I've been working with Campy for years. They are really easy to handle, at
least the way we do things.
There are companies that supply bottled gases of one sort or another for
industrial uses--e.g., places where you normally get nitrogen or CO2
It is possible to order cylinders with the campy gas mix --a bit expensive
($250/per bottle), but well worth it. A tank will last for 6 months or
We place our plates in Zip Lock style plastic bags. I find that freezer
bags work best. We have used Glad bags, Hefty Bags, Zip Lock, etc. The
brand doesn't seem to make as much difference as whether or not the bag is a
The bags are then "gased" with the campy gas. Usually, I fill and empty the
bag a couple of times to flush the air out.
This works wonderfully.
I typically grow my organism on Campy-Cefex plates as described by Stern et
al. These are Brucella Agar plates that have been spiked with Cefaperizone,
cycloheximide; and I like to add rifampicin.
Lysed horse blood is added to the plates too.
I don't want to post my name and phone number here, nor my real email
address--you can figure out who I am by doing a quick search-- Avian
Diseases 47:753-758--2003. I'd welcome a phone call from anyone who wants
to talk about campy.
