Abstract

A total of 1,147 samples of blood serum, collected from porcine foetuses, were examined for the presence of immunoglobulin. The foetuses, from 182 sows, were sampled at abattoirs in Queensland during 1975. For detection and measurement of immunoglobulins, rabbit anti-pig serum and monospecific anti-pig IgG, anti-pig IgM and anti-pig IgA were employed in immunoelectrophoresis, double diffusion and single radial immuno-diffusion assays. Twenty-four foetuses (from 7 litters) had detectable IgG or IgM. None of the samples were positive for IgA. Two of the serums (from siblings) had high antibody titres to porcine parvovirus but in the remainder of the immunoglobulin-positive serums no antibody activity was detected.

摘要

共采集了1147份猪胎儿血清样本，检测其中免疫球蛋白的存在情况。这些胎儿来自182头母猪，于1975年在昆士兰州的屠宰场采集样本。为了检测和测量免疫球蛋白，在免疫电泳、双向扩散和单向放射免疫扩散试验中使用了兔抗猪血清以及单特异性抗猪IgG、抗猪IgM和抗猪IgA。24头胎儿（来自7窝）检测到IgG或IgM。没有样本IgA呈阳性。两份血清（来自同胞）对猪细小病毒具有高抗体滴度，但在其余免疫球蛋白阳性血清中未检测到抗体活性。
