[Aspects of the etiological diagnosis of extrapulmonary tuberculous infections].

An analysis is made of criteria used for making an etiologic diagnosis of extra-pulmonary tuberculosis over a period of 15 years, and a general correlation is noted between the figures for morbidity and those of bacteriologic confirmations. In the group of patients which has been investigated the diagnosis could be ascertained from urine samples in 44% of the cases, from lymph-nodes and nodules in 15% from pleural fluids in 14%, from purulent collections in 13%, and from the cerebrospinal fluid in 8% of the cases. Human type mycobacteria was evidenced in 90% of the cases.

[Bacteriological and epidemiological observations on atypical mycobacteria isolated at the laboratory of the Cluj-Napoca Tuberculosis Hospital].

Excluding cases of clinically manifest mycobacteriosis atypical mycobacteria can be detected in the excreta of healthy subjects, of tuberculous patients, or of other patients suffering from other diseases, without any major clinical implication. In certain environment conditions however epidemiologic manifestations may be induced by these organisms, of the hospitalism type. Atypical strains of the mycobacteria isolated over a period of 10 years represent 3.
