| Research Abstract |
Serological diagnosis is a useful method to detect African trypanosome infection. Currently available serological tests utilize whole parasites or crude antigens. Recombinant antigens may not only enhance test specificity by allowing the detection of species-specific antibodies, but could also improve reproducibility/standardization and reduce production costs. With a goal of identifying such recombinant proteins, we computationally identified proteins with tandem repeat (TR) domain from the parasite proteomes, expressed them and evaluated their potential for serological diagnosis of African trypanosome infections in cattle. Among those tested, Tbg4 demonstrated the best performance with 89% sensitivity and 100% specificity. Our data indicate the potential of these defined antigens for detection of animal African trypanosomiasis.
