“…Indeed, the plant extract stopped the growth of C. albicans . Additionally, Gholampour-Azizi et al [ 77 ], studied the in vitro antifungal activity of Cucumis melo and he demonstrated that it exhibited specific antifungal activity against C. albicans . Likewise, it has been demonstrated that aqueous and ethanolic extracts from T. polium showed an antifungal effect against C. albicans [ 78 ].…”

The chemical profile of Teucrium polium L. (T. polium) methanolic extract was tested using liquid chromatography coupled with high resolution mass spectrometry (HR-LCMS). Disc diffusion and microdilution assays were used for the antimicrobial activities. Coxsackievirus B-3 (CVB3) and Herpes simplex virus type 2 (HSV-2) were used for the antiviral activities. Chromobacterium violaceum (ATCC 12472 and CV026) and Pseudomonas aeruginosa PAO1 were used as starter strains for the anti-quorum sensing tests. Isoprenoids are the main class of compounds identified, and 13R-hydroxy-9E,11Z-octadecadienoic acid, valtratum, rhoifolin, sericetin diacetate, and dihydrosamidin were the dominant phytoconstituents. The highest mean diameter of growth inhibition zone was recorded for Acinetobacter baumannii (19.33 ± 1.15 mm). The minimal inhibitory concentrations were ranging from 6.25 to 25 mg/mL for bacterial strains, and from 6.25 to 25 mg/mL for Candida species. The 50% cytotoxic concentration on VERO (African Green Monkey Kidney) cell lines was estimated at 209 µg/mL. No antiviral activity was recorded. Additionally, T. polium extract was able to inhibit P. aeruginosa PAO1 motility in a concentration-dependent manner. However, the tested extract was able to inhibit 23.66% of the swarming and 35.25% of swimming capacities of PAO1 at 100 µg/mL. These results highlighted the role of germander as a potent antimicrobial agent that can interfere with the virulence factors controlled by the quorum-sensing systems.

“…Candida species are opportunistic pathogens and accounted for a substantial morbidity rate and can result in hospitalization and expensive therapies [18] (Gholampour-Azizi et al, 2015). For immune-compromised patients, Candida albicans is an important opportunistic fungal pathogen and the major cause of oropharyngeal candidiasis [19] (Steenkamp et al, 2007).…”

In the present study, fifteen species of the dominant marine algae were collected during summer 2013 from four selected sites on Red sea coast, Jeddah, Saudi Arabia. The collected species belonged to Chlorophyta, Phaeophyta and Rhodophyta. Crude algal extracts were prepared by successive extractions using different solvents (acetone, ethanol, diethyl ether, ethyl acetate, methanol and petroleum ether). The crude algal extracts were examined for their antifungal efficacy against Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Candida albicans and Candida tropicalis using agar well diffusion method. The algal extracts evoked different patterns of antifungal activities. Results reveal that acetone was the best solvent suited for extraction of bioactive compounds from tested seaweeds with inhibition activity (19.3%) followed by ethyl acetate (17.1%), ethanol (16.4%), petroleum ether (15.9%), diethyl ether (15.85%), and finally methanol (15.4%). Chlorophyta exhibited the highest antimycotic effect followed by Rhodophyta and Phaeophyta. In Chlorophyta, the extracts of Ulva intestinalis were the most potent followed by U. lactuca, C. racemosa, U. linza and U. reticulate. Acanthophora spicifera showed the highest activity in Rhodophyta, followed by J. rubens, D. simplex, L. obtusa, G. gracilis, G. vermicuphylla and G. multipartita. Whereas, T. triquetra was the most effective species in Phaeophyta followed by P. pavonica and D. dichotoma. The minimal inhibitory concentrations (MICs) of the most potent algal extracts were in the range of 0.5 to 4 mg/ml. The results confirmed the antimycotic potentiality of seaweed extracts.

Introduction:Pseudomonas aeruginosa, a Gram-negative bacterium, is the cause of infections in immunocompromised individuals, resulting in various conditions, including pneumonia, and urinary tract, skin, and bloodstream infections. This pathogen produces tissue-destructing toxins, leading to significant morbidity and mortality in affected patients. Conventional antibiotics, including rifampicin and colistin, are often ineffective in treating P. aeruginosa infections due to the emergence of bacterial resistance within affected communities. Alternatively, algae have been explored as a promising source for controlling pathogenic bacteria. In this study, we investigated the antibacterial effects of ethanol and aqueous extracts of Spirulina platensis against P. aeruginosa. Methods: Ethanol and aqueous extracts of S. platensis were prepared at concentrations of 0.125, 0.25, 0.5, and 1 mg/mL. The antibacterial effect of Spirulina blue-green algae against P. aeruginosa was conducted using a disc diffusion test in an LB medium with 7-mm wells. We measured the inhibition zone and statistically analyzed the data by comparing the means using the Duncan multiple range test. Results: The ethanol extract of S. platensis significantly inhibited the growth of P. aeruginosa. Furthermore, applying the ethanol extract of S. platensis at a concentration of 1 mg/mL resulted in the largest inhibition zone (20 mm) compared to the control. In contrast, the S. platensis aqueous extract did not significantly inhibit P. aeruginosa growth. Conclusions: The ethanol extracts of S. platensis algae exhibited a significant antibacterial effect against P. aeruginosa. This alga represents a promising source of antibacterial metabolites, which could be a suitable alternative to common antibiotics. Further investigations are necessary to identify and purify the specific antibacterial substance in S. platensis.25. Breijyeh Z, Jubeh B, Karaman R.
