From the reviews: "The present volume reviews the most advanced knowledge about hepatitis by comparing this disease in humans and animals and describes the differences between the various etiologic agents. ... Overall, this cross disciplinary monograph provides extraordinary up to date information on the latest developments in hepatitis research and covers basic biology and biochemistry of pathogens as well as medical aspects and implications relevant for the general public health. No doubt, the book is an excellent resource for both fundamental research scientist and clinicians." (Norica Nichita, Romanian Journal of Biochemistry, Vol. 47 (1), 2010)
