It is shown that infection of chick embryo fibroblasts with agents of paratrachoma and meningopneumonia Halprowiaceae (Chlamydiaceae) causes a sharp decrease of the activities of lysosomal enzymes, e.g. acidic alpha-glucosidase, beta-glucuronidase, beta-galactosidase, alpha-mannosidase, acid phosphatase, etc. The activity of cytosol enzymes (neutral alpha-glucosidase, amylo-1,6-glucosidase) does not change, however. A decrease in the activities of lysosomal enzymes in infected fibroblasts occurs some time later after inoculation and is due to a release of lysosomal enzymes from the fibroblasts into the culture medium, without loss of cell integrity. No changes in the activity of lysosomal enzymes in fibroblasts and culture medium is observed in the case of inoculation of cells with a killed agents, as well as after contact of cells with a suspension of normal chick embryo yolk sacs. The release of lysosomal enzymes from halprowiae-infected chick embryo fibroblasts probably occurs by the exocytosis.
