Defining the rate-limiting processes of bacterial cytokinesis

This paper addresses some fundamental unanswered questions in microbiology: is the cytoskeletal cell division ring a major driving force for bacterial cytokinesis as it is for eukaryotes? If so, what is the mechanism? If not, what process is the major driving force? Read More

2 THINGS WE NEED TO FIGHT ZIKA’S EXPLOSIVE SPREAD

A recent outbreak of Zika virus in Brazil is causing alarm throughout the Americas, with health officials warning that the disease is “spreading explosively.” The World Health Organization (WHO) held an emergency meeting to address the problem, and the Centers for Disease Control and Prevention ...

HITTING INFECTIONS HARD CAN BE ‘THE WORST THING TO DO’

The standard practice of treating infections with the highest tolerable dose of antibiotic medications may not always be best way of preventing the evolution of drug resistance, a new study suggests. Read More

Alcaligenes faecalis line inoculation with swarming

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.

Pseudomonas aeruginosa with pigment

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

More Fungus

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

Mouse or monkey plate

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

Insect growth regulator wears a second hat: Infection fighter

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

ZIKA VIRUS ‘IS ABOUT AS SCARY AS IT GETS’

The Zika virus, unlike other mosquito-borne viruses such as dengue, has until now been relatively unknown and unstudied. Read More

Microbiology, Cartoons, and Take Home Lessons!

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

JAMA Viewpoint: Emerging Zika pandemic requires more WHO action now

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

New way to detect human-animal diseases tested in lemurs

DURHAM, N.C. -- Advances in genetic sequencing are uncovering emerging diseases in wildlife that other diagnostic tests can't detect. Read More

Immune response differences might determine severity of West Nile Virus disease

While most West Nile Virus (WNV) infections in humans are asymptomatic and go unnoticed, the virus causes serious and sometimes fatal neurologic illness in some people. A study published on January 21st in PLOS Pathogens suggests that an exaggerated and abnormal immune response contributes to th... Read More

GUT BACTERIA MAY BE BEST DEFENSE AGAINST NASTY GERMS

Antibiotic-resistant bacteria are on the rise, making it more and more difficult to treat infections. But research suggests that the best defense against harmful bugs could be a healthy population of “good” gut bacteria. Read More

TWiP 101: Is it round or is it flat?

The doctors TWiP solve the case of the Woman with White Worms, and explore the role of a secreted growth factor from a carcinogenic parasite in wound healing and angiogenesis.

The neurons in our gut help the immune system keep inflammation in check ROCKEFELLER UNIVERSITY

The immune system exercises constant vigilance to protect the body from external threats--including what we eat and drink. A careful balancing act plays out as digested food travels through the intestine. Immune cells must remain alert to protect against harmful pathogens like Salmonella, but th... Read More

Mushroom/Fungus #4

After several weeks of heavy rains several different mushroom species were seen in the leaf litter and shade of a pine tree in Santa Cruz, CA. The fungus was yellow/orange two toned color, slimy, and had an undulating appearance. Read More

Mushroom/Fungus #3

After several weeks of heavy rains several different mushroom species were seen in the leaf litter and shade of a pine tree in Santa Cruz, CA. The cap was greenish yellow with some orange, had a dull rough texture, was cone shaped (others had opened up and flattened out a bit more), gills were b... Read More

Mushroom/Fungus #2

After several weeks of heavy rains several different mushroom species were seen in the leaf litter and shade of a pine tree in Santa Cruz, CA. The cap was beige/tan, smooth and started to invert, gills were not attached to the stem. Read More

Unknown organism/Palm of hand print #2

Unknown organism, probable Bacillus spp, seen on palm of hand print done on MH, incubated at 37 degrees for 2 days, room temp for 3+ days then refrigerated temp for one month. Organism was beige, circular, mat towards the edges. The center was rhizoid/folded, hard to tell if there was fluid in ... Read More
