Abstract

Three strains of , representing three human pathogenic genomospecies (B31, ; BR14, ; BR75, ) were grown in BSK-H medium at different temperatures and the spirochaetal cells were counted by dark-field microscopy after 0, 4, 8, 16 and 48 days. Approximate optimum (minimum-maximum) temperatures for the in-vitro growth were found to be 33°C (22-39°C) in strain B31, 35°C (20-40°C) in strain BR75 and 37°C (20-41°C) in strain BR14. Maximum, optimum and minimum growth temperatures seem to be important characteristics of s.l. strains, with relevance for the symptomatology, epidemiology and epizoology of Lyme borreliosis.
