Pictured here are blue colonies of Methicillin-resistant Staphylococcus aureus (MRSA) growing on Remel Spectra MRSA medium. Spectra media contains a chromogen that yields a blue color as a result of phosphatase activity. The phosphatase enzyme is present in many staphylococci, including Staphylo... 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
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
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
