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 ...19892810564
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 ...19989717222
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 ...200818436683
haemosporidian blood parasites in european birds of prey and owls.avian blood parasites have been intensively studied using morphological methods with limited information on their host specificity and species taxonomic status. now the analysis of gene sequences, especially the mitochondrial cytochrome b gene of the avian haemosporidian species of haemoproteus, plasmodium, and leucocytozoon, offers a new tool to review the parasite specificity and status. by comparing morphological and genetic techniques, we observed nearly the same overall prevalence of haemos ...200818605786
