causal

Examples of causal in the following topics:

• Koch's Postulates

  • Koch's postulates are four criteria designed in the 1880's to establish a causal relationship between a causative microbe and a disease.
  • Koch's postulates are four criteria designed to establish a causal relationship between a causative microbe and a disease.
  • Therefore, while Koch's postulates retain historical importance and continue to inform the approach to microbiologic diagnosis, fulfillment of all four postulates is not required to demonstrate causality.
  • Koch's postulates are four criteria designed in the 1880's to establish a causal relationship between a causative microbe and a disease.

• Experimental Epidemiology

  • Experimental epidemiology uses an experimental model to confirm a causal relationship suggested by observational studies.
  • The identification of causal relationships between these exposures and outcomes is an important aspect of epidemiology.
  • Although epidemiology is sometimes viewed as a collection of statistical tools used to elucidate the associations of exposures to health outcomes, a deeper understanding of this science is that of discovering causal relationships.

• Plant Pathogens

  • (causal agents of: canker rot, black root rot, Thielaviopsis root rot)
  • Magnaporthe grisea (causal agent of blast of rice and gray leaf spot in turfgrasses)

• The Science of Epidemiology

  • The identification of causal relationships between these exposures and outcomes is an important aspect of epidemiology.
  • Epidemiologists use gathered data and a broad range of biomedical and psychosocial theories in an iterative way to generate or expand theory, to test hypotheses, and to make educated, informed assertions about which relationships are causal, and about exactly how they are causal.

• Exceptions to Koch's Postulates

  • Therefore, while Koch's postulates retain historical importance and continue to inform the approach to microbiologic diagnosis, fulfillment of all four postulates is not required to demonstrate causality.

• Descriptive Epidemiology

  • The goal of epidemiology is to establish causal factors for health issues in order to improve the health and safety of entire populations.

• Koch and Pure Culture

  • Koch's research and methods helped link the causal nature of microbes to certain diseases, including anthrax.

• Identification of Microbes Based on Molecular Genetics

  • When sequence detection predates disease, or the sequence copy number correlates with severity of disease or pathology, the sequence-disease association is more likely to be a causal relationship.

• History of Microbiology: Hooke, van Leeuwenhoek, and Cohn

  • Based on these experiments, he devised criteria for establishing a causal link between a microbe and a disease and these are now known as Koch's postulates.
