Under 900X magnification, this photomicrograph revealed the presence of an Entamoeba hartmanni microorganism at the cyst stage, in a specimen prepared using the Kohn staining method. In this focal plane you can see two distinct nuclei, each containing a single centrally located karyosome and a cigar-shaped, dark-colored chromatoid body. CDC/Dr Healy 1964

KENNEDY SPACE CENTER, FLA. - C. elegans nemotodes (round worms) undergo examination by project scientists. These specimens were found in a Biological Research in Canisters (BRIC) container, a middeck experiment that was among the Columbia debris recovered in East Texas. The worms are descendants of those that were part of an experiment that flew on Columbia's last mission, STS-107. The experiment was designed to verify a new synthetic nutrient solution for an International Space Station (ISS) "model" specimen planned to be used extensively for ISS gene expression studies and was sponsored by the NASA Ames Research Center. Scientists are now looking over the experiment at KSC to determine if it will yield any scientific results. The investigation into the cause of the Columbia accident is ongoing. (

This photomicrograph of a trichrome-stained specimen revealed the presence of a mononuclear cyst of Entamoeba hartmanni (arrow). The cysts of E. hartmanni are similar to those of E. histolytica, but smaller, measuring 5 to 10 m. Mature cysts contain four nuclei which have a small centrally located discrete karyosome and evenly distributed peripheral chromatin. Cysts may not be visible on unstained specimens. The cytoplasm of mature cysts may contain diffuse glycogen and rounded or elongated chromatoid bodies with rounded ends. CDC/Dr Mae Melvin 1977
