Animal African trypanosomosis (AAT), caused by Trypanosoma congolense, is widespread throughout sub-Saharan Africa. There are significant concerns related to the current drugs available for the treatment of AAT due to their limited effectiveness across species and their adverse effects. Moreover, drug resistant trypanosomes have recently been reported in the field. High throughput screening (HTS) of large chemical compound library collections is a promising approach for identifying novel drug candidates. While HTS for Trypanozoon trypanosomes, T. brucei sspp. and T. evansi is well established, no assays have been developed for T. congolense. In the present study, the authors developed an ATP-based luciferase viability assay for T. congolense in a 96-well... |

Trypanosoma congolense is a major livestock pathogen in Africa, causing large economic losses with serious effects on animal health. Reliable serodiagnostic tests are therefore urgently needed to control T. congolense infection. In this study, we have identified one T. congolense protein as a new candidate serodiagnostic antigen. The 46.4 kDa protein (TcP46, Gene ID: TcIL3000.0.25950) is expressed 5.36 times higher in metacyclic forms than epimastigote forms. The complete nucleotide sequences of TcP46 contained an open reading frame of 1,218 bp. Southern blot analysis indicated that at least two copies of the TcP46 gene were tandemly-arranged in the T. congolense genome. The recombinant TcP46 (rTcP46) was expressed in Escherichia coli as a glutathione... |
