AbstractAbstract
Members of the genus Vibrio are ubiquitous in aquatic environments and can be found either in a culturable or a viable but nonculturable (VBNC) state. Despite widespread concerns as to how to define the occurrence and dynamics of Vibrio populations by culture-independent approaches, further physiological research and relevant biotechnological developments will require the isolation and cultivation of the microbes from various environments. The present work provides data and perspectives on our understanding of culturable Vibrio community structure and diversity in the Beibu Gulf. Finally, we isolated 1,037 strains of Vibrio from 45 samples and identified 18 different species. Vibrio alginolyticus, V. cyclitrophicus, V. tasmaniensis, V. brasiliensis, and V. splendidus were the dominant species that had regional distribution characteristics. The correlation between the quantitative distribution and community structure of culturable Vibrio and environmental factors varied with the Vibrio species and geographical locations. Among them, salinity, nitrogen, and phosphorus were the main factors affecting the diversity of culturable Vibrio. These results help to fill a knowledge gap on Vibrio diversity and provide data for predicting and controlling pathogenic Vibrio outbreaks in the Beibu Gulf.

AbstractAbstract
EAST1 is produced by a subset of enteroaggregative Escherichia coli strains. This toxin is a 38-amino acid peptide of 4100 Da. It shares 50% homology with the enterotoxic domain of STa and interacts with the same receptor. The mechanism of action of EAST1is proposed to be identical to that of STa eliciting a cGMP increase. EAST1 is associated with diarrheal disease in Man and various animal species including cattle and swine. Nevertheless, as EAST1-positive strains as well as culture supernatants did not provoke unequivocally diarrhea either in animal models or in human volunteers, the role of this toxin in disease is today still debated. This review intent is to examine the role of EAST1 toxin in diarrheal illnesses.
