Insertion sequences (ISs) constitute an important component of most bacterial genomes.
Over 500 individual ISs have been described in the literature to date, and many more are …

An explosion of sequence information, the development of unifying concepts and models,
and the physical description of elements in eucaryotes with striking similarities to those …

Use of the sacB gene (JL Ried and A. Collmer, Gene 57: 239-246, 1987) provides a simple,
effective, positive selection for double recombinants in Anabaena sp. strain PCC 7120, a …

The DNA fragment containing the acrA locus of the Escherichia coli chromosome has been
cloned by using a complementation test. The nucleotide sequence indicates the presence of …

The entire nucleotide sequence of a 1.7-kilobase embryonic DNA fragment containing five
joining (J) DNA segments for mouse immunoglobulin κ chain gene has been determined …

The entire nucleotide sequence of the kanamycin resistance transposon Tn903 was
determined by analyzing a mini-ColE1 derivative carrying Tn903. Tn903 was 3094 base …

The potential of bacteriophage as an alternative biocontrol agent has recently been revisited
due to the widespread occurrence of antibiotic-resistant bacteria. We isolated a virulent …

Objectives: A Salmonella enterica serovar Infantis isolate of avian origin was investigated for
the presence of the gene qnrS, its transferability and its association with other resistance …

The element IS50 encodes all Tn5 functions required for transposition and all regulatory
mechanisms. Bacterial transposon Tn5 encodes two proteins, transposase and the …

Genes encoding the synthesis and transport of aerobactin, a hydroxamate siderophore
associated with increased virulence of enteric bacteria, were mapped within a pathogenicity …
