| survey of blood parasites in two forest owls, northern saw-whet owls and flammulated owls, of western north america. | except for a few studies in the eastern united states, little has been published on hemoparasites in owls. we surveyed the blood parasites of 108 northern saw-whet owls (aegolius acadicus) and 24 flammulated owls (otus flammeolus) in idaho during autumn migration in 1999 and 2000. we also surveyed 15 flammulated owls (flow) during breeding season in utah from 2000. leucocytozoon ziemanni, haemoproteus syrnii, haemoproteus noctuae, and trypanosoma avium were identified. the overall prevalence of ... | 2008 | 18436683 |
| haemoproteus ilanpapernai n. sp. (apicomplexa, haemoproteidae) in strix seloputo from singapore: morphological description and reassignment of molecular data. | haemoproteus ilanpapernai karadjian and landau n. sp. from the spotted wood owl, strix seloputo, in singapore is described from material from ilan paperna's collection of slides. the species was previously identified as haemoproteus syrnii (mayer, 1910). however, comparisons between the material from strix seloputo and our own material from strix aluco, the type host of h. syrnii, revealed morphological and molecular differences. h. ilanpapernai n. sp. differs morphologically from h. syrnii by t ... | 2014 | 24759652 |
| outbreak of avian malaria associated to multiple species of plasmodium in magellanic penguins undergoing rehabilitation in southern brazil. | avian malaria is a mosquito-borne disease caused by plasmodium spp. avian plasmodia are recognized conservation-threatening pathogens due to their potential to cause severe epizootics when introduced to bird populations with which they did not co-evolve. penguins are considered particularly susceptible, as outbreaks in captive populations will often lead to high morbidity and rapid mortality. we used a multidisciplinary approach to investigate an outbreak of avian malaria in 28 magellanic pengui ... | 2014 | 24736326 |
| haemoproteus syrnii in strix aluco from france: morphology, stages of sporogony in a hippoboscid fly, molecular characterization and discussion on the identification of haemoproteus species. | in france, haemoproteus syrnii is frequently found in the tawny owl, strix aluco. additional and complementary features of this species, and in particular the characteristics of volutin, are presented. the authors consider the volutin granules as constant in a given species, and discuss their taxonomic value. these cytoplasmic inclusions appear early during the first stages of development of the gametocytes as an initial granule which multiplies as the parasite develops. they were reported in so ... | 2013 | 24029169 |
| molecular characterization of five widespread avian haemosporidian parasites (haemosporida), with perspectives on the pcr-based detection of haemosporidians in wildlife. | haemosporidians (haemosporida) are cosmopolitan in birds. over 250 species of these blood parasites have been described and named; however, molecular markers remain unidentified for the great majority of them. this is unfortunate because linkage between dna sequences and identifications based on morphological species can provide important information about patterns of transmission, virulence, and evolutionary biology of these organisms. there is an urgent need to remedy this because few experts ... | 2014 | 24728557 |
