Rezension

"This very readable book is a refreshing change from most books on parasitology. The authors provide a wonderful review of current research efforts and present it in a way to provide readers with useable information. They also delve into more futuristic ideas on parasite control by vaccination as well as genetic resistance and nutritional interactions." (Doody's, 23 September 2011)
 
"This is definitely a book for anyone who wants to know a lot of detail about gastrointestinal parasites of sheep and cattle, but not for those after a quick and definitive guide to solving common problems encountered in veterinary practice." (The Australian Veterinary Journal, January/February 2011)
