RESUMEN
We studied a 90 day toxicity in dogs of the compound broxyquinoline + broxaldine--5:1 (enteroquin), applied orally and daily in doses of 0.1 and 0.2/kg t/24 h. We established the toxic manifestations during the period after the 15th day of the treatment: leukopenia, neutropenia and lymphocytosis (by 0.2 kg t/24 h). After the second and fifth day we observed a decrease of appetite, depression of the CNS, paralyses, arrhythmia, progressing loss in weight, proteinorrhea (more pronounced with those receiving 0.2/kg t (24 h); lethal consequence with some part of the animals 25% (ba 0.1/kg t) and 50% (by 0.2 kg t). We found out pathohistologically necrobiotic changes in the medulla oblongata and the kidneys, toxic distrophy of the liver, blood-vessel injuries. The toxic changes observed can be interpreted in connection with the presence of a species specific reaction.

The administration of zink-bacitracin, mainly bacipharmin, at rates of 300 mg per kg with the feed did not produce toxic effects in birds: there were no changes in the general condition and the blood picture, the activity of SGPT and SGOT, the blood level of sugar, and the microstructure of the viscera over a period of 90 days. However, doses of 1000 mg/kg of the preparation given with the feed to chickens led to sporadic cases of slightly expressed karyopycnosis in the renal tubules. Established was a growth-stimulating effect. By the end of the experimental period the relaive weight of the adrenal glands, kidneys, liver, and heart in the treated birds was lower in most of the cases as compared with the weight of the same organs in the control birds.
