Abstract
A cloned 2-kb
Eco
RI fragment (fragment f) from a 34-kb plasmid of
Lactobacillus helveticus
CNRZ 1094 was shown by dot blot to specifically hybridize to total DNAs of 75
L. helveticus
strains. No hybridization was found with
L. acidophilus, L. crispatus, L. delbrueckii
subsp.
bulgaricus, L. delbrueckii
subsp.
lactis, L. gasseri
, or
L. intestinalis
strains. When Southern blots of
Eco
RI digests of
L. helveticus
strains were probed with fragment f, these strains displayed restriction fragment length polymorphisms on the basis of which they could be grouped into several clusters.
