The following are the limitations of Koch's postulates EXCEPT: A. some pathogens cannot grow on artificial media and therefore cannot be identified as the causative agent of the disease B. some diseases involve multiple pathogens which produce similar symptoms making it difficult to pinpoint the causative agent C. some diseases are host-specific and re-inoculation may pose ethical concerns D. some microorganisms are present in the body fluids of the infected animal which make them difficult to be cultured

the following are the steps, listed in random order, for utilizing koch's postulates. what should be the second step out of the four listed? a. a microorganism is found to be present in every case of a disease. b. the same microbe discovered previously is isolated from the purposely infected host c. the pathogen is isolated and grown in pure culture d. the same disease results after isolated organism is inoculated into healthy host
Robert Koch developed a set of criteria (postulates) for conclusively demonstrating the aetiology (specific cause) of an infectious disease. Which of the following is not a postulate? The infectious agent must be isolated and cultured in vitro The disease is reproduced when a pure culture of the infectious agent is inoculated into a new susceptible host The infectious agent can be recovered from the experimentally-infected host The infectious agent is present in most cases of the disease
Which of the following is not a condition of Koch’s postulates?a. isolate the causative agent of a diseaseb. cultivate the microbe in a labc. inoculate a test animal to observe the diseased. test the effects of a pathogen on humans
Using the Koch's Postulates, support the findings that Mycobacterium tuberculosis is the causative agent of tuberculosis. Specifically, you have to provide brief narratives/pictures/proofs and sources that support the postulate listed below: The organism must be isolated from the newly infected animals and cultured again in the laboratory, after which it should be seen to be the same as the original organism.
Aside from the school laboratory facilities, How can we apply Aseptic Techniques in the following places as we are experiencing a Pandemic? A. Home EXPLAIN THE ANSWER.
When determining the clinical significance of cultures, a. the number of microbes is signifi cant. b. the presence of a single colony of a true pathogen may indicate the presence of the disease if the culture comes from a site known to be sterile (i.e., cerebrospinal fl uid). c. the repeated isolation of a relatively pure culture of any microorganism can mean it is an agent of disease, although this is not always the case. d. a range of tests may be needed to identify a pathogen. e. all of the above are true.
Koch's postulates is useful in describing diseases. True or false
a. List the main features of Koch′s postulates. b. Why is it so difficult to prove them for some diseases?
Which of the following is NOT true about Koch's postulates? First developed by Robert Koch, the pioneering German microbiologist In the first step, the microbe that causes a naturally occurring disease is cultured from a "wild" (non-laboratory) animal which has that disease None of the other four answers (All are true about Koch's Postulates) They represent a process for showing a causal association between a specific microbe and a disease If the same microbe from a diseased "wild" (non-laboratory) host causes the same disease in a lab animal and it can be cultured from that lab animal, this proves that the microbe is the cause of the naturally occurring disease
