How does Mycobacterium tuberculosis infect the lung?

Tuberculosis (TB) is the most common major infectious disease today. It is estimated that two billion people--or one-third of the world's population--are chronically infected without active symptoms. Nine million new cases of active disease are diagnosed annually, resulting in two million deaths. TB is ...

In results presented today at a large infectious disease meeting, the annual Interscience Conference on Antimicrobial Agents and Chemotherapy in Washington, doctors who reviewed the treatment given to 11,426 children showed that even a short course of the newer drugs is more effective than the trad...

Greasing interferon's gears may pave way to greater therapeutic benefits, fewer side effects

...iates the body's defense against a wide variety of infectious agents and tumors -- may soon have greater therapeutic value as the result of a new study by researchers at Washington University School of Medicine in St. Louis. "Essentially, we found a way to grease the gears that drive the interferon signal," s...

Rapid diagnosis of infectious diseases?/B> Scientists at the Universities of Bath and Glasgow, with colleagues from Stobhill Hospital and Atlas Genetics Ltd are miniaturising established molecular techniques and combining them with novel assays to develop a hand-held 'chip' t...

The bioweapon is in the post

...e State University of New York at Stony Brook made infectious polioviruses from synthetic DNA. And just last month, researcherswith the US Centers for Disease Control and Prevention in Atlanta, Georgia, said that they had used similar means to recreate the virus that caused the 1918 flu (New Scientist, 8 Octobe...

Bacteria that cause tooth decay able to survive without important biochemical pathway

...d has the potential to become a target in fighting infectious diseases, he said. "Really, we started with a very basic question related primarily to S. mutans, 'how does this bacteria tolerate acid?'" said Brady. "Asking that question has opened the door much more widely to learning things that are more fundam...

UCLA scientists discover immune response to HIV differs, even in identical twins

...rward," said Dr. Otto Yang, associate professor of infectious diseases at the David Geffen School of Medicine at UCLA, and the study's lead researcher. According to the UCLA researchers, the results of this study have broader implications, and could apply to other viruses such as cytomegalovirus (CMV), a herpe...

Picking particles faster than one at a time

...biological activity -- for example, the ability of infectious bacteria to synthesize proteins can be wrecked by jamming their ribosomes, if the ribosome structure is known in detail. Single-particle reconstruction with cryo-EM holds the promise of providing many high-resolution structures which may be difficult...

Infant transplant patients resist infections that kill adult AIDS patients

...f AIDS patients -- perhaps even more vulnerable to infectious diseases. Yet 10 years post transplant, the patients don't suffer from infections as AIDS patients do. So promising is the work that it recently garnered a $6 million grant from the National Institutes of Health to support further research into the ...

Web model of influenza-host lifecycles will aid scientists in creating anti-viral drugs

...ime Reactome has displayed interactions between an infectious pathogen and its host, Dr. Scheuermann said. Pathogens such as influenza have evolved to use hosts to promote their growth, while at the same time blocking the host reactions that recognize and respond to infection. Each year, for example, winter is...

"Providing free HIV tests increases the number of clients presenting for evaluation and makes HIV prevention more cost-effective. We changed our practice because of these results," Thielman sai...

Infection 'alarm' yields clues to immune system behavior

...tein delivers its warning message to cells when an infectious agent invades the body. The findings are important because this biological intruder alarm causes the body's immune system to leap into action to fight the infection. Learning more about how this process works, the researchers said, could lead to bett...

This is another step on the way to point-of-care diagnostics." The technology potentially could detect any ...

Researchers map of genetic variations implicated in disease

...voured immunological advantage (e.g. resistance to infectious disease), can spread across haplotypes and populations. Professor John Trowsdale, at the Department of Pathology, University of Cambridge, said, "The region, called DR-DQ, where we find this island of stability is one of the most variable in our gen...
