Abstract: ?-hemolytic streptococci polynucleotides, polypeptides, particularly Streptococcus pyogenes polypeptides and polynucleotides, and antibodies of these polypeptides are described. The polynucleotides, polypeptides, and antibodies of the invention can be formulated for use as immunogenic compositions. Also disclosed are methods for immunizing against and reducing ?-hemolytic streptococcal infection, and for detecting ?-hemolytic streptococci in a biological sample.

Abstract: The present invention generally relates to the fields of molecular biology, clinical bacteriology and protein folding. More particularly, the invention relates to methods for recombinantly expressing a soluble mature Streptococcus pyogenesexotoxin B (SpeB) polypeptide in a host cell.

Abstract: The present invention provides probe arrays and methods of using the same for concurrent and discriminable detection of multiple strains of different species. In one aspect, the probe arrays of the present invention are nucleic acid arrays comprising (1) a first group of probes, each of which is specific to a different respective strain of a first species; and (2) a second group of probes, each of which is specific to a different respective strain of a second species. In many embodiments, the nucleic acid arrays of the present invention further include a third group of probes, each of which is specific to a different strain of a third species. In one example, a nucleic acid array of the present invention includes probes for sequences selected from SEQ ID NOs: 1 to 18,598, and can discriminably detect different strains of Streptococcus pyogenes, Streptococcus agalactiae and Staphylococcus epidermidis.
