Co-infection ofHelicobacter pylori andEscherichia coli in a 4-year-old child

摘要

Helicobacter pylori (H. pylori) is a colonizer of more than half population worldwide among all age groups.Escherichia coli (E. coli) isolates are also colonizers of intestinal tract and several pathovars are important because of virulence factors leading to harm to the epithelial cells. A patient co-infected byE. coli andH. pylori was detected. TheELIZA kit and conventional biochemical tests were used for detection ofH. pylori andE. coli, respectively. A 4 years old girl was diagnosed for antiH. pylori immunoglobulin G and a high rate ofE. coli number (105CFU/mL) was determined in the stool examination. There was no data regarding familial history of infection withH. pylori. This girl had a history of hospitalization in Salmas hospital. Clinical findings included: fever, diarrhea, chilling and dizziness. Co-infection ofH. pylori andE. coli may complicate gastrointestinal disorders in children and if misdiagnosed or left untreated, there is the possibility of severe clinical outcomes.
