Conjugal Transfer of Genetic Information in Group N Streptococci [PDF]
Applied and Environmental Microbiology, 1980 Streptococcus lactis strains ML3 and C 2 O and S. lactis subsp. diacetylactis strains DRC3, 11007, and WM 4 were found to transfer lactose-fermenting ability to LM0230, an S. lactis C2 lactose-negative (Lac

Assembly and transfer of tripartite integrative and conjugative genetic elements [PDF]
Proceedings of the National Academy of Sciences, 2016 Significance Integrative and conjugative elements (ICEs) are one of the most prevalent but least-characterized families of mobile genetic elements in bacteria. We identified a family of ICEs that exists as three separate parts integrated within the single chromosomes of symbiotic mesorhizobia.

Genetic stereo matching using complex conjugate wavelet pyramids [PDF]
Proceedings 2001 International Conference on Image Processing (Cat. No.01CH37205), 2002 A new genetic algorithm-based optimisation technique for stereo matching using complex conjugate wavelet pyramids is proposed. Reliable disparity fields are estimated in the wavelet domain with low computational cost. The new cost function is composed of the differences in wavelet coefficient values, plus vertical discontinuity and ordering constraints.

Genetic Engineering and Chemical Conjugation of Potato Virus X [PDF]
, 2013 Here we report the genetic engineering and chemical modification of potato virus X (PVX) for the presentation of various peptides, proteins, and fluorescent dyes, or other chemical modifiers. Three different ways of genetic engineering are described and by these means, peptides are successfully expressed not only when the foot and mouth disease virus ...

Genetic drift suppresses bacterial conjugation in spatially structured populations [PDF]
Biophysical Journal, 2014 ABSTRACT Conjugation is the primary mechanism of horizontal gene transfer that spreads antibiotic resistance among bacteria. Although conjugation normally occurs in surface-associated growth (e.g., biofilms), it has been traditionally studied in well-mixed liquid cultures lacking spatial structure, which is known to ...

Type IV Coupling Proteins as Potential Targets to Control the Dissemination of Antibiotic Resistance
Frontiers in Molecular Biosciences, 2020 The increase of infections caused by multidrug-resistant bacteria, together with the loss of effectiveness of currently available antibiotics, represents one of the most serious threats to public health worldwide. The loss of human lives and the economic

Development of a high-throughput platform to measure plasmid transfer frequency
Frontiers in Cellular and Infection Microbiology, 2023 Antibiotic resistance represents one of the greatest threats to global health. The spread of antibiotic resistance genes among bacteria occurs mostly through horizontal gene transfer via conjugation mediated by plasmids.

Midbiotics: conjugative plasmids for genetic engineering of natural gut flora [PDF]
Gut Microbes, 2019 The possibility to modify gut bacterial flora has become an important goal, and various approaches are used to achieve desirable communities. However, the genetic engineering of existing microbes in the gut, which are already compatible with the rest of the community and host immune system, has not received much attention.
