Aedes aegypti larvae have developed tolerance to many insecticides used for mosquito control. Moringa oleifera seeds contain a water-soluble lectin (WSMoL) and this paper reports the effect of M. seed extracts (MoE(1-15)) WSMoL on development survival A. larvae. peptide from in-gel trypsin digestion is also described. MoE(1-15) showed hemagglutinating activity had similarity with flocculating proteins seeds. MoE(1) MoE(3) delayed larval which stopped in third instar (L3) MoE(6) MoE(15)....
Natural insecticides against the vector mosquito Aedes aegypti have been object of research due to their high level eco-safety. The water-soluble Moringa oleifera lectin (WSMoL) is a larvicidal agent A. aegypti. This work reports effects WSMoL on oviposition and egg hatching aegypti.WSMoL crude preparations (seed extract 0-60 protein fraction), at 0.1 mg/mL concentration, did not affect oviposition, while gravid females laid eggs preferentially (73%) in vessels containing isolated (0.1...
The Alpinia purpurata inflorescence contains a lectin (ApuL), which has immunomodulatory activities on human cells. In the present work, it was evaluated antibacterial and antifungal effects of ApuL against pathogens. showed bacteriostatic activity non-resistant (UFPEDA-02) an oxacillin-resistant isolate (UFPEDA-672) Staphylococcus aureus with minimal inhibitory concentrations (MIC50) 50 400 μg/mL, respectively. addition, bactericidal effect (minimal concentration: 200 μg/mL). For Candida...
The lesser mealworm, Alphitobius diaperinus, is a widespread pest in poultry farming, causing economic losses and facilitating the spread of pathogens. Current control methods rely heavily on synthetic insecticides, which raise environmental concerns contribute to resistance. This study investigated insecticidal potential Moringa oleifera seed preparations, including an aqueous extract (AE), protein-enriched fraction (PF), isolated lectin (WSMoL), against A. diaperinus. Contact assays...
Spondias tuberosa is a plant that produces fruit crop with high economic relevance at Brazilian Caatinga. Its roots and leaves are used in folk medicine.Chemical composition of hexane extract from S. was evaluated by thin-layer chromatography (TLC), high-performance liquid (HPLC) 1H nuclear magnetic resonance (NMR). Antioxidant potential investigated DPPH ABTS assays. Antifungal action on Candida species determining the minimal inhibitory concentration (MIC50) putative mechanisms were...
Moringa oleifera seed cake, which is the coproduct of oil extraction, may be a source lectin. This study reports purification lectin from M. cake (WSMoLC) and determination its effect on larvae, eggs oviposition Aedes aegypti. WSMoLC was isolated (purification fold: 3573) by treatment water extract with ammonium sulphate (60%) chromatography lectin-rich fraction chitin column. In gel trypsin, digestion followed mass spectrometry revealed similarity peptides other proteins. exerted...
The water-soluble Moringa oleifera lectin (WSMoL) exhibits larvicidal, ovicidal, and oviposition-stimulant effects on Aedes aegypti. Here, we evaluated the influence of gamma irradiation activity WSMoL against A. Irradiation with 10 mGy Gy did not result in loss protein molecules; however, irradiated samples presented a distinct profile gel filtration chromatography. Bis-ANS probe fluorescence was similar when incubated non-irradiated mGy-irradiated samples, but less intense observed...
Abstract Our objectives were to identify genes of the multi-drug efflux system and evaluate antimicrobial activities polypyrrole nanoparticles (PPy-NPs) aqueous extract Moringa oleifera against Staphylococcus spp. isolated from dairy farms in Northeast Brazil. Initially, 162 isolates subjected vitro sensitivity tests. Of these, 35 presented resistance phenotypes. These then referred for detection norA, norB, norC, msrA, mgrA, tet-38, lmrS genes, all which feature systems. In carrying minimum...
This work aimed to purify, characterize, and evaluate the immunomodulatory activity of a lectin from Aesculus hippocastanum seeds (AhSL). The was isolated saline extract through chromatography on DEAE-Sephadex column. Protein homogeneity subunit composition were evaluated with polyacrylamide gel electrophoresis (PAGE) under native denaturing (SDS-PAGE) conditions, respectively. AhSL for trypsin inhibitor activity, carbohydrate-binding specificity, effects cations (Ca2+, Mn2+, Mg2+),...
The mosquito Aedes aegypti L. is a vector transmitting diseases such as dengue, chikungunya and Zika virus fever. water-soluble lectin from Moringa oleifera Lam. seeds (WSMoL) larvicidal, ovicidal can stimulate oviposition in A. aegypti. This study aimed to investigate whether WSMoL could bind membrane proteins legs. Initially, the legs were extracted using sodium deoxycholate, digitonin, dodecyl sulfate (SDS) or Triton X-100. protein concentration was found be higher extract obtained X-100,...
