Amphibian trypanosomes were the first ever described trypanosomatids. Nevertheless, their taxonomy remains entangled because of pleomorphism and high prevalence mixed infections. Despite fact that species in this group Europe, virtually none from European anurans was analyzed using modern molecular methods. In study, we explored diversity phylogeny true frogs Europe light microscopy A comparison observed morphotypes with previous descriptions allowed us to reliably identify three Trypanosoma...
In the present work, we investigated molecular mechanisms governing thermal resistance of a monoxenous trypanosomatid Crithidia luciliae thermophila, which reclassified as separate species C. thermophila. We analyzed morphology, growth kinetics, and transcriptomic profiles flagellates cultivated at low (23°C) elevated (34°C) temperature. When maintained high temperature, they grew significantly faster, became shorter, with genes involved in sugar metabolism mitochondrial stress protection...
ABSTRACT Trypanosomatids are among the most extensively studied protists due to their parasitic interactions with insects, vertebrates, and plants. Recently, Blastocrithidia nonstop was found depart from canonical genetic code, all three stop codons reassigned encode amino acids (UAR for glutamate UGA tryptophan), UAA having dual meaning also as a termination signal (glutamate stop). To explore features linked this phenomenon, we analyzed genomes of four Obscuromonas species, latter...
Abstract Trypanosomatids of the genera Angomonas and Strigomonas (subfamily Strigomonadinae) have long been known to contain intracellular beta-proteobacteria, which provide them with many important nutrients such as haem, essential amino acids vitamins. Recently, Kentomonas sorsogonicus , a divergent member Strigomonadinae, has described. Herein, we characterize genome its endosymbiont, Candidatus Kinetoplastibacterium sorsogonicusi. This is completely syntenic those other Ca . spp., but...
The family Trypanosomatidae encompasses parasitic flagellates, some of which cause serious vector-transmitted diseases humans and domestic animals. However, insect-restricted parasites represent the ancestral most diverse group within family. They display a range unusual features their study can provide insights into biology human pathogens. Here we describe Vickermania, new genus fly midgut-dwelling that bear two flagella in contrast to other trypanosomatids, are unambiguously...
Here we described a new trypanosomatid species, Phytomonas lipae, parasitizing the dock bug Coreus marginatus based on axenic culture and in vivo material. Using light electron microscopy characterized development of this flagellate intestine, hemolymph salivary glands its insect host. The intestinal promastigotes lipae do not divide occur only anterior part midgut. From there they pass into hemolymph, increasing size, then to glands, where actively proliferate without attachment host's...
Here we describe the new trypanosomatid, Phytomonas borealis sp.n., from midgut of spiked shieldbugs, Picromerus bidens (Linnaeus), collected in two locations, Novgorod and Pskov Oblasts Russia.The phylogenetic analyses, based on 18S rRNA gene, demonstrated that this flagellate is a sister species to secondary monoxenous nordicus Frolov et Malysheva, 1993, which was concurrently documented same host Oblast.Unlike P. nordicus, can complete its development (including exit haemolymph...
Here we characterized the development of trypanosomatid Blastocrithidia raabei in dock bug Coreus marginatus using light and electron microscopy. This parasite has been previously reported to occur host hemolymph, which is rather typical for dixenous trypanosomatids transmitted a plant or vertebrate with insect's saliva. In addition, C. an unusual organization intestine, makes it refractory microbial infections: two impassable segments isolate anterior midgut portion responsible digestion...
A new species of Pogonophryne sarmentifera sp. nov. from the Ross Sea (Southern Ocean) is described. The belongs to «mentella» group genus and characterized by having a mental barbel long (68.0–70.0% head length), sarment-shaped with slender terminal expansion (5.9–8.1% length) composed rows short flattened incubous processes; сanals seismosensory system top have small pores; weakly developed internasal organ, peritoneum light.
The article provides a brief biography of the ichthyologist Dmitry Nikolayevich Taliev (1908–1952), as well information and illustrations for 24 taxa described by him from White Sea (Gadidae – one subspecies), coast Okhotsk (Salmonidae Lake Baikal (Cottidae 2 species 4 subspecies; Abyssocottidae 6 8 Baunt 1 species). For 19 taxa, photographs radiographs type specimens kept in collection Zoological Institute Russian Academy Sciences (Saint Petersburg, Russia) are presented first time. Type...
