title: Human serum sensitivities of Trypanozoon isolates from naturally infected hosts in the Luangwa Valley, Zambia.
abstract: Of 235 Trypanozoon stocks isolated from naturally infected hosts in northeastern Zambia and tested by the Blood Incubation Infectivity Test (BIIT), 176 came from man, 37 from wild-caught tsetse, 11 from wild animals and 11 from domestic livestock. Of those from man, 2 gave unexpected, human-serum-sensitive (HSS) reactions on first testing; all 15 stocks from tsetse in the northern area (Kampumbu) were strongly serum-resistant (HSR) while 22 other infections, from tsetse in the southern area (Kakumbi), gave 1 equivocal, 11 positive and 10 negative test responses. HSR Trypanozoon infections were found in a bushbuck, a warthog, in a giraffe (for the first time) and in a "sentinel" goat, used to monitor SS transmission in a small SS endemic village.
