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.
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
Which organism is the most common cause of hematogenous osteomyelitis in sickle cell patients?a. Haemophilus influenzab. Staphylococcus aureusc. Group B streptococcid. Salmonellae. Bacillus anthracis
