Need help on quantitative bacterial DNA measurements

	I have a request from a person for flow cytometric help in identifying the
number of chromosomes replicating DNA in a bacterium.  He has altered
proteins he/they think are involved in bacterial chromosome replication so
they want to compare the parent strain to the altered strain.  He wants to
be able to establish significantly altered chromsomal replication patters
having 3 or more replication forks.

Any body out there in the US doing this?   How about world wide?

Has anybody out there tried to do this on a jet in air FACS unit?  (You may
laugh now.  If by some miracle somebody did get even close to making this
work--drop me a line will you?)

Does anybody have a microscope based FACS unit that will do this?  Partec
or other variety?

Any useful comment from experience will be greatly appreciated.
