A line inoculation was done with Alcaligenes faecalis and incubated for 48 hrs at 37 degree's C. Swarming/spreading could be seen form the inoculation line. Note: Small contaminate also seen on the plate.
A line inoculation was done with Pseudomonas aeruginosa. After 48 hrs incubation at 37 degrees C incubation the blue/green diffusible pigment pyocanin could be seen around the organism. There was also the characteristic grape smell. Read More
After several weeks of heavy rains several different mushroom species were seen in the leaf litter and shade of a cedar tree in Santa Cruz, CA. The fungus was yellow/orange, undulating appearance, with what looked like rough bumps on the outer edges with the inside being smooth. Read More
The rapid spread of Zika virus through the Americas, together with the association of infection with microcephaly and Guillain-Barré syndrome, have propelled this previously ignored virus into the limelight. What is this virus and where did it come from?
I was examining the anti microbial activity of a wound dressing material against a MRSA clinical isolate using a zone of inhibition assay. After incubation over night, I got some plates which have ZOIs in a shape of a mouse or money face. I attached an image. Read More
Why are obesity, juvenile diabetes and asthma increasing? Is it something in the environment or in our modern lifestyle? Dr. Martin Blaser thinks that it may be due to changes in our microbiome – the ecosystem of tiny microscopic creatures that live in and on us. Learn about his hypothesis th... Read More
During an animal's embryonic development, a chemical chain reaction known as Hippo directs organs to grow to just the right size and no larger. Now Johns Hopkins researchers working with laboratory flies report that this signaling pathway also plays a role in revving up the insects' immune syste... Read More
The Zika virus, unlike other mosquito-borne viruses such as dengue, has until now been relatively unknown and unstudied. Read More
News headlines highlighting an outbreak of a vaccine-preventable disease often leave readers shaking their heads. These diseases – measles, chickenpox, whooping cough – could have been prevented if only the infected children had been vaccinated. Right? Well, in the case of whooping cough, the si... Read More
In this blog post, I describe how I had students create their own cartoon depicting microbiological ideas and concepts that most tickled their fancy. I did this on their final exam, and the students came up with really interesting and entertaining ideas. IT's always interesting to see what stu... Read More
Washington, D.C.—January 26, 2016— Researchers have uncovered potent antimicrobial activity in a natural clay deposit found on the central coast of British Columbia, Canada. The research, published this week in mBio, an online open-access journal of the American Society for Microbiology, shows t... Read More
Washington, DC - January 25, 2016 - Nearly ten percent of cases of Staphylococcus aureus infections of the blood spread to the eyeball, according to a team of Korean clinical investigators. That spread can severely impair vision, and even cause blindness. The research was published January 11 in... Read More
WASHINGTON - The World Health Organization's Director-General should convene "urgently" a meeting of International Health Regulations' Emergency Committee to advise on the emerging Zika pandemic and galvanize global action, say two Georgetown University professors. Read More
DURHAM, N.C. -- Advances in genetic sequencing are uncovering emerging diseases in wildlife that other diagnostic tests can't detect. Read More
Near Kisameet Bay on the central coast of British Columbia sits a deposit of clay that covers 5 acres and spans a depth up to 42 feet in places. This vast smear formed 10,000 years ago as glacial melt filled a granite basin and fine minerals silted out.
The ancient clay likely holds secrets t... Read More
Ad hoc, uncoordinated and late. That’s how the UK government’s response to West Africa’s Ebola outbreak has been described in a report published on Monday by the House of Commons Science and Technology Select Committee.
The report calls for changes to enable the UK to identify threats earlier... Read More
Don’t get pregnant, at least for now. That is the chilling warning from governments battling the Zika pandemic, as evidence mounts that the mosquito-borne virus can cause severe birth defects.
As the scale of the impact starts to emerge, scientists are scrambling to learn more about the littl... Read More
“Good bacteria,” or probiotics, are everywhere these days, in pills and powders marketed as super supplements. Probiotics are said to improve digestive and immune health. They’re touted as potential treatments for conditions ranging from inflammatory bowel disease to eczema to tooth decay. Some ... Read More
Evolutionary theory predicts that pairs of chromosomes within asexual organisms will evolve independently of each other and become increasingly different over time in a phenomenon called the 'Meselson effect.' Researchers from the University of Glasgow have demonstrated the Meselson effect for t... Read More
