Between 1996 and 2006, the US Centers for Disease Control reported that only category of food-borne infections increasing in frequency were those caused by members genus Vibrio. The Gram-negative bacterium Vibrio vulnificus is a ubiquitous inhabitant estuarine waters, number one cause seafood-related deaths US. Many V. isolates have been studied, it has shown two genetically distinct subtypes, distinguished 16S rDNA other gene polymorphisms, are associated predominantly with either...
ABSTRACT Despite years of successful isolation Vibrio vulnificus from estuarine waters, beginning in 2007, it was extremely difficult to culture V. either North Carolina water or oyster samples. After employing culture-based methods as well PCR and quantitative for the detection , always with negative results, we concluded that this pathogen had become nearly undetectable ecosystem. We ensured techniques were sound by seeding oysters performing same tests those previously conducted on...
ABSTRACT Marine aggregates are naturally forming conglomerations of larvacean houses, phytoplankton, microbes, and inorganics adhered together by exocellular polymers. In this study, we show in vitro that the bacterial pathogen Vibrio vulnificus can be concentrated into laboratory-generated from surrounding water. We further environmental (E-genotype) strains exhibit significantly more integration these than clinical (C-genotype) strains. Experiments where marine with attached V. cells were...
Commonly found in raw oysters, Vibrio vulnificus poses a serious health threat to immunocompromised individuals and those with serum iron overload, fatality rate of approximately 50%. An essential virulence factor is its capsular polysaccharide (CPS), which responsible for significant increase compared nonencapsulated strains. However, this bacterium known vary the amount CPS expressed on cell surface, converting from an opaque (Op) colony phenotype translucent (Tr) phenotype. In study,...
Monitoring of Vibrio vulnificus and V. parahaemolyticus abundance is pertinent due to the ability these species cause disease in humans through aquatic vectors. Previously, we performed a multiyear investigation tracking spp. levels five sites along southeastern North Carolina coast. From February 2013 October 2015, total was measured water, oysters clams. In current study, pathogenic subpopulations were identified isolates using molecular markers, revealing that 5.3% possessed...
ABSTRACT Filter feeding shellfish can concentrate pathogenic bacteria, including Vibrio vulnificus and parahaemolyticus , as much 100-fold from the overlying water. These shellfish, especially clams oysters, are often consumed raw, providing a route of entry for concentrated doses bacteria into human body. The numbers foodborne infections with these microbes increasing, better understanding conditions that might trigger elevated concentrations in seafood is needed. In addition, if bacterial...
A decade long study was conducted to investigate the ecological, biological, and temporal conditions that affect concentrations of Vibrio spp. bacteria in a well-studied lagoonal estuary. Water samples collected from Neuse River Estuary eastern North Carolina 2004-2014 (with additional follow-up Fall 2018) were analyzed determine concentrations, as well inorganic organic nutrients, fecal indicator bacteria, phytoplankton biomass, wide range other physio-chemical estuarine parameters....
The United States has federal regulations in place to reduce the risk of seafood-related infection caused by estuarine bacteria Vibrio vulnificus and parahaemolyticus. However, data support development have been generated a very few specific regions nation. More regionally are needed further understand dynamics human relating shellfish-harvesting conditions other areas. In this study, oysters water were collected from four oyster harvest sites North Carolina over an 11-month period. Samples...
ABSTRACT The bacterial pathogen Vibrio vulnificus is found naturally in brackish coastal waters but can be greatly concentrated by filter-feeding organisms such as shellfish. Numerous experiments which exogenous V. cells are added to oysters an attempt measure uptake and depuration have been performed. In nearly all cases, results shown that laboratory-grown bacteria rapidly taken up the ultimately eliminated, while present populations resistant depuration. this study, harvested during...
The human pathogen Vibrio vulnificus is a Gram-negative estuarine bacterium that infect via wounds and ingestion, the leading cause of seafood-borne death in United States. part naturally occurring flora both estuaries mollusks (especially oysters). divided into two genotypes, including clinically associated C-type, an environmentally E-type more rarely involved septicemia. These genotypes are found nearly even ratio aquatic environment, but oysters harvested from those very environments...
