Why is Mycobacterium tuberculosis not seen on Gram stained smears?
tuberculosis has an unusual, waxy coating on its cell surface primarily due to the presence of mycolic acid. This coating makes the cells impervious to Gram staining, and as a result, M.
Can psoriasis cause tuberculosis?
These cases highlight the possible role of tuberculosis infection in the pathogenesis of psoriasis, suggesting the possible existence of a link between untreated infection and skin lesions. This can lead to consideration of novel therapeutic strategies and new lines of investigation.
Can latent TB cause psoriasis?
Applying LTBI diagnosis guidelines, latent infection resulted in more psoriasis (50%) than inflammatory bowel disease patients (24.2%), prior to onset of any anti-TNF-α treatment (P = 0.04) [42].
How is cutaneous leishmaniasis diagnosed?

What is the difference between visceral and cutaneous leishmaniasis?
Some species cause visceral leishmaniasis, some cause cutaneous disease, and some cause both.
