Popis: Objective: The current study investigated the additive effect of oral lead (Pb) exposure and dietary iron (Fe) deficiency on intestinal lactobacilli, E. coli, and yeast in SD rats. Methods: Weanling rats were fed on control diet (CD) or iron deficient diet (ID) for 4 weeks, followed by oral Pb exposure for another 4 weeks. Lead exposure was withdrawn for 2 weeks, and then resumed after 2 weeks. Blood samples were collected to determine haemoglobin (Hb), serum iron, blood Pb and δ-Aminolevulenic acid dehydratase (ALAD) activity. Fecal samples were collected to enumerate the lactobacilli, E. coli and yeast population on selective agar media and determine Pb levels. Results: Hb and serum Fe levels decreased significantly in iron deficient rats. Pb exposed rats had a significant increase in blood Pb levels and decreased ALAD activity. The lactobacilli population was significantly decreased (p
