On the left is test isolate and on right side is positive control. Imipenem MIC by etest method was 0.75 ug/ml. How to interpret this modified hodge test; positive or negative? Read More
Cryptosporidium (Crypto) is a parasite that causes diarrheal disease. Crypto can live in the intestine of humans and animals and is passed in the stool of an infected person or animal. This parasite is very resistant to chlorine-based disinfectants and is protected by an outer shell that allows ... Read More
Colonies are initially black and yeast-like, becoming suede-like, olivaceous grey and mould-like with age. This photo show the morphology of colony after a week.

Kluyvera is a relatively newly described genus in the family Enterobacteriaceae that infrequently causes infections in humans. The organism has been isolated from various clinical specimens but its has been regarded alternatively as saprophytic, opportunistic, or pathogenic. In our case Kluyvera... Read More

Shown here is a bug that was sent for our lab for identification. It was identified as Cimex species, also known as the common bed bug. The two most common species that use humans as a host are C. lectularius and C. hemipterus. All adult and nymphal stages of this organism need to take blood mea... Read More
Growth Inhibition of Streptococcus pyogenes by Bacitracin. Streptococcus pyogenes is sensitive to bacitracin and will not grow around the antibiotic-containing disc. The other beta hemolytic streptococci are not sensitive to bacitracin. Isolated of Beatrice Rogolino M.Sc - photo Francesco d'Aleo... Read More
Growth of the gram negative bacteria Vibrio fischeri expressing bioluminescence as a result of the symbiotic interaction with Euprymna scolopes. You can see the plate without shining and glowing in the dark. The Form is the mascot of the University of Puerto Rico at Rio Piedras campus. Read More
Unknown airborne fungal isolated contaminant found on BEA. BEA plate was incubated for 2 months at 4 degrees C once fungal growth was seen. Spore formation can be seen throughout the circular colony. The single colony covered ¼ of the plate. Image highlights the center growth of the colony. Read More

Unknown airborne fungal isolated contaminant found on TSA. TSA plate was incubated for 2 months at 4 degrees C once fungal growth was seen. Concentric rings of color (pink, green and white) can be seen throughout the colony with smaller colonies seen around the white edges of the colony due to s... Read More
We all know about selfies, made popular by the camera in our cell phone. Well, here is the *real* deal - the 'cell-fie'. It's a photograph of my cell culture incubator full of stacks of plates in which HeLa cells are growing - and it's complete with my reflection. Read More
Fungal contaminant, presumably airborne, seen on a TSA plate after 1 month at refrigerated temperatures. Close up image highlights exudate, water droplets due to respiration. Read More
