Scientists discovered bacterial secretion system prompting sharing of genetic material between bacteria

According to a recent research conducted by the researchers at Birkbeck, University of London and UCL uncovered the system that helps the sharing of genetic material among the bacteria and hence helps in antibiotic resistance The study was published in scientific journal Nature. The study explains about the mechanism of bacterial type IV secretion. It is through this bacteria that is been used to move the substances through cell wall. Further it also plays an important role in secreting out toxins, infections. Carrying these toxins may lead to ulcers, whooping cough, pneumonia and Legionnaires' disease. The lead Professor Waksman from the Institute of Structural and Molecular Biology explains, “This work is a veritable tour de force. The entire complex is absolutely huge and its structure is unprecedented. It is the type of work which is ground-breaking and will provide an entirely new direction to the field. Next, we need to understand how bacteria use this structure to get a movie of how antibiotics resistance genes are moved around.”
