mechanisms of mortality in culicoides biting midges due to haemoproteus infection.we examined the effects of haemoproteus infection on the survival and pathology caused in the biting midges. forty-six females of culicoides impunctatus were exposed experimentally by allowing them to feed on a naturally infected red-backed shrike infected with haemoproteus lanii (lineage hrb1, gametocytaemia 5·2%). seventeen females were fed on an uninfected bird (controls). dead insects were collected, counted and used for dissection, histological examination and polymerase chain reaction-base ...201627608600
first data on the genetic diversity of avian haemosporidians in china: cytochrome b lineages of the genera plasmodium and haemoproteus (haemosporida) from gansu province.a total of 76 birds belonging to 23 species and 14 families was examined for the presence of plasmodium spp. and haemoproteus spp. birds were trapped at four localities in gansu province, china, in june-july 2011. dna was isolated from blood samples and parasite detection, and identification was based on pcr assays and sequences of 479 bp of cyt b gene. the total prevalence of haemosporidians was 21.0%. haemoproteus spp. were detected in 14 birds (prevalence 18.4%). the lineage cyapic1 from cyan ...201323851731
hemosporidian blood parasites in seabirds--a comparative genetic study of species from antarctic to tropical habitats.whereas some bird species are heavily affected by blood parasites in the wild, others reportedly are not. seabirds, in particular, are often free from blood parasites, even in the presence of potential vectors. by means of polymerase chain reaction, we amplified a dna fragment from the cytochrome b gene to detect parasites of the genera plasmodium, leucocytozoon, and haemoproteus in 14 seabird species, ranging from antarctica to the tropical indian ocean. we did not detect parasites in 11 of the ...201020652673
in vitro development of haemoproteus parasites: the efficiency of reproductive cells increase during simultaneous sexual process of different lineages.recent in vitro experimental studies reported the complex patterns of haemosporidian (haemosporida) between-lineage interactions, which prevent mixing of lineages during simultaneous sexual process. numerous anomalous ookinetes have been observed; these are not involved in sporogony. massive development of such ookinetes might influence parasite transmission but is insufficiently investigated. the simultaneous sexual process of several lineages is a common phenomenon in vectors due to high preva ...201424481908
further observations on in vitro hybridization of hemosporidian parasites: patterns of ookinete development in haemoproteus spp.increasingly frequent outbreaks of zoonotic infections call for studies of wildlife parasites to reach a better understanding of the mechanisms of host switch, leading to the evolution of new diseases. however, speciation processes have been insufficiently addressed in experimental parasitology studies, primarily due to difficulties in determining and measuring mate-recognition signals in parasites. we investigated patterns of sexual process and ookinete development in avian haemoproteus (paraha ...201322924917
haemoproteus infections (haemosporida, haemoproteidae) kill bird-biting mosquitoes.haemoproteus parasites (haemosporida, haemoproteidae) are widespread; some species cause severe diseases in avian hosts. heavy haemoproteus infections are often lethal for biting midges (ceratopogonidae), which transmit avian haemoproteids, but there is no information regarding detrimental effect on other blood-sucking insects. we examined effects of haemoproteus tartakovskyi (lineage hsiskin1), haemoproteus lanii (lineages hrb1and hrbs2) and haemoproteus balmorali (lineage hcoll3) on the surviv ...201424337545
detrimental effects of haemoproteus infections on the survival of biting midge culicoides impunctatus (diptera: ceratopogonidae).the effects of haemoproteus belopolskyi, haemoproteus fringillae, and haemoproteus lanii on the survival of their vector the biting midge culicoides impunctatus were examined. wild-caught females were infected experimentally by allowing them to feed on naturally infected birds. a group of flies, which fed on an uninfected bird, was used as a control. there was a highly significant difference in the survival rate between the noninfected group and all groups of infected flies for postfeeding (pf) ...200415040695
