Identification of a Strain with Algicidal Effects on Red Tide Dinoflagellate in Culture.

The dinoflagellate forms high biomass blooms that discolor the water (red tides), which may pose a serious threat to marine fauna and aquaculture exploitations. In this study, the algicidal effect of a bacterial strain (0YLH) belonging to the genus was identified and evaluated against . The algicidal effects on the dinoflagellate were observed when was exposed to cell-free supernatant (CFS) from stationary-phase cultures of the 0YLH strain.

A plant from the altiplano of Northern Chile , inhibits the pathogen.

Background: In the altiplano of Northern Chile the plant is habitually used as an infusion to relieve the effects of altitude sickness (locally known as "puna"). It is also used to alleviate the bronchitis, whooping cough, asthma, stomachache, tiredness and fever. The extreme conditions under which these plant grow and scientific data that shows the inhibiting potential of the essential oils of plants of the genus represents great potential in the study of their application to control pathogens like .

Oleic acid produced by a marine Vibrio spp. acts as an anti-Vibrio parahaemolyticus agent.

It is known that some strains of Vibrio parahaemolyticus are responsible for gastroenteric diseases caused by the ingestion of marine organisms contaminated with these bacterial strains. Organic products that show inhibitory activity on the growth of the pathogenic V. parahaemolyticus were extracted from a Vibrio native in the north of Chile.

Marine Bacillus spp. associated with the egg capsule of Concholepas concholepas (common name "loco") have an inhibitory activity toward the pathogen Vibrio parahaemolyticus.

The pandemic bacterium Vibrio parahaemolyticus, isolated from seawater, sediment, and marine organisms, is responsible for gastroenteric illnesses in humans and also cause diseases in aquaculture industry in Chile and other countries around the world. In this study, bacterial flora with inhibitory activity against pathogenic V. parahaemolyticus were collected from egg capsules of Concholepas concholepas and evaluated.
