[Interference of chloramphenicol with some cytoplasmatic enzyme systems].

The activity of alkaline phosphatase was determined in a lot of Wistar white rats which had received during 8 days therapeutical doses of chloramphenicol hemisuccinate, the enzyme being investigated in the circulating granulocytes and the liver. In the neutrophil granulocytes evidence was found of a marked decrease in alkaline phosphatase activity (40% presented a positive activity in the injected animals as against 70% in the controls). In the liver the histochemical test used did not allow for a discrimination between the experimental and control animals. The biochemical test, however, showed depression of alkaline phosphatase activity in the liver of rats receiving chloramphenicol (216.72 muM PO4 mean value as against 267.36 muM PO4).

Toxoplasmosis prevalence parasitologically evaluated in meat animals.

The frequency of Toxoplasma gondii infection in the meat provided by two abattoirs, as well as the pathogenicity of the isolated strains were studied. The parasite carriage was investigated on 299 pools of diaphragmatic muscle (1 pool = 10 animals) from 740 swine, 910 cattle and 1340 sheep: the methods used were bioassays on mice and the precocious identification of the tachyzoites in the peritoneal exudate and after 30 days the cerebral cysts. There were obtained 27 positive results (9.01%), in the examined pools of meat, without significant differences as concerns the frequency in relation to the animal species. Out of these strains two were virulent for mice and rabbits.
