摘要

In this study, vancomycin-resistant enterococci (VRE) from humans and vancomycin-resistant gram-positive cocci (VRPC) from pigs were examined for their ability to transmit in the chick intestine (Experiment 1). A model study on the spread speed of VRPC was also estimated from chick to chick under semi-production conditions with different administration routes (not inoculated, oral administration to a chick, sprayed on the floor) (Experiment 2). Furthermore, the disappearance of VRPC from their litter with composting processes was examined (Experiment 3). Each of six chicks was inoculated with VRPC or VRE at 1 day old in Experiment 1. All the chicks had VRPC or VRE in their glandular stomach at 22 days of age. In Experiment 2, 6 floor pens covered with sawdust were prepared and 20 chicks were allotted to each pen. The chicks were inoculated with VRPC at 1 day of age. The VRPC were detected in each group in cloacal swabs at 2 days of age (detection rate; 20-80%). And they were also detected in the not-inoculated group. The VRPC detection rate gradually decreased, and detection was rare (0-10%) in the packing chicks (50 days old). VRPC were detected in the litter of each pen in Experiment 2. A composting process was effectively used to eliminate VRPC by the 6th week (Experiment 3)..
