Vibrio alginolyticus is a Gram-negative halophilic bacterium with worldwide distribution. In this work, we report the draft genome sequence of a V. alginolyticus strain (E0666) isolated from Epinephelus coioides ascites in the Shantou city of Guangdong Province, China.

Type III secretion systems (T3SSs) contribute to microbial pathogenesis of Vibrio species, but the regulatory mechanisms are complex. We determined if the classic ExsACDE protein-protein regulatory model from Pseudomonas aeruginosa applies to Vibrio alginolyticus. Deletion mutants in V. alginolyticus demonstrated that, as expected, the T3SS is positively regulated by ExsA and ExsC and negativel...

A study was performed to investigate the genomic variations in the shrimp farm isolates of Vibrio alginolyticus and V. harveyi when the isolates were subjected to environmental stress. Samples of shrimps, water and sediment were collected from Southern Indian coastal shrimp farms. Vibrio isolates were biochemically identified and confirmed using 16S rDNA and gyrB gene specific PCR. The bacteria...

The aim of this research was to study the occurrence of Vibrio spp., Aeromonas hydrophila, Escherichia coli and Campylobacter spp. in crayfish from Azerbaijan Province using culture method and PCR assay. A total of 55 isolates were collected from 97 studied samples. Vibrio spp., A. hydrophila, E. coli and Campylobacter spp. were detected in 26 samples (26.8%), 12 samples (12.3%), 15 samples (15...

vibrio species are the major seafood-borne bacteria that are frequently associated with the consumption of contaminated sea food. a total of 113 samples including 58 fish and 55 shrimps were studied for the possible contamination with vibrio species. a biochemical protocol was applied for the identification of the vibrio isolates and polymerase chain reaction (pcr) was carried out to confirm th...

Present study summarizes the control of Vibrio alginolyticus infection in hatchery reared Clownfish, Amphiprion sebae with the extract of the mangrove plant, Avicennia marina. Fishes with visible symptoms of hemorrhagic spots were chosen and the genomic DNA of the causative bacterium was isolated and sequenced based on 16S rDNA gene. The in vitro assay revealed that a fraction of A. marina leaf...

In this study, a total of 54 Vibrio alginolyticus strains were analyzed. The isolates were recovered from different compartments of the Ruditapes decussatus hatchery in the National Institute of Marine Sciences and Technologies, Monastir, Tunisia. All isolates were biochemically identified (API 20E and API ZYM strips), characterized by amplification of the Hsp-40 gene polymerase chain reaction ...

The aim of the study was to identify vibrio disease in Eucheuma cottonii samples which had characteristics ice-ice disease, namely thallus whitish and broken. research conducted at two locations Lombok, Ekas Bay waters Buwun Mas Village. were identified as bacteria Sekotong Marine Aquaculture Center using biochemical methods. results showed that associated with observed seaweeds. types cause ar...

Bacterial flagella are extracellular filaments that drive swimming in bacteria. During motor assembly, flagellins are transported unfolded through the central channel in the flagellum to the growing tip. Here, we applied in vivo fluorescent imaging to monitor in real time the Vibrio alginolyticus polar flagella growth. The flagellar growth rate is found to be highly length-dependent. Initially, the fla...

A potentiometric aptasensing assay that couples the DNA nanostructure-modified magnetic beads with a solid-contact polycation-sensitive membrane electrode for the detection of Vibrio alginolyticus is herein described. The DNA nanostructure-modified magnetic beads are used for amplification of the potential response and elimination of the interfering effect from a complex sample matrix. The soli...
