possible role of birds and ticks in the dissemination of bhanja virus.	several wild birds (4 fringilla coelebs, 1 coccothraustes coccothraustes and 2 erithacus rubecula) were inoculated subcutaneously with bhanja virus (bhav). no clinical symptoms of infection were observed in any of the birds; a low viremia was demonstrated only in c. coccothraustes (2 and 4 days p.i.), seroconversion in all birds. bhav was not isolated from organs 32 days p.i. consequently, the tested birds do not seem to serve as "amplifying hosts" of bhav. the paper includes a survey of geograp ...	1982	6800906
[a study on location of vocalization centres in hawfinch (coccothraustes coccothraustes)].	vocal-control nuclei in hawfinch (coccothraustes coccothraustes) were studied by hrp retrograde tracing and electrophysiological methods. vocal control centres in hawfinch consist of four discrete nuclei. hyperstriatum ventral, pars caudale (hvc) is the highest nucleus, with its efferent fibers projecting to the rubust nucleus of archistriatum (ra), which in turn projects to the nucleus intercollicularis (ico) of midbrain and the nucleus intermedius (im) of medulla oblongata im innervating vocal ...	1990	2263956
phylogeography of crossbills, bullfinches, grosbeaks, and rosefinches.	mitochondrial cytochrome b (cyt b) from 24 carduelini species including crossbills, bullfinches, grosbeaks, rosefinches, and other related, but not conclusively classified species, was sequenced. these sequences were also compared with all the available sequences from the genera carduelis, serinus, and passer. phylogenetic analyses consistently gave the same groups of finches and the calculated divergence times suggest that speciation of the studied species occurred between 14 and 3 million year ...	2001	11529508
borrelia burgdorferi sensu lato infection in passerine birds from the mazurian lake region (northeastern poland).	the aim of the present study was to evaluate a potential role of different passerine birds species in mazurian lake region (northeast poland) in the spread of borrelia burgdorferi sensu lato, the spirochaete that causes lyme disease. a total number of 1254 birds (representing 42 species) were captured during the 3-year study period. blood samples were collected from birds and analyzed with a nested polymerase chain reaction technique in order to detect fragments of the pathogen dna. positive res ...	2004	14681070
subalar cutaneous cysts with harpirhynchus nidulans in bearded tits and hawfinches in central europe.	in wild bearded tits (panurus biarmicus) and hawfinches (coccothraustes coccothraustes) trapped in the czech republic and slovakia from 1999 to 2003, characteristic yellow thin-walled subalar cutaneous cysts filled with friable material containing mites harpirhynchus nidulans were found. the biggest cysts were 14 mm and 20 mm in size in bearded tits and in hawfinches, respectively. histologically, the relatively thick wall of cysts contained erythrocytes (extravased or in small vessels) and hete ...	2005	15763736
comparative studies of the dorsal surface of the tongue in three avian species by scanning electron microscopy.	the dorsal lingual surfaces of adult blue-and-white flycatcher, hawfinch, and japanese white-eye were examined by scanning electron microscopy. the tongue of the blue-and-white flycatcher shows a conical shape and a median groove is observed on the anterior lingual apex. the tongue of the hawfinch shows a cuspid-like shape and a median groove and separation of the lingual apex are not observed. many processes are observed in the tip of the tongue of the japanese white-eye. results of morphologic ...	2010	20560446
first report of epizootic trichomoniasis in wild finches (family fringillidae) in southern fennoscandia.	forty-one outbreaks of mortality in wild finches were reported in southern norway, sweden, and finland in the second half of 2008 (n = 40) and in february 2009 (n = 1). greenfinches (carduelis chloris) and occasional chaffinches (fringilla coelebs) primarily were affected. forty-eight greenfinches, eight chaffinches, one hawfinch (coccothraustes coccothraustes), and one blue tit (parus caeruleus) from 22 incidents were examined postmortem. birds were in poor nutritional condition and had necroti ...	2010	20408413
a survey of biting midges of the genus culicoides latreille, 1809 (diptera: ceratopogonidae) in ne bulgaria, with respect to transmission of avian haemosporidians.	this study presents data from a molecular survey of the species of the genus culicoides from the region of kalimok field station (ne bulgaria) and haemosporidian parasites occurring in them in order to investigate the host-parasite specificity of haemosporidians to their dipteran vectors. the identification of culicoides spp. was carried out by morphological and molecular-genetic methods. we collected and analysed 230 individuals of the genus culicoides. nine species were found. eight species we ...	2013	24338323
two new species of haemoproteus kruse, 1890 (haemosporida, haemoproteidae) from european birds, with emphasis on dna barcoding for detection of haemosporidians in wildlife.	two new species of haemoproteus kruse, 1890 (haemosporida, haemoproteidae) are described: haemoproteus (parahaemoproteus) homovelans n. sp. from grey-faced woodpecker, picus canus gmelin, and haemoproteus (parahaemoproteus) concavocentralis n. sp. recorded in hawfinch, coccothraustes coccothraustes (linnaeus), both sampled in bulgaria. the morphology of the gametocytes and their host-cells are described and mitochondrial cytochrome b (cyt b) gene sequences are generated. haemoproteus homovelans ...	2014	24474037
