[Exotic pets as a potential source of Salmonella]. / Exotickí domáci milácikovia ako potenciálny zdroj salmonel.

STUDY AIM: To clarify the source of infection with the exotic serovar Salmonella Urbana and the route of transmission in a 2-year-old child. MATERIAL AND METHODS: To identify the source of infection and the route of transmission, we used epidemiological investigation of the case of salmonellosis and microbiological methods for the detection of Salmonella from biological specimens, epidemiologically suspected food, turtle tank water and feed, and serotyping of isolated strains of Salmonella. RESULTS: Salmonella Urbana was confirmed in a rectal swab of the infected child and in a sample of turtle tank water. Laboratory analyses of farm eggs eaten by the investigated family, of rectal swabs of the other family members and of a turtle feed sample did not reveal the presence of salmonellae. CONCLUSION: The confirmed source of Salmonella infection caused by the exotic serovar Salmonella Urbana in a two-year-old child were pet water turtles. In the case of the isolation of exotic serovars of Salmonella, the epidemiological and laboratory investigation needs to be aimed at the contact with pet animals, especially reptiles. It is desirable to raise the awareness of both the public and health professionals of this issue.

[Socioeconomic problems of worldwide population growth after the year 2000]. / K nekterým sociálneekonomickým problémum populacnho vývoje ve svete po roce 2000.

Demographic perspectives in the world are characterized by a trend towards stationary development in economically advanced countries and further growth, though relatively slower, in developing countries. In both instances we must foresee a trend of ageing in the age structure of the population after the year 2000, in the first phase in about 2010, in particular in European countries, and after 2025 in countries of the Third World. The foreseen development will be associated with various socio-economic problems the successful management of which makes it necessary to get ready for them already now. The most serious problems involve the adverse relation between the number of in1 active, dependent population and the number of economically active population. On the solution of this problem, by a marked increase of the productivity of labour, will depend the standard of life of the increasing number of population and the proportion of the population of postproductive age and finally of the whole population.
