A study published in the journal Proceedings of the National Academy of Sciences scientists have developed a new way to fight harmful bacteria.
Scientists at Lund University claim to have cracked the mystery of how our body quickly prevents an infection from spreading uncontrollably during wound healing, an advance that may lead to new ways to counteract harmful bacteria.
The aggregation takes place quickly in the wound and causes bacteria and toxins not only to gather but also to be “eaten” by the body’s inflammatory cells.
Through this mechanism, the body itself is able to halt spread of the infection and this method could help us fend off both bacteria and their toxins during wound healing.
The team found that fragments of thrombin – a common blood protein found in wounds – can aggregate both bacteria and their toxins; something that was not see in normal blood plasma.
Better approach to battle hurtful microorganisms found
as informed in “I have always been fascinated by how nature has effectively created different defence mechanisms, and wound healing provides a rich source of new discoveries,” said Artur Schmidtchen, also a Professor at Lund University.
We believe this to be a fundamental mechanism for taking care of both bacteria and their toxins during wound healing,” said Petrlova, lead author of the study published in the journal Proceedings of the National Academy of Sciences (PNAS).
“This way, the body avoids the spread of the infection.
“The ability to effectively heal wounds is of evolutionary significance to our survival,” said Schmidtchen.
“Perhaps we do not need to kill them with antibiotics but simply gather them so that the body can better take care of the infection,” said Jitka Petrlova, Professor at Lund University in Sweden.
as informed in A new UCLA-led study shows that beneficial bacteria from mothers do much the same thing.
The study found that 30 percent of the beneficial bacteria in a baby’s intestinal tract come directly from mother’s milk, and an additional 10 percent comes from skin on the mother’s breast.
The origin of breast milk bacteria remains unclear; one hypothesis is that it travels to the breast from the mother’s intestine.
After birth, beneficial bacteria from the mother and environment colonize the infant’s intestine, helping digest food and training the baby’s immune system to recognize bacterial allies and enemies.
They would like to test in the lab how bacteria that are provided through breast-feeding are critical in infants’ immune responses, and determine which beneficial bacteria are missing in people who have certain diseases.
