Hepatocellular carcinoma (HCC) is the fourth most common cause of cancer-related death in the world, and curative systemic therapies are lacking. Chimeric antigen receptor (CAR)-expressing T cells induce robust antitumor responses in patients with hematologic malignancies but have limited efficacy in patients with solid tumors, including HCC. IL15 and IL21 promote T-cell expansion, survival, and function and can improve the antitumor properties of T cells.

While has been the predominant pathogen of pneumonia in ruminants, is emerging as an important pathogen of ruminant pneumonia. Leukotoxin is the critical virulence factor of these two pathogens.

Bighorn sheep (BHS, Ovis canadensis) are highly susceptible to M. haemolytica-caused pneumonia which has significantly contributed to the drastic decline of bighorn sheep population in North America.

Similar to M. haemolytica , F.

However, Bibersteinia trehalosi and Pasteurella multocida have been isolated from pneumonic bighorn lung tissues more frequently than M. haemolytica by culture-based methods.

Classical bacteriological methods for their identification are cumbersome, time consuming and of potential risk to the handler.
Methods: We describe a sensitive and specific multiplex polymerase chain reaction (mPCR) assay involving novel primers sets for the simultaneous detection of B.
