A microorganism (from the Greek: μικρός, mikros, "small" and ὀργανισμός, organismós, "organism") is a microscopic organism, which may be a single cell or multicellular organism. The study of microorganisms is called microbiology, a subject that began with Antonie van Leeuwenhoek's discovery of m... Read More
Spiroplasmas are bacteria in the Class Mollicutes that are frequently associated with insects and/or plants. This confocal laser scanning micrographs show aggregates of symbiotic/ commensal spiroplasma-like organisms (SLOs) in the midgut (mg) and filter chamber (fc) of a leafhopper, Dalbulus mai...

DNase agar can be used to differentiate between potentially pathogenic S. aureus and other Staphlococcus by looking for the presense of the exoenzyeme DNase. After growth for 24-48 hrs 1N HCL is added to the agar plate. Addition of HCL precipitates DNA in the media causing cloudiness unless t... Read More

It causes human mucormycosis and bovine mycotic abortion.
It is distinguished from R.arrhizus by its shorter stalk, and smaller sporangia and spores.
Var.oligosporus : has elongated columellae ; spores less obviously striated.
Var.rhizopodiformis : has ... Read More
I'm a micro newbie! I just finished school this year! I grew this in my final clinical rotation and I thought it was beautiful! Read More
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
Wouldn’t you be tempted to attend such a session if it were part of a current-day ASM meeting? The first five papers ever delivered to a meeting of the Society of American Bacteriologist (now the ASM) are so utterly relevant to our concerns that they could be delivered now. No changes to the ti... Read More
The spherical spores produced by the fungus Emericella nidulans are coated in a thin layer of the protein hydrophobin. Hydrophobin ensures that water rolls off the spores. Other fungi, such as mushrooms, also have a layer of hydrophobin on their caps. BASF researchers have succeeded in transferr... Read More
This is a slime mold by the name of Physarum polycephalum. Part of him crept out of the petri dish that had been mistakenly written on with a blue wet erase marker. During growth, I wrap these plates up in foil because the slime mold needs complete darkness to grow. The foil and the humidity ... Read More
