摘要

Ethanol-fixed entire bodies of the tsetse fly,?Glossina fuscipes fuscipes, and unidentified stable flies,?Stomoxys?spp., collected from near Juba town, southern Sudan, were tested for?Trypanozoon?trypanosomes infections using polymerase chain reaction (PCR) technique for the first time in Sudan. The crude target DNA sequences were extracted by incubation of entire flies in Nonindet PCR template buffer containing proteinase-K. The DNA amplification sets of conditions were adjusted for each pair of primers employed. The oligonucleotide primers used included TBR1-2, SRAA-E, SRAB537-B538?and TgsGPFOR-REV. The results showed that 74.4% of?G. f. fuscipes?and 39.36% of?Stomoxys?spp. were infected withTrypanozoon?trypanosomes. Out of the 117 examined?G. f. fuscipes, 46.2, 24.8, 35.04, 17.09 and 10.26% were due to?T. b. gambiense?(TgsGPFOR-REV),?T. b. rhodesiense?(SRAA-E),?T. b. rhodesiense?(SRA3537-3538), mixed infection with?T. b. gambiense?and?T. b. rhodesiense?and?T. b. brucei,?respectively. However, infections in?Stomoxys?spp. of 2.13 and 37.2% were due to?T. b. rhodesiense?andT. b. brucei, respectively.
