The general class of disease caused by pathogenic bacteria invading and multiplying within host tissue, ranging from localized wound and skin infections to systemic, life-threatening conditions such as sepsis. This atlas records bacterial infection as a class alongside specific bacterial diseases, tuberculosis and cholera among them, which merit their own entities for their distinct histories and treatments; this entity is the general target of Louis Pasteur's and Robert Koch's germ theory work and of the subsequent development of antisepsis and antibiotics, addressed as a class of problem rather than one disease.

First Described (Era)
Antonie van Leeuwenhoek first observed microorganisms under a microscope in the 1670s, two centuries before their role in causing disease was established. 1

Antisepsis, Treatments

Antisepsis prevents bacterial infection of wounds and surgical sites rather than treating an infection already established. Joseph Lister's 1867 antiseptic method, using carbolic acid, dramatically reduced post-surgical infection and mortality.
