[Demonstration of immunoglobulin levels in aborted bovine fetuses in relation to the results of histological, microbiological and viro-serological investigations].
In the pectoral body fluid or in the stomach contents of 63 aborted foetuses, IgG and IgM was demonstrated in 38 foetuses from the fourth month to the end of pregnancy. Out of the 38 foetuses in which immunoglobulins were found to be present, 23 had a positive bacteriological finding. In one case in which Streptococcus agalactiae was isolated, neither IgG nor IgM was found. In the foetuses with a positive bacteriological finding, IgG was found in the body fluid at the average level of 36.75 mg in 14 foetuses, and in the stomach contents at the average level of 17.48 mg per 100 ml in 17 foetuses. IgM was detected in nine foetuses, and in two cases the average level was 7.16 mg and 12.6 mg per 100 ml. In the foetuses with a negative bacteriological finding IgG was found in 14 body fluid samples at the level of 15.06 mg, and in nine foetuses IgG was present in the stomach contents at the level of 17.26 mg per 100 ml; IgM was found in three body fluid samples at the average level of 14.12 mg per 100 ml. Antibodies were demonstrated in the PI3 virus in 28 foetuses and in the BVD-MD virus in 35 foetuses. The serological examination with other antigens was negative. A suspected and positive histological finding was obtained in 30.2% of the foetuses studied. Immunoglobulins were detected in 43.5% of the foetuses with a positive and suspected histological finding. Immunoelectrophoretic examination revealed IgG in 24 foetuses and IgM in 12 foetuses. Transferrin was not demonstrated in nine foetuses at the age from the fifth to the seventh month of pregnancy. Albumin, alpha, and beta-globulins were demonstrated to be present in all foetuses.
