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… 
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 and phylogenetic affiliation and is addressed using the methods of molecular phylogenetics.
Identification of New Morphological and Life-Cycle Stages of Cochlosoma anatis and Experimental Transmission Using Pseudocyst
Abstract 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
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, and Cochlosoma anatis is associated with the runting syndrome observed in ducklings.
Cochlosoma infections in finches.
Cochlosoma anatis-like organisms can infect several species of finches and in adult finches are confined to the colorectum and cloaca and could be treated effectively with metronidazole or ronidazoles.


A new liquid medium for xenic cultivation of Entamoeba histolytica and other lumen-dwelling protozoa.
A new liquid medium, TYSGM-9, devised to facilitate the transition of Entamoeba histolytica from xenic to axenic conditions of growth has proved valuable for initiation and maintenance of cultures of the following protozoa inhabiting the intestine or mouth of man.
Ultrastructural evidence for the presence of bacteria, viral-like particles, and mycoplasma-like organisms associated with Giardia spp.
Giardia trophozoites and cysts, isolated from mammalian and avian hosts, were examined by transmission electron microscopy (TEM), scanning electron microscopy (SEM), and by fluorescent light
Axenic culture of Giardia lamblia in TYI-S-33 medium supplemented with bile.

A fixative for intestinal parasites permitting the use of concentration and permanent staining procedures.
Results obtained with stools preserved in a simple, stable and relatively nontoxic fixative (SAF) composed of sodium acetate, acetic acid and formalin, suggest that this fixative is a suitable
