The N-acylneuraminate cytidyltransferase gene, neuA, is heterogenous in Legionella pneumophila strains but can be used as a marker for epidemiological typing in the consensus sequence-based typing scheme.

Abstract excerpt

Sequence-based typing (SBT) is the internationally recognized standard method for genotyping Legionella pneumophila. To date all strains of serogroup 1 (SG1) and some of SGs 2 to 14 yield a seven-allele profile and can be assigned a sequence type (ST). However, for some strains belonging to SGs 2 to 14, the targeted region of the neuA gene could not be amplified using the published standard primers. We determined...
