Rotavirus

Note the wheel-like appearance of some of the rotavirus particles. The observance of such particles gave the virus its name ('rota' being the Latin word meaning wheel). Bar = 100 nanometers. Rotaviruses are nonenveloped, double-shelled viruses, making the virus stable in the environment.

Scanning electron microscopy of Staphylococcus epidermidis cluster embedded in exopolysaccharide matrix

The Gram-positive bacteria Staphylococcus epidermidis and Staphylococcus aureus are the most common pathogens in hospital-acquired infections. The costs related to infections caused by these strains in the hospital setting are enormous and represent a major healthcare burden. Furthermore, the mo... Read More

Micrococcus luteus

Under a high magnification of 21930x, this scanning electron micrograph (SEM) depicted some of the ultrastructural morphologic features displayed by this group of Gram-positive Micrococcus luteus bacteria. The specimen was obtained from a pure culture that was raised on a polycarbonate filter, f... Read More

Tissue specimen showing spirochete

Tissue specimen showing spirochete (Treponema pallidum) (970X). Taken from the Wistriech Collection, appearing exclusively on MicrobeWorld. Read More

Parasitic Fungus Phragmidium tuberculatum on a rose leaf

Colorized scanning electron micrograph of rust on a rose leaf. Rose rust is a disease specific to roses and is caused by the parasitic fungus Phragmidium tuberculatum and some other closely related species. This disease occurs during spring and persists until the leaves fall. This images shows r... Read More

Diatom Arachnoidiscus

This is a live image of the of Diatom Arachnoidiscus under 40x magnification. The picture shows the diatom's silicified cell wall, which forms a pillbox-like shell (frustule) composed of overlapping halves that contain intricate and delicate markings. The picture was obtained with new video enha... Read More

Chlamydia trachomatis

Photomicrograph of Chlamydia grown in culture. The sample was taken from rhesus monkey kidney cells and stained with giemsa. The cell nuclei appear red and the infective 'elementary bodies' of the Chlamydia, which develop in 'blisters' in the cells, fluoresce green. Chlamydia is a very common se... Read More

USA300 strain of S. aureus

The USA300 strain of Staphylococcus aureus bacteria, colorized in gold, shown outside a white blood cell.

Staphylococcus aureus: USA:300 is a strain of gram-positive coccus bacteria responsible for Methicillin-resistant Staphylococcus aureus (MRSA), or Staph infection in humans. This strain ... Read More

Cultured cells

This image of laboratory-grown cells was taken with the help of a scanning electron microscope, which yields detailed images of cell surfaces.
