| convulsions in childhood shigellosis. clinical and laboratory features in 153 children. | we studied 153 children who experienced convulsions associated with shigellosis. the male-female ratio was 1.2:1.0. thirty-six children had a previous history of febrile convulsions, and 31 children had a family history of convulsive disorder. most of the children were 0.5 to 3 years of age, although 49 (32%) were older than 3 years of age and 20 (13.1%) were older than 5 years of age. all children were febrile; in 75% of the children, the temperature was over 39 degrees c. the majority of the c ... | 1987 | 3544808 |
| [bacteriological study of shigellosis in the lake kivu area (central africa). developments in the last 15 years (1968-1983)]. | 1913 shigella strains were isolated from 1968 to 1983 in lake kivu area (central africa). distribution and evolution of serotypes, biotypes and antibiotypes were studied. the majority of serotypes and biotypes were stable. however, few of these strains showed variations, among them shigella dysenteriae serotype 1, causing epidemic dysenteriae since 1981. epidemiologic survey of shigellosis in kivu seems to be rather underdeveloped (4 bacteriology laboratories for an area of 10 million inhabitant ... | 1986 | 3542256 |
| clinical overview of alpha interferon. studies and future directions. | the clinical development of the alpha interferons has now progressed through initial phase i and ii trials into extensive controlled clinical trial designs. alpha interferon has been a prototype of other biological agents that are now in clinical development. these agents operate through fundamentally different mechanisms of action than conventional chemotherapy and have produced a unique profile of side effects as well as response patterns. time to response is generally longer than with chemoth ... | 2013 | 3542185 |
| isotope exchange at equilibrium studies with rat muscle adenylosuccinate synthetase. | the kinetic mechanism of rat muscle adenylosuccinate synthetase was studied by determining the rates of isotope exchange at equilibrium. a random sequential binding mechanism was indicated for both the forward and reverse reactions. aspartate, adenylosuccinate, gdp, and pi were determined to bind in rapid equilibrium. gtp exchanges with both gdp and pi at the same rate, which is similar to the exchange rate of imp with adenylosuccinate. aspartate exchanges with adenylosuccinate at a higher rate ... | 1986 | 3542024 |

| production of shiga toxin and other cytotoxins by serogroups of shigella. | we measured the cytotoxic activity of 119 strains of shigella by using a quantitative [3h]thymidine-labeled hela cell assay. we assayed 13 strains of shigella dysenteriae 1; 18 strains of s. dysenteriae types 2 and 3; and 88 strains of shigella sonnei, shigella flexneri, and shigella boydii. strains of s. dysenteriae 1 demonstrated high levels of cytotoxicity (geometric mean, 10(5.04) cd50/mg of protein; range, 10(3.95)-10(6.10). cytotoxic activities of the non-type 1 strains of s. dysenteriae a ... | 1986 | 3537154 |
| comparison of dna probes and the sereny test for identification of invasive shigella and escherichia coli strains. | forty-two shigella and 29 escherichia coli strains were screened for invasiveness in the sereny test and for hybridization with two recently described dna probes for the invasiveness plasmid. both probes produced identical results. all sereny-positive strains hybridized with both dna probes. three sereny-negative strains also hybridized with the probes, suggesting that there are strains containing the invasiveness plasmid that are not pathogenic in animal models. | 1986 | 3531233 |

| [conjugative r-plasmids simultaneously belonging to the 2 incompatibility groups inc i zeta and inc b]. | five plasmids detected in the clinical strains of shigella were studied. the plasmids had similar phenotypes of antibiotic resistance and allotted streptomycin and tetracycline resistance to the host cell. none of them allotted the bacterial cells with sensitivity to phages specific for the inc groups f, n, p and i. the molecular weights of the plasmids ranged from 47 to 50 md. the studies on the incompatibility showed that pkmr 227, pkmr 228-1, pkmr 231, pkmr 242-1 and pkmr 245 plasmids simulta ... | 1986 | 3521469 |
| [use of dna-dna hybridization methods for studying the epidemiology and evolutionary similarity of drug resistance determinants]. | a procedure for rapid mass assay of clinical strains of microorganisms based on dna-dna hybridization was developed. epidemiology of the gentamicin resistance determinant cloned earlier from clinical strains of the same hospital was studied and its plasmid localization in representatives of various genera of enterobacteriaceae was confirmed. the studies on dot-hybridization showed that in three antibiotic-producing organisms, i.e. s. fradiae 918 producing neomycin, m. purpurea 1535 producing gen ... | 2012 | 3521468 |
| the relation between production of cytotoxin and clinical features in shigellosis. | the relation between in vitro production of hela cell cytotoxin by strains of shigella and clinical symptomatology was determined for 35 travelers from the united states who developed shigellosis in guadalajara, mexico. there were 25 patients with shigella sonnei, eight with shigella flexneri, one with shigella boydii, and one with shigella dysenteriae. these strains were evaluated for in vitro production of cytotoxin. the amount of cytotoxin did not correlate with the number of stools passed, t ... | 1986 | 3519788 |
