Abstract
Enteric infections, whether accompanied by apparent diarrhea or not, significantly impact gastrointestinal absorption, nutrition,
childhood development, and global mortality rates. This study attempts to answer the question (Is there co infection
between E. histolytica and E. coli in diarrheal samples?). This study, conducted from October 2024 to January 2025 in
Al-Rifai and Al-Nasiriyah in Thi-Qar, province the possible co-infection of E. histolytica and E. coli in 130 diarrheal
patients. The samples were examined by direct examination. The findings reveal a correlation between the parasite and
the bacterium in Al-Rifai and Al-Nasiriyah districts.The infection prevalence of E. histolytica was 66 out of 130
(50.76%). Conversely, 54 out of 130 (41.53%) E. coli showed positive culture growth confirmed by morphological
characteristics. However, 28/130 (21.53%) were found to be positive for both pathogens. It is clear that the co-existence
of these two pathogens follows the same trend (both were highly prevalent in the age group (> 20 years old), the coexistence
of the two pathogenesis was higher in Al-Refai than in Al-Nasiriyah (28.94% vs.71.06%). Conclusions, there
is co infection between E. coli and E. histolytica in the two districts.
