Purified and isolated nucleic acid molecules are provided which encode Tbp2 proteins ofstrains M35, 3 and LES1. The nucleic acid sequence may be used to produce recombinant Tbp2 proteins of the strain offree of other proteins of thestrain for purposes of diagnostics and medical treatment. Furthermore, the nucleic acid molecules may be used in the diagnosis of infection.

Purified and isolated nucleic acid molecules are provided which encode transferrin receptor proteins of Moraxella, such as or a fragment or an analog of the transferrin receptor protein. The nucleic acid sequence may be used to produce recombinant transferrin receptor proteins Tbp1 and Tbp2 of the strain of Moraxella free of other proteins of the Moraxella strain for purposes of diagnostics and medical treatment. Furthermore, the nucleic acid molecule may be used in the diagnosis of infection.

Transferrin receptor genes of Moraxella

Transferrin receptor of moraxella

An isolated and purified non-denatured transferrin receptor protein of a Moraxella strain, particularly,, has an apparent molecular mass of about 80 to about 90 kDa, as determined by SDS-PAGE. The transferrin receptor protein or a fragment analog thereof is useful in diagnostic applications and immunogenic compositions, particularly for in vivo administration to a host to confer protection against disease caused by a strain of Moraxella.

The transferrin receptor protein or a fragment analog thereof is useful in diagnostic applications and immunogenic compositions, particularly for in vivo administration to a host to confer protection against disease caused by a strain of Moraxella. The transferrin receptor protein is isolated from strains of,by a procedure including extraction of agent soluble proteins of a cell mass produced by cultivating the strain under iron-starved conditions. The transferrin receptor protein is selectively solubilized from the extracted cell mass and purified.

Transferrin receptor protein of moraxella

An isolated and purified non-denatured outer membrane protein CD which is that of or corresponds to that isolatable from a Branhamella strain, particularly B. catarrhalis, is isolated from a bacterial strain by fractionating a cell lysate formed by disrupting a cell mass of the bacterial strain by centrifugation to provide a pellet and a discard supernatant containing a large proportion of soluble bacterial proteins. The pellet is selectively extracted to remove the remaining soluble proteins, the membrane proteins other than CD and other contaminants such as lipopolysaccharide and phospholipids. The remaining CD-containing pellet is dispersed and solubilized and then fractionated by centrifugation to remove the remaining cell debris. The CD protein is useful in diagnostic applications and immunogenic compositions, particularly for in vivo administration to a host to confer protection against disease caused by a bacterial pathogen that produces CD protein or produces a protein capable of inducing antibodies in a host specifically reactive with CD protein.

Major outer membrane protein CD of branhamella

Purified and isolated nucleic acid molecules are provided which encode transferrin receptor proteins of Moraxella, such as M. catarrhalis or a fragment or an analog of the transferrin receptor protein. The nucleic acid sequence may be used to produce recombinant transferrin receptor proteins Tbp1 and Tbp2 of the strain of Moraxella free of other proteins of the Moraxella strain for purposes of diagnostics and medical treatment. Furthermore, the nucleic acid molecule may be used in the diagnosis of infection.
