What have we learned from brucellosis in the mouse model?
(Veterinary Research, 2012)Brucellosis is a zoonosis caused by Brucella species. Brucellosis research in natural hosts is often precluded by practical, economical and ethical reasons and mice are widely used. However, mice are not natural Brucella ... -
What Is the Evolutionary Fingerprint in Neutrophil Granulocytes?
(University of Veterinary Medicine Hannover, Hannover, Germany, 2020-06-25)Over the years of evolution, thousands of di erent animal species have evolved. All these species require an immune system to defend themselves against invading pathogens. Nevertheless, the immune systems of di erent ... -
