Comparison of fecal coliform agar and violet red bile lactose agar for fecal coliform enumeration in foods.
A 24-h direct plating method for fecal coliform enumeration with a resuscitation step (preincubation for 2 h at 37 +/- 1 degrees C and transfer to 44 +/- 1 degrees C for 22 h) using fecal coliform agar (FCA) was compared with the 24-h standardized violet red bile lactose agar (VRBL) method. FCA and VRBL have equivalent specificities and sensitivities, except for lactose-positive non-fecal colif...
متن کاملBoric acid lactose broth as a medium for the detection of fecal coliform bacteria.
Boric acid lactose broth has been suggested (Levine et al., 1934; Vaughn and Levine, 1935; Vaughn et al., 1951; Levine et al., 1955) as a medium for the detection of Escherichia coli in water and in foods. This medium is designed to suppress Escherichia freundii and species of Aerobacter, organisms often considered to be nonfecal in origin. The published results are rather convincing where sepa...
متن کاملComparison of Escherichia coli, Total Coliform, and Fecal Coliform Populations as Indicators of Wastewater Treatment Efficiency
Escherichia coli, total coliform, and fecal coliform population data were collected from two wastewater treatment facilities, a subsurface flow artificial wetlands, and a receiving stream. Results are presented from individual wastewater treatment process streams, final effluent, and river sites upstream and downstream of the treatment [ acilities. The QuantiTray technique with 4-mcthylumbellif...
متن کاملSynergistic false-positive coliform reaction on M-Endo MF medium.
The reported occurrence of synergistic false-positive coliform reactions on M-Endo MF medium was investigated. The objectives of the study were (i) to isolate populations of bacteria which produced such false-positive reactions, (ii) to determine whether false-positive sheen reactions are a result of synergistic interaction, and (iii) to determine the metabolic intermediates involved in false-p...
متن کاملCrystal Violet Agar as a Differential Medium for Staphylococci.
In a previous paper Chapman, Berens, Peters and Curcio (1934) showed that staphylococci could be differentiated on the basis of their hemolysis and coagulase reactions. It was further shown that a critical interpretation of the hemolysis test depended upon an accurate knowledge of the pigment production of the strain. The existence of intermediate-colored strains or of dissociants showing wide ...
