Immunoglobulins were isolated and purified from the colostrum and serum of progressive pneumonia virus infected sheep and also from non-infected control sheep. Four classes of immunoglobulins were isolated from sheep colostrum (IgG1, IgG2, IgA and Ig10s). Three classes of immunoglobulins were isolated from sheep serum (IgG1, IgG2 and IgM). Low levels of virus neutralizing activity were demonstrated only in the whole serum and purified serum IgG1 preparations. No complement fixing activity was detected in any of the antibody preparations from colostrum.
从感染进行性肺炎病毒的绵羊的初乳和血清以及未感染的对照绵羊中分离并纯化免疫球蛋白。从绵羊初乳中分离出四类免疫球蛋白（IgG1、IgG2、IgA和Ig10s）。从绵羊血清中分离出三类免疫球蛋白（IgG1、IgG2和IgM）。仅在全血清和纯化的血清IgG1制剂中显示出低水平的病毒中和活性。在初乳中的任何抗体制剂中均未检测到补体结合活性。
