Microbe vs. Mineral - A Life and Death Struggle in the Desert

Although the bursts of rainbow colors in this photograph are mesmerizing, microbes fight for their lives in the background. Chemist Michael P. Zach of the University of Wisconsin-Stevens Point, snapped this image of a salt sample he collected in a hot, arid valley near Death Valley National Park... Read More

Unknown Fungal Contaminant/MAC

Unknown fungal isolated contaminant found on MAC. MAC plate was incubated for 2 months at 4 degrees C once fungal growth was seen. This colony seemed to emerge from the agar and had a 3D appearance. The center of the colony had what seemed to be hyphal growth while the edges had a hard waxy un... Read More

Mycobacterium smegmatis Acid Fast Stain

Acid Fast stain done on a mix of Staphylococcus aureus and Mycobacterium smegmatis. Carbol fuchsin was applied to the smear and set over a steaming water bath for 10 min to help penetrate the mycolic acid in the cell wall, then rinsed with acid alcohol which washes the carbol fuchsin out of al...

Nematode Host Meets Bacterial Pathogen

This image shows the nematode host Caenorhbaditis elegans encountering the bacterial pathogen S. marcescens. Natural selection imposed by the co-evolving pathogen led to the evolution and maintenance of bi-parental sex in the host population.

The host and the pathogen were experimentally co-e... Read More

DNase Agar

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

microbes style

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

Fluid Thioglycollate Media

Organisms grown in Fluid Thioglycollate Media w/out resazurin dye is a reducing media that uses sodium thioglycollate to chemically combine with dissolved oxygen to deplete the oxygen in the media. All organism except for Neisseria sicca were grown for 48 hours at 37 degrees C. Neisseria sicca i... Read More
