Die Bedeutung von paarigen Serumproben bei akuten Toxoplasmenaborten bei Ziegen.

In a goat herd a series of 49 abortions occurred. Most of the aborted foetuses showed subcutaneous galertic oedema, ascites or hydrothorax, five were mummificated and in 10% of the cases birth of live and death kids together occurred. Fever, dyspnoe and placental retention were the clinical signs of the dams. Four examined dams had no antibodies against pathogenic agents causing abortion (Chlamydia psittaci, Brucella melitensis, Listeria monocytogenes, Coxiella burnetii, Salmonella, Leptospira, Border Disease virus) nor at time of abortion neither 14 days later. Antibodies against Toxoplasma (T.) gondii- except one goat (1:80) - were not detectable at time of abortion but 14 days later (1:540; 1:1620; 1:2000; 1:6000), an acute infection with T. gondii was therefore indicated. At the serological examination 180 days later the same four goats still had high titres (1:60; 1:6000; 1:18000; 1:4000). All of 14 examined goats that had aborted were seropositive, while only three of nine goats that did not abort were seropositive. Kids (n = 5) born together with a dead kid were seronegative. One of four kids born healthy at normal gestation time was seropositive, but seronegative two months later.
