Humans have evolved throughout the many years with microbes. Microbes play an important role in not only human health but also human disease. The human intestinal tract contains a wide variety of microorganisms, all of which have a large impact on health and disease [1]. This microbiota has recently been studied more in depth as researchers discovered that microbes have a larger impact on human health than once understood. Antibiotics and diet have been shown to alter the diversity of the gut microbiota, leading to the possibility of irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) since patients with IBS and IBD have been shown to have unstable gut microbial populations [2].

Sample citations: [1] [2]

A citation code consists of a hyperlinked reference within "ref" begin and end codes.
To repeat the citation for other statements, the reference needs to have a names: "<ref name=aa>"
The repeated citation works like this, with a forward slash.[1]
