| [ocurrence of ornithonyssus bursa (berlese, 1888) (acari: macronyssidae) on megascops choliba (tropical screech-owl) and pitangus sulphuratus (great kiskadee) nestlings in the rio grande do sul state, brazil]. | the center for rehabilitation of wildlife and center for selection of wild animal of the federal university of pelotas has attended two nestlings of megascops choliba (tropical screech-owl) (strigiformes - strigidae) and two of pitangus sulphuratus (great kiskadee) (passeriformes - tyrannidae) heavily parasitized by mites, in may 2005 and december 2006, respectively. the nestlings and the nest of p. sulphuratus were collected in the pelotas urban area after severe storms. the mites were removed, ... | 2009 | 20040213 |
| habitat selection by owls in a seasonal semi-deciduous forest in southern brazil. | this paper tested the hypothesis that the structural components of vegetation have impact over the distribution of owl species in a fragment of a semi-deciduous seasonal forest. this paper also determined which vegetation variables contributed to the spatial distribution of owl species. it was developed in the perobas biological reserve (pbr) between september and december 2011. to conduct the owl census, a playback technique was applied at hearing points distributed to cover different vegetatio ... | 2015 | 26602354 |
| diversity of quill mites of the family syringophilidae (acari: prostigmata) parasitizing owls (aves: strigiformes) with remarks on the host-parasite relationships. | the quill mite fauna of the family syringophilidae (acari: prostigmata: cheyletoidea) associated with owls (aves: strigiformes) is reviewed. a new genus is proposed, neobubophilus skoracki & unsoeld gen. nov. it differs from closely related bubophilus (bubophilus philips and norton, 1978) by the absence of leg setae vsii in the both sexes. in addition, four new species are described: (1) neobubophilus cunicularius skoracki & unsoeld sp. nov. from athene cunicularia (molina, 1782) (strigidae) fro ... | 2016 | 27220744 |
| cystoidosoma hermaphroditus sp. n., the first representative of the quill mite family ascouracaridae (acari: astigmata: pterolichoidea) from an owl (aves: strigiformes). | the mite family ascouracaridae gaud et atyeo, 1976 contains large-sized mites (mostly > 1 mm) which live inside the quills of birds of several orders. to date, no representative of this family has been found associated with the order strigiformes (owls). in this paper, a new species of this family, cystoidosoma hermaphroditus sp. n., is described from the tropical screech owl, megascops choliba (vieillot) (aves: strigiformes) from brazil. this species is unique in having an external spermaduct, ... | 2015 | 26277919 |
| genetic diversity of toxoplasma gondii isolates obtained from free-living wild birds rescued in southeastern brazil. | recent studies carried out in brazil have shown that strains from the same toxoplasma gondii genotype can infect humans, domestic animals (dogs and cats) and animals slaughtered for human consumption (pigs, sheep, goats, and chickens), suggesting a common infection route. however, little is known about the importance of free-living wild birds within this epidemiological context. the objective of this work was to isolate, genotype, and evaluate the virulence for mice of new isolates of t. gondii ... | 2018 | 30479944 |
| lws visual pigment in owls: spectral tuning inferred by genetics. | owls constitute a diverse group of raptors, active at different times of the day with distinct light conditions that might be associated with multiple visual adaptations. we investigated whether shifts in the spectral sensitivity of the l cone visual pigment, as inferred by analysis of gene structure, could be one such adaptive mechanism. using sanger sequencing approach, we characterized the long wavelength-sensitive (lws) opsin gene expressed in the retina of five owl species, specifically cho ... | 2019 | 31706045 |
| inclusion body hepatitis caused by aviadenovirus in a tropical screech owl (megascops choliba). | in 2016, tropical screech owl (megascops choliba) (tso) chicks were suddenly found dead in a japanese breeding facility. we autopsied a 9-day-old tso and discovered white spots scattered on the liver surface. multifocal necrosis was diffused, and macrophages had infiltrated the necrotic hepatic lesions. hepatocytes contained numerous intranuclear inclusion bodies. immunohistochemical staining detected adenovirus antigen only in the liver. next, pcr and sequencing (lc536616) identified tso adenov ... | 2020 | 32684609 |
| identification of two novel adenoviruses in smooth-billed ani and tropical screech owl. | avian adenoviruses (advs) are a very diverse group of pathogens causing diseases in poultry and wild birds. wild birds, endangered by habitat loss and habitat fragmentation in the tropical forests, are recognised to play a role in the transmission of various advs. in this study, two novel, hitherto unknown advs were described from faecal samples of smooth-billed ani and tropical screech owl. the former was classified into genus aviadenovirus, the latter into genus atadenovirus, and both viruses ... | 2020 | 32109945 |
| draft genome sequence of multidrug-resistant enterococcus faecium strain e1298, with a sequence type 1274 profile, recovered from the cloacal microbiome of a tropical screech owl (megascops choliba) in rio de janeiro, brazil. | here, we present the draft genome sequence of enterococcus faecium strain e1298, a representative of the clonal complex 17 (cc17), identified as sequence type 1274 (st1274) and resistant to multiple classes of antimicrobials, isolated from the cloaca of a tropical screech owl (megascops choliba) in rio de janeiro, brazil. | 2019 | 31000546 |
