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 […]

Hospital staff errors with gowns and gloves spread antibiotic-resistant bacteria

During the study, the workers oversaw 95 patients with contact precautions for methicillin-resistant Staphylococcus aureus, or MRSA, as well as vancomycin-resistant Enterococci and multidrug-resistant gram-negative bacilli. (iStock) Health care workers caring for infectious patients sometimes make mistakes when removing personal protective garments, resulting in contamination of clothes or equipment with antibiotic-resistant bacteria, a small study […]
