Abstract
Co-infection between Intestinal parasites and Helicobacter pylori (H. pylori) in humans is a frequent health problem,
particularly in developing countries. In addition to having similar risk factors, both pathogen groups are significant contributors to
gastrointestinal disease in those with these co-infections and can influence the host's immune response. Intestinal parasitic infections
are considered as a prevalent disease globally, affecting approximately 3.5 billion individuals, particularly in developing countries.
These infections can result in anaemia, growth retardation in children and other mental and physical health problems. H. pylori is
the most prevalent chronic bacterial infection in humans globally affecting about 4.4 billion individuals worldwide. H. pylori
infection is associated with chronic gastritis, peptic ulcers and development of gastric malignant tumors. Due to their similar modes
of infection and environmental conditions, intestinal parasites and H. pylori frequently co-infect each other. The objectives of this
review were to study the association between different types of intestinal parasites and H. pylori infection. Data was collected
scrutinizing PubMed using a mesh search. Initial word searches included Helicobacter pylori; Intestinal protozoa; Entameba
histolytica; Giardia lamblia; intestinal helminthes.
