Many bacteria form spores that can survive in the air, causing the microbe to spread within a household, even if its members are not close to each other

You probably share more with the people you live with than you realize — including as much as a third of your bacteria in your mouth.
Physicians are increasingly interested in the health effects of hundreds of species of bacteria, Virus, fungus and parasite live in our intuitionoral cavity and other parts of our body inside and outside, known as microbiome.
Nicola Segata At the University of Trento in Italy, he and his colleagues analyzed the results of 31 previous studies involving the microbes of people living together or in close proximity to each other in 20 countries, including parts of Europe, North and South America, Africa and Asia. Group.
The studies included nearly 10,000 stool or saliva samples and recorded whether family members were partners, relatives or friends. The bacterial strains present were identified genetically.
The team found that family members were more likely to share oral bacterial strains than gut bacteria.
Across all studies, family members shared 32 percent of oral bacterial strains compared with 12 percent of gut bacterial strains. Only 3 percent of the oral bacteria were the same among non-cohabiting members of the same population.
This shows how common it is for people to spread germs to other people, even those they haven’t kissed or haven’t gender And, Segata said.
Oral bacteria can be easily shared because many bacteria form spores that can survive in the air for a long time, he said.
