The ORF1 gene located on the class-1-integron-associated gene cassette actually represents a novel fosfomycin resistance determinant.
The class 1 integrons are genetic elements capable of integrating gene cassettes by a site-specific recombination mechanism (1). Gene cassettes are mobile units composed of a gene, most often an antibiotic resistance gene, and a recombination site, the 59-base element (1). We have previously characterized a class 1 integron containing a VIM-2-type metallo-lactamase gene, blaVIM-2, an aacA4 gene...
متن کاملNovel streptomycin and spectinomycin resistance gene as a gene cassette within a class 1 integron isolated from Escherichia coli.
The aadA genes, encoding resistance to streptomycin and spectinomycin, have been found as gene cassettes in different gram-negative and gram-positive bacterial species. The present study has revealed the sequence of a new gene, aadA5, integrated as a gene cassette together with the trimethoprim resistance gene dfr7 in a class 1 integron. The integron was located on a plasmid and was identified ...
متن کاملNew trimethoprim-resistant dihydrofolate reductase cassette, dfrXV, inserted in a class 1 integron.
The nucleotide sequence of a plasmid-borne trimethoprim resistance gene from a commensal fecal Escherichia coli isolate revealed a new dihydrofolate reductase gene, dfrXV, which occurred as a gene cassette integrated in a site-specific manner in a class 1 integron. The new gene shows 84% nucleotide identity and the predicted protein shows 90% amino acid identity with dfrI and DHFR type I, respe...
متن کاملlinG, a new integron-associated gene cassette encoding a lincosamide nucleotidyltransferase.
Lincosamide antibiotics include lincomycin, a compound produced by several actinomycetes, and its semisynthetic chlorinated derivative clindamycin. These antibiotics block the peptidyltransferase activity of the 50S subunit of the bacterial ribosome, inhibiting protein synthesis, and are active against most grampositive cocci and anaerobes. However, they are not generally effective against gram...
متن کاملNew integron-associated gene cassette encoding a 3-N-aminoglycoside acetyltransferase.
A fifth gene cassette containing an aacC gene, aacCA5, was found in an aacCA5-aadA7 cassette array in a class 1 integron isolated from a multiply drug resistant Salmonella enterica serovar Kentucky strain. The AacC-A5 or AAC(3)-Ie acetyltransferase encoded by aacCA5 is related to other AAC(3)-I enzymes and confers resistance to gentamicin.
