Plasmids coding for heat-labile enterotoxin production isolated from Escherichia coli O78: comparison of properties.
Nineteen enterotoxigenic Escherichia coli strains of serogroup O78, isolated in different geographical areas from humans with diarrheal diseases, were tested for their ability to transfer enterotoxin production. All of the strains originally produced heat-labile enterotoxin, and 16 also produced heat-stable enterotoxin and colonization factor antigen I. Plasmids coding for the production of hea...
متن کاملMapping of a plasmid, coding for colonization, factor antigen I and heat-stable enterotoxin production, isolated from an enterotoxigenic strain of Escherichia coli.
The non-autotransferring plasmid NTP113 codes for production of colonization factor antigen I and heat-stable enterotoxin, NTP113, which has a molecular weight of 58 X 10(6), was digested with BamHI, EcoRI, and HindIII and combinations of these restriction endonucleases, and the products of these digestions were analyzed by agarose gel electrophoresis. The results were used to construct a parti...
متن کاملPlasmids coding for colonization factor antigen I and heat-stable enterotoxin production isolated from enterotoxigenic Escherichia coli: comparison of their properties.
We examined seven enterotoxigenic Escherichia coli strains which produced colonization factor antigen I (CFA/I). Four of these strains were from South Africa (three serotype O78:H12 and one serotype O63:H-), one was from Ethiopia (O78:H12), and two were from Bangladesh (O78:H11 and O78:H12). Plasmids coding for CFA/I were mobilized from six of these strains by using resistance or enterotoxin fa...

the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...
