Abstract
The present invention provides methods for predicting the likelihood of mortality from melioidosis and detecting the presence of Burkholderia pseudomallei in a test sample.
Claims11
A method for predicting likelihood of mortality from melioidosis, comprising
- (a) analyzing a test sample from a subject suffering from melioidosis for presence or absence of:
- i) ten or more contiguous nucleotides of a YLFC nucleotide sequence according to nucleotides 153167-158624 of GenBank accession number NC—006351 or complements thereof, and/or
- ii) ten or more contiguous nucleotides of a BTFC gene cluster nucleotide sequence according to GenBank accession number EF377328;
- and
- (b) correlating a presence of the ten or more contiguous nucleotides of the BTFC gene cluster, or complements thereof, with a decreased likelihood of subject mortality from melioidosis;
- and/or;
- (c) correlating a presence of the ten or more contiguous nucleotides of the YLFC with an increased likelihood of subject mortality from melioidosis.
A method for detecting the presence of Burkholderia. pseudomallei in a sample, comprising
- (a) analyzing a test sample from a subject suspected of suffering from a Burkholderia infection for the presence or absence of:
- i) ten or more contiguous nucleotides of a Yersinia-like fimbriae cluster (YLFC) nucleotide sequence according to nucleotides 153167-158624 of GenBank accession number NC—006351 or complements thereof, and/or
- ii) ten or more contiguous nucleotides of a Burkholderia thailandensis-like flagella and chemotaxis (BTFC) gene cluster nucleotide sequence according to GenBank accession number EF377328;
- and
- (b) correlating a presence of the ten or more contiguous nucleotides of the BTFC gene cluster, or complements thereof, or the ten or more contiguous nucleotides of the YLFC with the presence of Burkholderia pseudomallei in the test sample.
A method for predicting likelihood of mortality from melioidosis, comprising
- (a) analyzing a test sample from a subject suffering from melioidosis for presence or absence of:
- i) one or more YLFC polypeptides as set forth in any of SEQ ID NOs:
- 56-59, or antigenic fragments thereof
- ii) one or more BTFC polypeptides as set forth in any of SEQ ID NOs:
- 1-55, or antigenic fragments thereof
- (b) correlating a presence of the one or more YLFC polypeptides with an increased likelihood of subject mortality from melioidosis;
- and/or;
- (c) correlating a presence of the one or more BTFC polypeptides with a decreased likelihood of subject mortality from melioidosis.
A method for detecting the presence of Burkholderia. pseudomallei in a sample, comprising
- (a) analyzing a test sample from a subject suspected of suffering from a Burkholderia infection for the presence or absence of:
- i) one or more YLFC polypeptides as set forth in any of SEQ ID NOs:
- 56-59, or antigenic fragments thereof, and/or
- ii) one or more BTFC polypeptides as set forth in any of SEQ ID NOs:
- 1-55, or antigenic fragments thereof;
- and
- (b) correlating a presence of the one or more YLFC polypeptides, or the one or more BTFC polypeptides with the presence of Burkholderia pseudomallei in the test sample.
