Please help me! I am planning to identify this microorganism by API but I can not identify the shape (rod or cocci). This microorganism has positive oxidase. Its colony is red, irregular, flat.
Please teach me. Thanks so much! Nhu Thuy from Vietnam
This is an 3D image of conidiophores of the filamentous fungus Neurospora crassa. Conidiophores are hyphae which differentiate to produce asexual structures named spores or conidia. The image taken using a confocal microscope shows conidiophores stained with a fluorophore which stains components... Read More

Isolated colony of Mycobacterium smegmatis grown on TSA for 96 hrs at 37 degrees C. Margin is lobate with an irregular-rhizoid form. Image taken using transmitted light. Read More
When the Ebola virus outbreak erupted in West Africa in 2014, children infected with the virus -- particularly those under age 5 -- faced overwhelming challenges. Not only was there a high death rate among young children infected with the disease, they often were isolated from their families, le... Read More
This cutely radish photo of the colony of Aspergillus niger was taken by a digital camera. Before that Aspergillus niger was grown on SDA (Saboraud Dextrose Agar) media for the research purpose of testing antifungal activity of Scallop Powder(SP). SP ,a natural source obtained from Bivalves, can... Read More
Sammy Salmonella was created on a Muller Hinton Agar using three different isolates of Pseudomonas aeruginosa and Staphylococcus aureus for the outline. Pseudomonas aeruginosa is the only species of Pseudomonas that will produce pyocyanin, which is what creates Sammy’s green color. These bacte... Read More
Our sensitivity instruments rarely ever go down, but when they do our lab uses Kirby-Bauer testing to perform antimicrobial susceptibility testing in our laboratory. This testing involves placing antibiotic-infused discs on a standardized inoculum of bacteria spread in a lawn onto a Mueller Hint... Read More
Researchers at University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences have found that the breast cancer drug tamoxifen gives white blood cells a boost, better enabling them to respond to, ensnare and kill bacteria in laboratory experiment...

An experimental vaccine to protect against the mosquito-borne illness chikungunya is being tested in a Phase 2 trial sponsored by the National Institutes of Health. Results from an initial trial of the vaccine, which was developed by scientists at the NIH National Institute of Allergy and Infect... Read More
A gene that lets bacteria resist polymyxins—the last line of antibiotic defense we have left—has shown up in widespread bacteria samples from pigs and patients in south China, including strains with epidemic potential. Read More

Baker's yeast cells living together in communities help feed each other, but leave incomers from the same species to die from starvation, according to new research from the University of Cambridge. 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
Three organisms inoculated onto blood agar, straight line inoculation, to demonstrate hemolysis. From top to bottom:
Streptococcus pyogenes: beta, complete lysis of red blood cells, clear area around colony growth.
Streptococcus bovis: alpha, incomplete lysis of red blood cells, green area ... Read More
This strain of Pseudomonas aeruginosa isolated from wound make a green pigment: pyoverdine. Pyoverdine is a fluorescent siderophores for to acquire iron.
Pyoverdine biosynthesis in Pseudomonas aeruginosa and fluorescent Pseudomonads is a complex process.

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
