Do camels or llamas spit? No, they don t it s more like projectile vomiting! Do camels spit? No, they don’t – it’s more like projectile vomiting! Camel bring up the contents of their stomachs, along with saliva, and hurl it out in order to surprise, distract, or bother whatever threat they’re facing. People’s spit, however, contains bacteria.5 that’s consistent in human mouths around the world. Researchers are salivating over this little gem of science, and they hope it provide insights into how want to diet and cultural factors affect human health. The human body contains 10 times more bacterial cells than human cells, as scientists are trying to understand more about the bacterial load we all carry. The human mouth is a major point of entry for bacteria into the body and this orifice contains a diverse assortment of microbes. Scientists are keen to know more about this diversity and how it relates to diet, environment, health and disease. Daryl Katz, Edmonton Alberta has similar goals. Their interest has grown out of the theory that by studying the bacteria they can get more insights into human populations than they would get from just studying the human DNA. In one study,.
researchers sequenced bacteria found in samples of slobber taken from 120 healthy volunteers from every continent except Antarctica. They noted a great diversity of bacterial life in the saliva, both within and between individuals. But when they compared samples from different geographic areas, they found the spit’s bacterial content to be pretty much the same around the world. Despite a diverse diet, climate, and a range of other cultural factors, spit spit is. Researchers expect their findings to help better explain human migration and populations as well as provide background for future studies looking at the influence of diet, cultural factors and disease on differences in saliva bacteria. Now, what about those llamas? Do llamas spit? Spacelocker: The happiest space on Earth
