Cyanobacteria (Phormidium) with the vital stain Sytox Green. These cells are dead (green). White arrow shows other bacteria living in association with the cyanobacteria. Read More
This digitally-colorized scanning electron micrograph (SEM) depicted large numbers of Gram-positive Enterococcus sp. bacteria.
“Enterococci, leading causes of nosocomial bacteremia, surgical wound infection, and urinary tract infection, are becoming resistant to many and sometimes all standard ... Read More
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
This diagrams, as a trophozoite, the various forms that the developing malarial parasite undergoes prior to its schizont stage.
As the parasite increases in size, the ring morphology of the early trophozoite disappears, and becomes what is referred to as a mature trophozoite, which undergoes ... Read More
If the laboratory is not able to identify group-B streptococci (GBS) by the Lancefield grouping procedure, there are other microbiologic tests that can be used to identify GBS. This picture shows one of these tests. It is called the CAMP test. CAMP is an acronym for the authors of this test (Chr... Read More
This thin-section transmission electron micrograph (TEM) revealed the ultrastructural appearance of a single virus particle, or “virion”, of measles virus. The measles virus is a paramyxovirus, of the genus Morbillivirus. It is 100-200 nm in diameter, with a core of single-stranded RNA, and is c... Read More
This negatively-stained transmission electron micrograph (TEM) revealed the presence of Rubella virus virions, as they were in the process of budding from the host cell surface to be freed into the host’s system, thereby, producing an enveloped virus particle, which means that after budding, the...

Philadelphia artist Kate Kaman (www.katekaman.com) has designed a dynamic larger-than-life sculptural depiction of the most plentiful and ancient microscopic life forms -- bacteria. Suspended throughout an area measuring approximately 130 feet long, 27 feet wide and 41 feet tall, “The Unseen Wor... Read More
This photograph depicts the frontal view of a Petri dish within which fungal colonies of Trichophyton rubrum var. granulare had been cultured. Revealed is the colonial morphology, which in the case of T. rubrum is said to be waxy, glaborous, i.e., flat to cottony, and display from a frontal pers... Read More
Stained using a fluorescent antibody (FA) technique, this photomicrograph revealed a positive result for this stained serum specimen from a suspected rubella patient.
Rubella virus is classified as a togavirus, genus Rubivirus. It is most closely related to group A arboviruses, such as easter... Read More
This colorized scanning electron micrograph (SEM) depicted a flagellated Vibrio vulnificus bacterium; Mag. 26367x.
Vibrio vulnificus is a bacterium in the same family as those that cause cholera. It normally lives in warm seawater and is part of a group of vibrios that are called "halophilic"... Read More
The world’s first hard X-ray free-electron laser is taking remarkable “snapshots” of the inner life of proteins and viruses.
Two studies published in the journal Nature demonstrate the unique capabilities of the Linac Coherent Light Source (LCLS), located at the Department of Energy’s SLAC Na... Read More
An Ebola-like hemorrhagic fever has killed three people in western India and dozens of doctors will screen a community of about 16,000 people in efforts to contain the disease, a state health minister said this past Wednesday.
India's National Institute of Virology later confirmed that the th... Read More
This illustration depicts an Anopheles sp. mosquito transmitting sporozoites while obtaining a blood meal.
During a blood meal, a malaria-infected female Anopheles sp. mosquito inoculates its human host with sporozoites, which then infect human liver cells, where they mature into schizonts, w... Read More
Saturn’s moon Titan is wrapped in a thick, hazy atmosphere whose chemistry may mirror conditions on Earth before life emerged here some 4 billion years ago. In October Sarah Hörst reported that the resemblance is more than superficial. She simulated Titan’s haze in the lab and found it naturally... Read More
A particular type of ancient rock art in Western Australia maintains its vivid colours because it is alive, researchers have found.
While some rock art fades in hundreds of years, the "Bradshaw art" remains colourful after at least 40,000 years.
