Patent ID: 8808996

Claim:
A method for detecting the presence or absence of a serogroup of Legionella pneumophila in a sample, wherein said method comprises detecting the presence or absence of hybridization of nucleic acid of said sample to a specific genetic marker, said marker selected from the group consisting of: a) SEQ ID NO: 1; b) a fragment of SEQ ID NO: 1 comprising at least 50 contiguous nucleotides of SEQ ID NO: 1; c) a homolog of SEQ ID NO: 1 at least 95% identical to SEQ ID NO: 1; and d) a fragment of said homolog comprising at least 50 contiguous nucleotides thereof wherein said fragment is at least 95% identical to SEQ ID NO: 1; wherein the presence of hybridization indicates the presence in the sample of Legionella pneumophila of at least one of serogroups 2-14, and wherein the absence of hybridization indicates the absence in the sample of Legionella pneumophila of serogroups 2-14.
