title: Isolation and electron microscopic observations of intracytoplasmic inclusions containing Chlamydia psittaci.
abstract: Intracytoplasmic inclusions containing Chlamydia psittaci were isolated by a newly established method. Infected L-cells at 20 h after infection were suspended in 0.25 M sucrose-tris(hydroxymethyl)aminomethane buffer containing ethylene-diaminetetraacetic acid, homogenized in a Dounce tissue grinder, and filtered through a 2,000-mesh screen. Isolated inclusions were stabilized in 5% bovine serum albumin in 10 mM tris(hydroxymethyl)aminomethane buffer. Electron microscopic observations revealed the presence of surface projections on the vegetative, reticulate bodies and a direct connection between the reticulate bodies and the inclusion membrane by means of projections.
