the numerous common antigens of enterobacteriaceae.a mosaic of proteins is synthesized by each of the enterobacterial species grown on artificial media (tryptose-agar, difco). their existence was proven with the help of sera prepared in rabbits with proteins from: s. enteritidis, s. typhi, s. typhimurium, s. paratyphi c, e. coli, and sh. sonnei. the induced antibodies, strongly precipitated numerous heterologous enterobacterial proteins. the proteins of sh. dysenteriae 4, although reacting against the heterologous sera, were poor immunogens and ...1979388941
epidemiology of shigella dysenteriae, type 1 infections, in dacca urban area.a prospective study of 47 families with an index case of shigella dysenteriae type 1 was conducted in the urban areas of dacca. the subsequent infection rates in contacts type 1 were 30.6% and 28.3% in the age groups 0--4 and 5--9. total secondary infection rate was 20.4% with rates in males higher than in females. among the contacts 12.5% developed diarrhoea caused by the same serotype, but 22.1% developed diarrhoea with undiagnosed causes. for one hospitalised case there were seven symptomatic ...1979388775

characterization of plasmids from antibiotic-resistant shigella isolates by agarose gell electrophoresis.gel electrophoresis of dna from 95 clinical isolates of shigella sonnei and shigella flexneri resistant to antibiotics revealed a heterogeneous plasmid population. most of the plasmids were smaller than 6 megadaltons (mdal). six s. sonnei isolates with the most common antibiotic resistance pattern were characterized. they had two plasmids in common: one was a self-transmissible fi+ plasmid of 46 mdal encoding resistance to streptomycin and sulphafurazole. in addition, several cryptic plasmids ra ...1979387914
[functional interactions of the genomes of shigella sonnei phages and escherichia coli phage t4 in mixed infection].a comparative study of shigella sonnei phages u and g and escherichia coli phage t4 has shown that enzymes coded for by the sh. sonnei phages can functionally substitute for some t4-coded products. this finding in indicative of an evolutionary relationship between t-even phages and disenteric phages u and g. the u phage is uncapable to compensate amber mutants for the genes that control the conversion of cytosine into 5-hydroxymethyl cytosine (5-hmc) and the glucosylation of the latter, which ag ...1979387521

shigella infections.shigellosis is a complex disease involving two distinct organs and two distinctive clinical presentations of intestinal involvement. it is also associated with a wide variety of extra-intestinal manifestations. because these may precede the onset of diarrhoea/dysentery, and confuse the diagnosis, it is safe to denote shigellosis as a protean clinical problem. the disease is readily spread by contact because so few organisms are required to establish infection. it may also be spread through conta ...1979387300
[results of testing a new method of using antibiotics in nutrient media for the isolation of shigella: the 2-streak method].a new variant of media with antibiotics for isolation of shigella, i.e. a method of 2 streaks each containing different antibiotics was tested in analysis of excrements from patients with acute dysentery. it was found that the new method is more effective than the well known method of gradient plates (isolation of shigella in one series of the experiments amounted to 85.2 and 64.7 per cent respectively, and in the other series of the experiments the respective figures were 95.4 and 89.3 per cent ...1979386936

[seasonal problems of bacterial dysentery in the dagestan assr].during the period of 1959-1973 bacterial dysentery showed high morbidity rate in daghestan in all seasons, this tendency existing both in urban and rural areas. the peculiarity of the monthly distribution of dysentery cases, observed all over the repulic, was the shift of the morbidity peak from august to september-october, and in some years even to november; this could be clearly observed from the analysis of the material as a whole and from the analysis of dysentery morbidity rates in rural an ...1979386661
[recurrent sonne dysentery morbidity caused by shigella of varying enzymatic types].the proportion of repeated cases of dysentery caused by sh. sonnei does not exceed 3.59% of the total number of bacteriologically confirmed cases of this infection. the frequency of reinfection depended on the enzymatic type of the causative agent. the rarest cases of reinfection were those occurring after the primary infection with sh. sonnei, biochemical type 2, whereas the most frequent after the primary infection with sh. sonnei, type 3. reinfection with heterologous sh. sonnei was registere ...1979386653

[phage-typing modifications induced by in vitro transfer of r plasmids. ii. -- phage-typing of shigella sonnei (author's transl)].forty-two antibiotic resistance plasmids and twelve metabolic plasmids have been transferred to a strain of shigella sonnei. the phage-typing modifications have been investigated after transfer of the different above described plasmids. eleven of the r plasmids and five of the metabolic plasmids affect phage sensitivity. these modifications are not specific for any compatibility group.1979384862
[survey of antibiotic resistance in gram-negative bacteria using the cross product ratio].antibiotic resistance pattern in clinical isolates of selected gram-negative bacteria at groote schuur hospital during two three-month periods with a ten year interval were investigated. the antibiotic resistance is represented by means of the cross product, or odds ratio, using the log-linear model. this was found to be a simple method of monitoring the change or increase of antibiotic resistance, and enabled an overall analysis, catering for antibiotic and organism effects, to be performed1979384718
clinical profile of diarrhoea at ramathibodi hospital during 1977.restrospective clinical profile of diarrhoeal disease in children admitted to the pediatric department, ramathibodi hospital during january to december 1977 was studied. a total of 144 medical records (55.6%) could be analysed; rectal swab culture yielded enteropathogenic organisms in 47.2% of the cases consisting of 26.3% salmonella, 16.0% sero typing positive e. coli and 3.5% shigella. clinical presentation of each group was presented which with the exception of neurological symptoms was in co ...1979384546
