Physicians need to alert the laboratory when they suspect Cyclospora so that a modified acid-fast stain can be performed.

With the acid-fast stain, these illnesses would be misidentified as TB and, in most instances, also would be reported as treatment failures.

Morphologic characteristics, together with negative routine acid-fast stains (Ziehl-Neelsen, auramine-rhodamine), differentiate nocardia from mycobacteria.

Eight patients had no sputum specimens submitted for acid-fast stain and culture.

Lesions can be screened for mycobacteria using an acid-fast stain.

However, direct and acid-fast stain microscopic examination of stool specimens from nine of the house staff physicians and one of the other employees revealed the presence of CLB.

A direct acid-fast stain showed many acid-fast bacilli.

They were stained with Kinyoun's carbol fuchsin modified acid-fast stain and examined by oil immersion microscopy.

parvum oocysts were processed with acid-fast stain (AFS) (8) to check for normal cellular morphologic features.

To confirm the presence of acid-fast bacteria, tissue sections were stained using multiple commercially available acid-fast stains (Fite's Stain Kit, American Master Tech Scientific Laboratory Supplies, Lodi, California; Kinyoun's Stain, Gibson Labs, Lexington, Kentucky; Ziehl-Neelsen Stain, Gibson Labs, Lexington, Kentucky).

Smears performed from the colonies revealed Gram-positive microorganisms; partially acid-fast stains (modified Kinyoun acid-fast) were also positive (Figure 2) but Kinyoun stains were negative in all isolates.

However, no recent studies have been published that evaluate the sensitivity of modified versus standard acid-fast stains for diagnosis of cutaneous RGM infections.

Microbiology stainers provide high-quality Gram staining and different natural or fluorescent acid-fast stains for mycobacteria.

Currently, definitive diagnosis of mycobacteriosis in birds is accomplished by demonstrating organisms in organ biopsy or aspirate samples with acid-fast stains, culture, or molecular methods.
