| 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 |
| 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 |
