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
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
Bacteria adjust to wide fluctuations in food supply by controlling how big they get and how often they divide. Scientists at Washington University in St. Louis have just worked out the control system E. coli use to delay division so they can bulk up when food suddently becomes abundant. What can... Read More

Search and destroy! This image shows us how an immune cell, called a macrophage, attacks foreign bodies like bacteria – or this microbead – completely engulfing it so it can be broken down deep within the cell.

E. coli growth on EMB Agar. EMB Agar slightly inhibits gram-positive bacteria due to the combination of dyes and is a selective and differential medium for coliforms. Bacteria that ferments lactose will exhibit a green metallic sheen. This image represents E. coli as a quality control microorga... Read More

A new study led by researchers at the University of Minnesota has found a three-way link among antibiotic use in infants, changes in the gut bacteria, and disease later in life. The imbalances in gut microbes, called dysbiosis, have been tied to infectious diseases, allergies and other autoimmun... Read More

Unknown contaminant found on a TSA plate after being in the refrigerator for 1 month. Organism had grown throughout the media, was pale yellow and mucoid. 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
