While bacteria retain carbol fuchsin after acidalcohol trea

While _____ bacteria retain carbol fuchsin after acid-alcohol treatment, _____ bacteria are decolorized by acid-alcohol. gram-negative; gram-positive acid-fast, non-acid-fast non-acid-fast; acid-fast pathogenic: non pathogen

Solution

While acid-fast bacteria retain carbol fuchsin after acid alcohol treatment, non-acid-fast bacteria are decolorised by acid alcohol.

Carbol fuchsin is used as a dye to detect acid-fast bacteria because it is more soluble in the cell wall lipids than in the acid alcohol.
