Is staphylococcus aureus acid fast?
No, Staphylococcus aureus is not acid-fast. Acid-fast bacteria, like Mycobacterium tuberculosis, retain the stain when treated with acid-alcohol. Staphylococcus aureus is a Gram-positive bacterium that retains the crystal violet stain in the Gram staining method.
Does Mycobacterium smegmatis have endospores?
No, Mycobacterium smegmatis does not form endospores. Endospores are typically formed by some bacterial species in response to harsh environmental conditions as a survival mechanism, but Mycobacterium species, including M. smegmatis, do not produce endospores.
Does Mycobacterium smegmatis grow on bile esculin agar?
Mycobacterium smegmatis typically does not grow on bile esculin agar, as this medium is designed primarily for the isolation of Enterococcus and some other bile-tolerant organisms. Mycobacteria, including M. smegmatis, generally require specialized media for optimal growth due to their unique cell wall structure and nutrient needs. Therefore, while M. smegmatis might survive in some cases, it is unlikely to exhibit significant growth on this agar.
Did lactobacillus grow on mannitol salt agar?
Yes. M. smegmatis is a gram + bacteria, and MSA plates select for gram + bacteria.
Is M. tuberculosis acid fast or non-acid fast?
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....

Does mycobacterium smegmatis have flagella?
All Mycobacteria are non-flagellated. Originally thought to be non-motile, it has recently been discovered M. smegmatis and other species of Mycobacteria move using a sliding mechanism in which the organism flattens and retracts to move.
Did lactobacillus grow on mannitol salt agar?
Yes. M. smegmatis is a gram + bacteria, and MSA plates select for gram + bacteria.
Why is mycobacterium tuberculosis considered acid fast?
Saprophytic mycobacteria are acid fast and do not cause serious disease.
Could an acid fast organism be coccobacillus shaped?
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.
Is M. tuberculosis acid fast or non-acid fast?

Is a m and m an acid or a base?
A acid
What is a acid fast 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
What disease is an acid-fast bacilli smear used for diagnosis?
An acid-fast bacilli smear is commonly used for diagnosing tuberculosis, which is caused by the bacterium Mycobacterium tuberculosis. The test helps to identify the presence of acid-fast bacteria in patient samples, providing an initial indication of a possible tuberculosis infection.
What is the molarity of an unknown acid if 40.5 ml of the acid can be titrated to an end point by 20.5 ml of .2250 M NaOH?
The molarity of the unknown acid can be calculated using the formula: M acid x V acid = M base x V base. In this case, the molarity of the unknown acid is 0.112 M.
