“…Moreover, as described in other studies (Hellberg et al, 2001;Branco et al, 2010;Srinivasan et al, 2010), G. vaginalis frequency was higher in patients with BV when compared to healthy women. However, when present in patients with BV, Lactobacillus levels were similar to those found in healthy women, suggesting that a beneficial effect of these bacteria depends not only on their presence in high quantities but also on their quality in term of protective ability.…”

“…Recently, our laboratory reported the production of synergistic and/or antagonistic compounds by G. vaginalis (Teixeira et al, 2010). In a second study, we confirmed the importance of high population levels of Lactobacillus (essentially Lactobacillus crispatus) and the quality of these lactobacilli as producers of antagonistic substances for a healthy vaginal environment (Branco et al, 2010). These results showed that the quantity of beneficial bacteria as well as their qualities as producers of antagonistic compounds seem to be pivotal factors in understanding BV and the ecological role of these bacteria in the vaginal environment.…”

“…Residual chloroform was allowed to evaporate, and Petri dishes were overlaid with 3.5 mL of a soft agar containing brain heart infusion (Acumedia, Neogen Co., Lansing, MI, USA), tryptone soy broth (Difco) supplemented with 0.5% yeast extract (Acumedia), or Ellinghausen–McCullogh–Johnson–Harris with Leptospira enrichment EMJH (Difco) inoculated with 0.2 mL of a 24 h culture of Staphylococcus aureus ATCC 29213, Enterococcus faecalis ATCC 19433, Pseudomonas aeruginosa ATCC 25853, Bacillus cereus ATCC 11778, Escherichia coli ATCC 25723, Salmonella enterica serovar Typhimurium ATCC 14028, Leptospira interrogans serovar Icterohaemorrhagiae , or Listeria monocytogenes ATCC 15313. After incubating at 37°C for 24 h under aerobic or anaerobic conditions, depending on the indicator strain, the antagonistic activity was determined based on the presence of a growth inhibition zone, using the method of Tagg as modified by Branco et al ., (2010) [100]. …”
