| 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 |
| 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 |
| disseminated visceral coccidiosis in whooping cranes. | three 13- to 18-day-old whooping cranes (grus americana) and a 9-year-old whooping crane died in outdoor pens at the patuxent wildlife research center. the deaths were associated with an overwhelming systemic infection by an intracellular protozoan parasite, which resulted in enteritis, granulomatous bronchopneumonia, hepatitis, splenitis, and myocarditis. the clinical, histopathologic, and electron microscopic findings were similar to those in sandhill cranes (grus canadensis) at the patuxent c ... | 1980 | 7451323 |
| pulmonary lesions in disseminated visceral coccidiosis of sandhill and whooping cranes. | fifty cranes, consisting of 46 sandhill (grus canadensis) and four whooping cranes (grus americana), were studied. eighteen sandhill cranes and the four whooping cranes were naturally infected with disseminated visceral coccidiosis (dvc). the remaining sandhill cranes were chicks experimentally infected with oocysts of eimeria reichenowi and/or e. gruis; five chicks served as controls. there were no clinical signs attributed to respiratory infection. necropsy of naturally infected adult birds re ... | 1989 | 2810553 |
| survey of coccidial oocysts and parasite eggs in feces of free-ranging grus japonensis. | fecal survey of eimeria oocysts and parasite eggs was conducted for 219 fecal samples of free-ranging grus japonensis in kushiro district in hokkaido in april 2003. positive rate and mean oocysts (or eggs) per gram in positive samples were 26% (57/219) and 8.8 (0.2-136) in oocysts of eimeria reichenowi, 18.3% (40/219) and 320 (100-1,000) in trematode eggs, 0.1% (2/219) and 0.2 (0.2-0.3) in eggs of nematoda a, and 4.1% (9/219) and 0.8 (0.2-3.6) in eggs of nematoda b, respectively. | 2006 | 16953091 |
| disseminated visceral coccidiosis in eurasian cranes (grus grus) in the uk. | clinical disease and mortalities due to disseminated visceral coccidiosis were identified for the first time in a group of captive juvenile eurasian cranes (grus grus) in the uk during 2008. presumptive diagnosis was made from the finding of granulomatous nodules in the liver, spleen and other organs at gross postmortem examination, and confirmed histologically by the presence of intracellular coccidial stages within lesions. the species of coccidian was determined to be eimeria reichenowi on th ... | 2011 | 21493556 |
| identification of a novel renal coccidian (apicomplexa: eimeriidae) from the great-horned owl ( bubo virginianus ), usa. | we diagnosed renal coccidiosis in two of five great-horned owls ( bubo virginianus ) examined in eastern tennessee, us, 2007-13. histopathologic examination of the kidneys revealed multifocal mild-to-moderate dilation and epithelial hyperplasia of collecting ducts. renal collecting duct epithelial cells contained intracytoplasmic microgametocytes, macrogametocytes, and sporulating and sporulated oocysts. renal coccidiosis in affected birds did not result in significant inflammation. sequence ana ... | 2017 | 28139953 |
| 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 |
| 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 |
