Survey of antibiotic resistance of Pseudomonas isolatedfrom fresh cut red chicory (Cichorium intybus L., Asteraceae)

Risultato della ricerca: Articlepeer review


The present work was carried out to investigate the safetyaspects of minimally processed red chicory (Cichoriumintybus L., family Asteraceae) regarding the antibiotic resistanceof Pseudomonas Migula, 1894 populations (BacteriaPseudomonadaceae). The Pseudomonas strainstested for their characteristics were previously isolatedfrom experimental monovarietal salads prepared with twodifferent processes, a classic ready-to-eat (RTE) processand a process with entire leaves, and stored under refrigeration(4 °C) up to 15 days from production. Due to theirdominance over the microbial community, Pseudomonasstrains were better characterised for their undesirable featuresthat might be exerted on the health of consumers.To this purpose, the 21 dominant Pseudomonas strainswere subjected to the antimicrobial resistance test, applyingthe antibiotics commonly administered to combat intestinalbacteria responsible for human infections. Theresults revealed a certain sensibility to almost all the antibioticsdiffused among these bacteria, with the exceptionof ampicillin, amoxicillin, and chloramphenicol. If, onone hand, this study has found that, generally,Pseudomonas are not related to the dissemination of themajority of antibiotics used for hospitalized patients, onthe other hand, it poses the attention to this microbialgroup regarding ampicillin and amoxicillin.
