In a 500 head dairy sheep flock in Northern Greece, massive abortions (60%) were observed at 110-130 days of gestation. Attempts were made to treat the abortions with oxytetracyclin L.A. 20% but they were not successful. Toxoplasmosis was confirmed by laboratory examination of blood sera of ewes, aborted fetuses, and fetal brain samples. The remaining 200 pregnant sheep were divided in 2 groups of 100 ewes each. Animals of Group 1 were treated with 20 mg/kg b.w. sulfadimidine every other day 4 times, while the animals in Group 2 received 33 mg/kg b.w. sulfadimidine every other day 4 times via i.m. route. Considerable reductions in abortions were observed. The treatments were more effective in Group 2. Lactation started in both groups after treatment and satisfactory milk was produced.

A 3-year-old East Friesian sheep from a sheep flock that suffered from chronic copper poisoning was forwarded to the Clinic of Farm Animals in the Aristotle University. The animal had signs of a hemolytic disease indicative of chronic copper poisoning and also nervous signs. Laboratory examinations were consistent with chronic copper poisoning. This was confirmed after necropsy and liver toxicological analysis. By blood smear examination, metarubricytosis, basophilic stippling, anisocytosis, and polychromasia were found. Also, brain histopathological examination revealed focal areas of gliosis in the cerebral cortex and white matter areas. Satellitosis, neuronal degeneration (chromatolysis) and neuronophagia were also observed. These findings are useful for the clinicians, as nervous signs in flocks suffering from chronic copper poisoning can be attributed to this toxicosis. Also, this study adds in the hematological findings of chronic copper poisoning, as the existing data in the literature are limited.
