Haemoproteus parasites are the most diverse among Haemosporida. However, their natural vectors (Culicoides) still poorly investigated and were identified for only a few parasite species lineages. The application of an integrative approach (insect dissection, microscopic analysis, molecular-based methods) is necessary in these studies, which have been carried out by research groups, mainly Europe. aim this study was (i) to determine Culicoides that naturally infected parasites, can support...
Haemoproteus blood parasites of birds are thought to be relatively benign. Recent findings show that infections may develop in the brain birds, possibly distorting their orientation sense. Misdirected migration lead migrants outside range where they recognized as vagrants and can transmit novel hosts.
Leucocytozoon species are cosmopolitan and prevalent avian parasites, with some infections being lethal, mainly due to the exo-erythrocytic development of parasite in bird tissues. The patterns spp. wild birds remain poorly studied. This study investigated tissue stages tits (Paridae). Great ( Parus major ), Blue Cyanistes caeruleus Coal Periparus ater ) were screened for using an integrative approach that consisted microscopic analysis thin blood smears, histological techniques, chromogenic...
Viruses are diverse biological entities found virtually in all environments on Earth. Their association with parasitic protozoans was shown the late 1980's, followed by evidence that these viruses can influence treatment of infections as well parasite virulence. Recently, Matryoshka RNA (MaRNAV) were discovered Plasmodium vivax infected patients Malaysia, species closely related avian haemosporidian genera Leucocytozoon and Haemoproteus Oceania North America. However, they have not been...
Avian haemosporidians are widespread parasites categorized into four families of the order Haemosporida (Apicomplexa). Species subgenus Parahaemoproteus (genus Haemoproteus) belong to Haemoproteidae and transmitted by Culicoides biting midges. Reports death due tissue damage during haemoproteosis in non-adapted birds have raised concerns about these pathogens, especially as their exo-erythrocytic development is known for only a few Haemoproteus spp. More research needed better understand...
Cervical cancer is a public health concern as it represents the second cause of death in women worldwide. High-risk human papillomaviruses (HPV) are etiologic agents, and HPV E6 and/or E7 oncogene-specific therapeutic vaccines under development to treat HPV-related lesions women. Whether use mucosal routes immunization may be preferable for inducing cell-mediated immune responses able eradicate genital tumors still debated because uniqueness female mucosa (GM) limited experimentation. Here,...
Haemoproteus (Parahaemoproteus) parasites are transmitted by Culicoides biting midges. However, the natural vectors of only six almost 180 recognized species have been identified. The aim this study was to investigate wild midges naturally infected with and understand interaction network between in Europe. were collected UV light traps from different sites Lithuania. Parous females morphologically identified based on their wings heads. PCR-based methods used detect DNA, salivary gland...
parasites (Apicomplexa, Haemosporida) are widespread pathogens of birds, with a rich genetic (about 1900 lineages) and morphospecies (178 species) diversity. Nonetheless, their life cycles poorly understood. The exo-erythrocytic stages three
Species of Haemoproteus (Haemoproteidae, Haemosporida) are common bird pathogens. Recent molecular studies combined with histopathology research have reported development megalomeronts these parasites in various organs, sometimes resulting the death avian host. Five Common starlings (Sturnus vulgaris) were found naturally infected pastoris lineage hLAMPUR01. The parasite was identified using microscopic examination blood films and DNA sequences. Infected organs investigated histologically...
Haemoproteus species are widespread avian blood parasites belonging to Haemoproteidae (Haemosporida). Blood stages of these pathogens have been relatively well-investigated, though exo-erythrocytic (tissue) remain unidentified for the majority species. However, recent histopathological studies show that haemoproteins markedly affect bird organs during tissue merogony. This study investigated development (Parahaemoproteus) attenuatus (lineage hROBIN1), common parasite flycatchers...
Investigations of host feeding behaviour in haematophagous insects are critical to assess transmission routes vector-borne diseases. Understanding if a certain species has ornithophilic or mammalophilic can facilitate future studies focused on pathogens and from species. Culicoides Latreille (Diptera: Ceratopogonidae) vectors several pathogens, which include arboviruses, bacteria parasites considerable diversity vertebrate hosts. However, most the habits target that could transmit Bluetongue...
Leucocytozoon parasites remain poorly investigated in comparison to other haemosporidians. The host cell inhabited by their blood stages (gametocytes) remains insufficiently known. This study aimed determine the cells gametocytes different species of Passeriformes and test if this feature has a phylogenetic importance. We microscopically analyzed films stained with Giemsa from six bird individuals used PCR-based methods for parasite lineage identification. DNA sequences obtained were applied...
Malaria is a health problem not only in human and veterinary medicine, but also wildlife. Several theoretical studies have suggested that avian malaria transmission might be increasing Europe. However, there are few direct empirical observations. Research on the distribution of haemosporidian parasites was initiated around Curonian Lagoon, Europe 1976 continues since. This has provided an opportunity to compare prevalence diversity (genus Plasmodium) related haemosporidians (genera...
Abstract Background Sequencing parasite genomes in the presence of host DNA is challenging. Sequence capture can overcome this problem by using RNA probes that hybridize with and then are removed from solution, thus isolating for efficient sequencing. Methods Here we describe a set sequence designed to target 1035 genes (c. 2.5 Mbp) globally distributed avian haemosporidian parasite, Plasmodium relictum . Previous studies haemosporidians genus Haemoproteus have shown sequencing success...
The Wildlife Malaria Network (WIMANET) is a groundbreaking multinational collaboration focused on studying vector-borne haemosporidian parasites in wildlife. Unlike human malaria, wildlife malaria found all continents except Antarctica, with being transmitted by range of vectors. complexity and diversity these makes it necessary to have an interdisciplinary approach understand mitigate their impacts. Established 2023 within the framework COST-Action (European Cooperation Science Technology),...
Abstract Background Although avian Plasmodium species are widespread and common across the globe, limited data exist on how genetically variable their populations are. Here, hypothesis that blood parasite relictum exhibits very low genetic diversity in its Western Palearctic transmission area (from Morocco to Sweden north Transcaucasia east) was tested. Methods The of investigated by sequencing a portion (block 14) fast-evolving merozoite surface protein 1 (MSP1) gene 75 different P....
