| parasites from farmed ostriches (struthio camelus) and rheas (rhea americana) in europe. | during a 4-year-period, more than 500 ostriches and several rheas, all born in european countries and raised in spain and portugal, have been analyzed for the presence of ectoparasites and endoparasites. a total of 29 parasite species have been found, most of them of the gastrointestinal tract. some of the helminth species found may represent spureous parasitosis, as only the eggs (of an ascarid and a trematode) were found in some samples. from the organisms identified, the ectoparasites (lice-s ... | 2002 | 12072221 |
| further study of codiostomum struthionis (horst, 1885) railliet and henry, 1911 (nematoda, strongylidae) parasite of ostriches (struthio camelus linnaeus, 1758) (aves, struthioniformes). | codiostomum struthionis is a nematode parasite of the ostrich caecum. little is known about its pathology, being considered by many authors as a non-pathogenic parasite. infections by c. struthionis are sometimes overlooked because its eggs are indistinguishable from another ostrich nematode, libyostrongylus spp. fecal cultures and infective larvae identification are necessary for proper identification. the aim of this study is to provide improved morphological characterization of adults and inf ... | 2008 | 18774651 |
| pathological findings in the caeca of naturally infected ostriches, struthio camelus linnaeus, 1758 (aves, struthionidae) parasitized by codiostomum struthionis (horst, 1885) railliet and henry, 1911 (nematoda, strongylidae). | in order to characterize lesions associated with codiostomum struthionis in ostriches, 10 caeca were examined on both macro- and microscopic levels. parasites were found in the distal third of the caecum and characterized as c. struthionis. thickened mucosa was identified macroscopically where parasites were observed in high concentrations. nodular areas were also observed in the distal third of the infected caeca, as well as hemorrhagic areas abutting small ulcers surrounded by edema. these fin ... | 2009 | 19647369 |
| occurrence of nematodes and anthelmintic management of ostrich farms from different brazilian states: libyostrongylus douglassii dominates mixed infections. | ostriches were imported to brazil in the early 1990s without appropriate parasite control leading to a co-importation of parasites. libyostrongylus douglassii, libyostrongylus dentatus and codiostomum struthionis are nematodes of the ostriches that have been reported on some brazilian farms but no national survey has been performed. moreover, little is known about anthelmintic usage to control these parasites in brazil. therefore, the occurrence of l. douglassii, l. dentatus and c. struthionis a ... | 2010 | 21247703 |
| The occurrence of Codiostomum struthionis in ostriches (Struthio camelus) of different ages and during the dry and rainy seasons at two farms in the State of Rio de Janeiro, Brazil. | Ostriches are susceptible to a wide variety of diseases that can affect their commercial breeding. The aim of this study was to identify morphologically Codiostomum struthionis and examine its seasonal occurrence among animals of three age categories in two commercial farms in Areal and Itaboraí, State of Rio de Janeiro, Brazil. Fresh fecal samples were collected monthly, from June 2004 to May 2006. Eggs per gram of feces (EPG) were counted after centrifugal flotation in saturated sugar solution ... | 2012 | 21856078 |
