Plague infections were common in humans 3,300 years earlier than the historical record suggests, reports a study published October 22 in Cell. By sequencing the DNA of tooth samples from Bronze Age individuals from Europe and Asia, the researchers discovered evidence of plague infections roughly... Read More
I did a study of hand washing and hand sanitizer. Is anyone on the list willing to help me identify what grew from my unwashed and even washed hands? I attach three photos representing the yellow, white and orange growths found after several days on agar plates. Thank you so much in advance. Read More
DURHAM, N.C. -- Many bugs that make us sick -- bacteria, viruses, fungi and parasites -- hide out in our cells in protective little bubbles called vacuoles. To clear an infection, the immune system must recognize and destroy these vacuoles while leaving the rest of the living cell intact. Read More
Scientists at the National Institutes of Health (NIH) have created a protein that awakens resting immune cells infected with HIV and facilitates their destruction in laboratory studies. The protein potentially could contribute to a cure for HIV infection by helping deplete the reservoir of long-... Read More
There is currently no approved specific treatment or vaccine for dengue fever, and an estimated 2 billion people are at risk for being bitten by Aedes mosquitoes and infected with the dengue virus (DENV). A study published on October 22nd in PLOS Pathogens introduces a candidate target for a tra... Read More
Influenza is known as an infectious respiratory disease, but a study published on October 8th in PLOS Pathogens suggests that infected cells in breast tissues could play a role in virus transmission from mothers to breast-feeding infants and vice versa using a ferret model. Read More
White-nose syndrome (WNS), an invasive skin infection caused by the Pseudogymnoascus destructans (Pd) fungus has killed millions of bats since it was first seen in North America in 2007. A analysis of gene expression in hibernating bats infected with the destructive fungus published on October 1... Read More
Swab taken from the lab table top and incubated on TSA for 48 hrs, left at room temperature for 72 hrs then held at refrigerated temperature for a month. Pictured is one of the resulting fungal growths: white with no spore formation, droplets can be seen as possible result of respiration. Read More
This strain of Pseudomonas aeruginosa isolated from wound make a green pigment: pyoverdine. Pyoverdine is a fluorescent siderophores for to acquire iron.
Pyoverdine biosynthesis in Pseudomonas aeruginosa and fluorescent Pseudomonads is a complex process.

When the Ebola virus outbreak erupted in West Africa in 2014, children infected with the virus -- particularly those under age 5 -- faced overwhelming challenges. Not only was there a high death rate among young children infected with the disease, they often were isolated from their families, le... Read More
Baker's yeast cells living together in communities help feed each other, but leave incomers from the same species to die from starvation, according to new research from the University of Cambridge. Read More
Researchers at University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences have found that the breast cancer drug tamoxifen gives white blood cells a boost, better enabling them to respond to, ensnare and kill bacteria in laboratory experiment...

A gene that lets bacteria resist polymyxins—the last line of antibiotic defense we have left—has shown up in widespread bacteria samples from pigs and patients in south China, including strains with epidemic potential. Read More
An experimental vaccine to protect against the mosquito-borne illness chikungunya is being tested in a Phase 2 trial sponsored by the National Institutes of Health. Results from an initial trial of the vaccine, which was developed by scientists at the NIH National Institute of Allergy and Infect... Read More

This artwork is made from Escherechia coli in Mac Conkey Agar ( MCA ) and shows the other side of the biggest Buddhist temple in Indonesia and Southeast Asia built by the Syailendra dynasty called “Borobudur”, that included one of the wonders of the world from Indonesia.
Scientists have identified a gene that could potentially open the door for the development of new treatments of the lethal disease sepsis. Read More
Almost every second woman suffers from a bladder infection at some point in her life. Also men are affected by cystitis, though less frequently. In eighty percent of the cases, it is caused by the intestinal bacterium E. coli. It travels along the urethra to the bladder where it triggers painful... Read More
