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

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
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 fungal contaminant seen on Casein media after 1 month at refrigerated temperatures. Green spore formation is seen throughout the colony with white hyphal growth on the outer edge of the colony. The center was raised and had deep groves. 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
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
Typical bed bug bite pattern, 3-5 bites clustered in a zigzag pattern also know as the breakfast, lunch, dinner pattern. Image taken 5 days after exposure. Read More
Salmonella is a zoonotic foodborne pathogen and a public health concern. It has been estimated that this pathogen causes ~1.2 million illnesses, ~20,000 hospitalizations, and ~400 deaths in the US annually (Scallan et al., 2011). Salmonella has ~2,600 serotypes (serovars) and numerous hosts and ... Read More
