| immunological change in a parasite-impoverished environment: divergent signals from four island taxa. | dramatic declines of native hawaiian avifauna due to the human-mediated emergence of avian malaria and pox prompted an examination of whether island taxa share a common altered immunological signature, potentially driven by reduced genetic diversity and reduced exposure to parasites. we tested this hypothesis by characterizing parasite prevalence, genetic diversity and three measures of immune response in two recently-introduced species (neochmia temporalis and zosterops lateralis) and two islan ... | 2007 | 17878931 |
| morphological and molecular characterization of isospora neochmiae n. sp. in a captive-bred red-browed finch (neochmia temporalis) (latham, 1802). | a new isospora (apicomplexa: eimeriidae) species is described from a single red-browed finch (neochmia temporalis) (subspecies n. temporalis temporalis), that was part of a captive population in western australia. sporulated oocysts of this isolate are spherical, 18.3 (18.2-18.9) × 18.2 (18.2-18.6) μm, with a shape index (length/width) of 1.0; and a smooth and bilayered oocyst wall, 1.2 μm thick (outer layer 0.9 μm, inner 0.3 μm). a polar granule is present, but the oocyst residuum and a micropy ... | 2016 | 27107929 |
| establishing normal fecal flora in wild australian passerine birds by use of the fecal gram stain. | the purpose of this study was to determine the normal fecal bacterial and fungal flora and parasite prevalence in wild passerine birds found at the australian botanic garden (mount annan, new south wales). wild passerine birds (n = 186) from 28 species were captured with mist nets. fecal gram stains (n = 155) were made from 26 species and analyzed for bacterial density, gram stain morphology, and the presence of yeast. fecal wet preparations (n = 139) were made from 24 passerine species and were ... | 2017 | 28920776 |
