[The prevention of malaria by ecologically safe methods]. / O profilaktike maliarii ékologicheski bezopasnymi metodami.

120 imported cases of malaria and 2 cases of malaria among the native population (1986-1987) likely infected by parasite carriers were registered over a period from 1970 to 1988 in Georgia. The attention has been focused on the planning of preventive measures. Parasitological service of the sanitary epidemiological stations is being improved. Population of anophelogenic reservoirs with the larvae-eating fish Gambusia (brought from Italy by N. P. Rukhadze in 1925) seems to be of great importance. Population of reservoirs with Gambusia is widely resorted to in Georgia. This measure has put an end to environmental contamination with insecticides. Complex preventive measures against malaria can ensure a stable situation with the disease in Georgia.

[Electron microscopic study of the morphology of Brucella and of the mechanism of their phagocytosis by blood cells]. / Elektronno-mikroskopicheskoe issledovanie morfologii brutsell i mekhanizma fagotsitoza ikh kletkami krovi.

Comparative electron microscopic investigations of Brucella were carried out in cultures in vitro and in vivo in guinea pigs with experimental brucellosis (blood) and in patients with brucellosis. Morphological differences in the structure of brucella due to different environments were found. The authors discuss facultative intracellular parasitism with intraphagosomal reproduction of the causative agent. This form of incompleted phagocytosis is a morphological manifestation of decreased defence properties of cells and causes the development of persistent infection with severe bacteriotoxemia. This is an important factor of the pathogenicity of this agent and underlies the pathogenesis of brucellosis.
