 ==== Cyanobacteria ====
-Cyanobacteria are a group of self-living organisms, formerly considered plants and nowadays considered to be bacteria. They can be found in almost every environment on Earth and are resistant to prolonged drought, high temperatures, and even high salinity or acidity of the substrate. During so-called blooms, some strains of cyanobacteria, secreting poisonous substances. [([[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4838734/|National Center for Biotechnology Information]])]

 ==== Shigella ====
-Shigella - a type of Gram-negative bacteria. These bacteria cause dysentery. The only reservoirs of the bacteria are humans and monkeys. The bacteria were first isolated and described in 1897 by the Japanese microbiologist Kiyoshi Shiga. [([[https://www.cdc.gov/shigella/index.html|CDC]])]

 ==== Bungle Bungle ====
-Purnululu Park in Australia is known for its karst formations formed by the weathering of sandstone The individual mountains with beehive-shaped domes are up to 820 ft high. The orange layer corresponds to iron oxides, while the black color is responsible for the fossils of cyanobacteria (bacteria) belonging to at least 5 different species. Cyanobacteria fossils in the form of layers in the Bungle Bungle mountains are evidence of one of the earliest colonization of arid areas by organisms.

+==== Belly button ====
+The place on the human body where we can find the greatest number of bacteria is the belly button. There are ideal conditions for their development - moisture and warmth.

+==== Hand dryers ====
+Using hand dryers in public restrooms increases the number of bacteria on our hands. [([[https://www.healthline.com/health-news/study-finds-air-hand-dryers-can-spread-more-germs-than-paper-towels|Health Line]])]
+==== Species of bacteria ====
+We have no way to study all the species of bacteria living on earth because the number is too large. [([[https://theconversation.com/how-many-species-on-earth-why-thats-a-simple-question-but-hard-to-answer-114909|The Conversation]])]
+==== Bacteria in human body ====
+The amount of bacteria in the human body is enormous. They outnumber our own cells and weigh almost as much as our brains. [([[https://www.bbc.com/news/health-43674270|BBC]])]
+==== Bacteria lifespan ====
+Species of bacteria vary in their lifespan. Some live a few weeks, while others can live up to 4 years. [([[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1564025/|National Institute of Health]])]
+==== Shaking hands ====
+There are 3200 bacteria on human hands. When we shake hands to greet each other, we exchange them with other people. [([[https://elemental.medium.com/can-we-all-please-just-stop-shaking-hands-ffd8cac7574e|Medium]])]
+==== Cutting board ====

+==== Gut fingerprint ====
+The microbiome is like a fingerprint. Although we all have a similar set of genes derived from bacteria that enable us to function in the natural world, no two people in the world have the same microbial makeup. [([[https://www.gutmicrobiotaforhealth.com/your-microbiome-is-like-a-unique-fingerprint/|Gut Microbiota For Health]])]
+==== Four pounds of bacteria ====
+There are over 4 pounds of bacteria in our gut. By coming into contact with them, the body learns acquired immunity because the gut is where 80% of the immune system cells (GALT) are located.

+==== Inflammation ====
+Even probiotic bacteria that end up not where they are supposed to be can become the root of a serious illness, such as sepsis or peritonitis. [([[https://www.webmd.com/digestive-disorders/peritonitis-symptoms-causes-treatments|WebMD]])]
+==== Umbilical cord and placenta ====
+The baby's contact with the umbilical cord and placenta after birth supports proper colonization of the baby's digestive system. [([[https://www.frontiersin.org/articles/10.3389/fcimb.2020.573735/full|Frontier Sin]])]
+==== Child's temperament affected by bacteria ====
