[Differential diagnosis of paragonimiasis in relation to tuberculosis of the lung by transthoracic needle biopsy].

In a citizen of the People's Democratic Republic of Laos who has entered the German Democratic Republic for professional training a lung involvement in the shape of a circular focus was established after pleurisy. Hospitalization followed from suspected tuberculosis. Worm eggs of a lung fluke were parasitologically detected in a transthoracic fine needle biopsy.

[Trials for optimization of the culture conditions of human pathogenic trypanosomas and leishmania].

Due to the extended political, cultural and economic relations with tropical countries a good knowledge of tropical diseases is required. Since the direct parasitological diagnosis is superior to the serological one it seems logical to improve the culture conditions for laboratory diagnosis and for immunological and chemotherapeutical tests. Trypanosoma cruzi (Chagas) and Leishmania donovani (kala-azar) were tested in vitro.

[Differential diagnosis of introduced malaria].

It is reported on three cases of malaria tertiana and on one case of malaria quartana in combination with a peritoneal tuberculosis, emphasizing the differential-diagnostic problems.
