The effect of gelatin on the growth of Borrelia spirochetes was evaluated in the
second part of this study. The results indicated that gelatin inhibits growth of B. burgdorferi
CA4 and B. bissettii CA389 in BSK H and BSK II media and has no significant effect on the
growth rate of B. corieaceae CA435 in BSK H. This suggests that various genospecies of
Borrelia respond differently to a given environmental factors (e.g. media's viscosity),
emphasizing the difficulty in cultivating these spirochetes.
Norris et al. (1997) have shown that process of culturing Borrelia spirochetes in
BSK H media isolates a limited number of the genospecies circulating in a population. Other
studies have shown that various culture conditions, such as, osmotic strength, dissolved
oxygen and carbon dioxide concentration, and temperature of the growth media can influence
retention and/or expression of the infective phenotype (Elias et al. 1998; Austin 1993).
According to this study gelatin concentration or medium's viscosity may also play an
important role in growth of Borrelia; however, a greater number of isolates should be
evaluated in order to determine the effects of gelatin on the individual genospecies of
Borrelia and the optimal viscosity of the growth media.
The results of this study suggest that BSK H has superior growth supporting
capabilities. For that reason, direct comparisons of research results using spirochetes
maintained in BSK H and BSK II media are inadequate, and re-evaluation of the studies that
used BSK II as the growth media is warranted.

Interesting huh?
