| avian trichomonosis in spotted owls (strix occidentalis): indication of opportunistic spillover from prey. | avian trichomonosis, caused by the flagellated protozoan parasite trichomonas gallinae, has variable pathogenicity among bird species ranging from asymptomatic infections to severe disease periodically manifesting in epidemic mortality. traditionally, columbids are identified as highly susceptible to infection with occasional spillover into raptors that prey on infected birds. we identified avian trichomonosis in two dead california spotted owls (strix occidentalis occidentalis) and three dead n ... | 2016 | 27833856 |
| ecologic drivers and population impacts of avian trichomonosis mortality events in band-tailed pigeons (patagioenas fasciata) in california, usa. | : avian trichomonosis, a disease typically caused by the protozoan parasite trichomonas gallinae , is a well recognized cause of death in many avian species. in california, us, trichomonosis has caused periodic epidemics in pacific coast band-tailed pigeons ( patagioenas fasciata monilis). we summarize reported mortality events and investigate ecologic drivers and population impacts associated with epidemic mortality due to trichomonosis in band-tailed pigeons. between 1945 and 2014, 59 mortal ... | 2016 | 27187033 |
| two new quill mite species of the genus psittaciphilus fain, bochkov & mironov, 2000 (acariformes: syringophilidae) associated with pigeons and doves (columbiformes: columbidae). | two new quill mite species of the genus psittaciphilus fain, bochkov & mironov, 2000 (acariformes: prostigmata: syringophilidae) collected from columbiform birds (columbiformes) are described: psittaciphilus montanus n. sp. form the ruddy quail-dove geotrygon montana gosse from trinidad and tobago, brazil and panama, and psittaciphilus patagioenas n. sp. from the band-tailed pigeon patagioenas fasciata (say) from colombia and the scaled pigeon patagioenas speciosa (gmelin) from surinam. a key to ... | 2018 | 30353298 |
| avian trichomonosis mortality events in band-tailed pigeons (patagioenas fasciata) in california during winter 2014-2015. | avian trichomonosis is an upper digestive tract disease of birds typically caused by the protozoan parasite trichomonas gallinae. in california (u.s.a), trichomonosis is known to cause periodic epidemics in the pacific coast band-tailed pigeon (patagioenas fasciata monolis), a migratory upland game bird. we summarize the mortality events that occurred during winter 2014-2015 including the duration, estimated mortality, pathology, and genetic identity of infecting parasites. increased mortality w ... | 2018 | 30073142 |
| natural selection shaped the rise and fall of passenger pigeon genomic diversity. | the extinct passenger pigeon was once the most abundant bird in north america, and possibly the world. although theory predicts that large populations will be more genetically diverse, passenger pigeon genetic diversity was surprisingly low. to investigate this disconnect, we analyzed 41 mitochondrial and 4 nuclear genomes from passenger pigeons and 2 genomes from band-tailed pigeons, which are passenger pigeons' closest living relatives. passenger pigeons' large population size appears to have ... | 2017 | 29146814 |
| husbandry protocols for the band-tailed pigeon, patagioenas fasciata albilinea, at the wcs, bronx zoo for future conservation management programs. | from 2015 to 2016 we determined the husbandry protocols involved in the captive rearing of the band-tailed pigeon (btpi), patagioenas fascinate albilinea, for use as a tool in the future management of like extant and extinct avian taxa. current and historical ex-situ conservation management of btpis and the closely related passenger pigeon, ectopistes migratorius, is limited in scope and required further examination. focus on the btpi within zoos and private aviculture facilities is currently la ... | 2018 | 29243311 |
| tetratrichomonas and trichomonas spp.-associated disease in free-ranging common eiders ( somateria mollissima) from wellfleet bay, ma and description of its1 region genotypes. | during an outbreak of wellfleet bay virus (wfbv) in common eiders ( somateria mollissima) from the cape cod region of massachusetts, several birds were diagnosed with trichomonosis consisting of multiple trichomonad species. six birds were examined, with trichomonads found in ceca in four birds and associated typhlitis in three of these four birds. pcr and dna sequencing utilizing trichomonad-specific primers targeting the its1 region of the ribosomal dna (rdna) revealed the presence of tetratri ... | 2018 | 29620469 |
| antireflection-enhanced color by a natural graded refractive index (grin) structure. | nanostructured materials like graded refractive index (grin) structures in moth eyes have inspired the design of novel antireflective coatings. such structures are more flexible than uniform coatings, but applications have been mainly limited to broadband antireflection in solar cells and leds. here we show that cylindrical pigment granules in two bird species (polyplectron bicalcaratum and patagioenas fasciata) form a grin that suppresses interference and expands the range of colors produced by ... | 2014 | 24922372 |
| dual-pathogen etiology of avian trichomonosis in a declining band-tailed pigeon population. | the pacific coast band-tailed pigeon (patagioenas fasciata monilis) is a migratory game bird of north america that is at risk for population decline. epidemics of avian trichomonosis caused by upper digestive tract infection with trichomonas spp. protozoa in these and other doves and pigeons of the united states are sporadic, but can involve tens of thousands of birds in a single event. herein, we analyze the role of trichomonosis in band-tailed pigeon mortality and relate spatial, temporal and ... | 2014 | 24632451 |
| trichomonas stableri n. sp., an agent of trichomonosis in pacific coast band-tailed pigeons (patagioenas fasciata monilis). | trichomonas gallinae is a ubiquitous flagellated protozoan parasite, and the most common etiologic agent of epidemic trichomonosis in columbid and passerine species. in this study, free-ranging pacific coast band-tailed pigeons (patagioenas fasciata monilis) in california (usa) were found to be infected with trichomonad protozoa that were genetically and morphologically distinct from t. gallinae. in microscopic analysis, protozoa were significantly smaller in length and width than t. gallinae an ... | 2014 | 24918075 |
