Application of a new formulation of ivermectin [ivomec pour-on] to control external papasiyes of farm animals in Egypt

Testing the efficacy of Ivomec pour-on [1 ml/10 kg b.wt.] against buffalo mites [Psoroptes natalensis], buffalo lice [Hematopinus eurysternus] showed 100%, 100% and 99.98% curicity rate, respectively. It is worthy to mention that this new formulation of Ivomec pour-on has a wide spectrum ectoparasiticidal effect on farm animals under the Egyptian environment

Chromosomal studies in buffalo green monky cells infected with poliovirus type 3

Metaphase chromosomes were prepared from buffalo Green Monkey kidney cells. The diploid chromosomes consisted of 36 meta- or submeta- centric, and 22 were acrocentric. The sex chromosomes were submetacentric in X and a small sub-acrocentric in Y. Chromosome aberrations were studied as a result of poliovirus type 3 infection, and consisted of chromatid gaps and breaks, chromosomal gaps and breaks, deletions, centromeric attenuations, peri-diploidy and polyploidy. The abnormalities were more frequent in infected cells than in normal ones. All chromosomal aberrations except chromatid gaps, deletions, centrometric attenuations and peri-diploidy were significantly higher in infected cells. The results showed that poliovirus type 3 had mutagenic effect on the chromosomes
