Re: why is borrelia growth so slow

[Guest guest]

It's just their life cycle... if you feed a child

more- they don't grow faster.. it's genetically controlled for them,

same as us.

But I've always wonder what their LIFE-SPAN is..

If they're slow growers maybe they have a long life.

Have you ever read anything about that?

Unless you count binary fission (or other division events that may

take place) as ending thier lives - then they can only be (usually)

deathless and ageless. It seems they don't die unless killed.

Nystrom has written some stuff about this or related,

including " Conditional senescence: death of the immortals. " His

intersts run toward the question of aging, proper, but he also knows

alot about bacteria.

I agree Bb is intrinsically programmed for a lower max growth rate

than eg staph, I just wonder why and how.
