The study findings, which were published in the Journal of Clinical Investigation, have revealed that the human body can create a natural plaster that helps keep out "bacteria and other micro-organisms from penetrating open wounds."
In the study, the researchers discovered that a protein film, which quickly forms over a wound as part of the natural clotting process, protects a wound for about 12 hours. They posited that oil-based substances may interrupt this process.
In fact, using petroleum jelly on breaks in the skin may do more harm than good. Participants in contact sports, who often use the product on wounds after minor surgery, may even be increasing their risk of developing an infection.
Clotting is a crucial process that helps prevent fatal blood loss after an injury. When blood clots in at the site of the wound, platelets and red blood cells form together to plug any hemorrhage.
With powerful imaging techniques, the researchers observed fibrin fibers acting as nature's shape-shifters as they reorganized their structure "from a fibrous network into a sheet-like film at the point the clot comes into contact with air, at the site of the open wound." They reported that under an electron microscope, clots were seen meshed together via the spaghetti-like fibers of fibrin, a protein.
Before the study, scientists were perplexed about the specific components of the fibrin fibers since they seemed to be unending. The fibers coiled were also seen coiled around the platelets and red blood cells.
The data from the study showed that the fibrin fibers turned into a protective film with "breathability" properties, letting air reach the wound via minuscule pores that were too small for bacteria and some viruses to pass through.

Professor Robert Ariëns, who led the research, explained that their hypothesis concerned the film acting as a plaster and a protective barrier that tried to prevent microbes from entering the body via the broken skin. Ariëns, who is from the Leeds Institute of Cardiovascular and Metabolic Medicine, added that based on data from studies on animal and human tissues, the bio-film could act as a barrier against microbial infection for at least 12 hours. This gives the immune system enough time to send white blood cells to the wound to prevent infections. Clots then prevent blood loss and act as a front-line defense against infection.
The study authors noted that their discovery can revolutionize the current understanding of the mechanism of blood clotting. The findings showed that scientists working with electron microscopes previously saw a thin film on top of clots, which they thought formed because of how the sample was prepared for examination.
Professor Jeremy Pearson, Associate Medical Director at the BHF, shared that by studying how blood clots form, the research team has uncovered a previously unknown protection mechanism used by the human body to fight infection following an injury. Pearson concluded, "This discovery perfectly portrays the complex, and sometimes contradictory nature of our bodies, in that the very substance which can make blood clots inside our body so dangerous can also protect us from harm when we wound ourselves."
