title: [Nitric oxide participation during amoebic liver abscess development].
abstract: Nitric oxide participates in both physiological and pathophysiological functions, and it plays an important role in the mammalian immune system in killing or inhibiting the growth of many pathogens, including parasites, viruses and bacteria. Entamoeba histolytica is a protozoan parasite that causes amoebiasis, which is characterized by intestinal damage and amoebic liver abscess development. The development of amoebic liver abscess in hamsters is similar to that in humans, whereas mice are resistant to amoebic liver abscess development due to an increase in nitric oxide production. Unlike in mice, amoebic liver abscess development in hamsters is due to an excess in nitric oxide production or possibly to a greater susceptibility of the hamster to damage caused by nitric oxide. Therefore, it could be important to elucidate if, in humans, an excess in nitric oxide production favors amoebic liver abscess development.
