Resumen
El objetivo de este estudio fue evaluar la capacidad inhibitoria de Lactiplantibacillus plantarum LP5 frente a Campylobacter coli enensayos de formación de biopelículas in vitro y exclusión competitiva. La formación de biopelículas por C. coli NCTC11366, C. coliDSPV458, C. coli DSPV541 y C. coli DSPV570 fue evaluada mediante medición de DO. La capacidad inhibitoria de L. plantarumLP5 frente a C. coli fue evaluada sobre discos de vidrio, nailon y aluminio. Sobre una biopelícula de L. plantarum se adicionó C.coli para cuantificar el efecto inhibidor de L. plantarum LP5 sobre el patógeno. Las cuatro cepas de C. coli fueron clasificadas comomoderadas formadoras de biopelículas. El ensayo de exclusión competitiva mostró que la formación de biopelículas de las cepasde C. coli en todos los materiales fue significativamente mayor que la formación de biopelículas de cada patógeno en presencia debiopelículas de L. plantarum LP5. Si bien es necesario realizar más pruebas para confirmar la capacidad de supervivencia de C. colien ambientes hostiles hasta llegar al huésped, este estudio permitiría avanzar en el esclarecimiento de su comportamiento mediantela formación de biopelículas.
The objective of this study was to evaluate the inhibitory capacity of Lactiplantibacillus plantarum LP5 against Campylobacter coli in in vitro biofilm formation and competitive exclusion assays. Biofilm formation by C. coli NCTC11366, C. coli DSPV458, C. coli DSPV541 and C. coli DSPV570 was evaluated by OD measurement. The inhibitory capacity of L. plantarum LP5 against C. coli was evaluated on glass, nylon and aluminium discs, added with L. plantarum and incubated at 37°C for 72 h. C. coli was added to each washed well. The plates were incubated at 42°C for 72 h in microaerophilic conditions and the biofilms were detached for quantification. The four strains of C. coli were classified as moderate biofilm former. e competitive exclusion test showed that the biofilm formation of the C. coli strains in all materials was significantly higher than the biofilm formation of each pathogen in the presence of L. plantarum LP5 biofilms. Although it is necessary to carry out more tests to confirm the ability of C. coli to survive in hostile environments until reaching the host, this study would allow progress in the elucidation of its behaviour through the formation of biofilms.
