Conjugation-based genetic manipulation of Fusobacterium animalis
Fusobacterium is an oncobacterium associated with colorectal cancer (CRC) development. Despite that F. animalis (Fa) dominates the CRC niche in humans, studies on the pathogenesis of Fusobacterium have been limited by the paucity of genetically tractable

Conjugation-mediated genetic exchange in Legionella pneumophila [PDF]
Genetic exchange mechanisms, to our knowledge, have not been reported for Legionella pneumophila, and consequently, studies on the genetic organization of L. pneumophila have not appeared in the literature. Here, we describe gene transfer mediated by broad host range conjugative plasmids in Legionella spp. Escherichia coli strains carrying plasmids RP1

Ordering the bestiary of genetic elements transmissible by conjugation [PDF]
Phylogenetic reconstruction of three highly conserved proteins involved in bacterial conjugation (relaxase, coupling protein and a type IV secretion system ATPase) allowed the classification of transmissible elements in relaxase MOB families and mating pair formation MPF groups.

Genetic and physiological analysis of conjugation in Streptococcus faecalis [PDF]
In an effort to elucidate the mechanisms of conjugal plasmid transfer in Streptococcus faecalis, a genetic analysis of the sex pheromone-dependent tetracycline resistance plasmid pCF-10 was initiated. Rare transconjugants obtained from short matings with wild-type donors not exposed to sex pheromones were screened for increased donor potential in a ...

Genetic organization of the bacterial conjugative transposon Tn916 [PDF]
Tn916, which encodes resistance to tetracycline, is a 16.4-kilobase conjugative transposon originally identified on the chromosome of Streptococcus faecalis DS16. The transposon has been cloned in Escherichia coli on plasmid vectors, where it expresses tetracycline resistance; it can be reintroduced into S. faecalis via protoplast transformation.

Oligonucleotide-conjugated beads for transdominant genetic experiments [PDF]
Transdominant genetics using expression libraries can identify proteins and peptides that affect cell division. In conjunction with these libraries, oligo-nucleotide-conjugated beads and flow cytometry were used to test a strategy that potentially expands the range of such genetic studies.

Protein conjugation with genetically encoded unnatural amino acids [PDF]
The site-specific incorporation of unnatural amino acids with orthogonal chemical reactivity into proteins enables the synthesis of structurally defined protein conjugates. Amino acids containing ketone, azide, alkyne, alkene, and tetrazine side chains can be genetically encoded in response to nonsense and frameshift codons.

Crosstalk Between Type VI Secretion System and Mobile Genetic Elements
Many bacterial processes require cell-cell contacts. Such are the cases of bacterial conjugation, one of the main horizontal gene transfer mechanisms that physically spreads DNA, and the type VI secretion systems (T6SSs), which deploy antibacterial ...

The Effect of Outer Space and Other Environmental Cues on Bacterial Conjugation
Bacterial conjugation is one of the most abundant horizontal gene transfer (HGT) mechanisms, playing a fundamental role in prokaryote evolution. A better understanding of bacterial conjugation and its cross talk with the environment is needed for a more ...

Background Extended spectrum beta-lactamase (ESBL)-producing enterobacteria pose a major hazard to public health. Due to the possibility of genetic transfer, ESBL genes might spread to pathogenic enterobacterial strains.
