Foodborne bacteria can cause disease in some breeds of chickens after all

Contrary to popular belief, the foodborne pathogen Campylobacter jejuni is not a harmless commensal in chickens but can cause disease in some breeds of poultry according to research. Campylobacter jejuni is the most frequent cause of foodborne bacterial gastroenteritis in the world and the Cente... Read More

Human Protein Cleans Bacteria from Drinking Water

Researchers in Japan have shown that they can remove Escherichia coli from drinking water using tiny tubes made of human serum albumin.

E. coli is a very common type of bacteria, many strains of which are harmless. Some strains, however, such as enterohemorrhagic E. coli O157, are life-threat... Read More

Implications of finding poliovirus in sewers of Brazil and Israel

Wild poliovirus has been detected in the sewers of Brazil and Israel. Fortunately, no cases of poliomyelitis have been reported in either country. Why is poliovirus present in these countries and what are the implications for the eradication effort?

Wild type poliovirus (e.g. not vaccine-deri... Read More

MALARIA MAKES ITS HOST SMELL BETTER TO MOSQUITOES

Malaria parasites can change their host’s scent to attract mosquitos and spread their offspring, report researchers, who say the scent change could be used as a diagnostic tool.

“Malaria-infected mice are more attractive to mosquitos than uninfected mice,” says Mark Mescher, associate profess... Read More

New analysis of 'swine flu' pandemic conflicts with accepted views on how diseases spread

The most detailed analysis to date of the spread of the H1N1 2009 pandemic influenza virus, known informally as ‘swine flu’, has found that short-range travel was likely the primary driver for the 2009 pandemic in the United States, in contrast with popularly accepted views on the way diseases s...

Scientists Show That Bacteria Can Evolve a Biological Timer to Survive Antibiotic Treatments

The ability of microorganisms to overcome antibiotic treatments is one of the top concerns of modern medicine. The effectiveness of many antibiotics has been reduced by bacteria's ability to rapidly evolve and develop strategies to resist antibiotics. Bacteria achieve this by specific mechanisms... Read More

Guo Lab Reports Finding of Revolution Biomotors in Many Bacteria and Viruses

Scientists at the University of Kentucky, led by nano-biotechnologist Peixuan Guo, have made some critical discoveries over the past year into the operation of biomotors, the molecular machines used by viruses and bacteria in the packaging of DNA.

Biomotors function similarly to mechanical mo... Read More

Research may yield new ways to treat antibiotic-resistant TB

Scientists in the United States and India have successfully modified the precursor to one of the drugs used to treat tuberculosis, an important first step toward new drugs that can transcend antibiotic resistance issues that experts consider a serious threat to global health.

The findings, re... Read More

Fighting parasitic infection inadvertently unleashes dormant virus

Signals from the immune system that help repel a common parasite inadvertently can cause a dormant viral infection to become active again, a new study shows.

Further research is necessary to understand the clinical significance of the finding, but researchers at Washington University School o... Read More

How deadly lassa virus infects cells

The Lassa virus, endemic to West Africa, uses an unexpected two-step process to enter cells, research has shown. The results suggest that the mechanism by which Lassa virus causes infection is more complicated than previously known, and could lead to new approaches for preventing the disease.

Microbe, Enzyme or Mineral? A Riddle in the Soil

When most people look at soil, they just see dirt. When I look at soil, I see billions of microorganisms crawling atop one another, consuming the dead in a feasting frenzy that stops for nothing save a deep freeze. I see microbes and their enzymes, the digestive juices that break down, transform... Read More
