Haemoproteus tartakovskyi and Plasmodium relictum (Haemosporida, Apicomplexa) differentially express distinct 18S rRNA gene variants in bird hosts and dipteran vectors.

ABSTRACT:

Background

Most mammalian Plasmodium species possess distinct 18S ribosomal RNA (rRNA) gene copies, which are differentially expressed in vertebrate hosts and mosquito vectors. Although similar sequence patterns were found in avian haemosporidian parasites, expression patterns have not been studied yet. This study aimed to test whether 18S variants of Plasmodium relictum SGS1 and Haemoproteus tartakovskyi SISKIN1 are expressed differentially in bird hosts and dipteran vectors using real-time quantitative polymerase chain reaction (qPCR) and chromogenic in situ hybridization (CISH).

Methods

Eurasian siskins (Spinus spinus) experimentally infected with P. relictum SGS1 and naturally infected with H. tartakovskyi SISKIN1 were used. Culex quinquefasciatus mosquitoes (SGS1) and C
