Immediately after collection, all samples were taken to the bacteriology laboratory for bacteriological culture, primary gram stain, acid-fast stain, total white blood cell (WBC) and differential WBC count.
On day 2 of admission, sputum sample was sent for culture and acid-fast stain (AFB) staining, where numerous rhabditiform larvae of strongyloides (2-4/lpf) were observed, but acid-fast bacilli were not detected (Figures 1-3).
Compared to classic AFB staining, Fite's acid-fast stain uses a milder destaining acid, as well as less alcohol during the staining process, which it suitable for more delicate mycobacterium, such as leprosy bacillus [12].
Bone marrow examination with the Fite modification of the acid-fast stain is therefore indicated in such patients to evaluate marrow involvement and the efficacy of treatment.
Bacteriology got a significant jumpstart with the advent of certain tests, including the Gram-stain, acid-fast stain, and coagulase reactions, to name a few, that made it possible to separate the vast array of bacteria into manageable categories based on the anatomy of the organism and its source.
An acid-fast stain revealed numerous beaded, acid-fast bacilli in the keratin layers of the inflammatory exudate, and fewer bacilli within the inflammatory process of the marginal biopsy specimen (Fig 1).
