| redescription of flagellar arrangement in the duck intestinal flagellate, cochlosoma anatis and description of a new species, cochlosoma soricis n. sp. from shrews. | cochlosoma anatis kotlán (zoomastigophorea, retortamonadida, cochlosomidae), isolated from the large intestines of domestic rouen ducks, and cochlosoma soricis n. sp., isolated from the small intestines of shrews, were observed by light and scanning electron microscopy. in both organisms, a single flagellum inserted on the dorsal surface at the same level as the insertion of 4 other flagella on the ventral surface. the 4 ventro-lateral flagella emerged from the left side of the anterior attachme ... | 1989 | 2600878 |
| cochlosoma infection in a turkey in iran. | cochlosoma sp. infection was identified in a single case among 60 stunted diarrheic native turkey poults, meleagris galopavo. a large number of the flagellated parasites was found free or within the intervillous spaces of the jejunum, ileum and cecum. moderate enteritis was associated with the parasites. in tem studies of the parasagittal sections of the parasite, a prominent ventral sucker like disc and flagella emerging from an opening on the ventrodorsal surface of the pyriform uninuclear par ... | 2009 | 19967088 |
| identification of new morphological and life-cycle stages of cochlosoma anatis and experimental transmission using pseudocyst. | cochlosoma anatis is a flagellated intestinal parasite that infects a variety of avian species. c. anatis infections have been associated with decreased weight gain and increased morbidity and mortality. conditions favoring the growth of this organism in birds are current pathogenic intestinal infections and/or young age. there is little data describing the life cycle of this parasite. in this study, electron microscopy images are presented that document longitudinal binary fission of the tropho ... | 2006 | 16617976 |
| affiliation of cochlosoma to trichomonads confirmed by phylogenetic analysis of the small-subunit rrna gene and a new family concept of the order trichomonadida. | the protozoan genus cochlosoma includes parasitic intestinal flagellates of birds and mammals of uncertain taxonomic classification. the presence of an adhesive disc, superficially similar to that of giardia, led to a proposal that cochlosoma should be classified as diplomonads. careful morphological and ultrastructural observations, however, revealed conspicuous homologies to trichomonads. we addressed the question of classification and phylogenetic affiliation of cochlosoma using the methods o ... | 2006 | 16403903 |
| molecular assay for the detection of cochlosoma anatis in house flies and turkey specimens by polymerase chain reaction. | a 1520 bp region of cochlosoma anatis mtdna 16s gene was subjected to dna sequencing and a 466 bp portion was compared with other protozoan 16s sequences to develop pcr primers specific for c. anatis. this pcr diagnostic method allowed identification of c. anatis from house flies, musca domestica l., turkey gut, and fecal samples within 6 h after field-collected samples reached the laboratory. house flies detected carrying c. anatis using the diagnostic 374 bp amplicons represented the first rec ... | 2005 | 15631910 |
| experimental cochlosoma anatis infections in poultry. | cochlosoma anatis [kotlán, a., 1923. zentralbl. bakteriol. parasitenkd. infektienskr. hyg. 90, pp. 24-28] is a flagellated protozoan parasite of birds. we have encountered c. anatis in turkeys with enteritis. experimental oral inoculations of turkeys with 1 x 10(6) to 10 x 10(6) trophozoites consistently reproduced infections in recipients. trophozoites were most numerous in the jejunum and ileum but could be observed in the duodenum, ceca, colon, and feces. when 12 naive turkeys were placed on ... | 1999 | 9950325 |

| effects of the intestinal flagellate, cochlosoma anatis, on intestinal mucosal morphology and disaccharidase activity in muscovy ducklings. | newly hatched female muscovy ducklings were randomly separated into 2 groups of 12 and 1 group of 13. ducklings in the first 2 groups were each orally inoculated with 0.5 ml of sterile normal saline containing 0 and 3 x 10(6) trophozoites of cochlosoma anatis, respectively. birds in the third group were each orally inoculated with 3 x 10(6) trophozoites for 5 consecutive days. birds were weighed daily for the first 5 days and then on days 7, 14 and 21 post-inoculation (p.i.). on days 6, 7, 8, 13 ... | 1996 | 8818734 |
| runting of ducklings associated with cochlosoma anatis infection. | ducklings, especially common goldeneye (bucephala clangula), experiencing poor weight gain and delayed development were reported from a waterfowl park during june and july of 1990. runting was first noticed between days 5 and 10 post-hatch in the "brooder" building, and although ducklings appeared active and were feeding, they developed at a slower rate than other members of their clutch. many ultimately died of emaciation and gram-negative bacterial septicemia. necropsies of affected ducklings ... | 1996 | 8713032 |
| enteritis in turkeys associated with an unusual flagellated protozoan (cochlosoma anatis). | outbreaks of enteritis associated with an unusual flagellated protozoan occurred in six california turkey flocks during the summer of 1992. certain morphological and ultrastructural details of the parasite, which resembles cochlosoma anatis, are illustrated with scanning and transmission electron micrographs. the flagellate attached to the intestinal mucosa by means of a sucker-like apparatus, and circular impressions of the sucker were created on the surface epithelium. histological lesions wer ... | 1995 | 7794181 |
