The production of a family of haemolysins--thermostable direct haemolysin (Vp-TDH), Vp-TDH-related haemolysin (Vp-TRH) and Vp-TDH/I--has been reported in clinical isolates of Vibrio parahaemolyticus. This paper describes a fourth type of haemolysin--Vp-TDH/II--produced by a Kanagawa phenomenon-negative clinical isolate of V. parahaemolyticus (O13:K, untypable). Vp-TDH/II was purified by ammonium sulphate precipitation and successive filtrations on DEAE-cellulose, hydroxyapatite, Sepharose 4B and Mono Q columns. Vp-TDH/II was biophysicochemically and immunologically similar to, but not identical to Vp-TDH, Vp-TRH and Vp-TDH/I. Vp-TDH/II stimulated vascular permeability in rabbit skin and was lethal to mice. Purified Vp-TDH/II and viable cells of the Vp-TDH/II-producing strain both induced fluid accumulation in ligated rabbit intestine. The plasmid-determined structural gene for Vp-TDH/II was cloned and the nucleotide sequence determined. The deduced amino acid sequence of Vp-TDH/II differed from those of Vp-TDH, Vp-TRH and Vp-TDH/I.

D011817 Rabbits A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.

D002199 Capillary Permeability The property of blood capillary ENDOTHELIUM that allows for the selective exchange of substances between the blood and surrounding tissues and through membranous barriers such as the BLOOD-AIR BARRIER; BLOOD-AQUEOUS BARRIER; BLOOD-BRAIN BARRIER; BLOOD-NERVE BARRIER; BLOOD-RETINAL BARRIER; and BLOOD-TESTIS BARRIER. Small lipid-soluble molecules such as carbon dioxide and oxygen move freely by diffusion. Water and water-soluble molecules cannot pass through the endothelial walls and are dependent on microscopic pores. These pores show narrow areas (TIGHT JUNCTIONS) which may limit large molecule movement.

D003001 Cloning, Molecular The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells.

D003967 Diarrhea An increased liquidity or decreased consistency of FECES, such as running stool. Fecal consistency is related to the ratio of water-holding capacity of insoluble solids to total water, rather than the amount of water present. Diarrhea is not hyperdefecation or increased fecal weight. Diarrheas
