Mutation research, 175(1), 11-16 (1986-09-01)

Internal exposure of rats to benzidine derived from orally administered benzidine-based dyes after intestinal azo reduction.

R P Bos et al.

Toxicology, 40(2), 207-213 (1986-08-01)

The role of the rat intestinal flora in the azo reduction of some benzidine-based dyes was studied in vitro and in vivo. The formation of benzidine was measured after anaerobic incubation of direct black 38, direct blue 6 and direct

Five new coexisting species of copepod crustaceans of the genus Spaniomolgus (Poecilostomatoida: Rhynchomolgidae), symbionts of the stony coral Stylophorapistillata (Scleractinia).

Mercedes Conradi et al.

ZooKeys, (791), 71-95 (2018-11-06)

Spaniomolgus is a symbiotic genus of copepods of the poecilostomatoid family Rhynchomolgidae and is known to be associated with shallow-water reef-building hermatypic corals. Three species of this genus were previously found only in washings of Acropora and Stylophora in northern
