Vibrio cholerae is a human pathogen that causes mild to severe diarrheal illnesses and has major public health significance. The aim of this study was to investigate the effects of antimicrobial activity of the gold nanoparticles on Vibrio cholera. Gold and Silver nanoparticles are chemically synthesized. Standard strain of Vibrio cholerawas cultured in a nutrient broth. Minimum inhibitory conc...

background: the virulence of a pathogenic vibrio cholerae is dependent on a discrete set of genetic determinants. in this study, we determined the distribution of virulence determinants among the clinical and environmental isolates of v. cholerae. methods: the antibiotic resistance profiles of the isolates were determined using standard disk diffusion assay. pcr assay was performed to analyze t...

A Gram-negative, rod-shaped, motile and halophilic bacterium identified as Vibrio harveyi was isolated from hatchery-reared larval of Iran Shrimp Research Centerfollowing mass mortality . Seven isolates of Vibrio spp.were collected from nauplii of Litopenaeus vannamei and then were evaluated for characteristics including morphology, physiology and biochemistry. The results indicated that the is...

We sequenced a 705-bp fragment of the recA gene from 113 Vibrio cholerae strains and closely related species. One hundred eighty-seven nucleotides were phylogenetically informative, 55 were phylogenetically uninformative, and 463 were invariant. Not unexpectedly, Vibrio parahaemolyticus and Vibrio vulnificus strains formed out-groups; we also identified isolates which resembled V. cholerae bioc...

A quadruplex loop-mediated isothermal amplification (LAMP) method was developed to detect four Vibrio species, including Vibrio ichthyoenteri, Vibrio parahaemolyticus, Vibrio scophthalmi, and Vibrio vulnificus, simultaneously. Four sets of species-specific primers were designed with different restriction sites contained in the inner primers. The quadruplex LAMP method could distinguish four Vib...

Few extraintestinal Vibrio infections have been reported in the African region. We report 3 cases from Mauritius: one case of Vibrio alginolyticus otitis externa; one case of soft tissue infection caused by non-O1 Vibrio cholerae and Vibrio parahaemolyticus; and one fatal case of non-O1 V. cholerae cellulitis and septicaemia.

The Vibrionaceae (Vibrio) are a ubiquitous group of metabolically flexible marine bacteria that play important roles in biogeochemical cycling in the ocean. Despite this versatility, little is known about Vibrio diversity and abundances in upwelling regions. The seasonal dynamics of Vibrio populations was examined by analysis of 16S rRNA genes in Monterey Bay (MB), California from April 2006-Ap...

Background and Objective:Outbreak of food-borne diseases has become more and more important these days and using natural food preservers with high durability is under debate. Vegetative essence is a type of food preserver and many studies have been performed on their antimicrobial effects. The purpose of this study was to investigate antibacterial effects of lavender essence on...

Petroleum hydrocarbon contamination is a major global prevalent issue in the petroleum sector. This research focuses on evaluating biodegradation of three Gram-negative bacilli, isolated from cowpea planted soil, contaminated with kerosene. The Gram negative bacilli strains have been characterized and identified, using MicrobactTM ID24E systems for the identification of Enterobacteriaceae and c...

A new Vibrio strain, V1B, was isolated from the intestinal tract of the scallop Argopecten purpuratus Strain V1B is closely related to the species Vibrio inhibens BFLP-10, which has been characterized as showing antagonistic activity against pathogenic Vibrio sp. We report here the draft genome of the isolated Vibrio sp. strain V1B.
