The DNA colony hybridization test with the polynucleotide probe for Vibrio parahaemolyticus toxR gene was performed. All 373 strains of V. parahaemolyticus gave positive results, and the strains belonging to four other Vibrio species including Vibrio alginolyticus gave weakly positive results, suggesting that toxR sequence variation may reflect the phylogenetic relationships of Vibrio species. ...

Background & Aim:During recent decades, infections disease resulting from opportunistic fungi such as Candida albicans and resistance increasing of human pathogenic bacteria to current antibiotics has led to many problems for treating of these diseases. The aims of the present study was to investigate anti-fungi and anti-bacterial effects of Eucalyptus extract...

Biofilm formation results in medical threats or economic losses and is therefore a major concern in a variety of domains. In two-species biofilms of marine bacteria grown under dynamic conditions, Pseudoalteromonas sp. strain 3J6 formed mixed biofilms with Bacillus sp. strain 4J6 but was largely predominant over Paracoccus sp. strain 4M6 and Vibrio sp. strain D01. The supernatant of Pseudoalter...

We coupled multiplex PCR and a DNA microarray to construct an assay suitable for the simultaneous detection of five important marine fish pathogens (Vibrio vulnificus, Listonella anguillarum, Photobacterium damselae subsp. damselae, Aeromonas salmonicida subsp. salmonicida, and Vibrio parahaemolyticus). The array was composed of nine short oligonucleotide probes (25-mer) complementary to seven ...

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...

The study demonstrates whether the Guanchiche of Vinces rivers presents pathogenic bacteria Vibrio type, which can cause many gastrointestinal diseases. fish were obtained directly from sampling sites, and physiological nutritional status was determined through indicators Hepatosomatic Index (IHS), Gonadosomatic (IGS), Condition Factor (CF), microbiological isolation characterization. Values re...

The transmembrane regulatory protein ToxR is required for expression of virulence factors in the human diarrheal pathogen Vibrio cholerae, including cholera toxin (CT) and the toxin coregulated pilus (TCP). ToxR is necessary for transcription of the gene encoding a second regulatory protein, ToxT, which is the direct transcriptional activator of CT and TCP genes. However, ToxR, independent of T...

Five alginolytic, facultatively anaerobic, non-motile bacteria were isolated from the gut of the abalone Haliotis tuberculata. Phylogenetic analyses based on 16S rDNA data indicated that these strains are related to Vibrio wodanis, Vibrio salmonicida, Vibrio logei and Vibrio fischeri (but with <97 % 16S rRNA gene sequence similarity). DNA-DNA hybridization and fluorescence amplified fragment le...
