| molecular identity and heterogeneity of trichomonad parasites in a closed avian population. | columbids (pigeons and doves) are the primary host of trichomonas gallinae, the flagellate protozoon which causes avian trichomoniasis, a widespread, often lethal disease. although predominantly apathogenic, the organism is paradigmatic for the study of strain-specific virulence, with some strains causing greater than 75% mortality and epizootic die-offs in wildlife populations. in recent years, research on this important emerging pathogen has been neglected and genetic variation within the para ... | 2007 | 17320488 |
| trichomonas gallinae in mauritian columbids: implications for an endangered endemic. | although well known as a widespread parasitic disease of columbids and birds of prey, there have been few studies of trichomonosis in populations of wild birds. in mauritius, trichomonosis has been highlighted as a major threat to an endangered endemic, the pink pigeon (neosoenas [columba] mayeri). in this study, we examined the role that populations of other columbids in mauritius might be playing as infectious reservoirs of the causal flagellate protozoan, trichomonas gallinae. we screened 296 ... | 2007 | 17699078 |
| trichomonad infection in endemic and introduced columbids in the seychelles. | island endemic avifaunas face many threats, including the now well-documented impacts of pathogens. the impacts of pathogens on the endemic seychelles avifauna, however, have been little studied. the protozoan parasite trichomonas gallinae has been shown to reduce survival and reproductive success of the endemic pink pigeon columba mayeri on the nearby island of mauritius. i investigated trichomonad infection prevalence and pathogenicity in endemic seychelles blue pigeons, alectroenas pulcherrim ... | 2011 | 21719842 |
