Tritrichomonas foetus (T. foetus) is a flagellated protozoan parasite that is recognized as a significant cause of diarrhea in domestic cats with a prevalence rate as high as 30%. No drugs have been shown to consistently eliminate T. foetus infection in all cats. Cysteine proteases (CPs) have been identified as mediators of T. foetus-induced adhesion-dependent cytotoxicity to the intestinal epithelium. These CPs represent novel targets for the treatment of feline trichomonosis. However, cats also produce CPs that are part of life-critical systems. Thus, parasitic CPs need to be selectively targeted to reduce the potential for host toxicity. Previous studies have demonstrated the importance of a specific CP, CP30, in mediating bovine and human trichomonad cytopathogenicity. This CP has also recently been identified in feline T. foetus, although the function of this protease in the feline genotype remains unknown. Furthermore, the study objectives were to characterize the presence of CP30 in feline T. foetus isolates and to evaluate the effect of targeted inhibition of CP30 on feline T. foetus-induced adhesion dependent cytotoxicity.
