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
In this blog post, I discuss our Summer Research Program's "Lab Themed Dessert" competion, for which one of my students created a cake "sculpture" of Bdellovibrio attacking and invading E. coli. It was tasty, informative, and fun! My student clearly thought about Bdellovibrio a LOT during the ... Read More
Hi, I am doing a research in Cryptosporidium parvum and Cyclospora cayetanensis infection among School children of kathmandu at Public health research laboratory, the Institute of Medicne, kathmandu.
This is a Modified ZN stained image of Cyclospora cayetanensis isolated form a 5 year School... Read More
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

Another major goal of synthetic biology is to engineer unnatural molecules and compounds into systems and tools that mimic those found in biology. For instance, Joanna Aizenberg and her laboratory have pioneered using self-assembling synthetic nanofibers to generate capture-and-release devices t... 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

Growth Inhibition of Streptococcus pyogenes by Bacitracin. Streptococcus pyogenes is sensitive to bacitracin and will not grow around the antibiotic-containing disc. The other beta hemolytic streptococci are not sensitive to bacitracin. Isolated of Beatrice Rogolino M.Sc - photo Francesco d'Aleo... Read More

In a new study, researchers demonstrate for the first time how methanogens obtain electrons from solid surfaces. The discovery could help scientists design electrodes for microbial “factories” that produce methane gas and other compounds sustainably. Read More
Casein Plates contain the major milk protein found in milk. Organisms were grown on Casien agar for 72 hours at 37o C to look for the presence of the exoenzyme proteases/caseases . (A): Pseudomonas aeruginosa, casein hydrolysis, as noted by a zone of clearing around the organism, as well as a ... Read More
Contrary to current medical dogma, researchers at University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences report that the common antibiotic azithromycin kills many multidrug-resistant bacteria very effectively -- when tested under conditio...

This blog post describes a "video meeting" between Seth Bordenstein and my freshman writing class in the Fall of 2014. My freshman class revolved around ideas in symbioses and parasitism, so Seth's ideas regarding holobionts and the hologenome were particularly apt. Furthermore, last week Seth... 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
