Genetic Diversity, Biochemical Properties, and Detection Methods of Minor Carbapenemases in Enterobacterales

Frontiers in Medicine, 2021
Gram-negative bacteria, especially Enterobacterales, have emerged as major players in antimicrobial resistance worldwide. Resistance may affect all major classes of anti-gram-negative agents, becoming multidrug resistant or even pan-drug resistant ...

Effect of Subinhibitory Concentrations of Antibiotics and Disinfectants on ISAba-Mediated Inactivation of Lipooligosaccharide Biosynthesis Genes in Acinetobacter baumannii

Antibiotics, 2021
Inactivation of the lipooligosaccharide (LOS) biosynthesis genes lpxA, lpxC and lpxD by ISAba insertion elements results in high-level resistance to colistin in A. baumannii.

Insertion sequences in prokaryotic genomes [PDF]

Current Opinion in Microbiology, 2006
Insertion sequences (ISs) are small DNA segments that are often capable of moving neighbouring genes. Over 1500 different ISs have been identified to date. They can have large and spectacular effects in shaping and reshuffling the bacterial genome. Recent studies have provided dramatic examples of such IS activity, including massive IS expansion during

Polyclonal spread of blaOXA-23 and blaOXA-58 in Acinetobacter baumannii isolates from Argentina

Journal of Infection in Developing Countries, 2008
Background: In order to study the enzymatic carbapenem resistance mechanisms in Acinetobacter baumannii isolates from Argentina, we performed molecular characterization on 41 epidemiologically unrelated strains isolated from 1995 to 2006 with diminished ...

IS481EU Shows a New Connection between Eukaryotic and Prokaryotic DNA Transposons

Biology, 2023
DDD/E transposase gene is the most abundant gene in nature and many DNA transposons in all three domains of life use it for their transposition. A substantial number of eukaryotic DNA transposons show similarity to prokaryotic insertion sequences (ISs ...

Insertion Sequence Diversity in Archaea [PDF]

Microbiology and Molecular Biology Reviews, 2007
SUMMARYInsertion sequences (ISs) can constitute an important component of prokaryotic (bacterial and archaeal) genomes. Over 1,500 individual ISs are included at present in the ISfinder database (www-is.biotoul.fr), and these represent only a small portion of those in the available prokaryotic genome sequences and those that are being discovered in ...

Genomic Characterization of mcr-1.1-Producing Escherichia coli Recovered From Human Infections in São Paulo, Brazil

Frontiers in Microbiology, 2021
Polymyxins are one of most important antibiotics available for multidrug-resistant Gram-negative infections. Diverse chromosomal resistance mechanisms have been described, but the polymyxin resistance phenotype is not yet completely understood.

Everyman's Guide to Bacterial Insertion Sequences [PDF]

Microbiology Spectrum, 2015
ABSTRACT The number and diversity of known prokaryotic insertion sequences (IS) have increased enormously since their discovery in the late 1960s. At present the sequences of more than 4000 different IS have been deposited in the specialized ISfinder database. Over time it has become increasingly apparent that they are important actors in the

Insertion Sequence IS 900 Revisited [PDF]

Journal of Clinical Microbiology, 2006
ABSTRACT Many studies investigating Mycobacterium avium subsp. paratuberculosis in Crohn's disease have used molecular detection of IS 900 in clinical samples, but some have described polymorphisms in IS 900 as variants of this ...

A Novel Widespread MITE Element in the Repeat-Rich Genome of the Cardinium Endosymbiont of the Spider Oedothorax gibbosus

Microbiology Spectrum, 2022
Free-living bacteria have evolved multiple times to become host-restricted endosymbionts. The transition from a free-living to a host-restricted lifestyle comes with a number of different genomic changes, including a massive loss of genes.
