title: Isolation of Mycobacterium avium-intracellulare-scrofulaceum complex from faeces of patients with AIDS.
abstract: Thirty faecal specimens from 22 patients with the acquired immune deficiency syndrome were examined by microscopy after Ziehl-Neelsen staining and by culture after decontamination with sodium hydroxide. Thirteen specimens (from 11 patients) were positive for Mycobacterium avium-intracellulare-scrofulaceum on culture, and only five of these on Ziehl-Neelsen staining. Five of the 11 patients had evidence of disseminated infection. Lipid analysis showed six of the nine strains tested to be indistinguishable. These findings support the theory that the gastrointestinal tract is a portal of entry for the organism.
