Immune system targets vitamin B12 pathway to neutralize bacteria

Close to 1.8 billion people worldwide are infected with Mycobacterium tuberculosis (Mtb), the common and occasionally deadly bacterium that causes millions of cases of tuberculosis each year. The bacteria, having coevolved with humans over millennia, have devised ways of hijacking nutrients from its human host for its own benefit. Humans have equally complex ways of […]

Combating mosquito-borne diseases with bacteria

Viruses, spread through mosquito bites, cause human illnesses such as dengue fever, Zika and yellow fever. A new control technique harnesses a naturally occurring bacterium called Wolbachia that blocks replication of viruses and breaks the cycle of mosquito-borne disease, according to an international team of researchers. “Wolbachia is present in around 50 percent of all […]

Could better tests help reverse the rise of drug-resistant infections? Modeling study says yes in theory; now comes a reality check

A growing number of infections — such as pneumonia, gonorrhea and tuberculosis — are becoming harder to treat, as bacteria evolve defenses against antibiotics faster than we can develop new drugs to replace them. Duke University game theorist David McAdams says faster, more accurate tests for drug-resistant infections are being developed that could, at least […]

On-chip drug screening for identifying antibiotic interactions in eight hours

A KAIST research team developed a microfluidic-based drug screening chip that identifies synergistic interactions between two antibiotics in eight hours. This chip can be a cell-based drug screening platform for exploring critical pharmacological patterns of antibiotic interactions, along with potential applications in screening other cell-type agents and guidance for clinical therapies. Antibiotic susceptibility testing, which […]
