Study Notes

Koch's Contributions

Robert Koch proved that Bacillus anthracis is responsible for anthrax in animals and humans.

Koch's Postulates

Establish a correlation between the pathogen and the disease by isolating the microbe from a diseased organism.
Cultivate the microbe in pure culture and demonstrate that it causes the same disease when introduced to a healthy host.
Re-isolate the microbe from the experimentally infected host to confirm the pathogenicity.

Biotic Disorders

Examples of biotic disorders include diseases caused by bacteria, viruses, fungi, and nematodes.

Disease Triangle

The disease triangle is also referred to as the 'pathogen-host-environment triangle', illustrating the interplay between these components in disease development.

Important Publication

The book 'Principles of Forest Pathology' was authored by Howard A. Ainsworth.
