This scanning electron micrograph (SEM) depicted a number of red blood cells found enmeshed in a fibrinous matrix on the luminal surface of an indwelling vascular catheter, Magnified 7766x. In this instance, the indwelling catheter was a tube that was left in place creating a patent portal directly into a blood vessel. The erythrocyte in the center had undergone the process of crenation, whereupon, it developed a number of cell wall projections, thereby, transforming it into what is termed an acanthocyte, or spur cell.

Under a moderate magnification of 2000X, this digitally-colorized scanning electron micrograph (SEM) of an untreated water specimen extracted from a wild stream mainly used to control flooding during inclement weather, revealed the presence of unidentified organisms, which included bacteria, protozoa, and algae. In this particular view, a single copepod-like microorganism was seen occupying the field of view, which seemed to be encased in an outer shell of armour-like plates, or scales. Looking

Scanning electron micrograph of Ebola virus budding from the surface of a Vero cell (African green monkey kidney epithelial cell line. Produced by the National Institute of Allergy and Infectious Diseases (NIAID), under a very-high magnification, this digitally-colorized scanning electron micrograph (SEM) depicts a number of filamentous Ebola virus particles (red) that had budded from the surface of a VERO cell (blue-gray) of the African green monkey kidney epithelial cell line. Ebola hemorrhagic fever (Ebola HF) is one of Viral Hemorrhagic Fevers. It is a severe, often fatal disease in humans and nonhuman primates (such as monkeys, gorillas, and chimpanzees). Ebola HF is caused by infection with a virus of the family Filoviridae, genus Ebolavirus. When infection occurs, symptoms usually begin abruptly. The first Ebolavirus species was discovered in 1976 in what is now the Democratic Republic of the Congo near the Ebola River. Since then, outbreaks have appeared sporadically.

Scanning electron microscopy image illustrates tiny extracellular links between stereocilia of an inner ear hair cell. One type of link, the tip link, rests the top of the shorter stereocilia to the side of a longer stereocilia and is crucial for hearing. The yellow dots in the inset are the immuno-OR particles that label specific proteins comprising the spike binding.

Under a high magnification of 10,000x, this scanning electron micrograph (SEM) shows a strain of Staphylococcus aureus bacteria taken from a vancomycin intermediate resistant culture (VISA). Under SEM, one can not tell the difference between bacteria that are susceptible, or multidrug resistant, but with transmission electron microscopy (TEM), at least with VISA isolates one can see a thickening in the cell wall that may attribute to their reduced susceptibility to vancomycin. VISA and VRSA are specific types of antimicrobial-resistant staph bacteria. While most staph bacteria are susceptible to the antimicrobial agent vancomycin some have developed resistance. VISA and VRSA cannot be successfully treated with vancomycin because these organisms are no longer susceptibile to vancomycin. However, to date, all VISA and VRSA isolates have been susceptible to other Food and Drug Administration (FDA) approved drugs.

This illustration depicts a three-dimensional (3D) computer-generated image of a group of methicillin-resistant Staphylococcus aureus (MRSA) bacteria, which were arranged in a cluster. The artistic recreation was based upon scanning electron micrographic imagery. Methicillin-resistant Staphylococcus aureus (MRSA) causes a range of illnesses, from skin and wound infections to pneumonia and bloodstream infections that can cause sepsis and death. Staph bacteria, including MRSA, are one of the most common causes of healthcare-associated infections. Resistance to methicillin and related antibiotics (e.g., nafcillin, oxacillin) and resistance to cephalosporins are of concern. CDC estimates 80,461 invasive MRSA infections and 11,285 related deaths occurred in 2011. An unknown but much higher number of less severe infections occurred in both the community and in healthcare settings.
