Transmission electron micrograph of the trophozoite,or proliferative form,of the sporozoan Toxoplasma gondii. Several organisms (large central ovals) are seen in liver tissue. 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.
