| prevalence of lyme disease borrelia spp. in ticks from migratory birds on the japanese mainland. | borrelia sp. prevalence in ticks on migratory birds was surveyed in central japan. in autumn, a total of 1,733 birds representing 40 species were examined for ticks. a total of 361 ticks were obtained from 173 birds of 15 species, and these ticks were immature haemaphysalis flava (94.4%), haemaphysalis longicornis, ixodes columnae, ixodes persulcatus, ixodes turdus, and an unidentified ixodes species. of these, 27 juveniles of h. flava on turdus pallidus, turdus cardis, or emberiza spodocephala, ... | 2000 | 10698761 |
| mosquito blood-meal analysis for avian malaria study in wild bird communities: laboratory verification and application to culex sasai (diptera: culicidae) collected in tokyo, japan. | we conducted laboratory experiments to verify molecular techniques of avian malaria parasite detection distinguishing between an infected mosquito (oocysts on midgut wall) and infective mosquito (sporozoites in salivary glands) in parallel with blood-meal identification from individual blood-fed mosquitoes prior to application to field survey for avian malaria. domestic fowl infected with plasmodium gallinaceum was exposed to a vector and non-vector mosquito species, aedes aegypti and culex pipi ... | 2009 | 19629522 |
| susceptibility of two species of wild terrestrial birds to infection with a highly pathogenic avian influenza virus of h5n1 subtype. | the recent epidemic caused by h5n1 highly pathogenic avian influenza (hpai) viruses has spread over many parts of asia, europe and africa. wild birds, particularly waterfowl, are considered to play a role in viral dissemination. however, detailed information on whether wild terrestrial birds act as carriers is currently unavailable. to investigate the susceptibility of terrestrial birds to hpai viruses, two species of wild bird (great reed warbler and pale thrush) that are common in east asia we ... | 2010 | 20390543 |
| molecular detection of anaplasma, bartonella, and borrelia species in ticks collected from migratory birds from hong-do island, republic of korea. | bird migration is a recurring annual and seasonal event undertaken by more than 100 species of birds in the southeast asian and northeast palearctic regions that pass through or remain for short periods from april to may and september to november at hong-do island, republic of korea (rok). a total of 212 ticks (40 haemaphysalis flava, 12 h. longicornis, 146 ixodes turdus, 13 i. nipponensis, and 1 i. ornithophila) were collected from 65/2,161 (3.0%) migratory birds consisting of 21 species that w ... | 2013 | 23428091 |
| susceptibility of wild passerines to subtype h5n1 highly pathogenic avian influenza viruses. | highly pathogenic avian influenza (hpai) viruses of the h5n1 subtype have spread throughout many areas of asia, europe and africa, and numerous cases of hpai outbreaks in domestic and wild birds have been reported. although recent studies suggest that the dissemination of h5n1 viruses is closely linked to the migration of wild birds, information on the potential for viral infection in species other than poultry and waterfowl is relatively limited. to investigate the susceptibility of terrestrial ... | 2015 | 26274569 |
| genetic identification for prey birds of the endangered peregrine falcon (falco peregrinus). | to reveal the dietary ecology of the peregrine falcon (falco peregrinus), we conducted a molecular analysis for mitochondrial genes (coi and cytb) to identify the prey species collected from a feeding place found on sasu island, south korea. the results from noninvasive genetic analysis showed that the sequences obtained came from nine species of birds (cuculus canorus, eurystomus orientalis, limosa limosa, microscelis amaurotis, oriolus chinensis, phasianus colchicus, sterna hirundo, streptopel ... | 2017 | 28071972 |
| tandem duplications in the c-terminal domain of the mesotocin receptor exclusively identified among east eurasian thrushes. | mesotocin is a neurohypophyseal hormone found in some non-mammalian vertebrates, including birds, reptiles, and amphibians. in this study, we identified and characterized 18-amino acid duplications in the c-terminal domain of the mesotocin receptor (mtr), specifically found in turdus thrushes (aves: passeriforms: turdidae). these duplicated elements are located in the distal part of the c-terminal tails of mtr and consist of amino acids that are highly conserved among major vertebrates. intraspe ... | 2013 | 24193891 |
| ticks collected from migratory birds, including a new record of haemaphysalis formosensis, on jeju island, korea. | migratory birds may disperse parasites across ecological barriers, and recent climate change may alter the pattern of ectoparasite dispersal via changed patterns of bird migration. in order to document the parasitization of migratory birds by ixodidae ticks on jeju island in korea, we examined 934 migratory birds comprising 75 species for ticks from 2010 to 2012. in total, 313 ticks were collected from 74 migratory birds across 17 avian species and identified based on morphological keys. these t ... | 2014 | 24141529 |
