[Significance of fecal streptococci in the detection of bacteriologic contamination of drinking water].

Because of their increased environmental resistance faecal streptococci are a good indicator of a contamination dating back a long time. Under the new Federal German Drinking Water Regulations, examination of faecal streptococci is not mandatory. On the basis of 190 samples of water from natural springs it was shown that, if the water was examined only in respect of E. coli and coliform bacteria there were no objections in 22% of water that was faecally contaminated, so that such water escaped detection. Hence, it is advisable to perform the faecal streptococci test in water that is frequently or potentially infected with bacteria.

[Hygiene certification of the Society for Proper Quality of Linen Care, Incorporated].

This is a survey of textile-technical requirements, of quality controls, of the hygiene certificate as well as of the relevant valid legal provisions, regulations and directions. The test-list for works inspection is quoted. The hygienic-bacteriological control methods as well as the checking methods are described by means of selected examples.

[Faecal streptococci as indicator organisms of drinking water].

The rules of the European Economic Community to harmonize the hygienic quality of drinking water write out the faecal streptococci as indicator organisms. This operating definition of the faecal streptococci prohibits its taxonomic limitation to enterococci or group D streptococci. Therefore, we have undertaken studies concerning the methods for routine examinations. Comparative investigations of selective enrichment broths showed no significant differences of the end concentration of glucose in the range of 0.5-1.0% and of sodium azide in the range of 0.02-0.05%. 36 degrees C was a better incubation temperature than 44 degrees C and the results were better after 24 h than after 48 h. Comparative investigations of selective plating media showed less selectivity of the bile-aesculin agar and gentamicinthallous-carbonate agar than that on the one hand of citrate-azide-tween-carbonate agar, KF streptococcal agar or Slanetz-Bartley enterococcal agar, and on the other hand of kanamycin-aesculin-azide agar. All together the kanamycin-aesculin-azide agar seems to be a little better than the other media (Table 2) 356 strains of faecal streptococci were isolated from the studied media. More than 20 characteristics were investigated and, there upon, the strains were differentiated (Table 3). S. faecalis predominates in human materials, i.e. urine, S. faecium and S. durans were isolated specially from sewage and waste water (Table 4). The single species of faecal streptococci grow specificly on the different selective media, and therefore, each agar specimen prefers the one or other species more or less selectively (Table 5).

[Hygiene problems in spas].

The problems of hygiene to be tackled in spas are governed by Federal German legislation such as the Federal Communicable Diseases Act, the Federal German DIN standard regulation No. 19643, the guidelines for the construction of medical baths and the legal definition of a spa. The article describes the problems of hygiene encountered in respect of the water in swimming pools and in physical exercise basins in spas, as well as the problems of hygiene in other fields with particular reference to microorganisms that are of special importance as far as hygienic aspects are concerned. Reference is made to the trihalogen methanes and to the problems in connection with the employed materials.
