Abstract
A bottle culture method is described which favours the colony formation of Leptospira icterohaemorrhagiae. The Kitakata strain formed two morphological types of colonies when grown in rubber-stoppered 200ml-square bottle cultures. One was compact and small (C type), while the other diffuse and large (D type). The C and D type sub-strains showed the following differences: The C type leptospirae were longer in body length, but less virulent for suckling mice, young hamsters, guinea pigs, or young rabbits. The C type leptospirae lost 90% of the colony forming units (CFU) after being heated at 45 C for 20 minutes. On the other hand, the D type leptospirae were shorter in body length, virulent in those animals examined and resistant to heating. No serological differences were observed between these two types of sub-strains by agglutination test and in agglutinin absorption test.
