“…Revision of their full texts allowed selection of 31 reports that raised safety concerns, all of which described human pathological processes. The claimed aetiological agents comprise L. acidophilus (Cohen et al., ; Haghighat and Crum‐Cianflone, ; Hubbard et al., ), L. animalis (Somayaji et al., ), L. casei (Passera et al., ; Vanichanan et al., ; Pailhories et al., ; Stroupe et al., ; de Seynes et al., ), L. coryniformis (Datta et al., ), L. delbrueckii (Chaini et al., ; Maillet et al., ), L. gasseri (Chaini et al., ; Elikowski et al., ; Esquibel et al., ), L. paracasei (Harding‐Theobald and Maraj, ; Kao et al., ; Kato et al., ; Pararajasingam and Uwagwu, ), L. plantarum (Biesiada et al., ), L. rhamnosus (Felekos et al., ; Molinaro et al., ; Aaron et al., ; Norena et al., ; Boumis et al., ; Kane et al., ; Koyama et al., ; Naqvi et al., ; Nayeem et al., ; Zeba et al., ) and L. salivarius (Garcia Carretero et al., ; Wang et al., ).…”

The qualified presumption of safety (QPS) was developed to provide a safety pre‐assessment within EFSA for microorganisms. Strains belonging to QPS taxonomic units (TUs) still require an assessment based on a specific data package, but QPS status facilitates fast track evaluation. QPS TUs are unambiguously defined biological agents assessed for the body of knowledge, their safety and their end use. Safety concerns are, where possible, to be confirmed at strain or product level, and reflected as ‘qualifications’. Qualifications need to be evaluated at strain level by the respective EFSA units. The lowest QPS TU is the species level for bacteria, yeasts and protists/algae, and the family for viruses. The QPS concept is also applicable to genetically modified microorganisms used for production purposes if the recipient strain qualifies for the QPS status, and if the genetic modification does not indicate a concern. Based on the actual body of knowledge and/or an ambiguous taxonomic position, the following TUs were excluded from the QPS assessment: filamentous fungi, oomycetes, streptomycetes, Enterococcus faecium, Escherichia coli and bacteriophages. The list of QPS‐recommended biological agents was reviewed and updated in the current opinion and therefore now becomes the valid list. For this update, reports on the safety of previously assessed microorganisms, including bacteria, yeasts and viruses (the latter only when used for plant protection purposes) were reviewed, following an Extensive Literature Search strategy. All TUs previously recommended for 2016 QPS list had their status reconfirmed as well as their qualifications. The TUs related to the new notifications received since the 2016 QPS opinion was periodically evaluated for QPS status in the Statements of the BIOHAZ Panel, and the QPS list was also periodically updated. In total, 14 new TUs received a QPS status between 2017 and 2019: three yeasts, eight bacteria and three algae/protists.

“…offering anti‐microbial activity versus being the culprit in joint infections. Recent case reports discuss Lactobacillus as the pathogen in septic arthritis, limb amputations and chronic PJIs 28,75‐77 . Nevertheless, use of the CFS or identification and isolation of the active compounds therein may hold promise for its future use in the prevention and treatment of orthopedic infection.…”

Lactobacillus cell‐free supernatant as a novel bioagent and biosurfactant against Pseudomonas aeruginosa in the prevention and treatment of orthopedic implant infection

The hypothesis was that probiotic Lactobacillus species (spp.) or their cell‐free supernatant (CFS) are effective in inhibiting (a) planktonic growth of Pseudomonas aeruginosa (PA), (b) its adhesion to a Ti6Al4V‐alloy surface, and (c) in dispersing biofilm once formed. (a) A planktonic co‐culture containing PA(104 colony‐forming unit [CFU]/ml) was combined with either Lactobacillus acidophilus, Lactobacillus plantarum (LP), or Lactobacillus fermentum (LF) at a suspension of 104 (1:1) or 108 CFU/ml (1:2). Lactobacillus and PA CFUs were then quantified. (b) Ti‐6Al‐4V discs were inoculated with PA followed by supplementation with CFS and adherent PA quantified. (c) Biofilm covered discs were supplemented with Lactobacillus CFS and remaining PA activity quantified. Results showed that whole‐cell cultures were ineffective in preventing PA growth; however, the addition of CFS resulted in a 99.99 ± 0.003% reduction in adherent PA in all Lactobacillus groups (p < .05 in all groups) with no viable PA growth measured in the LF and LP groups. Following PA biofilm formation, CFS resulted in a significant reduction in PA activity in all Lactobacillus groups (p ≤ .05 in all groups) with a 29.75 ± 15.98% increase measured in control samples. Supplementation with CFS demonstrated antiadhesive, antibiofilm, and toxic properties to PA.
