Analysis reveals malaria, other diseases as ancient, adaptive and persistent foes

One of the most comprehensive analyses yet done of the ancient history of insect-borne disease concludes for the first time that malaria is not only native to the New World, but it has been present long before humans existed and has evolved through birds and monkeys.

The findings, presented i... Read More

Half of hospital rooms rife with drug-resistant bug, study finds

Nearly half of hospital rooms of patients infected with drug-resistant strains of Acinetobacter baumannii are contaminated with the bacteria, a small new survey shows. Surfaces such as bedrails, drawer handles and touchpads are particularly prone to harboring the germ.

That could pose big pro... Read More

Global Microbe Study Finds ‘Black Market’ of Superbug Genes

Researchers have discovered an underworld of genetic exchange among bacteria, one more vast than previously imagined.

A comparison of thousands of bacterial genomes from around the world found genes flowing easily between species separated by hundreds, even thousands of miles. Whether the ba... Read More

Bacterium's role in gastric cancer studied

U.S. researchers say they've discovered how a cancer-causing bacterium attacks a cell's energy infrastructure, ultimately causing the cell to self-destruct.

Helicobacter pylori are the only bacteria known to survive in the human stomach and infection with the bacterium is associated with an i... Read More

Treponema pallidum

Dark-field preparation of Treponema pallidum. (approx X1000). Taken from the Wistreich Collection, appearing exclusively on MicrobeWorld. Read More

Team discovers how a cancer-causing bacterium spurs cell death

Researchers report they have figured out how the cancer-causing bacterium Helicobacter pylori attacks a cell's energy infrastructure, sparking a series of events in the cell that ultimately lead it to self-destruct.

H. pylori are the only bacteria known to survive in the human stomach. Infect... Read More

Amerithrax review: Lessons for future investigations

When the National Academy of Sciences issued its review of the FBI anthrax investigation earlier this year, the press fixated primarily on one point: The report found no conclusive evidence that Bruce Ivins, the Army scientist the government contends was responsible for a series of anthrax-laced...

Multidrug-Resistant Acinetobacter Baumannii Found Growing in Nearly Half of Infected Patient Rooms

Multidrug-resistant Acinetobacter baumannii (MDR-AB) was found in the environment of 48 percent of the rooms of patients colonized or infected with the pathogen, according to a new study published in the November issue of the American Journal of Infection Control, the official publication of API...

Ten seminal virologists

In my recent keynote address to the Brazilian Virology Society entitled The World of Viruses, I presented my list of ten seminal virologists. The idea to include such a discussion came from David Baltimore, who sent me his list. Our lists had some but not all individuals in common. What would yo... Read More

'Protein Microarrays' May Reveal New Weapons Against Malaria

A new research technology is revealing how humans develop immunity to malaria, and could assist programs aimed at eradicating this parasitic disease.

Dr Alyssa Barry from the Walter and Eliza Hall Institute's Infection and Immunity division is using 'protein microarray' technology to screen h... Read More

In Some Cases, Even Bad Bacteria May Be Good

Overuse of antibiotics has led to the creation of drug-resistant bacteria — so-called superbugs, like methicillin-resistant staphylococcus aureus. But now some researchers are exploring an equally unsettling possibility: Antibiotic abuse may also be contributing to the increasing incidence of ob... Read More

Fecal microbiota transplants effective treatment for C. difficile, Inflammatory Bowel Disease

Growing evidence for the effectiveness of fecal microbiota transplants as a treatment for patients with recurrent bouts of Clostridium difficile (C.difficile) associated diarrhea is presented in three studies -- including a long-term follow-up of colonoscopic fecal microbiota transplant (FMT) fo...

Mould Fungi Can Cure Plants

We know them from our garden, from damp cellars or from the fridge -- mould fungi can be found almost everywhere. Their success is due to their remarkable versatility: depending on external conditions, they can choose quite different lifestyles. Sometimes fungi can be very useful for plants. The... Read More

Hey, bacteria, get off of my boat!

Submerge it and they will come. Opportunistic seaweed, barnacles, and bacterial films can quickly befoul almost any underwater surface, but researchers are now using advances in nanotechnology and materials science to design environmentally friendly underwater coatings that repel these biologica...

IDSA: Cancer Gene Plays Key Role in HIV Infection

A gene formerly known as a tumor suppressor may play a role in a so-called "functional cure" for HIV, a researcher said here.

The gene, dubbed p21, is highly overexpressed in the CD4-positive T cells of "elite controllers" -- people infected with HIV who do not lose immune cells or have the v... Read More
