CRISPR-Cas9 enables efficient genome engineering of the strictly lytic, broad-host-range staphylococcal bacteriophage K

mycolabadmin

Scientists have developed a new method to genetically engineer bacteriophages—viruses that infect bacteria—to fight antibiotic-resistant Staphylococcus aureus infections. Using CRISPR technology, they created a special phage that glows when it infects S. aureus cells, allowing doctors to quickly detect this dangerous pathogen in patient blood samples and other clinical samples. This engineered phage works against most S. aureus strains tested, regardless of their resistance to vancomycin, and could lead to new diagnostic tools and treatments for drug-resistant bacterial infections.

Development of reverse transcription loop-mediated isothermal amplification-based assay for rapid and specific detection of human fungal pathogen, Candida auris

mycolabadmin

Researchers developed a new rapid test called RT-LAMP to detect Candida auris, a dangerous multidrug-resistant fungus that causes hospital infections. The test works by changing color from pink to yellow when the fungus is present, making it easy to read without special equipment. It is more sensitive and specific than current methods, can be done quickly at a single temperature, and costs much less than existing tests, making it ideal for hospitals and clinics with limited resources.

Analytical Validation of a Next-Generation Sequencing Assay for the Detection of Microbial Pathogens in Human Plasma

mycolabadmin

Researchers developed a new blood test that can detect hundreds of different fungal and bacterial infections using advanced sequencing technology. The test works by searching for pathogen DNA in blood samples and is much faster than traditional culture methods. This could help doctors quickly identify what infection a patient has and start the right treatment sooner, which is especially important for patients with weakened immune systems.
