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

The slide was prepared from blood of infected animals (cattle). The smear was stained with poly-chrome methylene blue which demonstrated blue colored bacillary body and light pink colored capsule (McFadyean's reaction).
The animal had the symptoms of high fever, convulsion and sudden death. ... 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

Unknown Fungal Contaminant found on TSA plate that had been refrigerated for 1 month. Colony was raised in the center with deep groves around the colony. Green spore formation was seen in the middle with white non-spore forming hyphae towards the edges. Read More
The Lyme disease spirochete, Borrelia burgdorferi, is an obligate parasite that cycles between ticks and vertebrate hosts. B. burgdorferi alters the proteins expressed on its outer surface, depending on the state of each host. Here, we used immunofluorescent antibodies to identify spirochetes th... Read More
Kluyvera is a relatively newly described genus in the family Enterobacteriaceae that infrequently causes infections in humans. The organism has been isolated from various clinical specimens but its has been regarded alternatively as saprophytic, opportunistic, or pathogenic. In our case Kluyvera... Read More

Some wild clones of social amoebas farm the bacteria they eat, but this is a losing strategy if nonfarming amoebas can steal the farmers’ crops. To make the strategy work, the farmers also carry bacteria that secrete chemicals that poison free riders. The work suggest farming is complex evolutio... Read More
Scientists have shown how a parasitic worm infection common in the developing world increases susceptibility to tuberculosis. The study demonstrated that treating the parasite reduces lung damage seen in mice that also are infected with tuberculosis, thereby eliminating the vulnerability to tube... Read More
Different view of Unknown Fungal contaminant on 7.5% NaCl BHI after several month at refrigerated temperatures. White hyphae was seen spreading into the agar with no spore formation. Read More
Bacteriophages were named because it appeared that the bacteria were being eaten by something. Here is a healthy E. coli strain (MG1655) that was mixed with a suspension of P1 phages and poured onto an agar plate. As the lawn of cells grew and covered the whole surface, plaques can be seen where... Read More
can u help me about this picture?
what's ur idea about this gram staining and arrangement?
in blood media alpha hemolysis has been seen so in macconkey agar have pink colony.
catalase + oxidase-
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.

As a microbiologist I wanted a keepsake footprint for my 3-month old daughter with a "personal touch"; while she was napping, I gently placed her foot on a horse blood agar plate. This just may be her first step into a future career in science, if not microbiology. Read More
Mapping deletion mutations by genetic tools is one thing, seeing them displayed along the length of a DNA molecule is quite another. But how can one see what isn’t there? In 1968, Ronald Davis and Norman Davidson did just that—visualizing deletion mutations in the genome of coliphage l. They rea... Read More
