[Detection of coronavirus in experimental pneumocystic pneumonia].

Transmission electron microscopy (of ultrathin sections) was used to examine the biomass of lung tissue in the immunodeficiency minipigs experimentally infected with Pneumocystis carinii. The material was found to contain pneumocysts, bacteria, and coronaviruses. There was a clear coronavirus-pneumocyst structural relationship.

[Detection of markers of the human T-cell leukemia virus in patients with T-cell lymphoma and Kaposi's sarcoma].

Nine patients with Kaposi's sarcoma and five suffering from T-cell lymphoma have been examined. Antibodies to HTLV-1 were not found in these patients. The primary cellular cultures were isolated from blood and lymph nodes of the patients.

[The effect of interferon preparations on the ultrastructural organization of Legionella pneumophila].

The influence of the preparations of interferon on morphological changes in L. pneumophila on the ultrastructural level has been studied. Disturbances in the ultrastructure of L.

[The interaction of Legionella pneumophila with different types of cell cultures and the effect of interferon preparations on this process].

The interaction of L. pneumophila with lymphoblastoid cell cultures H9 and H9/IIIB and epithelial cell cultures HEp-2 mutual influence have been noted. L.

[A clinico-experimental study of patients with mycosis fungoides and Kaposi's sarcoma].

Twenty-six cultures were prepared by the cultivation method. Continuous cells lines (IK-10 and IK-12) were obtained in two cases, in the rest short-lived cell cultures were prepared. All the isolated cell cultures were studied by transmission electron microscopy.
