Under a high magnification of 15549x, this colorized scanning electron micrograph (SEM) depicted some of the ultrastructural details seen in the cell wall configuration of a number of Gram-positive Mycobacterium tuberculosis bacteria. As an obligate aerobic organism M. tuberculosis can only surv... Read More
This negative stained transmission electron micrograph (TEM) shows recreated 1918 influenza virions that were collected from supernatants of 1918-infected Madin-Darby Canine Kidney (MDCK) cells cultures 18 hours after infection.
To separate these virions, the MDCK cells are spun down (centrif... Read More

A streak plate of Strep pyogenes on blood agar, stock culture used for class, was kept at room temp for 1 month. Before disposal a contaminant, presumably environmental, was seen on the plate. The pigment was opaque tan/yellow and with a mucoid surface. Lobate marigins with raised irregular-rh... Read More

This is a picture of a Gram stain of an anaerobic blood culture. This pleomorfic bacteria, were Gram negative filamentous bacilli with large round bodies. The identification by MALDI-TOF was Fusobacterium mortiferum. The patient has pancreatitis. I agree if you want to share this picture, since ... Read More
Streptococcus pneumoniae cells are Gram-positive, lancet-shaped cocci. Usually, they are seen as pairs of cocci, but they may also occur singly and in short chains. In this photo a mucoid strain on blood agar showing alpha hemolysis (green zone surrounding colonies). Note the zone of inhibition ... Read More
Streak plate of Streptococcus pyogenes (incubated @ 37 degrees C for 48 hrs) showing beta hemolysis, complete lysis of red blood cells, around the isolated colonies. Image taken using transmitted light. Read More
Strain: Pseudomonas aeruginosa PA14
Medium: M8 minimal medium agar plates
Incubation Conditions: 48 hours at 37°C
Pseudomonas aeruginosa is a gram-negative, rod-shaped and monoflagellated bacterium that has an incredible nutritional versatility. Swarming motility, a flagellum-dependent behavi... Read More
Seen here via immunohistochemical staining of a gastric biopsy is the Heliobacter Pylori bacteria, or H. Pylori if you're in a hurry.
Able to survive the intensely acidic environment that is the human stomach, H. Pylori actually gets downright comfortable there. The bacterium has flagella and... Read More
I just received a microscope the other day with a detachable USB camera! This is one of the first photos I took on it. Not the best as I'm still learning how to use it... but there are distinct Gram positive bacilli, cocci (diplococci I believe), and Gram negative bacilli from a finger inocula... Read More
