Researchers have found a compound that can act like a bed of nails, fending off microbes from colonizing wound dressings and other implantable devices. Coating these devices with the compound could help prevent thousands of bacterial and yeast infections annually.
The National Institute of General Medical Sciences (NIGMS) will award $13 million to create four centers to develop new treatments for various types of wounds, including burns, diabetic ulcers, and bedsores. This initiative aims to deepen understanding of wound healing and apply knowledge to enhance treatment.
A groundbreaking study found that nearly all children with chronic otitis media have resistant biofilm bacteria in their middle ears, rendering antibiotics ineffective. This discovery sheds new light on the treatment of chronic ear infections and suggests alternative approaches such as probiotics.
Researchers at UT Southwestern found that MRI offers more detailed views and specific information on cochlear implants than CT scans. This enables surgeons to determine the best surgical technique, electrode arrays, and ear placement for each patient.
Researchers discovered that GroEL1 oversees production of fatty acids necessary for biofilm growth, which are absent in bacteria lacking the chaperone protein. Understanding this mechanism could lead to new ways to develop effective drugs to fight TB and other mycobacterial infections.
Researchers found that Pseudomonas aeruginosa biofilms develop faster in the presence of neutrophils, which are sent to fight infections. The biofilms become resistant to antibiotics and the immune system, leading to chronic lung damage and death.
Tap water is a significant source of hospital-acquired infections, with biofilm harbouring pathogenic microorganisms. Point-of-use 0.2 micron filters can significantly reduce the release of pathogens and aerosols, providing an absolute barrier between patients and contaminated water.
Researchers aim to control biofilm formation by manipulating quorum sensing in bacteria. They are designing new compounds that mimic natural molecules to disrupt bacterial signaling, potentially preventing hospital infections.
A recent study published in Journal of Bacteriology has identified the HipA gene responsible for making persister cells resistant to antibiotics. Biofilm infections, which can cause fatal lung infections, periodontal disease, and other serious health issues, are notoriously difficult to treat.
Researchers at the University of Iowa found that bacteria in biofilms rapidly diversify, providing a form of biological insurance against adverse conditions. This diversity increases the bacteria's capabilities and may contribute to the difficulty in eradicating chronic infections caused by biofilms.
The RetS gene product in P. aeruginosa activates virulence factors for acute infection while repressing those required for long-term, chronic infection. This system may orchestrate the transition from acute colonization to chronic infection in this human pathogen.
