 |
 |
| Cytospun pathogens after anaerobic co-culture with fecal bacteria (stool specimen was obtained from an asymptomatic individual) |
|
Key words : Blastocystis hominis, anerobic culture
|
 |
 |
|
| Cyst-forming microbes of varying sizes observed in the feces (Papanicolaou) | Cyst-forming microbes of varying sizes observed in the feces (Giemsa) | |

|
| Electron micrograph showing a cystic space and peripherally located round nucleus. Fine fibrillar mucoid matrix surrounds the microbe. | Rods are seen adjacent to the mitochondria-containing cystic microbe. The function of mitochondria in this obligate anaerobe remains mystery (electron micrograph). | |
