Faeces from patients with Myco, tuberculosis in their sputum was decontaminated using NaOH, acid and an alkaline precipitation method. Treated specimens were diluted, to reduce the number of surviving normal flora, and cultured in liquid selective media. ⋯ Both alkaline methods were superior to acid treatment.
