Bacteria at Work

Bacteria at Work (吉田はるゆき) is a spin-off written and illustrated by Haruyuki Yoshida, and supervised by the author of the original, Akane Shimizu.

As of October 2018, there have been three volumes published.

Plot
The series is set in a world of anthropomorphic bacteria (instead of cells) living in a body. It focuses on the bacteria colonies living inside the intestines of a high school girl.

The portrayal of bacteria in this manga is different from the original, taking the form of humans living in an overall peaceful community instead of invading alien bodies.
