Int J Parasitol . 2024 Apr; 54(8-9):391-400. PMID: 38663543
Nearly all aerobic organisms are equipped with catalases, powerful enzymes scavenging hydrogen peroxide and facilitating defense against harmful reactive oxygen species. In trypanosomatids, this enzyme was not present in the...

Eur J Protistol . 2023 Nov; 91:126029. PMID: 37918183
In this study, we presented the results of our molecular phylogenetic analysis of Archamoebae using a newly obtained sequence of the 18S rRNA gene of Mastigamoeba aspera, the type species...

Macedo D, Grybchuk D, Reznarova J, Votypka J, Klocek D, Yurchenko T, et al.
BMC Biol . 2023 Sep; 21(1):191. PMID: 37697369
Background: Trypanosomatids are parasitic flagellates well known because of some representatives infecting humans, domestic animals, and cultural plants. Many trypanosomatid species bear RNA viruses, which, in the case of human...

Albanaz A, Carrington M, Frolov A, Ganyukova A, Gerasimov E, Kostygov A, et al.
BMC Genomics . 2023 Aug; 24(1):471. PMID: 37605127
Background: Protists of the family Trypanosomatidae (phylum Euglenozoa) have gained notoriety as parasites affecting humans, domestic animals, and agricultural plants. However, the true extent of the group's diversity spreads far...

Kostygov A, Malysheva M, Ganyukova A, Razygraev A, Drachko D, Yurchenko V, et al.
Pathogens . 2022 Nov; 11(11). PMID: 36422578
Monoxenous (insect-restricted) trypanosomatids are highly diverse and abundant in nature. While many papers focus on the taxonomy and distribution of these parasites, studies on their biology are still scarce. In...

Parasit Vectors . 2022 Mar; 15(1):95. PMID: 35313955
Background: Trypanosoma theileri species complex includes parasites of Bovidae (cattle, sheep, goat, etc.) and Cervidae (deer) transmitted mainly by Tabanidae (horse flies and deerflies) and keds (Hippoboscidae). While morphological discrimination...

Trends Parasitol . 2021 Mar; 37(6):538-551. PMID: 33714646
In this review, we summarize the current data on development of monoxenous trypanosomatids and phytomonads in various insects. Of these, Diptera and Hemiptera are the main host groups, and, consequently,...

BMC Biol . 2020 Dec; 18(1):187. PMID: 33267865
Background: The family Trypanosomatidae encompasses parasitic flagellates, some of which cause serious vector-transmitted diseases of humans and domestic animals. However, insect-restricted parasites represent the ancestral and most diverse group within...

Folia Parasitol (Praha) . 2020 May; 67. PMID: 32350156
Here we describe the new trypanosomatid, Phytomonas borealis sp. n., from the midgut of the spiked shieldbugs, Picromerus bidens (Linnaeus), collected in two locations, Novgorod and Pskov Oblasts of Russia....
