| [attacks of bloodsucking biting midges on birds in the forests of prikam'ia]. | 63 nests of 11 species of birds were examined in the mid-taiga forests of prikamje from 1971 to 1973. 710 specimens of midges were caught within this period. 8 species of midges attacked birds. of them the most abundant was culicoides cubitalis edw. (62.8%). rather numerous were c. sajanicus mirz. (14.9%) and c. reconditus c. et p.-c (11.9%). the other species were few in number or rare. in closed nests c. reconditus c. et p.-c. (42.1%) prevailed. one fourth of caught females were with blood (26 ... | 1975 | 1143930 |
| hyaluronidase of bloodsucking insects and its enhancing effect on leishmania infection in mice. | salivary hyaluronidases have been described in a few bloodsucking arthropods. however, very little is known about the presence of this enzyme in various bloodsucking insects and no data are available on its effect on transmitted microorganisms. here, we studied hyaluronidase activity in thirteen bloodsucking insects belonging to four different orders. in addition, we assessed the effect of hyaluronidase coinoculation on the outcome of leishmania major infection in balb/c mice. | 2008 | 18820742 |
| culicoides species communities associated with wild ruminant ecosystems in spain: tracking the way to determine potential bridge vectors for arboviruses. | the genus culicoides latreille 1809 is a well-known vector for protozoa, filarial worms and, above all, numerous viruses. the bluetongue virus (btv) and the recently emerged schmallenberg virus (sbv) are responsible for important infectious, non-contagious, insect-borne viral diseases found in domestic ruminants and transmitted by culicoides spp. both of these diseases have been detected in wild ruminants, but their role as reservoirs during the vector-free season still remains relatively unknow ... | 2015 | 26510136 |
| hyaluronidase activity in saliva of european culicoides (diptera: ceratopogonidae). | biting midges of the genus culicoides transmit pathogens of veterinary importance such as bluetongue virus (reoviridae: orbivirus). the saliva of culicoides is known to contain bioactive molecules including peptides and proteins with vasodilatory and immunomodulative properties. in this study, we detected activity of enzyme hyaluronidase in six culicoides species that commonly occur in europe and that are putative vectors of arboviruses. hyaluronidase was present in all species studied, although ... | 2015 | 26487248 |
| the geographical distribution and first molecular analysis of culicoides latreille (diptera: ceratopogonidae) species in the southern and southeastern turkey during the 2012 outbreak of bovine ephemeral fever. | this study investigated the geographical distribution and molecular analysis of culicoides species in the southern and southeastern turkey during the 2012 outbreak of bovine ephemeral fever (bef). the midge specimens caught by onderstepoort-type light traps from livestock farms were tested for molecular evidence of existence of viral genome. blood specimens were collected from clinically bef-suspected acute febrile cattle. total nucleic acid samples obtained from field specimens were checked aga ... | 2014 | 25199552 |
| herpetomonas ztiplika n. sp. (kinetoplastida: trypanosomatidae): a parasite of the blood-sucking biting midge culicoides kibunensis tokunaga, 1937 (diptera: ceratopogonidae). | herein, we describe the first case of a natural infection of biting midges by a kinetoplastid protozoan. flagellates from a female culicoides kibunensis captured in a bird's nest were introduced into culture and characterized by light and electron microscopy. however, because the morphological data were inconclusive, the novel endosymbiont-free trypanosomatid was assigned into herpetomonas primarily on the basis of the 18s and 5s ribosomal rna (rrna) gene sequences. | 2004 | 15165057 |
| free-living ciliates as potential reservoirs for eukaryotic parasites: occurrence of a trypanosomatid in the macronucleus of euplotes encysticus. | flagellates of the family trypanosomatidae are obligate endoparasites, which can be found in various hosts. several genera infect insects and occur as monoxenous parasites especially in representatives of diptera and hemiptera. these trypanosomatid flagellates probably share the worldwide distribution of their hosts, which are often infested by large numbers of endoparasites. traditionally, their taxonomy was based on morphology, host origin, and life cycle. here we report the characterization o ... | 2014 | 24774858 |
| urban forests as hubs for novel zoonosis: blood meal analysis, seasonal variation in culicoides (diptera: ceratopogonidae) vectors, and avian haemosporidians. | culicoides vectors can transmit a diverse array of parasites and are globally distributed. we studied feeding preferences and seasonal variation of culicoides (diptera: ceratopogonidae) vectors in an urban forest of germany to determine whether humans living nearby are readily exposed to vector-borne parasites from wild animals. we used a fragment of the mtdna coi gene to identify hosts from blood meals. we amplified a fragment of the mtdna cyt b to detect haemosporidian infections in culicoides ... | 2013 | 23981661 |
| avian haemosporidians in haematophagous insects in the czech republic. | the degree to which avian haemosporidian parasites can exploit different vectors as a definitive host has ecological implications for their transmission and biogeography. studies targeting haemosporidian parasites using precise molecular detection methods are almost lacking in central europe, however. here, we utilized pcr-based molecular methods to detect avian haemosporidians in insect vectors in the czech republic. nine lineages of parasites belonging to three genera, haemoproteus, plasmodium ... | 2013 | 23224608 |
