onyx (sh) and Giardia intestinalis (medicine)


onyx (sh)




Striped, semiprecious variety of the silica mineral agate with white and black alternating bands.

Other varieties include carnelian onyx, with white and red bands, and sardonyx, with white and brown bands. Its properties are the same as those of quartz. Onyx is used in carved cameos and intaglios because its layers can be cut to show a colour contrast between the design and the background. It is found worldwide, but chiefly in India and South America.


Giardia intestinalis (medicine)


Giardia intestinalis -->
giardia lamblia


A species of parasitic protozoa that attaches itself to the intestinal mucosa and feeds on mucous secretions. The organism is roughly pear-shaped and motility is somewhat erratic, with a slow oscillation about the long axis. Considered for many years to be non-pathogenic and often found in completely asymptomatic individuals, there is presently strong evidence for its pathogenic potential.
