Characterization of Shigella dysenteriae serotypes 11, 12, and 13.

We conducted serologic and biochemical studies on strains of three provisional Shigella serotypes. Included were 19 strains of serotype 3873-50 from three countries (1 from Mexico, 1 from Netherlands Antilles, and 17 from the United States), 13 strains of serotype 3341-55 from three countries (1 from Canada, 1 from Bulgaria, and 11 from the United States), and 19 strains of serotype 19809-73 fr...

5α-Hy­droxy­eudesm-4(15),11(13)-dien-8β,12-olide

The title compound, C(15)H(20)O(3), a sesquiterpene lactone, was isolated from the aerial parts of Carpesium minus Hemsl. (Compositae). The mol-ecule is composed of three rings, with the two cyclo-hexane rings in chair conformations and the cyclo-pentane ring adopting a twist conformation. The A/B ring junction is trans-fused. The absolute configuration shown has been arbitrarily assigned. In t...
