摘要

This study investigated the responses of Enterococcus faecium (ATCC 19433), Staphylococcus aureus (196E), and Listeria monocytogenes Scott A in water from a local meat-processing plant. Each bacterium was added to a starting count of 3 log_10 CFU/ml and held from 5 to 28 deg. C. At intervals (0, 2, 7, 14, and 21 days), aliquots were plated on appropriate selective agars. In contrast to the gram-negative bacteria studied previously and which grew, the three gram-positive bacteria survived with Some slight increase in number in only noncholorinated, reconditioned water, either filter (0.22 μm pore size) or nonfiltered.
