Objective: This study aimed to compare the prevalence and quantity of intestinal lactobacilli in constipated children and healthy controls. Methods: Forty children fulfilling Rome IV criteria for functional constipation and 40 healthy controls were recruited. Fecal samples were analyzed using species-specific polymerase chain reaction followed by random amplified polymorphic DNA-PCR and quantitative real-time PCR. Results: Totally, seven different species of lactobacilli were detected. Out of 80 volunteers, 65 (81.3%) were culture and species-specific PCR positive from which 25 (38.46%) constipated children and 40 (61.54%) healthy subjects. The most prevalent species were L. paracasei 21 (32.3%) followed by L. plantarum 18 (27.7%) among both healthy and patient groups. Analysis of the RAPD dendrograms displayed that strains isolated from constipated and non-constipated children have similarity coefficients of more than 90%. The qPCR assays demonstrated constipated children had a lower amount of total lactobacilli population (per gram of feces) than healthy controls. Conclusion: Our findings showed that the mere existence of various species of Lactobacillus in the gut does not enough to prevent some gastrointestinal disorders such as functional constipation, and their quantity plays a more important role.<\/jats:p>","DOI":"10.1590\/s0004-2803.202202000-44","type":"journal-article","created":{"date-parts":[[2022,7,6]],"date-time":"2022-07-06T12:05:35Z","timestamp":1657109135000},"page":"244-250","source":"Crossref","is-referenced-by-count":2,"title":["MOLECULAR
