The role of mannose sensitive and mannose resistant pili of Escherichia coli in urinary tract infection
In order to study the relationship between hrmolysin / ashesins of Escherichia coli and occurrence of urinary tract infection ( UTI), the capacity of 570 isolated E.coli in agglutination of human or guinea pig erythrocytes and their lysis were tested. These isolates were obtained from the urine of patients with bacteriuria and from the stool of healthy people. Three patterns of hemagglutinat...
متن کاملThe gntP gene of Escherichia coli involved in gluconate uptake.
The gntP gene, located between the fim and uxu loci in Escherichia coli K-12, has been cloned and characterized. Nucleotide sequencing of a region encompassing the gntP gene revealed an open reading frame of 447 codons with significant homology to the Bacillus subtilis gluconate permease. Northern (RNA) blotting indicated that the gntP gene was monocistronic and was transcribed as an mRNA with ...

15 صفحه اولGenetic analysis of the histidine operon in Escherichia coli K12.
I N Salmonella typhimurium a cluster of nine genes, behaving as a single operon (AMES and GARRY 1959) specify the enzymes which carry out the ten reactions involved in the biosynthesis of histidine; one of the nine enzymes is bifunctional (LOPER, GRABNAR, STAHL, HARTMAN and HARTMAN 1964). The histidine operon is contained in a linear segment of deoxyribonucleic acid (DNA) estimated by AMES, GOL...
متن کاملCharacterization of the cyn operon in Escherichia coli K12.
Escherichia coli can overcome the toxicity of environmental cyanate by hydrolysis of cyanate to ammonia and bicarbonate. This reaction is catalyzed by the enzyme cyanase, encoded by the cynS gene. The nucleotide sequence of cynS has been reported (Sung, Y.-c., Anderson, P. M., and Fuchs, J. A. (1987) J. Bacteriol. 169, 5224-5230). The nucleotide sequence of the complete cyn operon has now been ...
