[Virologic research on the quality of 2 sources of drinking water from zone "I"]. / Investigations virologiques sur la qualité de deux sources d'eau potable de la zone "I".

Enteroviruses were isolated from 4.6% out of the examined tap water samples. No relation could be established between viral pollution and classic quality indexes of water.

Enterovirus contamination of swimming pool water; correlation with bacteriological indicators.

The investigation of swimming pool water samples revealed the presence of enteroviruses (in 28.4% of the samples), as well as of coliforms, fecal streptococci, staphylococci and Candida albicans (in proportions ranging from 37.0 to 86.9% of the samples). A direct correlation could be established between the extent of viral and microbial pollution and the length of stagnation of the swimming pool water.

[Epidemiological study of salmonelloses in the Moldavia area]. / Contributii la studiul epidemiologic al salmonelozelor pe teritoriul Moldovei.

A study was carried out on the epizooto-epidemiologic potential of certain domestic and wild animal species (cold-blooded), of the environment (residual waters) and food products, and their role in maintaining Salmonella endemics (others than the typhoid-parathyphoid group). Account was kept of the incidence of Salmonella and its circulation in subjects exposed to occupational risks and in the mass of the population, including those with clinically manifest salmonellosis and the clinically healthy carriers. The results showed the importance of domestic animals in maintaining the endemic (fowl 15%, swine 10%, bovine 5%). The isolated serotypes were identical to those found in residual eaters, in patients and in carriers. The sensitivity test to antibiotics revealed resistance to more than two antibiotics in 65%, except for the strains isolated from reptiles. Reorganization measures appear necessary in order to restrict the circulation of Salmonella in farm animals and to reduce the risks of infection in humans.
