Abstract: Provided are solid supports that contain at least one hydrophilic ligand; and at least one hydrophobic ligand, where amount of the at least one hydrophobic ligand on the solid support relative to the amount of the at least one hydrophilic ligand on the solid support is adjusted for binding target nucleic acid(s) from a sample onto the solid support and/or for eluting the bound target nucleic acid(s) from the solid support, so that the amount of target nucleic acid(s) bound to the solid support and/or recovered after elution from the solid support is about 5% to about 500% greater than the amount of target nucleic acid(s) bound to the solid support and/or recovered from the solid support in the absence of either the at least one hydrophobic ligand or the at least one hydrophilic ligand or both. The solid supports with ligands are used for isolation of nucleic acid molecules from samples.

Abstract: The invention includes compositions and methods of detection of Bacillus anthracis that use oligonucleotide probes specific for genetic material contained in the pXO1 and pXO2 plasmids in nucleic acid hybridization reactions. Embodiments of the method may include additional probes specific for other gene sequences to distinguish B. anthracis from other bacterial species present in a sample or to provide an indication that the assay was performed properly even when no Bacillus sequence is detected.

Abstract: A method for capturing a target polynucleotide in a sample onto a solid support with an attached immobilized probe by using a capture probe and two different hybridization conditions that control the order of hybridization, where the first hybridization condition allows hybridization of the capture probe to the target polynucleotide, and the second hybridization condition allows hybridization of the capture probe to the immobilized probe. The method further includes amplifying the captured target polynucleotide by hybridizing at least one primer oligonucleotide to the target polynucleotide and using nucleic acid amplification that initiates from the primer oligonucleotide.

Abstract: A method for capturing a target polynucleotide in a sample onto a solid support with an attached immobilized probe by using a capture probe and two different hybridization conditions, which preferably differ in temperature only, is disclosed. The two hybridization conditions control the order of hybridization, where the first hybridization conditions allow hybridization of the capture probe to the target polynucleotide, and the second hybridization conditions allow hybridization of the capture probe to the immobilized probe. The method may be used to detect the presence of a target polynucleotide in a sample by detecting the captured target polynucleotide or amplified target polynucleotide.

Abstract: Nucleic acid sequences which hybridize preferentially to the 16S or 23S rRNA or rDNA of Legionella sp., L. pneumophila, L. micdadei, a L. pneumophila, or a Legionella subset are taught. These organisms are the etiological agents of Legionnaires' disease, Pontiac fever, Pittsburgh pneumonia and other infections. The nucleic acids are useful in the detection of these pathogenic microorganisms. Probes based on these sequences and kits containing the probes are also disclosed.

Abstract: Nucleic acid probes are described for detecting the principle etiological agent of primary atypical pneumonia, Mycoplasma pneumoniae, or, optionally, Mycoplasma pneumoniae and Mycoplasma genitalium. Said probes are complementary to ribonucleic acid sequences found in these mycoplasmas and absent from other mycoplasma, other bacterial, animal, or plant genomes. As such, these probes can detect the rRNA, rDNA, or polymerase chain reaction amplification products from these mycoplasma species. This set of probes, plus the described amplification primers, circumscribe a method for detecting the etiological agents of atypical pneumonia, and for making a clinical diagnosis of this disease. This set of probes also circumscribes a method for identification of these infectious agents in culture media enrichments inoculated from clinical samples.
