| 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 |
| trichomonas gypaetinii n. sp., a new trichomonad from the upper gastrointestinal tract of scavenging birds of prey. | in the context of an epidemiological study carried out by several wildlife recovery centers in spain, trichomonads resembling trichomonas gallinae were found in the oropharyngeal cavity of 2 egyptian vultures (neophron percnopterus) and 14 cinereous vultures (aegypius monachus) which did not show any symptoms of trichomonosis. in order to characterize them, these isolates along with seven other t. gallinae isolates obtained from different hosts and from different geographical origin were analyze ... | 2015 | 25273632 |
