-
a Doubling time: more than 120 min (score 0), between 90-120 min (score 1), between 60-90 min (score 2)
-
bAutoaggregation: no aggregation (score 0), presence of flakes (score 1), sedimented flakes but cloudy supernatant (score 2), sedimented flakes and clear supernatant (score 3).
-
c H2O2 production: strongly positive (score 3), intermediate positive (score 2) weakly positive (score 1), or negative (score 0) according to the intensity of blue colour development.
-
d Slight lysis of human blood cells were observed for 18R5 when grown in anaerobiosis.
-
e Presence (+) or absence (-) of plasmid
-
f Antibiotics to which the Lactobacillus strains are resistant among the 10 tested. Metronidazole (MHZ), cefoxitin (FX).
-
g Total score for a Lactobacillus strain is the sum of scores for doubling time, auto-aggregation and hydrogen peroxide production (max. value 8). Strains showing slight hemolysis (18R5) and presence of plasmid (5M8, 13B2, 15M7, 16B2) were scored 0.
- *Strains with the highest score selected for the clinical trial.
