Genes that satisfy molecular Koch's postulates are often referred to as virulence factors.
Although Koch's postulates are often inapplicable, they remain heuristic, and the authority of "fulfilling Koch's postulates" is still invoked in medical science, though often in modified form, [38] as in the identification of HIV-1 as the cause of AIDS or the identification of SARS coronavirus as the cause of SARS.

This paradigm was altered when Warren and Marshall effectively proved Koch's postulates for causation of PUD by H. pylori through a series of experiments in the 1980s; however, an extensive effort was required to convince the medical community of the relevance of their work.
January 7 – German microbiologist Robert Koch isolates Vibrio cholerae, the cholera bacillus, working in India.

Ogston demonstrated that these bacteria could be killed by heat or carbolic acid, fulfilling Kochs postulates.
