A study released today from the upcoming issue of the Journal of the Pediatric Infectious Diseases Society (JPIDS) found that taking early and repeated white blood cell counts (WBC) is critical in determining whether infants have pertussis and which of those children are at highest risk of death...

The production of Metallo-β-lactamase is one of the resistance mechanisms of Pseudomonas aeruginosa. Metallo-β- lactamases are members of Group B in the molecular classification of Ambler and are Clavulanic acid resistant enzymes which require divalent cations of zinc as co-factors for enzymat...

Thousands of deaths from tuberculosis (or TB), an infectious bacterial disease, could be prevented using a new hand-held device that is being developed to detect potentially fatal drug resistance in less than 15 minutes.
Currently neither the TB infection itself, nor those people with strains... Read More
The flu knows how much time it has to multiply, infect other cells, and spread to another human being before the immune system kills it.
Scientists have discovered that that the flu virus can essentially tell time, thereby giving scientists the ability to reset the virus' clock and combat it ... Read More
A compound from the South African toothbrush tree inactivates a drug target for tuberculosis in a previously unseen way.
Tuberculosis causes more deaths worldwide than any other bacterial disease. At the same time as rates are increasing, resistance strains are emerging due, in part, to non-com... Read More
Death is what fungi are all about. By feasting on the deceased remains of almost all organisms on the planet, converting the organic matter back into soil from which new life will spring, they perform perhaps the most vital function in the global food web. Fungi, which thrive on death, make all ... Read More
Conventional wisdom holds that genes determine the shape and structure (morphology) of animals, but something else may be at play. A new study shows that a roundworm (P. pacificus) regulates its offspring's morphology by using a potent cocktail of small-molecule signals. Exposure to trace quanti... Read More
The people on the front lines of tuberculosis control have their hands full, but their biggest challenge for the moment may be containing strains of the disease that are resistant to drugs.
Worldwide the number of TB cases is going down. The bad news is that the number of drug-resistant cases... Read More
Bacteria that resist antibiotics are a growing problem worldwide, but one we thought we could limit or even reverse by better control of the drugs. The situation may be more complicated: some bacteria that have never seen an antibiotic can evolve resistance, and even thrive on it.

Our bodies are made up by cells containing our own DNA. Plus 10 times as many with foreign DNA. The bacteria found on our skin, and inside our organs (intestine, vagina, mouth, nose, etc.) are referred to as our “microbiome”, outnumber our own cells by 10 to 1, and make up a vital organ with ind...

Yesterday many US newspapers carried front-page stories on the severity of influenza so far this season. The New York Times story began with “It is not your imagination — more people you know are sick this winter, even people who have had flu shots.” Is this really a bad flu season? Read More
Florida health officials are encouraging the state’s residents not to be alarmed following another death from the flesh-eating bacteria Vibrio vulnificus. The rare bacteria that thrives in saltwater has killed 10 people in Florida this year, while 31 people in all have been infected with the ... Read More
Bacteria from a healthy person can be transplanted to an ill person to help them recuperate. Visiting Jamaican-born Prof Karen E Nelson, president J Craig Venter Institute, explained this was one of the strides being made in genomics, which is the study of the collective genetic material in an o...

Scientists at the U.S. National Institutes of Health are attempting to find out more about a lethal new coronavirus and determine if it will become a pandemic or stay a limited threat.
Vincent Munster, a representative of the NIH’s Virus Ecology Unit, attended the annual meeting of the Biodef... Read More
El podcast del microbio Nº 366 summarize a recent article published in PNAS on the characterization of the critical step in HIV-1 protease maturation by using bioinformatics tools. El podcast del microb... Read More
New research led by the Karolinska Institutet, Sweden and the University of Glasgow, Scotland, has identified a link between a human gene and the composition of human gastrointestinal bacteria. In a study published as a letter to the journal Gut, the team outline new evidence suggesting that th... Read More
The World Health Organization’s campaign to eradicate poliomyelitis made impressive inroads in 2012: only 212 cases were reported, compared with 620 the previous year; moreover, India remained polio-free. The dark side of this story is that as wild polio is eliminated, vaccine-associated poliomy... Read More
Infants' early growth is influenced by the types of bacteria in their digestive system, a new study says.
A variety of bacteria quickly populate the sterile digestive tract of a newborn. Norwegian researchers identified connections between specific types of bacteria and infant growth rates.

When you purchase chicken eggs at the market, they usually have white or brown shells. But some breeds of chicken produce blue or green eggs. The blue color is caused by insertion of a retrovirus into the chicken genome, which activates a gene involved in the production of blue eggs. Read More
From the shiny, strong nacre that gives abalone shells an unbreakable, opaline sheen, to the goopy mix of proteins fired by a velvet worm that solidify and trap prey upon impact, nature is packed with inspiration for scientists designing new materials.
Waterproof adhesives and self-cleaning s... Read More
