Re: Inoculation of Helicobacter..phase 1

Melissa Jensen observes: >>We are required to do a [Helicobacter] stain on 
every esophagus, stomach,antrum etc. [biopsy specimen]. We use 2 controls a 
day. One for our surgicals..and one for a hospital we service. We run out of 
positive tissue from pts. To buy the controls is expensive.<<

The best solution to this problem would be to watch for the very occasional 
distal gastrectomy specimen from a patient with acute ulcer disease (usually 
with perforation) and untreated Helicobacter pylori infection. I have seen 
one such specimen in the last ten years. Properly prepared, a single specimen 
like this could provide us all with positive controls until kingdom come.
