| [prostaglandins and cyclic nucleotides in the gastrointestinal form of yersiniosis]. | in spite of the resemblance of the clinical picture of gastrointestinal yersiniosis and acute dysentery, material differences underlie the pathogenesis of these diseases. yersiniosis is marked by the predominance of an increase in the content of pgf2 alpha, whereas acute dysentery by an increase in the content of pge, which may be accounted for by greater intensity of the allergic manifestations in yersiniosis patients as compared with dysentery. shigellosis runs its course in the presence of th ... | 1989 | 2699095 |
| [bacterial etiological factors of diarrhea in the stool of infants hospitalized in january 1987]. | the results are presented of the second part of the studies conducted for monitoring of the variability of bacterial factors causing diarrhoea in the youngest children. the presently reported study comprised 42 babies aged from 7 days to 18 months treated in hospital in january 1987. the number of children with diarrhoea hospitalized in this period was relatively smaller than in january 1985, while the incidence of enteropathogenic bacteria in stools was very similar. they included mainly klebsi ... | 1989 | 2701337 |
| lcrh, a gene necessary for virulence of yersinia pestis and for the normal response of y. pestis to atp and calcium. | we are investigating the functions of the three proteins encoded by the v operon (lcrgvh) of the low-calcium response virulence plasmid pcd1 of yersinia pestis kim5. the purpose of this study was to define the role of the 18-kilodalton protein encoded by lcrh, the third gene of the v operon. using marker exchange mutagenesis, we constructed a y. pestis mutant that failed to express the lcrh protein. this lcrh- mutant was "atp blind" in that it failed to show altered growth and v-antigen expressi ... | 1989 | 2707857 |
| [prostaglandins and cyclic nucleotides in the dynamic development of an experimental poisoning syndrome caused by yersinia pestis lipopolysaccharide]. | this work deals with the influence of y. pestis lipopolysaccharide (lps), introduced intraperitoneally in a dose of 2 ld50, on the content of prostaglandins (pg), such as pge, pgf2 alpha and 6-keto-pgf1 alpha, thromboxane, camp and cgmp in the liver, lungs and blood plasma of guinea pigs in the process of the development of experimental intoxication. the content of thromboxane in blood plasma increased 2.4-fold in 2 hours after intoxication and remained elevated for as long as 5 hours. other par ... | 1989 | 2711790 |
| structural variations and growth potential of yersinia enterocolitica under different culture conditions. | the growth potential and the polypeptide composition of yersinia enterocolitica serotype 0:3 isolated from patients with uncomplicated diarrhoea, reactive arthritis or septicemia were evaluated under different culture conditions. the expression of polypeptides varied with presence of the virulence-associated 40-48 mdal plasmid, growth medium, growth temperature and gas composition of the culture (air, carbon dioxide, oxygen). also the initial growth medium at 26 degrees c, before temperature shi ... | 1989 | 2713134 |
| comparison of bacteria with and without plasmid-encoded proteins as antigens for measurement of immunoglobulin m, g, and a antibodies to yersinia enterocolitica by enzyme-linked immunosorbent assay. | yersinia enterocolitica serovar o:3 bacteria with and without plasmid-encoded proteins were compared as antigens in an enzyme-linked immunosorbent assay. good correlations between the two antigen preparations were obtained for immunoglobulin m (igm), igg, and iga antibodies of patients with yersiniosis. for routine diagnostic purposes, these antigens are considered equal. | 1989 | 2715330 |
| occurrence of yersinia enterocolitica in the tokyo tama zoo. | yersinia enterocolitica serogroups o5a and o8 were isolated from fecal samples of one colony of japanese macaques (macaca fuscata) from the tokyo tama zoo (japan). serogroup o5a was detected in brown bear (ursus arctos) prior to the isolation from the macaques. serogroup o5a organisms also were isolated from the japanese macaques' breeding area. serogroup o5a and o8 isolates were not pathogenic. serogroup o8 isolates did not possess the o7 or o19 antigens. | 1989 | 2716113 |
| [the study of intra-articular infectious agents in reactive arthritis]. | reactive arthritis is differentiated from infectious arthritis by the lack of intraarticular infectious agents. recently 2 groups, using different techniques have demonstrated intra-articular antigens in cases of reactive arthritis associated with chlamydia and yersinia infections. in this article we report the preliminary results of screening cells from synovial fluid for dna of certain microorganisms by in situ hybridization. our findings provide complementary evidence of the intra-articular p ... | 1989 | 2718145 |
