During intestinal and liver invasion by the protozoan parasite , extensive tissue destruction linked to large neutrophil infiltrates is observed. It has been proposed that microbicidal components of neutrophils are responsible for the damage, however, the mechanism by which they are released and act in the extracellular space remains unknown. In previous studies, we have shown that trophozoites induce NET formation, leading to the release of neutrophil granule content into extruded DNA.

Fulminant amoebic colitis is a rare complication of amoebiasis that carries a high mortality rate. Its diagnosis is challenging and requires a high index of suspicion, and its early recognition is a priority to provide timely medical and surgical treatment. We present the case of a male patient who came to the emergency department with unspecific clinical presentation of abdominal pain, systemic inflammatory response and imaging study showing intestinal perforation of the right colon.

Amoebic colitis, a parasitic infection caused by , can lead to severe gastrointestinal symptoms. The clinical manifestations can vary widely, from being an asymptomatic carrier to experiencing severe colitis and even colonic perforation. Surgical treatment for fulminant amoebic colitis and colonic perforation should be carried out at the earliest.

Cell migration modes can vary, depending on a number of environmental and intracellular factors. The high motility of the pathogenic amoeba Entamoeba histolytica is a decisive factor in its ability to cross the human colonic barrier. We used quantitative live imaging techniques to study the migration of this parasite on fibronectin, a key tissue component.

Introduction: Intestinal infections are a significant health issue; antibiotics are essential in treating acute intestinal infections. However, evidence in the literature shows that the excessive use of antibiotics has created many threats to human health. This work aimed to study the impact of apple pectin in combination with antibiotics on treating patients with amebiasis and dysentery.
