Vibrios associated with Litopenaeus vannamei larvae, postlarvae, broodstock, and hatchery probionts
Article Abstract:
The dominant bacterial flora associated with shrimp larvae showing symptoms of zoea 2 syndrome, mysis mold syndrome and bolitas syndrome in Ecuador was determined using Biolog metabolic fingerprinting and a database of 850 Vibrio type and reference strains. Vibrio alginolyticus is predominantly present in all larval stages and shows high genetic heterogeneity. V. harveyi is associated with diseased postlarvae, juveniles and broodstock. V. parahaemolyticus, Photobacterium damselae and V. mimicus are associated with juvenile and adult stages.

Biodiversity of vibrios
Article Abstract:
The investigation of the gene repertoire at the species level is done by whole-genome sequencing and comparative genomics through the application of microarrays. Comparative genome analyses have revealed a variety of genomic events that are probably important driving forces in the evolution and speciation of vibrios.

Phylogeny and molecular identification of vibrios on the basis of multilocus sequence analysis
Article Abstract:
The usefulness of rpoA, recA, and pyrH gene sequences for the identification of vibrios is analyzed. It is concluded that strains of the same species will have at least 98, 94, and 94% rpoA, recA, and pyrH gene sequence similarity, respectively.
