The diversity of lactic acid bacteria occurring in the crop and intestinal content of ducks of different ages (5 to 34 days) was evaluated using the RAPD-PCR technique and comparative sequence analysis of 16S rRNA. Cluster analysis derived from isolates grown on Rogosa agar used for the enrichment of lactic acid bacteria, revealed at least twenty six different groups of organisms representing species, subspecies and strains belonging to Streptococcus, Enterococcus, Pediococcus, Weissella and Lactobacillus. Homofermentative and heterofermentative lactobacilli were identified, belonging to the phylogenetically defined Lb. acidophilus, Lb. salivarius and Lb. reuteri groups.
