genetic basis of vi antigen expression in salmonella paratyphi c.	analysis of hybrids formed in a cross between a salmonella paratyphi c hfr and an s. typhimurium recipient indicated that the structural genetic determinants of the s. paratyphi c vi antigen are located closely adjacent to the mel determinant, between this marker and pura. a similar location was indicated for the structural genetic determinants of the s. typhi vi antigen (the viab locus) by the results of a mating in which a hybrid s. typhimurium hfr bearing the s. typhi viab determinants was us ...	1977	68953

the serological specificities of salmonella typhi antigens.	sera prepared with two different strains of salmonella typhi were analysed against all the soluble antigens isolated from s. typhi 0901, s. typhi ty2 and s. typhi vi. agar-gel diffusion against individual sera showed that, in all the sera, antibodies were induced against somatic antigens and free proteins. absorptions of the sera with polysaccharides, split from the somatic antigens, removed the antibodies induced against the polysaccharide and its proteinic carrier in most of the somatic antige ...	1976	69247
immunization with r mutants of salmonella minnesota. ii. serological response to lipid a and the lipopolysaccharide of re mutants.	rabbits were immunized with salmonella minnesota re mutant bacilli or lipid a, and the serological responses were compared. re lipopolysaccharide and lipid a were found to possess distinct antigenic determinants as measured by hemagglutination, hemolysis, and precipitin techniques. lipid a preparations from several enterobacterial and non-enterobacterial species were shown to cross-react in agar gel precipitation reactions. in contrast, preparations from bacilli that do not contain glucosamine a ...	1977	69613

reduced active thyroid hormone levels in acute illness.	in acute and subacute disease the active thyroid hormones, triiodothyronine (t3) and tetraiodothyroacetic acid (tetrac), are decreased while serum-thyroxine (t4) levels tend to be slightly reduced. conversely, the inactive metabolite, reverse triiodothyronine (reverse t3), is increased indicating a diversion of t4 metabolism from an activating to an inactivating pathway. with convalescence the serum levels of t3, tetrac, and t4 recover while reverse t3 decreases to normal. these changes occur wi ...	1976	73636

impairment of the immune response to vaccination after acute malaria.	children with acute malaria were vaccinated with salmonella typhi and meningococcal vaccines at varying times after the onset of their illness. the immune response to both vaccines was depressed when they were given on the day of presentation at hospital. immune responsiveness to s. typhi vaccine was rapidly regained after treatment, but a month after the attack the immune response to meningococcal vaccine was still impaired.	1978	78096
automation of salmonella typhi phage typing.	two steps in the procedure for bacteriophage typing of salmonella typhi have been automated. the culture inoculum was applied by flooding the surface of phage agar in a 150x20 mm petri dish and removing the excess liquid with a safety pipettor. this step replaced the older method of manually preparing up to 100 individual areas for inoculation. the number of bacteria per unit area was the same with both methods, so the automated method involved no change in the technique. the second automated st ...	1975	78153

ribonucleic acid in the immune response.	in the studies of experimental salmonellosis, immunization of mice with a live vaccine ser of s. enteritidis was found to be effective against further infection with virulent s. enteritidis 116--54. macrophages obtained from the peritoneal cavity, subcutaneous tissue or liver of immunized mice inhibited intracellular growth of bacteria and resisted cell degeneration caused by engulfment of virulent 116--54 bacteria. this immunity was called cellular immunity. we discovered by chance in 1961 a tr ...	1978	81465

genetic properties of the salmonella enteritidis r404 plasmid aggregate. ii. separation of plasmids by transformation.	transformational separation of plasmids from r404 plasmid aggregate found in salmonella enteritidis strain was performed. three classes of transformants differing in their resistance patterns were isolated. genetic properties of the transformants suggest that their resistance is determined by single plasmids. plasmid pck3 (tra-apcbcrsusm) and pck4 (tra-apcbcrcm) are nonconjugative while plasmid pcg1 (traapcbcrsusmtckmnm) is conjugative. separation of all plasmids of r404 plasmid aggregate allowe ...	1978	81594

endotoxins of anaerobic gram-negative rods.	endotoxic lipopolysaccharides (lps) isolated from fusobacterium are similar to those of salmonella with respect to chemical composition, o-antigenic specificity and endotoxic activity. bacteroides lps are highly atypical with respect to the chemical composition, and their endotoxic activity is low. o-antigenic specificity is present. b. fragilis lps is chemotactic for polymorphonuclear leukocytes in vitro and in vivo. the chemotactic activity is brought about by activation of the alternative com ...	1979	88759

immune response deficiency of bsvs mice. ii. generalized deficiency to thymus-dependent antigens.	bsvs mice gave abnormally low igg responses to 5 thymus-dependent antigens as well as a weak delayed-type hypersensitivity (dth) response to sheep red blood cells. in contrast to igg, the igm antibody responses of these mice were normal to three t-independent antigens as well as to all five t-dependent antigens. the low immune responsiveness of bsvs mice was also reflected in the low levels of igg(2)a, igg(2)b and igg(3) in their normal serum. the low t-dependent immune responses may result from ...	1979	89033

a comparison of the antibacterial properties of some udder creams and ointments.	the antibacterial activity of three udder creams and two ointments was assayed using three different methods. seven different bacterial genera were used as test organisms providing a total of 17 strains. only a single strain of corynebacterium was inhibited by all the preparations. certain strains of staphylococci and streptococci were inhibited by four of the preparations. the gram-negative organisms showed greatest resistance to the antibacterial agents tested. the in vitro assays showed only ...	1979	89750
m467: a murine iga myeloma protein that binds a bacterial protein. i. recognition of common antigenic determinants on salmonella flagellins.	we have studied the binding of m467, an iga murine myeloma protein, to flagellin from seven species of salmonella. it was found that m467 was reacting with antigenic determinants that were common to all the flagellins studied. these determinants were not related to serotypic antigens. electronmicrographs of unreduced m467 showed a variety of polymeric species bound to flagella in a manner that could produce immobilization as well as agglutination and precipitation through cross-linking of antige ...	1979	90100
specificity of antipyrogenic immunity.	the specificity of antipyrogenic immunity as well as the structural differences of the enterobacteria responsible for pyrogenicity have been studied. strains s. minnesota re 595 and s. typhimurium sl 1102 as well as glycolipids obtained from them, further e. coli 083 and e. coli f 576 as well as the lps extracted from them were used in the experiments. in conformity with the results of chemical analysis it was found that the method reflected exactly the antigenicity of the receptors responsible ...	1978	90447
