Microscopic Biological Samples

Close-up images of various microorganisms and cellular structures, revealing intricate details of parasites and mold growth in a scientific context.

This photomicrograph depicts an Entamoeba histolytica parasitic trophozoite, in which you can clearly see a single nucleus with its centrally placed karyosome, along with six ingested erythrocytes, or red blood cells (RBCs). CDC 1970

This photomicrograph of an iron-hematoxylin-stained specimen, revealed the presence of two amoebic organisms in their cystic stages of their development. In this focal plane, the smaller Entamoeba histolytica cyst (top), contained four nuclei, and two bluntly-tipped chromatoid bodies, while six nuclei could be detected in the larger Entamoeba coli cyst (bottom), which also contained two chromatoid bodies as well.

This scanning electron micrograph (SEM) depicts a Vibrio parahaemolyticus bacterium, Mag. 21851x. Vibrio parahaemolyticus is a bacterium in the same family as those that cause cholera. It lives in brackish saltwater, and causes gastrointestinal illness in humans. V. parahaemolyticus is a halophilic, or salt-requiring organism, naturally inhabiting coastal waters in the United States and Canada, and is present in higher concentrations during summer. When ingested, V. parahaemolyticus causes watery diarrhea often with abdominal cramping, nausea, vomiting fever and chills. Usually these symptoms occur within 24 hours of ingestion. Illness is usually self-limited and lasts 3 days. Severe disease is rare and occurs more commonly in persons with weakened immune systems.

Meningococcus or Neisseria meningitidis, is a bacterium that can cause meningitis. The bacteria are germs that can be found in the rhinopharynx, where it can cause benign rhinopharyngitis or an asymptomatic state. Only one in 400 carriers become victim to a serious meningococcal disease, mostly commonly acute purulent meningitis. Seen through an optical microscope X 1000.

This series of images shows carbon dioxide ice sublimating (going directly from a solid to a gas) inside a pit at Mars' south pole. As ice is lost from the steep walls of pits like this, it reforms on nearby flat surfaces. Each frame of the animation was taken by the High Resolution Imaging Science Experiment camera (HiRISE) on NASA's Mars Reconnaissance Orbiter. The images used in this animation were taken between 2007 and 2013. The walls of the pit are about 656 feet (200 meters) across. Animation available at

Numbers of Bacillus anthracis bacterial colonies, which had been allowed to grow on sheeps blood agar (SBA) for a 24 hour period. Note the classical appearance exhibited in the colonial morphology including a ground-glass, non-pigmented texture with accompanying comma projections from some of the individual rough-edged colonies. There is evidence that a tenacity test had been performed using an inoculating loop, which proved positive for B. anthracis, causing the colony to stand up like
