title: Probiotic lactobacilli and bacteraemia in Stockholm.
abstract: The objective of the present study was to determine the incidence of lactobacilli-induced bacteraemia in Stockholm, Sweden, between January 1998 and March 2004, and to identify the possible presence of probiotic strains. Isolated strains were checked for growth on selective lactobacilli-agar and the biochemical profiles were determined. The lactobacilli strains were further analysed with molecular methodologies to ascertain eventual similarities with the probiotic strains Lactobacillus paracasei subsp. paracasei F19 (LMG P 17806), Lactobacillus acidophilus NCFB 1748 and Lactobacillus rhamnosus GG (ATCC 53103). The minimum inhibitory concentrations of selected antimicrobial agents were determined by the agar dilution method. The incidence of bacteraemia cases caused by lactobacilli remained at the same level during the study period and constituted to <1% of the total number of bacteraemia cases each y. L. paracasei subsp. paracasei F19, L. acidophilus NCFB 1748 and L. rhamnosus GG were not identified in any of the samples.
