| [isolation of babesia microti (frança 1912) from free-living nymphs of ixodes ricinus (linnaeus 1758) (author's transl)]. | 375 unfed nymphs of ixodes ricinus were collected in a natural focus of babesia microti near hannover and were tested for an infection with b. microti using golden hamsters (mesocricetus auratus). 2 strains (hannover ii and hannover iii) were isolated. the incidence of infected nymphs in april 1980 demonstrates the ability of b. microti to hibernate in i. ricinus under natural conditions. | 1981 | 6115558 |
