RESUMO
Orthopox virus infection is endemic in farms with fur-bearing animals in the Czech Republic (Bohemia and Moravia). This disease is called ectromelia of silver foxes and minks. The infection is congenitally transmitted and manifests itself in reproductive disorders, stillbirth or birth of sick neonates. Adult animals are usually free of clinical symptoms. The infective agent was isolated from recent outbreaks and was identified as a mouse pox virus (Orthopoxvirus muris) by its cultural and immunological characteristics. The significance of this pox virus infection, hitherto not described in Western Europe, is discussed.

The Newcastle disease in Algeria: Study of pathogenic properties of the Newcastle disease viral strains isolated in Algeria. The study of pathogenic characters of 14 strains of Newcastle disease virus isolated from 1972 to 1982 was carried out: The following testS were realized: the mean lethal time for the chicken embryo, the pathogenic power index by intravenous way, the pathogenic power index by intracerebral way, the hemagglutination spectrum and the thermal stability of the hemagglutination. In short we can say that these isolated 14 strains are fast-growing.
