As per Falkow's original descriptions, the three postulates are: [1] "The phenotype or property under investigation should be associated with pathogenic members of a genus or pathogenic strains of a species. Specific inactivation of the gene(s) associated with the suspected virulence trait should lead to a measurable loss in pathogenicity or ...
Falkow is known as the father of the field of molecular microbial pathogenesis. [1] He formulated molecular Koch's postulates, which have guided the study of the microbial determinants of infectious diseases since the late 1980s. [2] Falkow spent over 50 years uncovering molecular mechanisms of how bacteria cause disease and how to disarm them. [1]
In 1988, microbiologist Stanley Falkow developed a set of three Molecular Koch's postulates for identifying the microbial genes encoding virulence factors. First, the phenotype of a disease symptom must be associated with a specific genotype only found in pathogenic strains. Second, that symptom should not be present when the associated gene is ...
Microbial pathogenesis is a field of microbiology that started at least as early as 1988, with the identification of the triune Falkow's criteria, aka molecular Koch's postulates.

There is no single generally accepted model for the origin of life. Scientists have proposed several plausible hypotheses which share some common elements. While differing in details, these hypotheses are based on the framework laid out by Alexander Oparin (in 1924) and John Haldane (in 1929), that the first molecules constituting the earliest ...
Their discoveries built a framework to understand the pathophysiology of pathogen-associated molecular patterns in HIV, [11] hepatitis C, [12] immune thrombocytopenia, [13] [14] and COVID-19. [15] [16] Peerschke studied both the collagen-like tail region of C1q, which binds calreticulin, and the receptor for the globular head of C1q, known as ...
He was promoted to associate professor in 1965 and to professor in 1967. He became the director of the microbiology department in 1972 and served in that position until 1982. In 1981, the department of microbiology was renamed the department of molecular biology and genetics.
