À propos du comportement de butinage de Megachile sculpturalis Smith, 1853, en France méditerranéenne (Nîmes et Montpellier) (Hymenoptera, Megachilidae)
PERSÉE : Université de Lyon CNRS & ENS de Lyon, 2018Co-Authors: Andrieu-ponel Valérie, Ponel Philippe, Le Féon Violette, Geslin Benoît, Duvallet GérardAbstract:About the foraging behavior of Megachile sculpturalis Smith, 1853, in Mediterranean France (Nîmes and Montpellier) (Hymenoptera, Megachilidae). The study of the pollen content of two samples taken, either on one specimen of Megachile sculpturalis Smith, 1853, or in the lodge of an “ insect hotel” frequented by this Hymenoptera, gives preliminary indications on the behaviour of foraging and on the diet of this invasive bee whose first observation in France dates back to 2008. The dominance of pollen assemblages by the pollen of Sophora, an arborescent Fabaceae native to Asia and planted mainly in parks and gardens in France, testifies to the preference of Megachile sculpturalis for this species, at least in the studied area. Further investigations are needed to know to what extent M. sculpturalis prefers collecting pollen on Sophora japonica.L’étude du contenu pollinique de deux échantillons prélevés, soit sur un spécimen de Megachile sculpturalis Smith, 1853, soit dans la loge d’un “ hôtel à insectes” fréquenté par cet Hyménoptère, livre des indications préliminaires sur le comportement de butinage et sur le régime alimentaire de cette abeille invasive dont la première observation en France date de 2008. La domination des assemblages polliniques par le pollen de Sophora, une Fabaceae arborescente originaire d’Asie et plantée essentiellement dans les parcs et jardins en France, témoigne de la préférence de Megachile sculpturalis pour cette essence, au moins dans la localité étudiée. L’étude se basant seulement sur deux échantillons, de nouvelles analyses sont nécessaires pour approfondir les connaissances sur ses besoins alimentaires et pour statuer sur une éventuelle préférence ou spécialisation sur Sophora japonica pour la collecte du pollen.Andrieu-Ponel Valérie, Ponel Philippe, Le féon Violette, Geslin Benoît, Duvallet Gérard.

profiling and role of bioactive molecules from puntius sophore freshwater brackish fish skin mucus with its potent antibacterial antiadhesion and antibiofilm activities
Biomolecules, 2020Co-Authors: Mitesh Patel, Mohammad Saquib Ashraf, Arif Jamal Siddiqui, Syed Amir Ashraf, Manojkumar Sachidanandan, Mejdi Snoussi, Mohd Adnan, Sibte HadiAbstract:Epidermal fish mucus comprises of diverse bioactive metabolites which plays an immense role in defense mechanisms and other important cellular activities. Primarily, this study aims to screen the unexplored mucus extract of Puntius sophore (P. sophore) for its antagonistic potential against common pathogens, which are commonly implicated in foodborne and healthcare associated infections, with effects on their adhesion and biofilm formation. Profiling of the skin mucus was carried out by High Resolution-Liquid Chromatography Mass Spectrometry (HR-LCMS), followed by antibacterial activity and assessment of antibiofilm potency and efficacy on the development, formation, and texture of biofilms. Furthermore, bacterial cell damage, viability within the biofilm, checkerboard test, and cytotoxicity were also evaluated. As a result, P. sophore mucus extract was found to be effective against all tested strains. It also impedes the architecture of biofilm matrix by affecting the viability and integrity of bacterial cells within biofilms and reducing the total exopolysaccharide content. A synergy was observed between P. sophore mucus extract and gentamicin for Escherichia coli (E. coli), Pseudomonas aeruginosa (P. aeruginosa), and Bacillus subtilis (B. subtilis), whereas, an additive effect for Staphylococcus aureus (S. aureus). Thus, our findings represent the potent bioactivities of P. sophore mucus extract for the first time, which could be explored further as an alternative to antibiotics or chemically synthesized antibiofilm agents.

mesorhizobium calcicola sp nov mesorhizobium waitakense sp nov mesorhizobium Sophorae sp nov mesorhizobium newzealandense sp nov and mesorhizobium kowhaii sp nov isolated from Sophora root nodules
International Journal of Systematic and Evolutionary Microbiology, 2016Co-Authors: Sofie E De Meyer, P. B. Heenan, M. Andrews, Anne WillemsAbstract:In total, 31 strains of Gram-stain-negative, rod-shaped bacteria were isolated from Sophora root nodules and authenticated as rhizobia on this host. Based on 16S rRNA gene phylogeny, they were shown to belong to the genus Mesorhizobium, with the representative strains ICMP 19560T, ICMP 19523T, ICMP 19535T, ICMP 19545T and ICMP 19512T being related most closely to Mesorhizobium sangaii SCAU7T (99.9–99.6 % similarity), Mesorhizobium cantuariense ICMP 19515T (99.7–99.6 %) and Mesorhizobium ciceri UMP-CA7T (99.7–99.5 %). Additionally, the novel strains formed distinct groups based on housekeeping gene sequence analysis and were closely related to Mesorhizobium waimense ICMP 19557T (93.5–94.9, 92.5–95.6 and 94.2–96.0 %), M. cantuariense ICMP 19515T (93.1–97.7, 93.5–95.4 and 94.8–96.8 %) and M. ciceri UMP-CA7T (93.2–97.2, 94.6–96.8 and 95.5–97.3 %) for glnII, recA and rpoB, respectively. Chemotaxonomic data supported the assignment of the strains to the genus Mesorhizobium, and DNA–DNA hybridizations, matrix-assisted laser desorption/ionization time-of-flight MS analysis, enterobacterial repetitive intergenic consensus PCR, physiological and biochemical tests allowed the genotypic and phenotypic differentiation from their nearest neighbouring species. Therefore, these strains represent five novel species for which the names Mesorhizobium calcicola sp. nov. (type strain ICMP 19560T = LMG 28224T = HAMBI 3609T), Mesorhizobium waitakense sp. nov. (type strain ICMP 19523T = LMG 28227T = HAMBI 3605T), Mesorhizobium Sophorae sp. nov. (type strain ICMP 19535T = LMG 28223T = HAMBI 3606T), Mesorhizobium newzealandense sp. nov. (type strain ICMP 19545T = LMG 28226T = HAMBI 3607T) and Mesorhizobium kowhaii sp. nov. (type strain ICMP 19512T = LMG 28222T = HAMBI 3603T) are proposed.
