A new virus, named Amapari virus, was isolated from forest rodents and their mites caught in Amapa, Brazil. Through August 1970, more than 350 isolations of MAPARI VIRUS HAVE BEEN MADE, FROM 2041896 RODENTS OF ONLY 2 SPECIES I.E., Oryzomys capito goeldii and Neacomys quianae and from 3 pools of mites from these rodents. In September 1968 a mammal retrapping program was initiated in two different areas of the Serra do Navio region. By studying the wild animal population in its natural habitat, collecting a series of samples from the same individuals, it should be possible to gather information that would reveal not only the presence but also the persistence of the virus in the Oryzomys and Neacomys, its correlation with the state of immunity of them, as well as pertinent data on the breeding habits, home range, seasonal variation and life span of these two species of forest rodents.
