The first RNA viruses detected in a trypanosome: novel narnaviruses and a leishmaniavirus in the gecko parasite Trypanosoma platydactyli

Alexei Yu. Kostygov, Danyil Grybchuk, Donnamae Klocek…·Vyacheslav Yurchenko

The paper identifies and characterizes the first RNA viruses in trypanosomes, including a leishmaniavirus and two narnaviruses in Trypanosoma platydactyli, suggesting ecological factors influence viral acquisition.

Genomic evidence for phylogenetic congruence with sporadic host shifts in leishmaniaviruses and their parasite hosts

Senne Heeren, Lilian Motta Cantanhêde, Khaled Chourabi…·Elisa Cupolillo

This study investigates the co-phylogenetic history of Leishmania parasites and Leishmaniavirus, finding strong phylogenetic congruence at the subgenus and species level, with weaker signals in some cases due to intraspecific host switching.
