The Vibrio vulnificus aphB mutant was significantly less virulent than the wild type and was impaired in motility and adherence to host cells. Microarray analysis revealed that AphB of V. vulnificus (AphB(Vv)) influences the expression of over 10% of the V. vulnificus genome. The combined results indicated that AphB(Vv) is a global regulator contributing to the pathogenesis of V. vulnificus.

All Vibrio vulnificus strains tested (four clinical isolates and eight environmental isolates) hemolyzed human erythrocytes. In contrast to findings with Vibrio parahaemolyticus, in which hemolytic activity correlates with isolation from clinical specimens, results from the present study suggest that hemolysis is not usefull in differentiating V. vulnificus strains.

A 3-year environmental and clinical Vibrio vulnificus survey using simple-sequence repeats typing shows that V. vulnificus biotype 3 constitutes approximately 21% of the bacterium population in tested aquaculture ponds as opposed to approximately 86% of clinical cases. Simple-sequence repeats proved to be a useful epidemiologic tool, providing information on the environmental source of the path...

This study reported the incidence of potentially pathogenic Vibrio spp. in fresh seafood from Itu creek. Studies were carried out to isolate, identify and characterized different Vibrio species in fish, crayfish and periwinkle obtained from the Itu creeks. Different parts analyzed using standard microbiological techniques were the gills, intestine and the body surfaces. The Vibrio species isola...

Background: Seafood-borne Vibrio infections, often linked to contaminated seafood and water, are of increasing global public health concern. The aim of this study was to evaluate the prevalence of human pathogenic vibrios and their associated virulence genes isolated from fish and water samples from 2 commercial dusky kob farms and Kareiga estuary, South Africa. Methods: A total of 200 samples ...

Vibrio vulnificus (V. vulnificus) infection is a disease with serious health implications. Notably there are only about 50 confirmed cases of V. vulnificus per year but, the severity of the disease that is caused by this organism makes it the most pathogenic Vibrio. The organism is infamously associated with shellfish especially raw oysters and this could lead to the abated consumer confidence ...

A total of 209 pathogenic vibrios strains were isolated from Muthupettai mangrove environment, Southeast coast of India. All strains were identified to be 8 species (Vibrio cholera, Vibrio harveyi, Vibrio mimicus, Vibrio splendidus, Vibrio aestuarianus, Vibrio vulnificus, Vibrio parahaemolyticus and Vibrio metschnikovii) from all stations. The levels of resistance of bacteria to various antibio...

Vibrio vulnificus is an opportunistic human pathogen, transmitted from seawater, raw oyster, and shellfish and responsible for severe septicemia. We studied V. vulnificus from surface seawater around Jeju Island between 2010 and 2011. In 2010, V. vulnificus was isolated and V. vulnificus septicemia was reported. Surface seawater temperature is an important factor for growth of V. vulnificus, an...

Vibrio parahaemolyticus and Vibrio vulnificus are the major pathogenic Vibrio species which contaminate ready-to-eat seafood. The purpose of this study was to evaluate the risk of human illness resulting from consumption of ready-to-eat seafood such as sashimi and raw oyster meat due to the presence of V. parahaemolyticus and V. vulnificus. We compared the growth kinetics of V. parahaemolyticus...
