Normally, I am not one to flash my credentials but this topic is just down my alley! I have a Masters degree in meat science and microbiology. I am aware of the "study" mentioned, and some other facts alluded to here but not with authority.
1. The study indicating wood has some bacteriostatic properties should not be used to extrapolate wood safety in the home or commercial establishment. Wood is still not allowed by USDA as a food contact surface. The bacteriostatic properties of "some" woods take hours to days while most woods have none at all. Cross contamination is the downside. You cut up a chicken on a wood cutting board, clean it (so you think!) and then chop salad greens on it. Can you spell "Salmonella?" Wood boards get small cuts in them, like plastic, and can harbor bacteria.
2. UHMW (ultra-high molecular weight plastics) and teflon make great cutting boards, are dishwasher safe and do not dull knives. BUY PLASTIC CUTTING BOARDS!
3. Acrylic, metal, ceramic, and glass are terrible on knives. Do not use them under your knives! If they can be used to sharpen knives, they can dull knives. A method for sharpening knives years ago was to strop it on the underside of a china teacup or saucer--the unglazed edge. You can also sharpen your knife on the top of your automobile window--just roll it down about half way and strop away.
4. A good sanitizer for boards and knives that have touched raw meat--especially poultry, is a teaspoon of liquid laundry bleach (Clorox) per gallon of water. When I cut chickens at home on my "PLASTIC" cutting boards, I put a little bleach in the dish water, or put them into the automatic dish washer. Automatic dish washer compound is made to be used at temperatures above 130 degrees F. It doesn't work well at temperatures your hands can stand. Also, it is very caustic--for cutting grease! All this means it is good for killing bacteria.
So take it from me. All you guys who are trying to justify your wood cutting boards, dump them! Buy plastic (UHMW or Teflon). Some of you won't believe me but remember this advice when you get severe cramps, diarrhea, severe head ache, etc. Sure, you can dodge the bullet for a while, but it will catch up with you eventually, and you won't like it!
Now I'll go back to sleep.
