Slime production by Staphylococcus epidermidis on Congo Red agar; demonstrated by black colored colonies. Slime production is one of the most important virulence factors produced by Coagulase negative Staphylococci.
The colonies of slime non-producing strains remain pink to red.
This is a good news story all around. UC Berkeley engineers, Michael D'Amrosio and Matthew Bakalar (UC Berkeley Bioengineering) with medical personal from NIAID, Dr. Thomas Nutaman and his collaborators from Cameroon and France collectively took the omni-present global resource, a standard smar...

Streptomycetes are a member actinomycete family. Streptomycetes are usually found in soil and are important decomposers. They are aerobic, gram-positive, filamentous rods that create branching hyphae. They also produce more than half of the world's antibiotics, and are therefore very valuable in... Read More
This fungal colony, in association with a few others, was grown on SDA and appears to be an antibiotic producer. The compounds that it's producing appear orange and red. The colony grew and began producing compounds on the agar after five days incubation at 30 degree Celsius. This plate is part ... Read More
A sample of Proteus mirabilis was inoculated on to a TSA plate by taking a sterile swab and placing a drop in the center of the plate. The plate was then incubated at 37 degrees for 8 hrs. Swarming motility can be seen as a clear halo and finger like projections coming from and around the grow... Read More
Sometimes when a hairy beast of a contaminant grows on an old plate, the only thing to do is marvel at its beautiful rings and turn it into a cute cartoon. Any takers on the likely identity of this fungus? Read More
Paenibacillus species have been isolated from a wide variety of sources including soil, water, the plant rhizosphere, plant materials, food, fodder, faeces and diseased insect larvae. They are facultative anaerobes or strict aerobes and mostly motile, endospore forming rods. This is the first ti... 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
An international team of researchers has developed the largest genomic data set in the world on Lassa virus (LASV). The new genomic catalog contains nearly 200 viral genomes collected from patient samples in Sierra Leone and Nigeria, as well as field samples from the major animal reservoir, or h... 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
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
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
