Cell Discovery Could Lead to Strep Throat Vaccine

A new study clarifies how Group A Streptococcus (strep) bacteria resist the human immune system.

The research could eventually lead to the development of a safe vaccine against strep throat, necrotising fasciitis (flesh-eating disease), and rheumatic heart disease.

Previous efforts to deve... Read More

Chikun-What? A New Mosquito-Borne Virus Lands In The U.S.

Pediatrician Jennifer Halverson will never forget her 36th birthday.

The St. Paul native was volunteering at a maternity clinic in Port-au-Prince, Haiti. She felt great — she went to her job that day and then out to dinner with friends.

But when she got home and went to sleep that night in... Read More

A Possible Solution to Toilet Stink in China

Using public toilets in China can often be a challenging undertaking, particularly for those not practiced in the art of squatting. But researchers in China have come up with a new technology that they say can help eliminate one of the most noxious of problems to plague China’s public lavatories... Read More

Host genetics can contribute to lung damage in severe tuberculosis

A third of the global population is infected with the bacterial pathogen that causes tuberculosis. Most carriers control the infection and are asymptomatic, but severe forms of the disease kill over a million people every year. A new article now identifies a factor made by the host that exacerba... Read More

Will Wolbachia help defeat dengue?

One of the Wellcome Trust’s areas of focus for research funding is combatting infectious disease. We have recently agreed a strategic award of over £7.5 million to continue development of an effective and sustainable approach to reducing the transmission of dengue fever. The research is an inte... Read More

Plant Pathogen Silences Host’s Immune Genes

As more and more information becomes available, one marvels (and also frets) at the sophisticated strategies that pathogens have evolved in order to evade their hosts’ defense mechanisms. Many pathogens of plants and animals deliver effectors into their hosts in order to suppress immune response... Read More

Have a Happy Bioluminescent Fourth of July!

In this post from my Microbiology/Education blog, I wish everyone a lovely day of food, fellowship, and fireworks. My laboratory brings you our own "fireworks" through bioluminescence! Read More

MoMA PS1's Mushroom Tower | Hy-Fi by The Living

For MoMA PS1's Young Architect Program, David Benjamin and the architecture firm, The Living, utilized cutting-edge bio-design technologies to create a completely organic, compostable tower. The winning structure is composed of discarded cornstalks and mushroom material, and used zero energy in ... Read More

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
