Species of avian malaria parasites (Plasmodium) are widespread, but their virulence has been insufficiently investigated, particularly in wild birds. During malaria, several cycles tissue merogony occur, and many Plasmodium spp. produce secondary exoerythrocytic meronts (phanerozoites), which induced by merozoites developing erythrocytic meronts. Phanerozoites markedly damage organs, remain investigated the majority described Avian parasite (Giovannolaia) homocircumflexum (lineage pCOLL4) is...
Haemoproteus parasites are widespread, and several species cause diseases both in birds blood-sucking insects. These pathogens transmitted by dipterans belonging to the Ceratopogonidae Hippoboscidae, however certain vector remain unknown for majority of spp. Owls often infected parasites, but experimental studies on vectors these infections lacking. The aim this study was investigate sporogonic development two widespread owls, H. noctuae syrnii experimentally biting midges Culicoides...
Microscopic research has shown that Plasmodium relictum is the most common agent of avian malaria. Recent molecular studies confirmed this conclusion and identified several mtDNA lineages, suggesting existence significant intra-species genetic variation or cryptic speciation. Most lineages have a broad range hosts geographical distribution. Here, rare new lineage P. was reported information about biological characters different pathogen reviewed, issues for future research.The pPHCOL01...
Avian malaria parasites (genus Plasmodium) are cosmopolitan and some species cause severe pathologies or even mortality in birds, yet their virulence remains fragmentally investigated. Understanding mechanisms patterns of during avian Plasmodium infections is crucial as these pathogens can severely affect bird populations the wild captive individuals. The goal this study was to investigate caused by recently discovered parasite homocircumflexum (lineage pCOLL4) four European passeriform...
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...
Abstract Haemosporidian parasites belonging to Haemoproteus cause avian diseases, however, vectors remain unidentified for the majority of described species. We used laboratory-reared biting midges Culicoides nubeculosus determine if sporogonic development three widespread completes in this insect. The were reared and fed on one common blackbird, white wagtail thrush nightingale naturally infected with minutus, motacillae attenuatus, respectively. engorged females dissected order follow...
Abstract Background Haemoproteus parasites (Haemosporida, Haemoproteidae) are cosmopolitan in birds and recent molecular studies indicate enormous genetic diversity of these pathogens, which cause diseases non-adapted avian hosts. However, life-cycles remain unknown for the majority species. Information on their exoerythrocytic development is particularly fragmental controversial. This study aimed to gain new knowledge life-cycle widespread blood parasite majoris . Methods Turdus pilaris...
Abstract Avian haemosporidian parasites are widespread globally and infect numerous wild bird species. However, they have primarily been studied in passerine birds. Accordingly, the prevalence diversity of these birds prey remain understudied. This lack research is due to international protection status many species, their sparse distribution across ecosystems difficulty capture wild. The aim this study was examine two species prey, namely white‐tailed eagle lesser spotted eagle. To achieve...
Plasmodium parasites (Plasmodiidae) cause malaria in many species of terrestrial vertebrates and are transmitted mainly by mosquitoes (Culicidae). Avian is often caused relictum , a cosmopolitan hemosporidian infection. Numerous genetic lineages P. have been described. However, it remains unclear if these can be Culex pipiens form molestus, which widespread but has insufficiently investigated as possible vector avian malaria. The aim this study was to test experimentally 2 common complete...
SUMMARY We examined the effects of Haemoproteus infection on survival and pathology caused in biting midges. Forty-six females Culicoides impunctatus were exposed experimentally by allowing them to feed a naturally infected red-backed shrike with lanii (lineage hRB1, gametocytaemia 5·2%). Seventeen fed an uninfected bird (controls). Dead insects collected, counted used for dissection, histological examination polymerase chain reaction-based testing. Parasites present all midges, but absent...
Species of Plasmodium (Plasmodiidae, Haemosporida) are widespread and cause malaria, which can be severe in avian hosts. Molecular markers essential to detect identify parasites, but still absent for many malaria related haemosporidian species. Here, we provide first molecular characterization matutinum, a common agent malaria. This parasite was isolated from naturally infected thrush nightingale Luscinia luscinia (Muscicapidae). Fragments mitochondrial, apicoplast nuclear genomes were...
Recent studies confirmed that some Hepatozoon-like blood parasites (Apicomplexa) of birds are closely related to the amphibian parasite Lankesterella minima. Little is known about biology these pathogens in birds, including their distribution, life cycles, specificity, vectors, and molecular characterization. Using samples 641 from 16 species, we (i) determined prevalence diversity naturally infected birds; (ii) investigated development kabeeni laboratory-reared mosquitoes, Culex pipiens...
Blood parasites of the genus Haemoproteus Kruse, 1890 are cosmopolitan, might be responsible for mortality in non-adapted birds, and often kill blood-sucking insects. However, this group remains insufficiently investigated wild. This is particularly true leaf warblers Phylloscopidae Alström, Ericson, Olsson & Sundberg common small Old World passerine birds whose haemoproteid parasite diversity vectors remain poorly studied. study reports a new species parasitizing warblers, its susceptible...
Haemoproteus (Parahaemoproteus) species (Haemoproteidae) are widespread blood parasites that can cause disease in birds, but information about their vector species, sporogonic development and transmission remain fragmentary. This study aimed to investigate the complete of four Culicoides nubeculosus test if phylogenies based on cytochrome b gene (cytb) reflect patterns ookinete haemosporidian parasites. Additionally, one cytb lineage was identified level vitro gametogenesis hirundinis...
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...
Culicoides biting midges are small dipterous insects known as biological vectors of arboviruses, protozoa, and filaria parasites worldwide. Many studies on focus trapping them at ground level, without considering the best trap heights for different vector species. This implies that we might overlook positioned higher in canopy. From June to August, used UV traps catch three temperate mature forest areas east Lithuania, Baltic region Europe. We conducted this study test differences midge...
