Characterization of the pili isolated from Vibrio parahaemolyticus O3:K6.
Pilus of Vibrio parahaemolyticus O3:K6 strain LVP9 belonging to the newly identified clone was purified and characterized. The molecular mass of the pilin was estimated to be about 18 kDa by SDS-PAGE, and the isoelectric point of the pilin was 5.0 +/- 0.2. The LVP9 pili were antigenically different from the other V. parahaemolyticus Na2 pili and Ha7 pili as previously reported, nevertheless all...
متن کاملCharacterization of Pathogenic Vibrio parahaemolyticus from the Chesapeake Bay, Maryland
Vibrio parahaemolyticus is the leading cause of bacterial gastroenteritis associated with seafood consumption in the United States. Here we investigated the presence of virulence factors and genetic diversity of V. parahaemolyticus isolated from water, oyster, and sediment samples from the Chesapeake Bay, Maryland. Of more than 2,350 presumptive Vibrio collected, more than half were confirmed t...
متن کاملMolecular confirmation and characterization of Vibrio parahaemolyticus from retailed fish
The present study was conducted to assess the rapid molecular identification and characterization of 45 Vibrio parahaemolyticus isolates from 15 samples of 3 different types of fish (Kembung, Bawal and Sangeh) in the Kuching-Samarahan district. Polymerase chain reaction (PCR) based confirmation was done targeting the 450 bp fragment of the thermolabile (tl) gene, while DNA fingerprinting was pe...
متن کاملMassively parallel characterization of restriction endonucleases
Restriction endonucleases are highly specific in recognizing the particular DNA sequence they act on. However, their activity is affected by sequence context, enzyme concentration and buffer composition. Changes in these factors may lead to either ineffective cleavage at the cognate restriction site or relaxed specificity allowing cleavage of degenerate 'star' sites. Additionally, uncharacteriz...
متن کاملStudy of capsular polysaccharide from Vibrio parahaemolyticus.
The leading cause of food poisoning in both Taiwan and Japan is Vibrio parahaemolyticus infection, whose mechanism of enteropathogenesis is still unclear. To evaluate whether surface components are responsible for the intestinal adhesion of V. parahaemolyticus, we have developed a novel method for isolating the capsular polysaccharide (CPS) from V. parahaemolyticus (serotype O4:K8). We found th...
