Evaluation of surface antigen TF1.17 in feline Tritrichomonas foetus isolates.

Tritrichomonas foetus (T. foetus) is a flagellated protozoa that infects the distal ileum and proximal colon of domestic cats, as well as the urogenital tract of cattle. Feline trichomonosis is recognized as a prevalent cause of chronic diarrhea in cats worldwide.

Development of a bead-agglutination assay for rapid detection of Tritrichomonas foetus.

Tritrichomonas foetus is a flagellated protozoan parasite that causes inflammation of the reproductive tract leading to early embryonic death and abortion in cattle, thereby resulting in significant economic losses. Testing and culling infected bulls is an important strategy for parasite control. Routine testing is mainly limited to bulls that are traveling across state lines or within states that have specific control programs.

Expression of Histophilus somni IbpA DR2 protective antigen in the diatom Thalassiosira pseudonana.

Increasing demand for the low-cost production of valuable proteins has stimulated development of novel expression systems. Many challenges faced by existing technology may be overcome by using unicellular microalgae as an expression platform due to their ability to be cultivated rapidly, inexpensively, and in large scale. Diatoms are a particularly productive type of unicellular algae showing promise as production organisms.

A recombinant subunit vaccine for bovine RSV and Histophilus somni protects calves against dual pathogen challenge.

Bovine respiratory syncytial virus (BRSV) and Histophilus somni synergize to cause respiratory disease in cattle. These pathogens cause enhanced disease during dual-infection and an IgE response to antigens of H. somni in dual-infected but not singly infected calves.
