This illustration depicts a three-dimensional (3D), computer-generated image, of a group of Gram-positive, Streptococcus agalactiae (group B Streptococcus) bacteria. The photo credit for this image belongs to Alissa Eckert, who is a medical illustrator at the CDC.

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: "Cite error: Closing </ref> missing for <ref> tag A variety of factors contribute to this longevity, including a lack of genetically inherited disorders and beneficial diet and exercise choices earlier in life. However, another key biological factor has recently been linked to the medical resiliency of these long-lived individuals: their microbial gut composition. While aging is generally linked to a reduction in microbial diversity and ability to fight infection, analysis of the gut microbiome of centenarians has revealed trends in the relative abundance of specific consequential species compared to the general population.

Include some current research, with at least one figure showing data.
