Antiparasitic and antimicrobial activity of Ipomoea palmata against Toxoplasma gondii and Staphylococcus aureus : correlation with major phenolics identified by HPLC

Artificial Cells Nanomedicine and Biotechnology, Год журнала: 2025, Номер 53(1), С. 194 - 206

Опубликована: Апрель 26, 2025

Toxoplasma gondii, a protozoan parasite found in water sources, causes toxoplasmosis, with no current protocols for inactivating its oocysts water. Staphylococcus aureus, significant bacterial pathogen, is known causing various illnesses, including skin infections and biofilm-related diseases. This study investigated the antibacterial antiparasitic properties of Ipomoea palmata leaf extract, rich phenolics, against T. gondii tachyzoites S. aureus. I. extract significantly reduced count peritoneal fluids liver smears infected mice alleviation toxoplasmosis-induced hepatitis. SEM showed surface irregularities from treated groups. The demonstrated action aureus minimum inhibitory concentration 128 to 512 µg/mL, biofilm formation 69.23% 15.38% tested isolates, downregulated genes (cna, fnbA, ica) 53.85% isolates. Treatment improved architecture, inflammation, eliminated blood vessel congestion. main phenolic acids identified by HPLC/UV analysis were chlorogenic acid, gallic ellagic methyl gallate, while predominant flavonoids apigenin, quercetin, naringenin. These findings highlight potential as natural antimicrobial agent, warranting further research isolate evaluate active compounds.

Adansonia digitata L . is a royal tree that highly valued in Africa for its medicinal and nutritional properties. The objective of this study was to use fruit shell extract develop new, powerful mono bimetallic nanoparticles (NPs) biochar (BC) using an eco-friendly approach. Silver (Ag), iron oxide (FeO), the Ag-FeO NPs, as well were fabricated by A. through reduction process biomass pyrolysis, respectively, their activity against tomato pathogenic fungi Alternaria sp., Sclerotinia sclerotiorum , Fusarium equiseti venenatum detected agar dilution method. Ag, FeO, Ag-FeONPs, BC characterized range analytical techniques such ultraviolet–visible (UV–Vis) spectroscopy, scanning electron microscopy (SEM), transmission (TEM), Fourier Transform-Infra Red (FT-IR), dynamic light scatter (DLS), zeta potential analysis. FeO NPs have demonstrated remarkable level effectiveness combating fungal strains. UV–Vis spectra ofAg, show broad exhibits peaks at 338, 352, 418, 480 nm, respectively. monometallic, indicated presence various forms mostly Spherical-shaped. Their size varied from 102.3 183.5 nm corresponding FTIR suggested specific organic functional groups plant played significant role bio-reduction process. Ag exhibited excellent antifungal S. sclerotiorum, F. current could be achievement field agents since has new approaches treating infections.

Effective antibacterial agents in modern wound dressings: a review

Biofouling, Год журнала: 2024, Номер 40(5-6), С. 305 - 332

Опубликована: Июнь 5, 2024

Wound infections are a significant concern in healthcare, leading to long healing times. Traditional approaches for managing wound rely heavily on systemic antibiotics, which associated with the emergence of antibiotic-resistant bacteria. Therefore, development alternative antibacterial materials care has gained considerable attention. In today's world, new generations dressing commonly used heal wounds. These dressings keep and area around it moist improve healing. However, this environment can also foster an that is favorable growth Excessive antibiotic use poses threat human health causes bacterial resistance, so new-generation must be designed developed reduce risk infection. using antimicrobial compounds minimize colonization, making them best way avoid open We aim provide readers comprehensive understanding latest advancements management.
