Three-dimensional fine structure of feeder organelle in Cryptosporidium parvum.

Summary of "Three-dimensional fine structure of feeder organelle in Cryptosporidium parvum."

Feeder organelles of Cryptosporidium are the convoluted structures located at the host-parasite interface that uptake of nutrients from host cells. Although the ultrastructure of feeder organelles has been summarized as being highly invaginated structure, the three-dimensional form remains uncertain. Osmium-maceration scanning electron microscopy (OS-SEM) allows visualization of the three-dimensional ultrastructure after removing soluble proteins. Here, we assessed C. parvum attached to mouse ileal epithelial cells using transmission electron microscopy (TEM) and OS-SEM. Feeder organelles visualized by TEM as aggregated structures of concentrically-, vertically- and randomly-lined bars comprised a complex reticulated network of stacked flat bursiform, ring-shaped bursiform and reticulated tubular membranes on OS-SEM. These findings suggested that the feeder organelles are more complex than was previously thought.

Medical and Biotech [MESH] Definitions

A species of parasitic protozoa that infects humans and most domestic mammals. Its oocysts measure five microns in diameter. These organisms exhibit alternating cycles of sexual and asexual reproduction.

Cells used in COCULTURE TECHNIQUES which support the growth of the other cells in the culture. Feeder cells provide auxillary substances including attachment substrates, nutrients, or other factors that are needed for growth in culture.

Using fine needles (finer than 22-gauge) to remove tissue or fluid specimens from the living body for examination in the pathology laboratory and for disease diagnosis.

Echocardiography amplified by the addition of depth to the conventional two-dimensional ECHOCARDIOGRAPHY visualizing only the length and width of the heart. Three-dimensional ultrasound imaging was first described in 1961 but its application to echocardiography did not take place until 1974. (Mayo Clin Proc 1993;68:221-40)

The process of generating three-dimensional images by electronic, photographic, or other methods. For example, three-dimensional images can be generated by assembling multiple tomographic images with the aid of a computer, while photographic 3-D images (HOLOGRAPHY) can be made by exposing film to the interference pattern created when two laser light sources shine on an object.
