Field evaluation of a dot-ELISA for the detection and differentiation of trypanosome species in infected tsetse flies (Glossina spp.).

abstract：:Endotoxaemia has been described in cases of Human African trypanosomiasis (HAT), but it is unclear if this phenomenon influences inflammatory pathology either in the periphery or central nervous system (CNS). We studied endotoxin concentrations in the plasma and cerebrospinal fluid (CSF) of Trypanosoma brucei rhodesie...
