[experimental study of the effectiveness of antibacterial preparations in treating dysentery].it was found that for successful elaboration of effective schemes for the use of antibacterial drugs in treatment of dysentery it was necessary to exploit various experimental models providing consideration of the drug toxicity and effect on the extra- and intracellular growth of the bacteria in addition to the other factors. the administration of enteroceptol for 3 days followed by furazolidon showed the best therapeutic effect in the treatment of guinea pigs with shigella keratoconjunctivitis ...1979156002
[use of intraspecific differentiation of sh. sonnei for the purpose of studying patterns in the epidemic process of dysentery].the use of complex typing of sh. sonnei by the colicinogenic and enzymatic properties in epidemiological analysis of dysentery caused by sh. sonnei, apart from establishment of epidemiological connections in the foci, offered a possibility of introducing significant corrections in the determination of the sizes and duration of existence of the epidemic foci, as well as in detection of the sources and factors of transmission of the infection established in epidemiological examination. typing of s ...1978154276

[comparative study on lymphocyte stimulation by pha and bacterial endotoxins, particularly in malignant tumor and allergy patients].in a group of 37 tumor patients with predominantly advanced disease, lps stimulation (lps of sh. sonnei and sh. flexneri) resulted in a significant increase of the transformation rates caused, most probably, by the high proportion of b cells. on the other hand, allergics (drug allergies) did not differ from controls. it seems possible that b cell stimulation by bacterial endotoxins can be used for the assessment of the reactivity of the organism.1976135504

salmonella choleraesuis proteins and their relation to proteins from bacteria of heterologous sero-groups.a diversity of proteins was identified in the material isolated from s. choleraesuis with the help of sera prepared in rabbits with this material. the sera displayed, in agar-gel diffusions, numerous superimposed precipitation lines against proteins from: salmonellae, shigellae and e. coli. in contrast to proteins from s. paratyphi c, sharing identical identical 'o' 'factors, the serological activity of the s. choleraesuis proteins was impaired by heating. the immunochemical analysis of the sera ...1979120926
lipid a from endotoxin: antigenic activities of purified fractions in liposomes.isolation of lipid a by acid hydrolysis of shigella flexneri lipopolysaccharide resulted in a product that consisted of a heterogeneous mixture of bands when visualized by thin layer chromatography. differential extraction with ethyl acetate and chloroform, or extraction with edta, followed by chloroform-methanol-water (bligh-dyer extraction), or a combination of both extraction schemes, resulted in partial purification of immunologically active lipid a. eight fractions were purified further by ...1979115918
action of bacterial endotoxin and lipid a on mitochondrial enzyme activities of cells in culture and subcellular fractions.escherichia coli o127:b8 lipopolysaccharide (lps), prepared by the westphal procedure, caused a marked decrease in the activities of mitochondrial malate dehydrogenase, succinate dehydrogenase, and adenylate kinase in african green monkey kidney (vero) cells and primary cultures of mouse liver cells within 2 h after exposure to 10 micrograms of lps/ml of culture medium. these three enzyme activities leaked into the supernatant fraction, and cytochrome oxidase activity was lost from the mouse liv ...1979114491

enteric infections in singapore with special reference to typhoid.a review of the epidemiological features of the more important enteric infections in singapore was given. enteric fevers (typhoid and paratyphoid), salmonella gastroenteritis and shigellosis remained endemic at a rather constant level in spite of vast improvement in environmental sanitation, but amoebic dysentery showed marked decline. vibrio parahaemolyticus is an important cause of food poisoning since it was first reported in 1973. el tor cholera is believed to be introduced through regional ...1978107597
homology of the gene coding for outer membrane lipoprotein within various gram-negative bacteria.the mrna for a major outer membrane lipoprotein from escherichia coli was found to hybridize specifically with one of the ecori and one of the hindiii restriction endonuclease-generated fragments of total dna from nine bacteria in the family enterobacteriaceae: e. coli, shigella dysenteriae, salmonella typhimurium, citrobacter freundii, klebsiella aerogenes, enterobacter aerogenes, edwardsiella tarda, serratia marcescens, and erwinia amylovora. however, among the enterobacteriaceae, dna from two ...1979104972
microbial impact of canada geese (branta canadensis) and whistling swans (cygnus columbianus columbianus) on aquatic ecosystems.quantitative and qualitative analyses of the intestinal bacterial flora of canada geese and whistling swans were carried out with the finding that wild birds harbor significantly more fecal coliforms than fecal streptococci. the reverse was typical of captive and fasting birds. neither salmonella spp. nor shigella spp. were isolated from 44 migratory waterfowl that were wintering in the chesapeake bay region. enteropathogenic escherichia coli were detected in seven birds. geese eliminated 10(7) ...1979104659
shigellosis and escherichia coli diarrhea: relative importance of invasive and toxigenic mechanisms.shigellae and dysentery-like escherichia coli must invade the epithelium of the colon to cause disease which can present as dysentery, diarrhea, or both. this paper addresses the possible role of a shigella dysenteriae-like (shiga-like) toxin in the pathogenesis of shigellosis and e. coli diarrheal diseases. the possibility for such a role is suggested by the following observations: 1) diarrhea, considered to be a result of secretion of water by the small bowel, is frequently observed in shigell ...1979104615
enterobacterial common antigen: isolation from shigella sonnei, purification and immunochemical characterization.in the studies presented the effective procedure of isolation and purification of enterobacterial common antigen from shigella sonnei has been elaborated. the method is based on sonification of bacterial suspension in the presence of lysozyme and edta and subsequent extraction of the pellet with boiling water. the crude extract of common antigen was purified by fractionation with ethanol and chromatography on silica gel and sephadex lh-20. the comparison of several extraction procedures of enter ...1978102511

sh. dysenteriae serotypes2,4,8-immunochemistry and phage receptor activity.among three analyzed serotypes of shigella dysenteriae, namely, the serotypes 2,4 and 8, the serotype 2 proved to be a strong immunogen in rabbits, inducing anti-polysaccharide antibodies as well as antiprotein antibodies in all the animals. in contrast, the serotypes 4 and 8 were weak immunogens and among the rabbits some have synthesized only anti-proteins while others had antibodies against the somatic conjugate. aside from the somatic antigens, large amounts of proteins were isolated from al ...197663197
studies on the pathogenesis of enteric infections caused by invasive bacteria.salmonellae, shigellae and some escherichia coli must invade the intestinal epithelial cell and multiply within the mucosa to cause disease. although the bacterial cell most likely possesses several properties essential to this invasive ability, the nature of the cell envelope complex is at present the only characteristic which has been implicated in this process. while a number of pathophysiological events result from invasion, some of our recent efforts have concerned the site and mechanism of ...197662646
