The horizontal transfer of genes by mobile genetic elements such as plasmids and phages can accelerate genome diversification of Vibrio spp., affecting their physiology, pathogenicity, and ecological character. In this study, sequence analysis of three plasmids from Vibrio spp. previously isolated from salt marsh sediment revealed the remarkable diversity of these elements. Plasmids p0908 (81.4...
We report a case of a patient who developed cystitis caused by non-serogroup O1 Vibrio cholerae after swimming in the Chesapeake Bay. Treatment was empirical, with complete symptomatic resolution. Genitourinary tract infections by Vibrio spp. are uncommon but should be considered when cystitis occurs after saltwater exposure in appropriate geographic regions.
We describe a simple colony overlay procedure for peptidases (COPP) for the rapid fluorogenic detection and quantification of Vibrionaceae from seawater, shellfish, sewage, and clinical samples. The assay detects phosphoglucose isomerase with a lysyl aminopeptidase activity that is produced by Vibrionaceae family members. Overnight cultures are overlaid for 10 min with membranes containing a sy...
AIMS A numerical taxonomic study of halophilic Vibrio isolated from healthy and brown ring disease (BRD) affected manila clams (Ruditapes philippinarum), harvested from the Atlantic coast of south-western Spain, was performed. METHODS AND RESULTS Characterization of 123 presumptive Vibrio spp. was carried out using 94 phenotypic tests. Simple matching and Jaccard similarity coefficients were ...
Bacteria were readily isolated from the hemolymph of a majority (88%) of the blue crabs collected from Galveston Bay, Texas. The hemolymph of most crabs contained moderate (greater than 10(3) bacteria/ml) to heavy (greater than (10(5) bacteria/ml) infections. Large variances were observed in the bacterial number associated with individual crabs, but no significant difference was observed betwee...
Microbial infections outbreak in aquatics are important challenges, and farmers have major difficulties dealing with microbes especially regarding their antibiotic resistance. The purpose of this study was comparative evaluating of antimicrobial activity of silver nanoparticles (Ag NPs) against one gram-positive bacteria (Bacillus spp) and a gram-negative (Vibrio harveyi). In this experimental ...
We identified 131 strains of Vibrio fluvialis among 400 nonagglutinating Vibrio spp. isolated from patients with diarrhea in Kolkata, India. For 43 patients, V. fluvialis was the sole pathogen identified. Most strains harbored genes encoding hemolysin and metalloprotease; this finding may contribute to understanding of the pathogenicity of V. fluvialis.
The Vibrio spp. are the most common and harmful shrimp pathogenic bacteria causing serious diseases of larval and postlarval stages in the hatchery. The Vibrio inhibitory activity of green algae Tetraselmis suecica has been reported in vitro (Austin and Day 1990).In these experiments, the inhibitory activity was assessed in vivo in a commercial shrimp hatchery of the white prawn Fenneropenaeus ...

Current investigation characterized export quality shrimp samples in terms of pathogenic load along with the drug-resistance traits of the isolates, and detected the major virulent genes present in those isolates. Among the 30 such shrimp samples (15 each of Macrobrachium rosenbergi or Golda and Penaeus monodon or Bagda) studied, almost all were found to be contaminated with a huge load of bact...
