In vitro probiotic properties of Pediococcus pentosaceus L1 and its effects on enterotoxigenic Escherichia coli-induced inflammatory responses in porcine intestinal epithelial cells.

Abstract
This study aimed to evaluate in vitro probiotic characteristics of Pediococcus pentosaceus strain L1 from pickled radish and investigate its impacts on inflammatory responses in porcine intestinal epithelial cells (IEC) to enterotoxigenic Escherichia coli (ETEC) F4+. The abilities of P. pentosaceus L1 to tolerate gastrointestinal conditions and to antagonize ETEC F4+ growth were determined. Adhesion of P. pentosaceus L1 and its effect on ETEC F4+ adhesion to porcine IPEC-J2 IEC were evaluated. Furthermore, the effects of this strain on proinflammatory gene expression and cytokines/chemokine production in porcine IPEC-J2 IEC induced by ETEC F4+ were determined. P. pentosaceus L1 showed good tolerance to the medium adjusted at pH 2.5 and consequently supplemented with 0.3% oxgall. Reduction of ETEC F4+ growth in co-culture with L1 was found. Effective adhesion of L1 to porcine. IPEC-J2 IEC was observed under these conditions. P. pentosaceus L1 decreased the adhesion of ETEC F4+ to IPEC-J2 IEC and the extent of inhibition of ETEC F4+ adhesion depended on the timing of L1 addition. Further analysis revealed down-regulation of expression of ETEC F4+-induced proinflammatory genes encoding interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and interleukin-8 (IL-8) in IPEC-J2 IEC. Expression of the genes involved in NF-κB pathway, including RELA and NFKB1, were also repressed, as was production of IL-6, TNF-α, and IL-8. These results indicate that P. pentosaceus L1 may have potential as a probiotic for control of ETEC infection in pigs.

Antibiotic susceptibility profile of Pediococcus spp. from diverse sources. 3 Biotech 2018; 8:489. [PMID: 30498662 DOI: 10.1007/s13205-018-1514-6] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2017] [Accepted: 11/13/2018] [Indexed: 10/27/2022] Open
Abstract
The aim of the present study was to assess the antibiotic susceptibility profile of Pediococcus strains from diverse sources. From a total of 115 dairy and non-dairy samples, 40 Pediococcus strains were isolated. Their biochemical and molecular characterization confirmed them as P. pentosaceus and P. acidilactici. All the 40 identified isolates were evaluated for antibiotic susceptibility using disc diffusion assay against a total of 20 antibiotics. The isolates exhibited varied range of responses towards the antibiotics depending on the strain type, source and location of isolation. All the isolates were either sensitive or intermediate resistant to amoxycillin, erythromycin, ceftriaxone, cloxacillin, cefoperazone, penicillin, netillin, gentamycin and chloramphenicol. Resistance towards vancomycin and nalidixic acid was exhibited by most of the isolates. A total of 16 strains belonging to dosa batter (n = 4; n = number of isolates), fermented vegetables (n = 4), fermented grape juice (n = 4), idly batter (n = 3) and the only isolate from butter milk exhibited sensitivity/intermediate towards 80-90% of the studied antibiotics. No considerable difference in susceptibility pattern was observed between the two Pediococcus species, i.e., P. pentosaceus and P. acidilactici. Overall, the maximum resistance was exhibited by isolates belonging to silage (Sil-2; 50%) followed by cow milk (PD-41), dosa batter (8-PD) and human isolate (PD-45) which showed resistance towards 40% of studied antibiotics. The susceptibility profiling of Pediococcus strains will be helpful in their safer selection for future food and feed applications.
