## Abstract

A method of protecting an animal from infections with pathogens originating from Yersinia comprising administering an isolated or recombinant YscF protein to the animal is disclosed. The isolated or recombinant YscF protein may be administered as a vaccine. An isolated or recombinant YscF protein capable of conferring protection to an animal against a pathogen of a Yersinia origin is further disclosed. Nucleic acid molecules encoding the isolated or recombinant YscF protein are also disclosed. In other embodiments, antibodies generated against the isolated or recombinant YscF protein capable of conferring protection to an animal against a pathogen or a Yersinia origin and uses of the antibodies are described.

## Claims

### Claim 1

An immunogenic composition comprising:
a means for providing protection to an animal against a pathogen of Yersinia origin, the means for providing protection comprising an isolated or recombinant YscF protein comprising SEQ ID NO: 19; and
a pharmaceutically suitable excipient, wherein the protection may be assayed in a mouse challenge model.

### Claim 2 (depends on 1)

The immunogenic composition of claim 1, further comprising LcrV, the F1 antigen, YopD, an attenuated Yersinia bacterium, a recombinant carrier bacterium including a nucleic acid encoding a YscF protein, an inactive or killed Yersinia bacterium or combinations thereof.

### Claim 3 (depends on 1)

The immunogenic composition of claim 1, further comprising an adjuvant.

The immunogenic composition of claim 1, wherein the means for providing protection to an animal against a pathogen of Yersinia origin is a His-tagged YscF protein.

### Claim 7

An immunogenic composition for providing protection to an animal against a pathogen of Yersinia origin comprising:
a recombinant YscF protein comprising SEQ ID NO: 19; and
a pharmaceutically suitable excipient, wherein the protection may be assayed in a mouse challenge model.

### Claim 8 (depends on 7)

The immunogenic composition of claim 7, further comprising LcrV, the F1 antigen, YopD, an attenuated Yersinia bacterium, a recombinant carrier bacterium including a nucleic acid encoding a YscF protein, an inactive or killed Yersinia bacterium or combinations thereof.

### Claim 9 (depends on 7)

The immunogenic composition of claim 7, further comprising an adjuvant.

### Claim 10 (depends on 7)

The composition produced by the process of claim 12, further comprising mixing PrgI, MxiH, EscF or combinations thereof with the suitable excipient.

### Claim 16

A composition comprising: an isolated or recombinant YscF protein capable of providing protection to an animal against a pathogen of Yersinia origin, the isolated or recombinant YscF protein comprising SEQ ID NO: 19, wherein the protection may be assayed in a mouse challenge model; and
a pharmaceutically acceptable excipient.

### Claim 17 (depends on 1)

The immunogenic composition of claim 1, wherein the pathogen is selected from the group consisting of Y. pestis, Y. pseudotuberculosis, and Y. enterocolitica.

### Claim 18
