Question

Quizplus · Accepted Answer

Koch's postulates were developed for bacterial diseases and are not always applicable to viral diseases. Some viruses cannot be grown in pure culture, which is necessary for the isolation and identification of the infectious agent as required by Koch's postulates. Additionally, some viruses may not cause disease in all hosts or may cause disease in multiple hosts, which can make it difficult to establish a direct cause-and-effect relationship between the virus and the disease. Therefore, Koch's postulates are not easily satisfied for viral diseases.
