Abstract
A cell culture growth substrate comprising submucosal tissue of a warm-blooded vertebrate and a method for culturing fastidious organisms is described. Submucosal tissue used in accordance with the present invention supports the proliferation of cells when said cells are contacted with submucosal tissue under conditions conducive to cell proliferation.
Claims3
A method for identifying and diagnosing prokaryotic infectious agents, said method comprising the steps of
- obtaining a sample from a source wherein said sample contains prokaryotic infectious agents,
- inoculating a cell growth substrate comprising submucosal tissue of a warm-blooded vertebrate with the sample wherein the submucosal tissue is delaminated from muscle layers and from the luminal portion of tunica mucosa,
- culturing the sample on said substrate under conditions conducive to the proliferation of said prokaryotic infectious agents, and
- identifying and diagnosing the prokaryotic infectious agents.
1 more element
A method for analyzing, in vitro, the growth characteristics of prokaryotic infectious agents, said method comprising the steps of
- inoculating a cell growth substrate comprising submucosal tissue of a warm-blooded vertebrate with the prokaryotic infectious agent wherein the submucosal tissue is delaminated from muscle layers and from the luminal portion of tunica mucosa,
- culturing the prokaryotic infectious agent on said substrate under a selected variable cell growth condition, and
- histologically examining the prokaryotic infectious agent inoculated on said substrate.
