Harvey Tatum worked for the Enteric and Special Bacteriology Sections of the CDC in Atlanta, USA. She was a microbiologist and bacteriologist who contributed greatly to the naming and understanding of the bacteria in the genus Tatumella. Tatum found vital information leading to scientists being able to tell whether or not a bacteria can ferment or not and how that is relevant in medical fields. The main name is named after Harvey Tatum, but there are also various strains, such as ptyseos and citrea, that have been classified over the years. Tatumella ptyseos was the originally discovered strain though. Information about Tatumella is relatively hard to find because there have been very few confirmed infections of it in humans.
The word Tatumella is a modern feminine latin noun, and the second part of the name, citrea, means citrus. This is included because the strain Tatumella citrea was found in Japanese orange trees.
