separation of active and inactive fractions from starved culture of vibrio parahaemolyticus by density dependent cell sorting.the co-existence of physiologically different cells in bacterial cultures is a general phenomenon. we have examined the applicability of the density dependent cell sorting (ddcs) method to separate subpopulations from a long-term starvation culture of vibrio parahaemolyticus. the cells were subjected to percoll density gradient and separated into 12 fractions of different buoyant densities, followed by measuring the cell numbers, culturability, respiratory activity and leucine incorporation acti ...200516329866
[symptoms of food-borne diseases and gastroenteritis in kyushu, japan].in this study we analyzed the symptoms of gastroenteritis or food-borne disease caused by the 10 most prevalent pathogens: norovirus, salmonella, vibrio parahaemolyticus, campylobacter jejuni, clostridium perfringens, shiga toxin-producing escherichia coli (stec), enterotoxigenic e. coli (etec), shigella sonnei/flexneri (shigella), staphylococcus aureus, and emetic-type bacillus cereus. the symptoms diarrhea, vomiting, fever, abdominal pain, and headache, and the incubation period in 646 cases i ...200516366357
the occurrence of vibrio species in tropical shrimp culture environments; implications for food safety.the occurrence of various vibrio species in water, sediment and shrimp samples from multiple shrimp farm environments from the east and west coast of india was studied. the relative abundance was higher in west coast farms (ca. 10(4) cfu/ml water) when compared to the east coast (ca. 10(2) cfu/ml water). vibrio alginolyticus (3-19%), v. parahaemolyticus (2-13%), v. harveyi (1-7%) and v. vulnificus (1-4%) were the predominant vibrio species identified by standard biochemical testing. in some case ...200515992615
identification of vibrio parahaemolyticus pandemic group-specific dna sequence by genomic subtraction.a genomic subtraction between a pandemic vibrio parahaemolyticus and a nonpandemic strain that seemed to be clonally related was performed. a subtractive dna fragment was identified to be a part of a 16-kbp insertion sequence which was present in almost all pandemic strains but not in nonpandemic strains tested.200516000499
development of a simple and rapid fluorogenic procedure for identification of vibrionaceae family members.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 synthetic substrate, and the membranes are examined for fluorescent foci under uv illumination. fluoresce ...200516000757
seasonal variation in abundance of total and pathogenic vibrio parahaemolyticus bacteria in oysters along the southwest coast of india.the seasonal abundance of vibrio parahaemolyticus in oysters from two estuaries along the southwest coast of india was studied by colony hybridization using nonradioactive labeled oligonucleotide probes. the density of total v. parahaemolyticus bacteria was determined using a probe binding to the tlh (thermolabile hemolysin) gene, and the density of pathogenic v. parahaemolyticus bacteria was determined by using a probe binding to the tdh (thermostable direct hemolysin) gene. furthermore, the pr ...200516000764
