The human navel contains hundreds of microorganisms. Indeed, a recent study has just exposed that the navel is a nest of bacteria that has more than 60 different species of fungi and bacteria. Although this study found an average of 60-70 dissimilar species, over 1400 species have been discovered in different navels, highlighting a huge disparity between people.
What says study?
Bacteria located at the level of the navel skin of 391 individuals, men and women of all ages and from all ethnic backgrounds that had different life hygiene’s were surveyed. The researchers focused on the nature of the bacteria found in the samples, but also in the presence of very interesting fungi. Scientists have long established the viability of these organisms in culture and have sequenced the DNA of each species found. Early results point to that the number of organisms found in each individual varies greatly.
So far, no hypothesis has been able to clearly explain the variability of bacterial community in terms of individuals. The detached differences of this study are unrelated to the sex of the individual, their origins and age, even with their daily hygiene. Therefore, the answer lies elsewhere.
However, researchers have been able to conclude that we all share a small group of bacterial species, along with hundreds of other rare species whose presence depends on each individual. These bacteria are a defense shield. Indeed, we share different bacteria, but the presence of other class depends on the individual history and, therefore, it is impossible to predict.
Researchers have chosen as a subject of study this area of the body, since the navel is a nest of bacteria that soaps, creams and ultraviolet have difficulty to remove. If you think disinfect the navel, remember that these organisms, also present in the forearms, hands and skin surface plays an necessary role for health. Indeed, it is a first line of defense against pathogens that are placed upon us, a small army of skin has to react and fight new pathogens found. A human being detached from all bacteria present in the body is at risk of developing a life-threatening infection of the skin.
