAKV, BEFV were higher among Holsteins than among the Korean native cattle(P
