Caption: False-colour
transmission electron micrograph of the trophozoite, or proliferative
form, of the sporozoan Toxoplasma gondii. They appear as the large dark
stained bodies enclosing numerous organelles. T. gondii causes
toxoplasmosis in humans & is especially dangerous to pregnant women.
Cats are the definitive host and all mammals including sheep &
cattle may become infected. Only cats excrete the oocysts in their
faeces, which contaminate the soil & cause the infection in humans
& animals. Infection in man also occurs through undercooked meat, or
direct contact. Magnification: x3000 at 35mm size.
Lesson: Don't chill out with cats when they are taking a number two. (Or sheep).
But it is pretty to see magnified.
