A 2760-base pair DNA segment of the Pseudomonas aeruginosa strain PA103 chromosome
encoding the exotoxin A (ETA) structural gene has been cloned in Escherichia coli and the …

Protein toxins are key molecular weapons in biology that are used to attack neighboring
cells. Bacteria use protein toxins to kill or inhibit the growth of prokaryotic and eukaryotic …

Shiga toxin-converting bacteriophages (Stx phages) are involved in the pathogenicity of
some enteric bacteria, such as Escherichia coli O157: H7. Stx phages are released from …

Lysogenic bacteriophages are major vehicles for the transfer of genetic information between
bacteria, including pathogenicity and/or virulence determinants. In the enteric pathogen …

Radiolabeled bacteriophage DNA probes have been used in this study to determine the
distribution of Pseudomonas aeruginosa-infecting bacteriophages in natural samples of lake …

Oligonucleotide probes constructed from the sequences published for Shiga-like toxin I (SLT-
I) and Shiga-like toxin II (SLT-II) genes and antibody against the purified toxins were used to …

Shiga-like toxin (SLT-II) was purified to apparent homogeneity from Escherichia coli K-12
strain NM522 containing the cloned toxin genes on recombinant plasmid pEB1. Purification …

Escherichia coli isolated from 2,126 children in Thailand and the Philippines was examined
for enterotoxin production and for DNA hybridization with synthetic oligonucleotide and …

Shiga toxin (Stx)-producing Escherichia coli (STEC) strains isolated from a seagull in Japan
were examined. A total of 50 faecal samples was collected on a harbour bank in Hokkaido …
