[Clinical findings in patients with lung diseases caused by non-tuberculous mycobacteria in former East Germany and Hungary].

The importance of lung diseases caused by nontuberculous mycobacteria is increased. Clinical findings in 54 patients of the former GDR and 110 patients from Hungary were investigated. Most of the patients were men in average age of 55 years.

[Lung diseases caused by non-tuberculous mycobacteria in East Germany and Hungary].

Despite the decrease of new cases of pulmonary tuberculosis also between 1982 and 1986 an increase in nontuberculous mycobacteriosis can be seen especially in the GDR and also in Hungary. In 1986 the ratio of recognized lung diseases caused by nontuberculous mycobacteria to all newly diagnosed bacillary cases was 4.1% in the GDR and 2.

Effect of deep freezing on the result of blood cultures.

From citrated blood samples left to stand in the deep freeze at -20 degrees C for 12--14 hr prior to culturing, Staphylococcus aureus was recovered more effectively than from the control cultures.

WHO cooperative studies on the phage-typing of mycobacteria. 1. Phage lysis of Czechoslovak and Italian strains of Mycobacterium tuberculosis.

Although phage-typing of some pathogenic microbes-e.g., Escherichia coli and the genera Salmonella, Staphylococcus, and Streptomyces-is in routine use, little progress has yet been made in the phage-typing of mycobacteria, chiefly because mycobacteriophages possess a polyvalence that prevents the reliable identification of individual species of mycobacterium.
