Both bacteria appeared acid-fast by Ziehl–Neelsen stain and Gram-positive by Gram stain. The identification was performed by MALDI-TOF MS and gene analysis. N. brasiliensis and nontuberculous ...

Your doctor may use an acid-fast bacteria (AFB) stain test to see if you have a lung disease like tuberculosis (TB). In addition to showing tuberculosis, an AFB stain can also show if you have ...

Para-aminosalicylic acid (PAS) is one of the last remaining drugs available to treat extensively drug-resistant (XDR) tuberculosis. Good outcomes (81% 5 year survival) were documented when PAS was ...

The sensitivity and specificity of tNGS were benchmarked against a range of existing diagnostic approaches including hematoxylin and eosin (HE) staining in conjunction with acid-fast bacilli (AFB) ...

BACKGROUND Genitourinary tuberculosis (GUTB) results from hematogenous spread of chronic latent pulmonary tuberculosis of 5–40 years. 1 The diagnosis is typically delayed, as it can mimic a urinary ...

Figure 1: CT progression of patient’s sarcoidosis and tuberculosis. A) Initial adenopathy with peripheral patchy ground glass opacities in the right lung following COVID-19 pneumonia. B) Persistent ...

More than a million people die annually from tuberculosis, a bacterial lung disease. Volunteers could speed up the race for a TB cure that works for adults as well as children.

The only way to confirm disseminated TB is to ensure the presence of Mycobacterium tuberculosis, typically through an acid-fast smear or mycobacterial sputum stain.

Results showed that CBNAAT detected Mycobacterium tuberculosis (MTB) in 52 cases (8.77%) of the samples, while Ziehl–Neelsen stain identified acid-fast bacilli (AFB) in 21 samples (3.5%). Fluorescent ...

The samples are then heat-fixed and treated with an acid-fast stain for TB mycobacteria. Access to reproducible and high-throughput staining with these methods is limited by a lack of trained staff to ...
