Dear friend, welcome to HCM!
The gram stain and sputum culture
is normal for it shows only normally resident bacterial growth
which is normal.
Worry is about the growth of MAIS complex growth, which atypical tuberculosis
bacteria and are absolutely abnormal to have.
It indicates infection with Mycobacteria
Please see your physician or a pulmonologist for a detailed evaluation and correlating this culture finding with the clinical picture.
Also need to look for any lowered immunity state.
I hope Xray chest and other relevent tests are done.
Take care and please keep me informed of your progress.
I hope to have answered your query satisfactorily.
