Mycobacterium tuberculosis is an acid fast bacterium. It has a high concentration of mycolic acids in the plasma membrane which prevent its staining by typical Gram stain methods. It must be stained with a procedure containing an acid decolorizing step to best visualize it under the microscope (Ziehl Nielson or Kinyon Methods). It resists decolorization with the acid, which is where the term "Acid Fast" comes from....
Acid-fast staining is used in determining tuberculosis. It can also track the progress of antibiotic therapy and determine how contagious a person is. Yay A&M microbiology lab!
Yes
No. in comparison to M. smegmatis which is acid fast positive. e. coli will appear blue when tested with the Zeihl-Neelsen acid fast stain
0.1 M strong acid is a better conductor than 1 M weak acid
in basic medium m-nitrobenzoic acid reacts with methanol to form methyl m-nitrobenzoate
Saprophytic mycobacteria are acid fast and do not cause serious disease.
Some diseases are leprosy ( M. leprae), tuberculosis (M. tuberculosis), and nocardiosis ( N. brasiliensis, N. asteroides). The acid fast stain is important in identifying bacteria in the genus Mycobacterium and Nocardia.M. tuberculosis

Yes an Acid fast organism could be coccobacillus shaped, eg. Mycobacterium avium, M. gordonae, M. montefiorense, Rhodococcus and even brucella species ( in modified cold acid fast staining) etc.
A acid
See your medical practitioner. They will most likely provide you with a sterile specimen container to collect a sample. This sample will then be sent to the laboratory for microscopy, culture, and sensitivity testing (M/C/S). If tuberculosis (TB) is suspected then acid-fast bacilli (AFB) will also be added to the request form.
yes. secondary tuberculosis which is more common in adult is actually the reactivation of the bacterial (M. Tuberculosis) which remain dormant in the lung after the first infection that can go back years ago.
