| mechanism of shigella entry into epithelial cells. | shigella, the causative agent of bacillary dysentery, invades epithelial cells by reorganizing the cell cytoskeleton during bacterial entry. this entry process requires the shigella ipa proteins that are secreted by a type iii secretion apparatus and that act in concert to fine tune cell responses. actin polymerization at the site of entry is dependent on the ipab and ipac proteins, whereas ipaa further modulates cytoskeletal rearrangements by binding to vinculin. | 1999 | 10047558 |
| comparison of six dose-response models for use with food-borne pathogens. | food-related illness in the united states is estimated to affect over six million people per year and cost the economy several billion dollars. these illnesses and costs could be reduced if minimum infectious doses were established and used as the basis of regulations and monitoring. however, standard methodologies for dose-response assessment are not yet formulated for microbial risk assessment. the objective of this study was to compare dose-response models for food-borne pathogens and determi ... | 1999 | 10765449 |
| [the role of the structural components of bacterial lipopolysaccharide in its inductive immunosuppressive activity]. | the inductive immunosuppressive activity of lipopolysaccharides (lps) and structural parts (o-chains,cor,lipid a) obtained from bacteria of the genus shigella and escherichia coli was studied. lps preparations were extracted by phenol-water method. its structural components were obtained by the acetic acid hydrolysis and gel filtration. it has been shown that all these preparations did not change the level of delayed type hypersensitivity (dth) to test-antigen in mice in the case of intraperiton ... | 1999 | 10707531 |
| cell adhesion molecules in the pathogenesis of and host defence against microbial infection. | eukaryotic cell adhesion molecules (cams) are used by various cells and extracellular molecules in host defence against infection. they are involved in many processes including recognition by circulating phagocytes of a site of inflammation, transmigration through the endothelial barrier, diapedesis through basement membrane and extracellular matrix, and release of effector mechanisms at the infected site. cams involved in leucocyte-endothelial cell interaction include the selectins, integrins, ... | 1999 | 10694943 |
| the seasonal variation in the microbial agents implicated in the etiology of diarrheal diseases among children in lao people's democratic republic. | during 1994-1995, the etiological structure of children's diarrhea was monitored in outpatients at mahosot hospital, vientiane, lao pdr. of the 191 children studied, 42% had stool specimens positive for enteropathogens; 22% had rotavirus, 21.5% enteropathogenic e. coli, 4.7% shigella flexneri, 2.9% campylobacter jejuni, 2.1% shigella sonnei, and 0.5% each of giardia intestinalis and entamoeba histolytica. no vibrio cholerae and salmonella spp. was detected in this monitoring. in children under f ... | 1999 | 10774703 |

| survival of some species of salmonella and shigella in mukumbi, a traditional zimbabwean wine. | mukumbi is a traditional zimbabwean wine prepared from a fruit called mapfura by the shona people of zimbabwe and amaganu by the ndebele. the majority of people in africa call the tree marula (sclerocarya birrea subspecies caffra). the survival of salmonella group b, salmonella enteritidis, shigella sonnei and shigella flexneri in unfermented and fermented mapfura (marula) juice (mukumbi) was investigated. it was found that within 30 min of inoculation, there were no longer any viable pathogens ... | 1999 | 10719586 |
| [diarrheal disease among caregivers at children's day-care centers. a retrospective and seroepidemiologic study]. | diarrheal disease tends to spread from infected children to their families. due to the increased risk of exposure, children's caregivers in day-care centers may have a higher incidence of diarrhea, particularly when caring for very young children. we therefore examined the incidence of diarrhea and antibodies to shigella among caregivers in day-care centers, according to age groups of children in their care (< 18, 18-34, and > 35 months) and in comparison with the general population. 2 studies w ... | 1999 | 10914170 |

| inorganic polyphosphate: a molecule of many functions. | inorganic polyphosphate (poly p) is a chain of tens or many hundreds of phosphate (pi) residues linked by high-energy phosphoanhydride bonds. despite inorganic polyphosphate's ubiquity--found in every cell in nature and likely conserved from prebiotic times--this polymer has been given scant attention. among the reasons for this neglect of poly p have been the lack of sensitive, definitive, and facile analytical methods to assess its concentration in biological sources and the consequent lack of ... | 1999 | 10872445 |
| [shigellosis and other acute intestinal infections in the republic of tajikistan: the epidemiological patterns]. | acute enteric infections (aei), including shigellosis, are characterized by their extremely wide spread in tajikistan. their hyperendemicity is due to a high activity of the water route of transmission under the conditions of hot climate. the morbidity level of aei both in the republic as a whole and in its individual territories has been found to directly depend on the degree of the potential epidemiological danger of the water supply system, as well as on the quality of water used by the popul ... | 1999 | 10876848 |
| inhibition of shigella flexneri-induced transepithelial migration of polymorphonuclear leucocytes by cadaverine. | dysentery caused by shigella species is characterized by infiltration of polymorphonuclear leucocytes (pmns) into the colonic mucosa. shigella spp. evolved into pathogens by the acquisition of virulence genes and by the deletion of 'antivirulence' genes detrimental to its pathogenic lifestyle. an example is cada (encoding lysine decarboxylase), which is uniformly absent in shigella spp., whereas it is present in nearly all isolates of the closely related non-pathogen escherichia coli. here, usin ... | 1999 | 11207548 |
| the secreted ipab and ipac invasins and their cytoplasmic chaperone ipgc are required for intercellular dissemination of shigella flexneri. | invasion of epithelial cells by shigella flexneri involves entry and dissemination. the main effectors of entry, ipab and ipac, are also required for contact haemolytic activity and escape from the phagosome in infected macrophages. these proteins are stored in the cytoplasm in association with the chaperone ipgc, before their secretion by a type iii secretion apparatus is activated by host cells. we used a his-tagged ipgc protein to purify ipgc-containing complexes and showed that only ipab and ... | 1999 | 11207551 |
| pathogenic effects of opolysaccharide from shigella flexneri strain. | aim:to investigate the specific pathogenesis of o-polysaccharide (o-ps) which is on the outer membrane of lipopolysaccharides (lps) from shigella flexneri.methods:the o-ps was isolated and purified from shigella flexneri 5 m90t by enzymatic hydrolysis and gel chromatography. effects of o-ps were observed by in vitro experiment, (hela cell culture), and in vivo experiment (rabbit ileal loop assay).results:in vitro and in vivo experiments with the purified o-ps from shigella flexneri revealed that ... | 1999 | 11819440 |
| virulence factors of salmonella ser. enteritidis strains isolated in italy from food-borne outbreaks. | twelve salmonella ser. enteritidis strains phage type 4 isolated in italy from different food-borne outbreaks were characterized for the expression of different virulence traits, for antibiotic resistance, and for plasmid dna profile. all the twelve s. enteritidis strains were able to invade and multiply within hela cell monolayers, even if at a lower efficiency if compared to an invasive shigella flexneri strain. the strains were not hemolytic and produced only a moderate-level cytotoxic effect ... | 1999 | 12783651 |

| [renewal of noradrenaline in different zones of the central nervous system of inbred mice strains and their recombinants]. | a good correlation exists between the learning capacity and norepinephrine metabolism in the neocortex of c57 and balb inbred mice strains, as well as their f1 hybrids and seven recombinant inbred strains derived from their cross. the animals with a better learning performance are characterised by low levels of norepinephrine, as well as a slow metabolic rate of this neurotransmitter in the cortex. such a correlation has not been found to exist in the other cerebral regions studied. | 1999 | 96976 |
| group systems of serum proteins and erythrocyte enzymes in malignant lymphoma. | four group systems of serum proteins (hp, gc, gm, km) and five group systems of erythrocyte enzymes (ap, pgm1, gpt, ak, esd) were determined in 63 patients with malignant lymphoma. statistical analysis of the distribution of the above mentioned systems in patients and polish population samples did not reveal any significant differences, which points to the lack of any correlation between the disease and the group systems under examination. | 1999 | 85572 |

| composition and potential use of some tropical fruits. | the nutritional role fruits could play in poor-quality diets, as sources of vitamin a and ascorbic acid, is described. likewise, summarized information is presented on the use of some unknown tropical fruits relatively abundant in central america as components of high-protein foods, providing nutrients such as provitamin a and ascorbic acid, as well as a variety of flavors. in these studies the fruit pulp as a purée was added either fresh or drum-dried, to a corn-soybean blend. in all cases ther ... | 1999 | 96749 |
| diagnosis and staging of prostatic cancer by transrectal ultrasonography. a preliminary study. | sixty men (7 normal, 53 with prostatic disease) underwent transrectal ultrasonic scanning of their prostates in order to assess the technique and evaluate its reliability in the detection and staging of prostatic cancer. the prostatic capsule was clearly seen in 58 men; non-integrity of the capsule occurred only in those with proven cancer (17 cases). an ultrasound diagnosis of cancer was made for 32 of 33 men with proven disease and it was shown that ultrasound demonstrated anterior perforation ... | 1999 | 93975 |

| malignant fibrous histocytoma producing spinal cord compression. | three cases of malignant fibrous histiocytoma presented as primary paraspinal tumours causing extradural spinal cord compression. study of these cases suggests that pain relief is considerable after laminectomy but pain may recur with further tumour growth. total removal is unrealistic and diagnosis, difficult. the prognosis in terms of continuing neurological deficit after surgery followed by local radiotherapy appears poor. | 1999 | 91666 |
| [value and limit of photocoagulation for juxtafoveolar sub-retinal vessels (author's transl)]. | sub-retinal new vessels arising from the choroid are the most dangerous components in disciform maculopathies. the greatest advance made in their treatment has been due to the use of photocoagulation over the last few years, but their destruction by this method is still a very controversial subject. the aim of the present study was to define which lesions should be treated and which should not. results demonstrated that the use of photocoagulation to destroy new vascular membrane which is very c ... | 1999 | 94069 |
