| bacterial plasminogen receptors: in vitro evidence for a role in degradation of the mammalian extracellular matrix. | the potential of bacterium-bound plasmin to degrade mammalian extracellular matrix and to enhance bacterial penetration through basement membrane was assessed with the adherent strain sh401-1 of salmonella enterica serovar typhimurium. typhimurium sh401-1 was able to bind plasminogen and to enhance the tissue-type plasminogen activator-mediated activation of the single-chain plasminogen to the two-chain plasmin. the end product, the enzymatically active, bacterium-bound plasmin activity, was als ... | 1995 | 7642304 |
| relationship between evolutionary rate and cellular location among the inv/spa invasion proteins of salmonella enterica. | for 21 strains of salmonella enterica, nucleotide sequences were obtained for three invasion genes, spao, spap, and spaq, of the chromosomal inv/spa complex, the products of which form a protein export system required for entry of the bacteria into nonphagocytic host cells. these genes are present in all eight subspecies of the salmonellae, and homologues occur in a variety of other bacteria, including the enteric pathogens shigella and yersinia, in which they are plasmid borne. evolutionary div ... | 1995 | 7638176 |
| [study of 2 food poisoning outbreaks in mora (toledo) with the same source of infection]. | the occurrence of an outbreak needs an immediate investigation, because on it depends the necessary measures to control the spread of the epidemic, and it is also the way of knowing the causal factor. we present the results of the investigation of two food poisoning outbreaks (outbreak a and outbreak b) occurred in mora (toledo). both outbreaks were reported at the same time, the source of infection was the same and the total number of exposed people was 620. | 1994 | 7618037 |
| transcriptional regulation and promoter sequence of the spvr gene of virulence plasmid pkdsc50 in salmonella choleraesuis serovar choleraesuis. | the transcript of the spvr gene on the virulence plasmid, pkdsc50, of salmonella choleraesuis serovar choleraesuis was detected for the first time by northern blot analysis, and the transcriptional regulation of the spvr gene was investigated. the transcription of the spvr was negatively regulated by spva and spvb, and enhanced at stationary phase under control of a sigma factor rpos (sigma 38). the spvr transcript was 2.4 kilonucleotides in salmonella cells, and deduced to encode spvr and spva, ... | 1995 | 7607404 |
| sequence and analysis of the o antigen gene (rfb) cluster of escherichia coli o111. | the o antigens found in salmonella enterica (se) and escherichia coli (ec) show a great deal of diversity, and only three structures are known to be common to both genera. two of them contain the 3,6-dideoxyheoxse colitose, not found in other serogroups of the two species. the first of these is common to ec o111 and se o:35 (sv adelaide); the other is found in both ec o55 and se o:50 (sv greenside). the genes specific for the synthesis of o antigen are generally located in the rfb gene cluster a ... | 1995 | 7590310 |
| hard surface carrier test as a quantitative test of disinfection: a collaborative study. | the hard surface carrier test (hsct) recently was proposed as a qualitative test for disinfectant efficacy. a collaborative study of hsct led to a suggested performance standard of < or = 2 or 3 positive carriers out of 60 tested. subsequently, it was discovered that hsct can be used as a quantitative test, because the hsct protocol requires measurement of inoculum level on some carriers. the data allow estimation of the log10 reduction in number of active bacteria. producers, consumers, and pol ... | 1995 | 7580324 |
| effects of in vivo administration of anti-il-10 monoclonal antibody on the host defence mechanism against murine salmonella infection. | interleukin-10 (il-10) is a cytokine that regulates various macrophage functions. to elucidate the involvement of endogenous il-10 in the early stage of murine salmonellosis, we examined the effect of anti-il-10 monoclonal antibody (mab) administration on the host defence mechanism against salmonella choleraesuis infection. the in vivo administration of anti-il-10 mab significantly enhanced host resistance at the early stage of salmonella infection, as assessed by bacterial growth in the periton ... | 1995 | 7558125 |
| lateral transfer of rfb genes: a mobilizable cole1-type plasmid carries the rfbo:54 (o:54 antigen biosynthesis) gene cluster from salmonella enterica serovar borreze. | plasmid pwq799 is a 6.9-kb plasmid isolated from salmonella enterica serovar borreze. our previous studies have shown that the plasmid contains a functional biosynthetic gene cluster for the expression of the o:54 lipopolysaccharide o-antigen of this serovar. the minimal replicon functions of pwq799 have been defined, and a comparison with nucleotide and protein databases revealed this replicon to be virtually identical to cole1. this is the first report of involvement of cole1-related plasmids ... | 1995 | 7545154 |
| transferases of o-antigen biosynthesis in salmonella enterica: dideoxyhexosyltransferases of groups b and c2 and acetyltransferase of group c2. | the o antigen is a polymer of oligosaccharide units. o antigens differ in their sugar composition and glycosidic linkages, and genes responsible for o-antigen-specific biosynthesis are grouped in the rfb gene cluster. in this study, we identified two abequosyltransferase genes and an acetyltransferase gene in salmonella enterica groups b and c2 by in vitro assay and identified paratosyl-, tyvelosyl-, and abequosyltransferase genes from s. enterica groups a and d and yersinia pseudotuberculosis s ... | 1995 | 7541787 |
| molecular, genetic, and topological characterization of o-antigen chain length regulation in shigella flexneri. | the rfb region of shigella flexneri encodes the proteins required to synthesize the o-antigen component of its cell surface lipopolysaccharides (lps). we have previously reported that a region adjacent to rfb was involved in regulating the length distribution of the o-antigen polysaccharide chains (d. f. macpherson et al., mol. microbiol. 5:1491-1499, 1991). the gene responsible has been identified in escherichia coli o75 (called rol [r. a. batchelor et al., j. bacteriol. 173:5699-5704, 1991]) a ... | 1995 | 7532168 |
| usefulness of molecular genetic markers in the typing of salmonella enterica serovar enteritidis causing a food-borne outbreak. | a combination of serotyping-phagetyping and three molecular genetic markers (plasmid analysis, chromosomic dna restriction pattern and ribosomal rna gene restriction pattern or ribotyping) was used in the typing of salmonella enterica causing a food-borne outbreak. the isolates analysed, 29 from stools and eight from foods, belonging to serovar enteritidis-phagetype a, carried a 36-mda plasmid, showed a similar dna restriction pattern and the same ribopattern. these data indicate that only one s ... | 1994 | 7521196 |
| involvement of the galactosyl-1-phosphate transferase encoded by the salmonella enterica rfbp gene in o-antigen subunit processing. | rfbt of salmonella enterica lt2 was previously thought, together with rfal, to be involved in the ligation of polymerized o antigen to core-lipid a, and three mutants were known. we report the mapping of the mutations to rfbp, the galactosyl-1-phosphate transferase gene, which is now shown to encode a bifunctional protein. the mutations which have the former rfbt phenotype are referred to as rfbp(t). we also show that rfbp(t) mutants are not blocked in the ligation step as previously believed bu ... | 1994 | 7517393 |
| genetic analysis of the o-specific lipopolysaccharide biosynthesis region (rfb) of escherichia coli k-12 w3110: identification of genes that confer group 6 specificity to shigella flexneri serotypes y and 4a. | we recently reported a novel genetic locus located in the sbcb-his region of the chromosomal map of escherichia coli k-12 which directs the expression of group 6-positive phenotype in shigella flexneri lipopolysaccharide, presumably due to the transfer of o-acetyl groups onto rhamnose residues of the s. flexneri o-specific polysaccharide (z. yao, h. liu, and m. a. valvano, j. bacteriol. 174:7500-7508, 1992). in this study, we identified the genetic region encoding group 6 specificity as part of ... | 1994 | 7517390 |
