Shown here is a picture of a hookworm egg found on a concentrate in an ova & parasite exam
Human hookworms include the nematode species, Ancylostoma duodenale and Necator americanus. These species have indistinguishable eggs and can only be distinguished by their larvae.
Infective larvae g... 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

Just when we think we know everything, a story comes along to remind us that there is something fundamental--and seemingly elementary--that we still haven't figured out. “Why are we the size we are? Why are our organs the size they are? Why are the cells in those organs a stereotypical size? Wha... Read More
A simple stain done on a stock culture of Aquaspirillum serpens to look at cell shape. This culture was grown in TSB at room temperature, ~21 degrees C, for several months. Aquaspirillum is a slow grower normally found in pond water. A characteristic spiral rod can be seen in the center of ... Read More
Organism seen on handprint, presumably Bacillus sp. Organism grew out from the center with rhizoid growth, lobate edges, tan coloration, glossy throughout the colony, Read More
We can see different biofilms types in liquid medium. In the same order than the picture: Methylobacterium variabile Type Strain / Methylobacterium aquaticum NO00 / Methylobacterium aquaticum NO42 / Methylobacterium aquaticum Type Strain / negative control Read More
Sammy Salmonella was created on a Muller Hinton Agar using three different isolates of Pseudomonas aeruginosa and Staphylococcus aureus for the outline. Pseudomonas aeruginosa is the only species of Pseudomonas that will produce pyocyanin, which is what creates Sammy’s green color. These bacte... Read More
This tree is made up of Streptococus pneumoniae (as the leaves)and Candida albicans (as the trunk),cultured on a chocolate agar incubated 24hours under 5% CO2 condition.
S.pneumoniae is a alpha hemolytic organism producing green colour colonies while C.albicans produce 'feet'around the margin o... 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
While not original art, it’s still a fun piece. BBL’s CHROMagar Orientation agar is the canvas for this piece of agar art. Chromogens in the agar release a colored compound when hydrolyzed by specific enzymes allowing certain bacteria to appear different colors on it. The brown color is Proteus... Read More
Helicobacter is a Gram-negative rod with a helical shape on gram stain. The most known strain is H. pylori, which causes ulcers and chronic gastritis and is said to affect up to 50% of the human population. This particular strain, Helicobacter fennelliae is most commonly found in the feces an... Read More
Cryptococcus cells seen with India Ink staining from CSF of an HIV patient in Tanzania. Taken using nothing more than a smartphone camera. The negatively stained capsule is clearly visible, proving that with very simple techniques and a cellphone you can get very clear images of microorganisms Read More
This is as portrait of the late Francis Crick created by my wife Dr. Jennifer Quinn using "paint" of luminous bacteria. Photobacterium leignothi was grown in LB amended to 20g/l NaCl for a few hours until visible luminescence was detected visually. The liquid culture was painted onto amended L... Read More

Serratia marcescens, Chromobacterium violeceum and Pseudomonas aeruginosa - what a romantic combination on Mueller Hinton II agar. All 3 organisms exhibit different pigment, Red, Purple and Green respectively on MHII agar, makes our daily routine of interpreting disk diffusion more interesting. Read More
Students in the summer STEM program at Cabrillo (these were college age students) were asked to do a handprint of their unwashed hand then of their hand after washing. This is a before and after of what the majority of the plates looked like. Plates were incubated for 48 hrs at 37 degrees C ... Read More
