Culturing Helicobacter pylori

As we've expected, my columbia agar plate and defibrinated horse blood arrive today, so now I can get onto work...but wait! How come the expiry date of the two bottles of horse blood are this weird?? "20/05/06" and "??/??/07" ...anyway, I'll check what the hell is wrong with this next week, but I just use one of them for making my CHBHPs, and inoculate the Helicobacter type strain and incubate them as soon as possible. I feel the colonies quite sticky, just like the feeling that I felt when Campys are dying...but I hope this won't be true...
