✔✔b) quenching agent
A first morning sputum is received for culture of acid-fast bacilli. It
is digested and concentrated by the N-acetyl-L-cysteine alkali
method. Two Sabouraud dextrose slants are incubated in the dark
at 35ºC with 5%-10% CO2. The smear reveal acid-fast bacilli, but
the slants show no growth after 8 weeks. The explanation is: a)
improper media used b) incorrect concentration procedure used c)
improper specimen submitted d) exposure to CO2 prevents growth
- 🔰CORRECT ANSWERS ✔✔a) improper media used
MacConkey media for screening suspected cases of hemorrhagic E.
