| the fine structure of elongate gametocytes of leucocytozoon ziemanni (laveran). | in an effort to establish comparative data within the genus leucocytozoon, elongate gametocytes of l. ziemanni from naturally infected great horned owls (bubo virginianus) were examined by electron microscopy. micro- and macrogametocytes proved to be easily distinguishable at the electron microscopic level due to dramatic dimorphism at maturity and cytoplasmic and nuclear morphology. the parasite membrane architecture, number and type of cytoplasmic ribosomes of both micro- and macrogametocytes, ... | 1978 | 105117 |
| hematozoa from the spotted owl. | one hundred five spotted owls (strix occidentalis) from seven populations and three subspecies were examined for hematozoa. haemoproteus noctuae, h. syrnii, leucocytozoon ziemanni, trypanosoma avium, atoxoplasma sp. and unidentified microfilariae were recorded. all northern (s. occidentalis caurina), california (s. occidentalis occidentalis) and mexican (s. occidentalis lucida) spotted owls were infected with at least one hematozoan; 79% had multiple infections. twenty-two percent of the owls we ... | 1989 | 2810564 |
| fatal combined infection with haemoproteus noctuae and leucocytozoon ziemanni in juvenile snowy owls (nyctea scandiaca) | two juvenile snowy owls (nyctea scandiaca) died after short episodes of lethargy and anorexia. postmortem examination of the first was inconclusive but clinical and laboratory examinations on the second owlet revealed a high level of erythrocyte parasitaemia by haemoproteus noctuae. after a period of intensive nursing and chemotherapy during which it improved clinically and the red cell parasitism decreased, the bird's condition relapsed and it died. postmortem examination revealed h noctuae inf ... | 1998 | 9717222 |
| 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 |
| pcr-based detection and genotyping of haematozoa (protozoa) parasitizing eagle owls, bubo bubo. | we genetically analysed haematozoa parasites (protozoa) isolated from nestling eagle owls (bubo bubo) in toledo province, central spain. a total of 206 nestlings from 74 nests were screened for parasites of the genera leucocytozoon, plasmodium, and haemoproteus using a very efficient polymerase chain reaction (pcr) approach that amplifies a partial segment of the mitochondrial cytochrome b gene of these parasites. pcr-based detection and sequence analyses revealed a unique lineage of leucocytozo ... | 2009 | 18818949 |
