One of the major functions of mononuclear phagocytes, i.e., monocytes

obtain more insight into the pathogenesis of infectious diseases and
to develop new therapies against these diseases, a better understandin
g of the antimicrobial mechanisms employed by mononuclear phagocytes i
s essential. The present review gives a short description of the monon
