title: Viability and virulence of Babesia rodhaini eight years after cryogenic preservation with dimethyl sulfoxide.
abstract: Mouse blood infected with Babesia rodhaini and containing an equal volume of 4 M dimethyl sulfoxide was infective after storage at -196 degrees C for 8 years. The Babesia organisms were still able to cause lethal infections after prolonged low temperature storage.
