RESUMO

Ixodes dammini ticks from two northwestern Illinois sites were found to be infected with Borrelia burgdorferi at rates of 19 and 32%. B. burgdorferi isolates, one from each site, had protein and antigenic patterns similar to those of the B-31 strain. An indirect immunofluorescence method proved to be more sensitive than dark-field microscopy in detection of these spirochetes. A modified BSK medium containing rifampin was found to be more efficient for spirochete isolation than unsupplemented BSK medium.
