Lecithinase activity of Proteus vulgaris. 1988

District Hygienic Station, Hradec Králové, Czechoslovakia.

Lecithinase production is described as a new biochemical property of P. vulgaris strains grown in a selective agar medium containing brilliant green, crystal violet and lecithin (BCL agar), the authors' own modification of egg-yolk culture medium. By using this BCL agar as a medium inhibiting the swarming growth of P. vulgaris cultures the authors succeeded in identifying 12 lecithinase-positive strains among the P. vulgaris isolates obtained from patients with Crohn's disease. Of 50 P. mirabilis strains tested in parallel none gave the positive test for lecithinase production in this medium.

D003424 Crohn Disease A chronic transmural inflammation that may involve any part of the DIGESTIVE TRACT from MOUTH to ANUS, mostly found in the ILEUM, the CECUM, and the COLON. In Crohn disease, the inflammation, extending through the intestinal wall from the MUCOSA to the serosa, is characteristically asymmetric and segmental. Epithelioid GRANULOMAS may be seen in some patients.
