| Background: Co-infection with intestinal parasites and Helicobacter pylori is a common infection, particularly in developing countries. This study aimed to evaluate the prevalence of intestinal parasites in patients with and without H. pylori infection who presented with gastrointestinal symptoms in Mosul city. Methods: Two biopsy specimens were collected from each of 100 patients (both sexes) presenting with symptomatic abdominal pain between August 2024 and March 2025. Using endoscopic forceps under aseptic conditions, the first specimen was obtained from the gastric region for histopathological and molecular analysis to confirm the presence of Helicobacter pylori. The second specimen was taken from the duodenum to detect intestinal parasites. Results:The study recorded Helicobacter pylori infection rates of 76% and 60% using histological examination and polymerase chain reaction (PCR), respectively. Sixty PCR-positive samples for H. pylori were further tested for intestinal parasites to evaluate co-infection. A high overall co-infection rate of 55% was observed, with some patients harboring multiple intestinal parasites. Among the co-infections, Giardia duodenalis was the most prevalent 28.33%, followed by Entamoeba histolytica (26.66%) and Blastocystis hominis 20%. Co-infection rates by sex were 28.33% in males and 26.66% in females. The age group most affected was 15–30 years 25%, followed by 30–45 years 11.66% and 45–60 years 11.66%. The lowest co-infection rates 3.33% were recorded in patients younger than 15 years and in those aged 60 years or older. In terms of residence, co-infection was more common in rural areas 30% than in urban areas 25%. Conclusion: The highest prevalence of coinfection H. pylori with intestinal parasites, especially Giardia duodenalis. | ||
