Randomly amplified polymorphic DNA (RAPD) has been used for rapid typing of Lactobacillus plantarum strains. RAPD was used with either purified chromosomal DNA serving as template in the polymerase chain reaction, or with crude cell extracts, and using a 9-mer primer with 80% G+C content. Amplified DNA was visualized by ethidium bromide staining after separation on agarose gels. Patterns from 20 Lact. plantarum strains and two Lact. pentosus strains were analysed using the Pearson products moment correlation coefficient (r) and the unweighted pair group method with arithmetic averages (UPGMA). With some exceptions, the two sources of template DNA gave the same clusters and subclusters of strains at the similarity level of 50%. About 50% of the strains could be individually separated from all the other tested strains. The buffer brand, the amount of primer and crude cell extract used in the PCR-step were crucial for the final pattern.

UI MeSH Term Description Entries
D007778 Lactobacillus A genus of gram-positive, microaerophilic, rod-shaped bacteria occurring widely in nature. Its species are also part of the many normal flora of the mouth, intestinal tract, and vagina of many mammals, including humans. Lactobacillus species are homofermentative and ferment a broad spectrum of carbohydrates often host-adapted but do not ferment PENTOSES. Most members were previously assigned to the Lactobacillus delbrueckii group. Pathogenicity from this genus is rare.
D008969 Molecular Sequence Data Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
