A Collaborative Study of the Spiral Plate Method for Examining Milk Samples
Autor: James T. Peeler, Jeptha E. Campbell, C. B. Donnelly, James E. Gilchrist
Publikováno v: Journal of food protection. 40(7)
The spiral plating procedure is a rapid method for determining bacteriological counts. Results from a collaborative study indicate that the procedure should be useful in milk analysis. Typical milk samples (homogenized milk, raw milk, chocolate drink

Spiral plate count method for the examination of raw and pasteurized milk
Autor: Jeptha E. Campbell, C. B. Donnelly, James E. Gilchrist, James T. Peeler
Publikováno v: Applied and Environmental Microbiology. 32:21-27
The spiral plate count method (SPLPC) was compared with the standard plate count (SPC) method by examining 201 samples of raw and pasteurized milk. Although the means of the two methods differed significantly at alpha = 0.01,the difference was less t

CONTAINERS, REFRIGERANTS AND INSULATION FOR SPLIT MILK SAMPLES1
Autor: K. H. Lewis, L. A. Black, C. B. Donnelly
Publikováno v: Journal of Milk and Food Technology. 21:131-137
Methods are described for packing unfrozen split milk samples which hold their temperature within acceptable limits of 32–40°F for 24–30 hours when stored at ordinary room or higher temperature. The samples may be packed in a wrapped vacuum bott

A PLATE LOOP METHOD FOR DETERMINING VIABLE COUNTS OF RAW MILK1
Autor: C. B. Donnelly, D. I. Thompson, L. A. Black
Publikováno v: Journal of Milk and Food Technology. 23:167-171
A plate loop count method for determining viable counts of raw milk has been described. The technique uses a 0.001 ml calibrated loop attached to a continuous volume syringe for rinsing the sample into a standard petridish prior to pouring with agar.

Production of Enterotoxin A in Milk
Autor: L. A. Black, J. E. Leslie, C. B. Donnelly
Publikováno v: Applied Microbiology. 16:917-924
Enterotoxin A production in milk was studied by use of variables of milk quality, initial numbers of enterotoxigenic staphylococci, incubation temperature, and time. In both raw and pasteurized milks having a low total viable count, enterotoxin was d

Publikováno v: Journal of Milk and Food Technology. 35:136-140
Eighty-three samples of raw milk were assayed by the Standard Plate Count method with incubation periods of two and three days. The three-day incubation period gave higher counts (0.05 > p > 0.01). There were no appreciable problems (such as drying-o
