During a study of the prevalence of Campylobacter jejuni in black-headed gulls (Larus ridibundus) in Sweden, three isolates, strains LMG 24379, LMG 24380T and LMG 24381, were initially identified as Campylobacter lari. Further characterization by both AFLP and whole-cell protein SDS-PAGE analyses revealed that they formed a distinct group in the genus Campylobacter. This unique position was con...

The gorgonian coral Pseudoplexaura porosa contains a lipoxygenase capable of converting exogenous arachidonic acid into (8R)-8-hydroperoxy-5,9,11,14-eicosatetraenoic acid. The (8R)- (or 8-L-) configuration in this product, opposite to that observed in previously reported 8-lipoxygenase products, was determined unambiguously by comparison of oxidative ozonolysis fragments with authentic malic ac...
