Cost Postulate Basics
The Cost Postulate Basics is a fundamental concept in microbiology that aims to understand the relationship
between the cost of growing a pathogen and its ability to cause disease. It consists of four key factors in
disease causation:
Pathogen Presence in Diseases: The presence of a pathogen is crucial in causing a disease. However, not all
pathogens present in an organism will necessarily cause illness.
Pure Culture Growth in Lab: The growth of a pure culture of a pathogen in the laboratory setting is essential
to study its characteristics and virulence factors. This growth is often used as a benchmark for determining
the pathogen's ability to cause disease.
Disease Causation in Healthy Animals: A pathogen's ability to cause disease in healthy animals is a
significant factor in assessing its potential as a disease-causing agent. The more susceptible an animal is to
the pathogen, the more likely it is to cause disease.
Reisolation of Suspected Pathogen: The process of reisolating a suspected pathogen from an infected host is
critical in confirming its presence and role in causing the disease. This step helps to rule out other potential
causes of the illness.
The Cost Postulate Basics also consider exceptions and the molecular cost postulate, which explore the
limitations and nuances of the postulate in various disease-causing scenarios. Overall, the Cost Postulate
Basics provide a foundation for understanding the factors that contribute to a pathogen's ability to cause
disease and help microbiologists study and control disease-causing agents more effectively
