A. Fernandezastorga et al., A USEFUL AND RAPID METHOD TO RECOVER BACTERIAL-CELLS FROM MILK SAMPLES FOR MICROSCOPIC COUNT, Journal of microbiological methods, 24(2), 1995, pp. 111-115
A description is given of a pre-treatment for milk samples which allow
s it to be filtered through 0.2 mu m pore-size membrane filters withou
t reducing the initial number of bacteria. The efficiency of the metho
d was demonstrated in milk samples inoculated with Escherichia coli O2
5:H-42, a food-borne pathogen, by comparison with a control in trypton
e soya broth (TSB). No significant differences were found between dire
ct microscopic counts in milk samples and controls in TSB.
