The β-lactamase genes of Haemophilus influenzae are commonly positioned on large integrative and conjugative elements, but a group of blaTEM-carrying small plasmids (4000-6000 bp) with a common structural backbone have recently been characterized. In this study we investigated the epidemiological significance and potential for transfer of this group of small plasmids.

Plasmids play essential roles in bacterial metabolism, evolution, and pathogenesis. The maintenance of plasmids is of great importance both scientifically and practically. In this mini-review, I look ...
In this study, five classes of antibiotic resistance genes (ARGs) were quantified in sediment samples of Haihe River, China, with abundance ranging from 1.39 × 10(4) to 1.58 × 10(10) copies/g dr...
Bacteria frequently carry mobile genetic elements capable of being passed to other bacterial cells. An example of this is the transfer of plasmids (small, circular DNA molecules) that often contain an...
Conjugation is a dominant mechanism of horizontal gene transfer and substantially contributes to the plasticity and evolvability of prokaryotic genomes. The impact of conjugation on genetic flux exten...
Plasmids are thought to play a key role in bacterial evolution by acting as vehicles for horizontal gene transfer, but the role of plasmids as catalysts of gene evolution remains unexplored. We challe...
EGAST 2008 is a prospective, non interventional, multicentric study (approximately 2000 isolates from 15- 20 sites). Objectives: - Comparison of antimicrobial susceptibility usi...
This is a randomized cross-sectional study of the Swedish population. Blood samples will be collected from a subpopulation in order to estimate the age specific sero-prevalence of the Swed...
DNA vaccines consist of small pieces of DNA also known as plasmids, and have several potential advantages over traditional vaccines. Thus far, DNA vaccines appear to be well tolerated in h...
DNA vaccines, which are small pieces of DNA also known as plasmids, have several advantages over traditional vaccines such as live attenuated virus and recombinant protein-based vaccines. ...
In this study, the investigators evaluated a therapeutic HIV-1 DNA vaccine administered with a novel topical application method to 12 chronically HIV-infected cART treated patients. The HI...
The probability distribution associated with two mutually exclusive outcomes; used to model cumulative incidence rates and prevalence rates. The Bernoulli distribution is a special case of binomial distribution.
A class of plasmids that transfer antibiotic resistance from one bacterium to another by conjugation.
Plasmids encoding bacterial exotoxins (BACTERIOCINS).
Enzymes that transfer the ADP-RIBOSE group of NAD or NADP to proteins or other small molecules. Transfer of ADP-ribose to water (i.e., hydrolysis) is catalyzed by the NADASES. The mono(ADP-ribose)transferases transfer a single ADP-ribose. POLY(ADP-RIBOSE) POLYMERASES transfer multiple units of ADP-ribose to protein targets, building POLY ADENOSINE DIPHOSPHATE RIBOSE in linear or branched chains.
Clavulanic acid and its salts and esters. The acid is a suicide inhibitor of bacterial beta-lactamase enzymes from Streptomyces clavuligerus. Administered alone, it has only weak antibacterial activity against most organisms, but given in combination with beta-lactam antibiotics prevents antibiotic inactivation by microbial lactamase.
