| [gametogenesis and zygote and ookinete formation in some haemoproteid species (haemosporidia: haemoproteidae) of birds in vitro]. | observations were made through examination of thin blood films which were prepared at appropriate intervals from citrated fresh blood of infected birds. the comparative description of gametogenesis, zygote and ookinete formation of haemoproteus tartakovskyi, h. belopolskyi, h. fringillae, h. pallidus under the light microscope is given for the first time. this process has a general pattern for all investigated haemoproteid species. it is shown that macrogametocyte has been transformed directly t ... | 1993 | 8474762 |
| in vitro hybridization of haemoproteus spp.: an experimental approach for direct investigation of reproductive isolation of parasites. | in spite of their potential as model organisms and their medical importance, parasite speciation processes have been insufficiently discussed in the general literature. scarcity of experimental data regarding reproductive isolation of parasites is a serious obstacle. toward this end we developed a method for the investigation of hybridization of hemosporidian parasites in vitro. five species of haemoproteus (haemosporida, haemoproteidae) were isolated from naturally infected passerine birds. the ... | 2008 | 19127967 |
| 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 ... | 2014 | 24337545 |
| abortive long-lasting sporogony of two haemoproteus species (haemosporida, haemoproteidae) in the mosquito ochlerotatus cantans, with perspectives on haemosporidian vector research. | haemoproteus spp. are cosmopolitan vector-born haemosporidian parasites, some species of which cause diseases in non-adapted birds. recent polymerase chain reaction (pcr)-based studies have detected mitochondrial cytochrome b gene lineages of these haemoproteus parasites in blood-sucking mosquitoes and speculated about possible involvement of these insects in transmission of avian haemoproteids. however, development of haemoproteus lineages has not been documented in mosquitoes. we infected 304 ... | 2013 | 23504040 |
| 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 ... | 2013 | 22924917 |
| 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 ... | 2014 | 24481908 |
| the genome of haemoproteus tartakovskyi and its relationship to human malaria parasites. | the phylogenetic relationships among hemosporidian parasites, including the origin of plasmodium falciparum, the most virulent malaria parasite of humans, have been heavily debated for decades. studies based on multiple-gene sequences have helped settle many of these controversial phylogenetic issues. however, denser taxon sampling and genome-wide analyses are needed to confidently resolve the evolutionay relationships among hemosporidian parasites. genome sequences of several plasmodium parasit ... | 2016 | 27190205 |
| haemoproteus tartakovskyi (haemoproteidae): complete sporogony in culicoides nubeculosus (ceratopogonidae), with implications for avian haemoproteid experimental research. | numerous recent studies have addressed the molecular characterization, distribution and genetic diversity of haemoproteus spp. (haemoproteidae). some species of these blood parasites cause severe disease in birds, and heavy infections are often lethal in biting midges (ceratopogonidae) and other blood-sucking insects. however, information about the vectors of haemoproteids is scarce. this presents an obstacle for better understanding the mechanisms of host-parasite interactions and the epidemiol ... | 2016 | 26616347 |
