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 کاملPerformance comparison of the BioSys optical assay and the violet red bile agar method for detecting coliforms in food products.
Coliform counts in a variety of foods, including dairy products (raw milk, pasteurized milk, yogurt, butter, and ice cream), meats (pork sausage, ground beef, and raw chicken), raw eggs, and chocolate, were performed by the rapid automated BioSys optical assay and the conventional method with violet red bile agar (VRBA). The standard deviation (SD) among five replicate counts for the optical as...
متن کاملSoil solarization reduces Escherichia coli O157:H7 and total Escherichia coli on cattle feedlot pen surfaces.
Feedlot pen soil is a source for transmission of Escherichia coli O157:H7, and therefore a target for preharvest strategies to reduce this pathogen in cattle. The objective of this study was to determine the ability of soil solarization to reduce E. coli O157:H7 in feedlot surface material (FSM). A feedlot pen was identified in which naturally occurring E. coli O157:H7 was prevalent and evenly...
متن کاملDiluent composition and the recovery of Escherichia coli.
The ability of 0.1% Trypticase (BBL) to maximize recovery of frozen Escherichia coli on Violet Red Bile Agar is presented.
متن کاملAtypical reactions of Escherichia coli on eosin methylene blue agar.
Evidence is presented that atypical reactions of Escherichia coli on eosin methylene blue agar are due to variations in pH in localized areas of the medium.
