| occurrence of vibrio parahaemolyticus in dutch mussels. | a study was carried out on the occurrence of vibrio parahaemolyticus in dutch mussels originating from the east schelde estuary. in a totol of 79 10-g tissue samples, 3 (3.8%) were found to contain v. parahaemolyticus. in a second survey, 6 out of 23 bags of mussels (26%) contained one or more strains of v. parahaemolyticus in 5-g tissue samples. the many limitations of current methodology used in such surveys are stressed. positive samples can be missed because viable cells may die during refri ... | 1979 | 453825 |
| inhibition by polyanions of adherence by kanagawa-positive vibrio parahaemolyticus: a physicochemical effect. | rapid adherence of kanagawa-positive vibrio parahaemolyticus to human fetal intestinal cells has been demonstrated in monolayer cultures. in this study, polyanionic carbohydrates and glycoproteins of various biochemical compositions, structural configurations, and molecular weights were found to inhibit this adherence. mono- and disaccharide components of inhibitory compounds did not themselves inhibit adherence. levels of ca++ in the test mixture were similar in both the presence and the absenc ... | 1979 | 458197 |

| [experimental study of vibrio parahaemolyticus (biotype 2) transfer from water and sediments to benthic marine food chain organisms]. | transfer of vibrio parahaemolyticus (biotype 2) from sediments to water and from water to benthic marine organisms was studied experimentally using a streptomycin-resistant strain. transmission by trophic pathways was also studied using reconstituted marine food chains (mytilus edulis, nereis diversicolor, carcinus maenas, scorpaena porcus, mus musculus). water colonization by sediments could be observed only at temperatures above 16 degrees c. sediments could well constitute a disseminating res ... | 1979 | 487292 |

| local tetanus in rats; concentration of amino acids as studied in spinal cord segments, spinal roots, and dorsal root ganglia. | 1. the effect of tetanus toxin injected into one gastrocnemius muscle on the steady state concentration of several amino acids was investigated in spinal cord half segments, spinal roots and dorsal root ganglia of rats. care was taken to ensure a symmetrical afferent input to the spinal cord and to localize the segment with the highest concentration of tetanus toxin. 2. in the spinal cord segments containing the highest concentration of tetanus toxin the steady state concentration of glycine was ... | 1979 | 492350 |
| investigation of an intracellular hemolytic agent of vibrio parahaemolyticus. lipid fraction of dried cells. | the dried cells of two strains of vibrio parahaemolyticus were fractionated by extracting first with water and then with organic solvents. the hemolytic activity of the fractions was determined, and some of them were assayed for their effect in mice. the hemolytic agent present in the water-insoluble fraction was extractable in organic solvents such as 70% aqueous ethanol, chloroform-methanol-water (1:2:0.8) and acetone. the extracts showed no toxic effect in mice after intraperitoneal inoculati ... | 1979 | 502896 |

| 2,3,7,8-tetrachlorodibenzo-p-dioxin: covalent binding of reactive metabolic intermediates principally to protein in vitro. | 2,3,7,8-tetrachlorodibenzo-p-dioxin (tcdd) is metabolized by the mouse liver cytochrome p-450-mediated monooxygenase system to reactive intermediates which bind 'covalently' to cellular macromolecules. although very difficult to quantitate, the presumably covalent binding to microsomal protein occurs between 120 and 2,640 times more readily than binding to deproteinized dna in the in vitro reaction. because of the extremely high rate of binding to protein rather than to dna, it is visualized tha ... | 1979 | 515166 |

| large animal hepatotoxic and nephrotoxic plants. | the hepatotoxic and nephrotoxic plants of large domestic animals have been reviewed. the most important ones are those widely distributed as weeds over pastures, negelcted forests and grasslands, those used as ornamentals, the nitrate concentrating forage crops, and the cyanophoric plants. crotolaria spp, the ragwort (senecia jacobaea), the lantana spp. and heliotopum are common hepatoxic plants. amaranthus retroflexus, datura stramonium, solanum rostratum, and the castor oil plant (ricinus comm ... | 1979 | 516370 |
