Giardia intestinalis and Blastocystis spp. are two common zoonotic intestinal parasites responsible for the majority of diarrheic cases, especially in children. The study was planned to determine the impact role of both Giardia and Blastocystis co-infection in children up to 12 years old with acute diarrhea in Beni-Suef, Egypt. Also, to estimate the general prevalence rates and risk factors associated with intestinal parasitic infections. Stool samples collected from 125 children, within a period of 7 months, were examined using direct wet mount and trichrome stain in comparison to in vitro culture on Jones medium (for detecting Blastocystis spp.) and Immunochromatography techniques (for detecting Giardia). At least one type of intestinal parasites was harbored in 72% of the studied children, single infection constituted 37.6% while, 34.4% were polyparasitized children. The predominant parasites involved were Blastocystis spp.(53.6%), followed by Giardia intestinalis (27.2%). Co-infection between both parasites was recorded in 20% of cases. Two risk factors were significantly associated with higher risk of Giardia-Blastocystis co-infection including age category (5–7 years) and family size (≥ 6 members) by univariate analysis (P = 0.004, 0.009 respectively) and also by the multivariate model (OR = 0.526, 0.336). Abdominal pain was the only gastrointestinal manifestation associated with the co-infection using the univariate analysis (P = 0.0427). The present study detects a high prevalence of intestinal parasitic infection; in particular, Giardia-Blastocystis co-infection in diarrheic young children (up to 12 years) in Beni-Suef Governorate, Egypt and recommends further subtypes identification of both parasites.
