Significance of coliforms and enterococci in fish products.
Coliforms, more recently fecal coliforms, and enterococci are often used to assess the hygienic quality of foods. Although these bacteria serve rather successfully as an index of fecal pollution of water supplies, their usefulness in measuring fecal pollution in foods is less than satisfactory. The ratio and correlation of coliforms and enterococci in fish-fillet and lobster-meat samples led us...
متن کاملColiforms, enterococci, thermodurics, thermophiles, and psychrophiles in untreated farm pond waters.
Untreated waters from ten farm ponds located in central, north central, southeastern, and southwestern Ohio were examined for numbers of coliforms, enterococci, thermodurics, thermophiles, and psychrophiles. The median population densities per 100 ml water for all ponds were: coliforms, 23; enterococci, 3.6; thermodurics, 6,000; thermophiles, 450; psychrophiles, 1,000. The results indicate that...

15 صفحه اولPlating procedure for the enumeration of coliforms from dairy products.
A "repair-detection" procedure consisting of pour plating of food samples with Trypticase soy agar, followed by 1-h repair incubation at room temperature and subsequent overlay with violet red bile agar, was found to be an effective method for the detection of injuried and uninjuried coliforms from dairy products. This method was relatively less effective for the detection of coliforms in many ...
