Molecular detection of Megatrypanum trypanosomes in tabanid flies

Trypanosomes of the subgenus Megatrypanum have been isolated from many mammalian hosts around the world. They are usually non‐pathogenic, although they may confuse the parasitological diagnosis of trypanosomosis. Additionally, Trypanosoma theileri has been associated with disease in cattle. Megatryp...

Description
Summary:Trypanosomes of the subgenus Megatrypanum have been isolated from many mammalian hosts around the world. They are usually non‐pathogenic, although they may confuse the parasitological diagnosis of trypanosomosis. Additionally, Trypanosoma theileri has been associated with disease in cattle. Megatrypanum trypanosomes are considered to be transmitted by different arthropods, including tabanids. However, little is known about the potential vectors of Megatrypanum trypanosomes in different parts of the world. The present study reports on the detection of Megatrypanum trypanosomes in Heamatopota pluvialis, Tabanus bromius, Tabanus maculicornis and Tabanus distinguendus in Poland. It also discusses the possible role of these tabanids in the transmission of Megatrypanum trypanosomes. The present study reports the detection of Megatrypanum trypanosomes in Heamatopota pluvialis, Tabanus bromius, Tabanus maculicornis and Tabanus distinguendus in Poland. The overall positivity to Trypanosoma spp. DNA in tabanids was 33.68% (32/95). Nucleotide sequences generated herein were related to Theileria theileri‐like group I (from T. maculicornis and T. distinguendus) and T. theileri‐like group II (from H. pluvialis).
