CV-1 monkey kidney cell line -- a highly susceptible substrate for diagnosis and study of arboviruses

The CV-1 cell line, derived from Cercopithecus aethiops monkey kidneys, acquired in the course of serial passaging an epitheloid morphology and heteroploid karyotype. As compared with Vero and GMK cell lines, the CV-1 line proved to be more susceptible to a broad spectrum of arboviruses belonging to the families Togaviridae and Bunyaviridae. Most of them reached high titres and were markedly cytopathic in CV-1 cells so that all tests based on the cytopathic effect could be carried out. The CV-1 cell line can thus be recommended as an extra-ordinarily suitable substrate for the diagnosis and study of arboviruses.
