Web1 feb. 2014 · In mycobacteriology, auramine-phenol has mostly replaced Kinyoun’s acid fast stain because of the ease of interpretation. 17 However, Kinyoun’s acid fast stain was considered the best method for diagnosing coccidia in fecal samples, as auramine-phenol stain has been reported to yield ambiguous results when used to screen for coccidia. 17 WebOocysts of Cyclospora in clinical specimens are routinely demonstrated using modified acid-fast stain (cold). However, with that technique, the oocysts stain variably from nonstaining to full staining leading to possible misidentification. The modified safranin technique produces a more uniform staining of these oocysts. Web6 jul. 2024 · Acid-fast staining was developed by Robert Koch in 1882 and later modified by other scientists. Koch used the method to observe the “tubercle bacillus”—what we now call Mycobacterium tuberculosis, in sputum samples. While acid-fast and gram staining are both differential stains, the acid-fast stain is much more specific. thitirat siriborvornratanakul
