DNA transfer between related bacterial species is enhanced by species-specific uptake
sequences. These sequences have been used to identify genes that have been transferred …

Members of the bacterial families Haemophilus and Neisseria, important human pathogens
that commonly colonize the nasopharynx, are naturally competent for DNA uptake from their …

Uptake signal sequences are DNA motifs that promote DNA uptake by competent bacteria in
the family Pasteurellaceae and the genus Neisseria. The genomes of these bacteria contain …

Cross-transformation and quantitative competition experiments showed that Neisseria
gonorrhoeae and Haemophilus influenzae do not interact with each other's DNA in …

Piliated, competent gonococci are known to preferentially take up homologous transforming
DNA into the cell. We examined the mechanism for DNA uptake with pFA10, a hybrid 11.5 …

Comparison of closely related genome sequences can provide a clue as to how
macroscopic genome polymorphisms were formed through various events of recombination …

We have developed a method for identifying essential genes by using an in vitro
transposition system, with a small (975 bp) insertional element containing an antibiotic …

Bacteria exchange genetic material by three basic mechanisms: conjugation, transduction,
and transformation (Fox, 1978). Conjugation is a plasmidmediated transfer of DNA from …

Repeated sequence signatures are characteristic features of all genomic DNA. We have
made a rigorous search for repeat genomic sequences in the human pathogens Neisseria …
