To do this, Julie Laurent irradiated the bacterial cells with UV-C light, which damages random ... of the DNA damage and to thereby induce mutations. Using a miniature apparatus, she then ...

The mutation was observed across multiple independent bacterial populations, occurring predictably in 137 out of 153 replicate cultures. This mutation is directly linked to transcriptional ...

In bacteria, mutations in plasmids can accumulate surprisingly fast. What does this mean for us humans, who have to fight with these new antibiotic resistant strains? Now, say that a few days ...

coli to ultraviolet (UV) light and ... to identify the first mutation that conferred radiation resistance in E. coli. This discovery was crucial in establishing that bacteria have active ...

When they introduced an F158C mutation in the PheS of pathogenic Klebsiella pneumoniae and enterohemorrhagic E. coli, bacterial strains that commonly cause disease in people, the mutants exhibited ...

Bacteria and several other organisms also possess another mechanism to repair UV damage called photoreactivation ... however (Sinha & Hader, 2002). Mutations in an organism's DNA are a part ...

Killing bacteria and viruses with UV light is particularly effective because it kills germs regardless of drug resistance and without toxic chemicals. It is also effective against all germs ...

In this study, we showed that 310 nm UV-LED irradiation had weak bactericidal effects on oral bacteria but showed low toxicity to gingival epithelial cells. It also induced the production of ROS ...

A genomic study of skin cells shows that there’s a wide range in the normal number of somatic mutations that arise from exposure to UV light and that these mutations are independent of age. The work, ...

Recent research has unveiled a novel mechanism linking CRB1 mutations to retinal degeneration through bacterial translocation from the gut to the eye, opening up promising therapeutic avenues.
