Evaluation of Anti-Quorum-Sensing Activity of Edible Plants and Fruits through Inhibition of the N-Acyl-Homoserine Lactone System in Chromobacterium violaceum and Pseudomonas aeruginosa
Abstract
Background: To find out an alternative strategy to antibiotic usage against bacterial infection. Materials and Methods: The purpose of this study is to describe the quorum-sensing (QS) inhibitory activity of edible plants and fruits against N-acyl-homoserine lactone (AHL)-mediated violacein production in Chromobacterium violaceum and virulence factor expression in Pseudomonas aeruginosa PAO1. Results: Aqueous extracts of Ananas comosus (Bromeliaceae), Musa paradiciaca (Musaceae), Manilkara zapota (Sapotaceae) and Ocimum sanctum (Lamiaceae) were prepared and anti-QS activity of each extract was tested against AHL-mediated phenotypic expressions of C. violaceum and PAO1. Most of these extracts showed significant reduction in AHL-mediated violacein production in C. violaceum as well as pyocyanin pigment, staphylolytic protease, elastase production and biofilm formation in PAO1. However, these extracts were not inhibitory to bacterial growth, revealing that the QS inhibition by the extracts is not related to static or killing effects on the bacteria. Conclusions: The present study identified the anti-QS activity of A. comosus, M. paradiciaca, M. zapota and O. sanctum. An AHL-inactivating compound from these plant sources can be used as an alternative to antibiotic compounds to prevent AHL-mediated bacterial infection in higher organisms.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
