No fungal elements were seen in the Gram stain, and the acid-fast stain using a concentrated Kinyoun stain was negative for acid-fast bacilli.
* No acid-fast bacilli seen (modified Kinyoun stain)
Kinyoun stain revealed oval asci with 1-4 ascospores inside, a characteristic finding of Saccharomyces genus (Figure 1(d)).
A modified acid-fast Kinyoun stain was also positive.
The purpose of this study was to detect and confirm the presence of acid fast bacilli in lymph node biopsies using routine Ziehl Neelsen stain, Kinyoun stain and fluorescence staining and also to determine the best, rapid and more cost effective technique of staining for the detection of acid fast bacilli.
Both patients had previously received a positive diagnosis by FSSM, which was confirmed by SSM with a modified Kinyoun stain. (9,11) The findings for one patient were reported as 1 + smear positive and for the other, as [3.sub.+] smear positive.
A cytospin slide prepared from the broth was positive for acid-fast bacilli by Kinyoun stain. The MGIT broth was subcultured to a Middlebrook 7H10/S7H11 agar biplate and incubated at 37[degrees]C in 5% C[O.sub.2] to obtain a pure culture of the organism for subsequent identification.
