| complete development of three species of haemoproteus (haemosporida, haemoproteidae) in the biting midge culicoides impunctatus (diptera, ceratopogonidae). | development of haemoproteus balmorali, h. dolniki, and h. tartakovskyi was followed in experimentally infected biting midges culicoides impunctatus on the curonian spit in the baltic sea. wild-caught flies were allowed to take blood meals on naturally infected spotted flycatchers muscicapa striata, chaffinches fringilla coelebs, or crossbills loxia curvirostra harboring mature gametocytes of these parasites. the engorged biting midges were collected, held at 14-18 c, and dissected daily. mature ... | 2002 | 12435121 |
| 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 |
| the widespread biting midge culicoides impunctatus (ceratopogonidae) is susceptible to infection with numerous haemoproteus (haemoproteidae) species. | haemoproteus parasites are widespread, and some species cause disease in wild and domestic birds. however, the insect vectors remain unknown for the majority of species and genetic lineages of avian haemoproteus. this information is crucial for better understanding the biology of haemoproteids, the epidemiology of haemoproteosis, and the development of morphological characters of sporogonic stages in wildlife haemosporidian parasites. it remains unclear whether the specificity of haemoproteus pa ... | 2017 | 28841905 |
| interactions between hemoparasite status and female age in the primary reproductive output of pied flycatchers. | the relationship between hemoparasite infection (measured just after egg laying) and primary reproductive output (laying date, clutch size and egg volume) was studied in female pied flycatchers, ficedula hypoleuca, of different ages (2 years old vs. 4 or more years old). the hemoparasite (haemoproteus balmorali and trypanosoma spp.) prevalence increased with advancing female age. h. balmorali-infected females initiated egg laying earlier and laid larger clutches. there was no evidence that infec ... | 2001 | 28547446 |
