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

Salmonella typhimurium

Under a magnification of 2500X, this colorized scanning electron micrograph (SEM) revealed the presence of a large number of Gram-negative Salmonella typhimurium bacteria that had been isolated from a pure culture. See PHIL 10984 for a black and white version of this image. Read More

Sporangiophore

Sporangiophore and columella of Mucor pusillus from culture. LCB stain 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

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

Treponema pallidum bacteria

An electron photomicrograph of two spiral-shaped Treponema pallidum bacteria.

Here we see two Treponema pallidum bacteria scanned by an electron microscope, magnified 36,000X. T. pallidum is the causative agent of syphilis. It contains one of the smallest prokaryotic genomes consisting of abo... Read More

The sporulating fungus, Beauveria Bassina, on TPB (Tarnished Plant Bug) cadaver.

Application of the mycopathogen, Beauveria Bassina, that make spores to introduce a fungus on tarnished plant bugs as an alternative to chemical control. Research and develop microbial control strategies for tarnished plant bugs on alternate hosts using entomopathogenic fungi.

Phomopsis Mold

Cultures of a destructive mold called Phomopsis strains that infect both crop and noncrop plants. One of the species of this genus, Phomopsis viticola, cause a plant disease called phomopsis or dead-arm. Usually, infections begin during early growth stages in spring. This affects leaves, fruit, ... Read More

Bacteria, protozoa, and algae from a wild stream

Under a moderately-high magnification of 2500X, 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 bacter...
