Description: English: ID#: 11649 Description: This digitally-colorized scanning electron micrograph (SEM) depicted the dorsal (upper) surface of a Giardia protozoan that had been isolated from a rat’s intestine. Some of the identifying morphologic characteristics include pairs of thread-like flagella that facilitate motility, and a ventolateral flange that appears as a “ruffle” around the anterior portion of the organism. Pairs of flagella seen here include an anterior, posterior-lateral, and caudal pairs. The protozoan Giardia causes the diarrheal disease called giardiasis. Giardia species exist as free-swimming (by means of flagella) trophozoites, and as egg-shaped cysts. It is the cystic stage, which facilitates the survival of these organisms under harsh environmental conditions. The cyst is considered the infective form, and disease is often transmitted by drinking contaminated water. As depicted in these SEMs, in the intestine, cysts are stimulated to liberate trophozoites. Cysts can be shed in fecal material, and can, thereafter, remain viable for several months in appropriate environmental conditions. Cysts can also be transferred directly from person-to-person, as a result of poor hygiene. Dr. Stan Erlandsen; Dr. Dennis Feely. Date: 1982.

Description: English: This digitally-colorized scanning electron micrograph (SEM) depicted a Giardia lamblia protozoan that was about to become two, separate organisms, as it was caught in a late stage of cell division, producing a heart-shaped form. The protozoan Giardia causes the diarrheal disease called giardiasis. Giardia species exist as free-swimming (by means of flagella) trophozoites, and as egg-shaped cysts. It is the cystic stage, which facilitates the survival of these organisms under harsh environmental conditions. The cyst is considered the infective form, and disease is often transmitted by drinking contaminated water. As depicted in these SEMs, in the intestine, cysts are stimulated to liberate trophozoites.

Description: English: This is a scanning electron micrograph (SEM) of an in vitro Giardia lamblia culture, which had been cultivated in bile-free TYI-S-33 medium for 48 hrs, then incubated 24 hrs with 10 mg/ml bovine bile in order to stimulate cyst formation. This photograph contains both trophozoites, and a cluster of maturing cysts (bottom right). At far left, the two trophozoite-staged organisms are positionally situated opposite to one another, with the farthest left G. lamblia displaying its dorsal, or upper surface, and the protozoan to its immediate right, its ventral, or bottom surface.
