| trichomonas gallinae in columbiform birds from the galapagos islands. | domestic pigeons were introduced into the galapagos islands in 1972 or 1973. there is a high prevalence of trichomonas gallinae among them and some evidence of canker. trichomonas gallinae can be found also in endemic galapagos doves in the vicinity of puerto ayora on santa cruz island. doves examined on pigeon-free islands were not found infected. | 1987 | 3625913 |
| survey for haemoproteus spp., trichomonas gallinae, chlamydophila psittaci, and salmonella spp. in galapagos islands columbiformes. | endemic free-ranging galapagos doves (zenaida galapagoensis) and introduced rock doves (columba livia) were surveyed in several islands of the galapagos archipelago to establish sample prevalence of hemoparasites, trichomonas gallinae, chlamydophila psittaci, and salmonella species. a haemoproteus sp., the only hemoparasite identified, was found in 89% of the galapagos doves sampled but not in the rock doves. trichomonas gallinae was detected by polymerase chain reaction in 44% of rock doves fro ... | 2004 | 15193075 |
| differences in straggling rates between two genera of dove lice (insecta: phthiraptera) reinforce population genetic and cophylogenetic patterns. | differences in dispersal abilities have been implicated for causing disparate evolutionary patterns between columbicola and physconelloides lice (insecta: phthiraptera). however, no study has documented straggling (when lice are found on atypical hosts) rates within these lineages. we used the fact that the galapagos hawk, buteo galapagoensis (gould) (falconiformes) feeds on the galapagos dove zenaida galapagoensis gould (columbiformes) within an ecologically simplified setting. the galapagos do ... | 2004 | 15380682 |
| phylogenetic relationships of haemosporidian parasites in new world columbiformes, with emphasis on the endemic galapagos dove. | dna-sequence analyses of avian haemosporidian parasites, primarily of passerine birds, have described the phylogenetic relationships of major groups of these parasites, which are in general agreement with morphological taxonomy. however, less attention has been paid to haemosporidian parasites of non-passerine birds despite morphological and dna-sequence evidence for unique clades of parasites in these birds. detection of haemosporidian parasites in the galapagos archipelago has raised conservat ... | 2010 | 19854196 |
| a new haemoproteus species (haemosporida: haemoproteidae) from the endemic galapagos dove zenaida galapagoensis, with remarks on the parasite distribution, vectors, and molecular diagnostics. | haemoproteus (haemoproteus) multipigmentatus n. sp. (haemosporida, haemoproteidae) was found in the endemic galapagos dove zenaida galapagoensis . it is described based on the morphology of its blood stages and segments of the mitochondrial cytochrome b gene, which can be used for molecular identification and diagnosis of this species. haemoproteus multipigmentatus can be readily distinguished from all species of hemoproteids of the subgenus haemoproteus , primarily due to numerous (approximatel ... | 2010 | 20486741 |
| patterns of parasite abundance and distribution in island populations of galápagos endemic birds. | parasite life-history characteristics, the environment, and host defenses determine variation in parasite population parameters across space and time. parasite abundance and distribution have received little attention despite their pervasive effects on host populations and community dynamics. we used analyses of variance to estimate the variability of intensity, prevalence, and abundance of 4 species of lice (insecta: phthiraptera) infecting galápagos doves and galápagos hawks and 1 haemosporidi ... | 2008 | 18605785 |
| from galapagos doves to passerines: spillover of haemoproteus multipigmentatus. | haemoproteus (haemoproteus) multipigmentatus, a haemosporidian parasite thought to be specific to columbiform birds, was detected in passeriform birds on santiago island in the galapagos archipelago. we surveyed birds along an altitudinal gradient on the islands of santa cruz, isabela and santiago between june 2013 and july 2015. molecular screening of 2254 individuals from 25 species of endemic and introduced birds revealed clusters of passerine birds positive for h. multipigmentatus on santiag ... | 2017 | 28736699 |
| atypical poxvirus lesions in two galapagos doves (nesopelia g. galapagoensis). | two galapagos doves were received for necropsy. the only lesions detected were small firm foci throughout the lungs, suspected to be neoplastic. sections of lung tissues showed the foci as dense, solid masses of epithelioid cells. electron microscopy revealed pox virions in the lesions. this is the first report on galapagos doves with poxvirus infection in the lungs with tumour-like growth. | 2001 | 19184890 |
