On the other hand, LAB contaminate milk and meat
obtained from animals that have been treated with
antibiotics and so carry populations of resistant bacteria
(Teuber et al., 1999). It is possible for this resistance to
be transmitted to the human population through the
food chain. Although many strains are not pathogenic,
they could constitute a reservoir of genes conferring
resistance to antibiotics which might be transferred to
pathogenic strains (Luka´ sˇova´ and Sˇ usta´ cˇkova´ , 2003).
