| use of monoclonal antibodies against chicken coccidia to study invasion and early development of eimeria gruis in the florida sandhill crane (grus canadensis). | eimeria gruis and e. reichenowi are common coccidial parasites of a number of crane species. in the present study, monoclonal antibodies (mcabs), elicited against eimeria spp. of chickens and turkeys, cross-reacted with sporozoites and developmental stages of e. gruis in the tissues of florida sandhill cranes. these mcabs were used to define the area of the intestine that was invaded by sporozoites of e. gruis and to demonstrate the feasibility of using mcabs to study the early development of e. ... | 1998 | 9638620 |
| pathology and pathogenesis of disseminated visceral coccidiosis in cranes. | disseminated visceral coccidiosis (dvc) caused by eimeria spp. was recognized as a disease entity in captive sandhill cranes (grus canadensis) and whooping cranes (grus americana) in the late 1970s. while most avian species of eimeria inhabit the intestinal tract of its host, the crane eimerians, eimeria reichenowi and eimeria gruis, invade and multiply systemically and complete their development in both digestive and respiratory tracts. in dvc, cranes, especially chicks, may succumb to acute in ... | 2004 | 15223553 |
| coccidia of sandhill cranes, grus canadensis. | eimeria gruis yakinoff and matschoulsky 1935, eimeria reichenowi yakimoff and matschoulsky 1935, and an adelina species are described from sandhill cranes in the united states. e. gruis was found in the feces of 11 of 14 florida sandhill cranes (grus canadensis pratensis) and 62 of 72 greater sandhill cranes (g. c. tabida) from florida, 5 of 14 greater sandhill cranes from arizona, and 4 of 16 lesser sandhill cranes (g. c. canadensis) from texas. e. reichenowi was found in the feces of 12 of 14 ... | 1975 | 809566 |
| coccidia of whooping cranes. | coccidial oocysts were observed in 6 of 19 fecal samples from free-ranging whooping cranes (grus americana) and 4 of 16 samples from captive whooping cranes. eimeria gruis occurred in four free-ranging whooping cranes and e. reichenowi in two free-ranging and two captive whooping cranes. fecal samples from two captive cranes contained oocysts of isospora lacazei which was considered a spurious parasite. oocysts of both species of eimeria were prevalent in fecal samples collected from three free- ... | 1978 | 633514 |
| molecular characterization of crane coccidia, eimeria gruis and e. reichenowi, found in feces of migratory cranes. | eimeria gruis and e. reichenowi have lethal pathogenicity to a number of species of cranes. these parasites develop at multiple organs or tissues in infected cranes, thus lacking the specificity of infection sites shown by other eimeria spp. in spite of morphologic similarity. to date, there have been many reports of crane eimeria infections, however, genetic examinations of these parasites have never been published. in the present study, we isolated oocysts of e. gruis and e. reichenowi from cr ... | 2005 | 15940517 |
| genetical identification of coccidia in red-crowned crane, grus japonensis. | we genetically analyzed eimerian oocysts isolated from the red-crowned crane (grus japonensis) in hokkaido, a northern island of japan. two types of oocysts of which shapes were similar to eimeria gruis and e. reichenowi were found. nearly the total length of the 18s ribosomal rna gene (about 1.7 kbp in length) was amplified from single oocyst of each type and was sequenced. the respective sequences showed high similarity to those of published partial sequences (349 bp) of e. gruis type oocyst a ... | 2007 | 17102986 |
| use of monoclonal antibodies developed against chicken coccidia (eimeria) to study invasion and development of eimeria reichenowi in florida sandhill cranes (grus canadensis). | eimeria gruis and eimeria reichenowi are common coccidial parasites of a number of species of cranes. until recently, little was known about either the site for invasion or the dynamics of early development of the crane coccidia because of the difficulty of identifying sporozoites and early developmental stages of these parasites by conventional staining methods. in the present study, monoclonal antibodies (mabs) elicited against eimeria spp. of chickens and turkeys were found to cross-react wit ... | 2001 | 12790396 |
| accurate analysis of prevalence of coccidiosis in individually identified wild cranes in inhabiting and migrating populations in japan. | eimeria gruis and e. reichenowi cause coccidiosis, a major parasitic disease of cranes. by non-invasive molecular approaches, we investigated the prevalence and genetic characterization of pathogens in two japanese crane habitats; one is hokkaido inhabited by the endangered red-crowned crane, and the other is izumi in kyushu where populations that consist mainly of vulnerable hooded and white-naped cranes migrate in winter. the non-invasively collected faecal samples from each wintering populati ... | 2011 | 21895916 |
| morphological and molecular characterization of eimeria paludosa coccidian parasite (apicomplexa:eimeriidae) in a dusky moorhen (gallinula tenebrosa, gould, 1846) in australia. | an eimeria species is described from a dusky moorhen (gallinula tenebrosa). sporulated oocysts (n = 40) are ovoid, with a pitted single-layered oocyst wall in young oocysts and a relatively smooth wall in the mature oocysts. oocyst wall was 1.0 µm thick, oocysts measured 17.3 × 13.3 (16.3-17.9 × 12.7-13.9) µm, oocyst length/width (l/w) ratio, 1.3. oocyst residuum was absent. a large polar granule was always observed in the centre of the micropyle and many small polar granules were observed when ... | 2014 | 25448356 |
| coccidian parasites and conservation implications for the endangered whooping crane (grus americana). | while the population of endangered whooping cranes (grus americana) has grown from 15 individuals in 1941 to an estimated 304 birds today, the population growth is not sufficient to support a down-listing of the species to threatened status. the degree to which disease may be limiting the population growth of whooping cranes is unknown. one disease of potential concern is caused by two crane-associated eimeria species: eimeria gruis and e. reichenowi. unlike most species of eimeria, which are lo ... | 2015 | 26061631 |
| survey of gross and histopathologic findings in two wintering subpopulations of sandhill cranes ( antigone canadensis). | : sandhill cranes ( antigone canadensis) of the midcontinent population (mcp) and rocky mountain population (rmp) are migratory game birds with stable populations that travel between canada and the southern us and mexico. in the winters of 2012-14, we performed gross and histologic examinations of 43 hunter-harvested sandhill cranes in texas (mcp) and new mexico (rmp) to assess the impact of disease on populations. lesions were significantly more common in the mcp relative to the rmp, likely re ... | 2018 | 29053431 |
