maternal carrier rates of potentially pathogenic organisms in bangkok, thailand.one hundred and four healthy women delivering infants at the royal thai army hospital, bangkok, were sampled by rectal swab for the laboratory isolation and identification of enteric bacteria of medical importance. seventeen percent of these women had significant isolates as salmonella, shigella and vibrio species. serotypically enteropathogenic escherichia coli were also identified in 31% of the mothers.19806996110
adherence as a method of differentiating virulent and avirulent strains of vibrio parahaemolyticus.usually only kanagawa-positive strains of vibrio parahaemolyticus are considered virulent; yet, a significant portion of v. parahaemolyticus food poisonings appear to be caused by kanagawa-negative strains. therefore, additional and more accurate measurements of a strain's food-poisoning potential are needed. adherence of v. parahaemolyticus to human fetal intestinal (hfi) cells in vitro seems to offer this information. all strains of v. parahaemolyticus adhered to the hfi cells, but the degree ...19806999994

seasonal distribution of bdellovibrios at the mouth of the patuxent river in the chesapeake bay.water samples taken at monthly intervals from three sites in the mouth of the patuxent river in the chesapeake bay were cultured for bdellovibrios lytic to vibrio parahaemolyticus and for total viable bacterial counts. the number of bdellovibrios recovered decreased from the spring months (april, may, june (amj) until very few were detected during the winter months (january, february, march (jfm), which also coincided with the lowest water temperatures. during the amj season there was a signific ...19827066762
scanning electron microscope observation of the swarming phenomenon of vibrio parahaemolyticus.scanning electron microscopy was used to study the production of lateral flagella and the swarming phenomenon in vibrio parahaemolyticus. differences in the size and diameter of the sheathed, polar flagellum and lateral flagella were apparent in these preparations. swarming of v. parahaemolyticus was found to be similar to the swarming of proteus spp. in that swarm cells which are heavily flagellated and elongated are formed.19827068539

incidence of vibrio species associated with blue crabs (callinectes sapidus) collected from galveston bay, texas.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 between the mean bacterial levels in the hemolymph of crabs collected during different seasons of the samplin ...19827103475
production of the kanagawa hemolysin by vibrio parahaemolyticus in a synthetic medium.a synthetic medium capable of supporting growth of vibrio parahaemolyticus is described. growth yields and generation times were comparable to growth in a complex medium, although kanagawa hemolysin was undetectable in the synthetic medium. upon the addition of single amino acids to this synthetic medium, only d-tryptophan induced production of the hemolysin. l-tryptophan was found to inhibit the action of the d-stereoisomer. the response to d-tryptophan was ph dependent; the greatest hemolysin ...19827107010
