| antigenic and genetic diversities of babesia ovata in persistently infected cattle. | exploring the antigenic and genetic diversities of babesia ovata, we obtained several field isolates from grazing cattle in the okushiri island, japan. parasite isolation was greatly facilitated by using bovine red blood cell-substituted scid mice (bo-rbc-scid mice), into which the blood samples of the cattle were inoculated. isolates from different individuals within a herd of cattle were compared in immunoblot analysis with an anti-b. ovata serum and also in southern blot analysis with a probe ... | 1998 | 9879533 |
