en-abstract=The applicability of using enterococci and coli-form groups as indicators of water pollution was assessed. In human feces, enterococci were 10 times more numerous than coli-forms. Suspension of feces in sterile 0.85% NaCl solution at 25℃ did not result in enterococci growth. Coli-form groups, however, grew remarkably well. Enterococci were incapable of growth and died in filtration-sterilized river water. On the contrary, coli-form groups demonstrated significant growth. Tre pathogeneic enterobacteria (Sal. typhi, Sh. sonnei) died within four days, faster than enterococci. A 50-case field sample presented a correlation coefficient of +0.71 between the number of enterococci and coli-form groups. This indicated that enterococci and coli-form groups both serve as indicators of fecal water pollution. Enterococci numbered 2.3 times more than coli-forms. Coli-form group detection was not suitable for routine work, as it requires incubation at 45.5℃. These results indicate that enterococci are applicable for the indication of water pollution and more available than coli-form groups.
kn-abstract=腸球菌および糞便性大腸菌の水質汚染指標性の検討を行ない次のようなことが判明した.○人糞便中に腸球菌は糞便性大腸菌の約10倍多く存在していた.○糞便水を25℃におくと糞便性大腸菌は増殖したが,腸球菌は増殖しなかった.○メンブランフィルター濾過滅菌河川水中でE. coliは微小濃度の栄養源を利用しているものと考えられる増殖を示した.一方,消化器系 病原菌(Sal. typhi, Sh. sonnei)は4日程度ですみやかに死滅するが,腸球菌はそれよりやや遅く死滅する良好な生残性を示した.○野外調査を行ない河川水から腸球菌・糞便性大腸菌の検出を行なった結果, 50例による両者の相関係数は+0.71で糞便汚染指標菌として相関性があることが示され,量的には腸球菌が糞便性大腸菌の2.3倍多く検出された.○検査における手技の簡便性を考察すると糞便性大腸菌の検出は培養温度(44.5℃)の管理がわずらわしく,ルチンとしては不向きであると考えられた.以上のことから腸球菌は糞便性大腸菌よりも公共用水の汚染指標として有用であると結論された.
