Uptake signal sequences (USS) are short DNA sequences preferentially taken up by competent bacteria of the family Pasteurellaceae (e.g., Haemophilus influenzae). Similar sequences, called DNA uptake sequences (DUS), are found in species of the family Neisseriaceae (including Neisseria meningitidis and Neisseria gonorrhoeae).
