direct selection of mutations reducing transcription or translation of the reca gene of escherichia coli with a reca-lacz protein fusion.when a reca-lacz protein fusion was cloned into phage lambda, the resulting transducing phage grew normally on wild-type escherichia coli, but its growth was severely inhibited in lexa(def) mutant strains that express reca constitutively at high levels. mutants of the transducing phage that grew on the lexa(def) strains were isolated and were found to affect production of the reca-beta-galactosidase hybrid protein. most mutants, including a number of nonsense mutants, were phenotypically lacz-. ...19853160689
structural and functional studies of the effects of sympathetic nerve stimulation on rabbit submandibular salivary glands.continuous sympathetic stimulation at 8-10 hz caused intense vasoconstriction in the gland, so stimulation was generally given in an interrupted pattern to minimize this detrimental effect on secretion. only a small increase in fluid secretion occurred; it became thick and tended to block the cannula; therefore in later experiments the main duct was not cannulated. after sympathetic stimulation there was substantial degranulation of acinar cells. however, as this was accompanied by little moveme ...19883165262
coagglutination of vibrio cholerae, vibrio mimicus, and vibrio vulnificus with anti-flagellar monoclonal antibody.monoclonal antibodies (mabs) with serological activity for purified flagellar (h) core protein prepared from vibrio cholerae were identified by enzyme-linked immunosorbent assay. four of these mabs reacted with the flagella of v. cholerae and v. mimicus exclusively, while eight mabs reacted with at least 1 of 30 heterologous vibrio species tested by enzyme-linked immunosorbent assay or coagglutination. it appears that v. cholerae and v. mimicus express similar, if not identical, h determinants u ...19883182988
studies on the factors affecting the haemolysin production of vibrio mimicus isolated from clinical and environmental sources.the in vitro production of haemolysin by vibrio mimicus, a newly described aetiological agent for human diarrhoea, was determined using sheep erythrocytes. the effects of medium composition and sodium chloride concentration on haemolysin production and its heat stability were investigated. the haemolysin was produced optimally in brain-heart infusion broth and was unaffected by salt concentration up to 1.5%. however, haemolysin production decreased gradually with increasing concentrations of sal ...19883188168
