The purpose of our present study is to test antimicrobial and antifungal activity of polyherbal formulations. The testing of the antimicrobial activity on polyhernal formulation was done against gram positive (Staphylococcus aureus, Bacillus subtilis) and gram negative (Salmonella typhi, Escherichia coli,) bacteria. The testing of antifungal activity was done against Aspergillus niger and Candida albicans with different combinations of polyherbal formulation. The microorganism to be tested was grown in relevant nutritional media. The solvent used for the extraction of Moringa oleifera, Viola odorata, Allium sativum was methanol. These methanolic extracts of chosen plants were further used in specific proportions for the preparation of polyherbal formulation (PF-1, PF-2, and PF-3). The resultant compositions were further used to check the efficacy against selected experimental microorganisms. PF-3 showed the significant high zone of inhibition against all the experimental microorganisms as compared to the other two combinations PF-1 and PF-2. Thus, the result has revealed that the antimicrobial activity is due to the synergistic effect of secondary metabolites present in these selected plants.

Ayurvedic medicines are being used increasingly to fight or prevent common diseases. Udhara vayuhara churna is a polyherbal formulation containing Piper longum (Piperceae) Zingiber officinalis (Zingiberaceae), Elettaria cardamom (Zingiberaceae), Plumbago zeylanica (Plumbaginaceae), Carum carvi (Umbelliferae), Acorus calamus (Araceae) and Embilica officinalis (Euphorbiaceae). Methanolic and aqueous extracts of Udhara vayuhara churna were screened for their antimicrobial activity against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Aspergillus niger and Candida albicans. The results of antimicrobial activity of aqueous and methanolic extracts of the Udhara vayuhara churna indicated that methanolic extract inhibited the growth of one or more test pathogens than aqueous extract. Udhara vayuhara churna formulation extracts showed a broad spectrum of antimicrobial activity. Phytochemical investigation revealed the presence of tannins, saponins, alkaloids, glycosides, flavonoids and essential oils. This may be due to the multifunctional effect of all the seven plant ingredients of Udhara Vayuhara churn.

The present study focused on the prospect of fabricating a polymeric naturally extracted Moringa oleifera oil bionanocomposite film enriched with silver nanoparticles for antimicrobial activity. In this study, a standard concentration of Moringa oleifera oil (5-10 wt%) was used to fabricate a polymeric bionanocomposite film using polyvinyl chloride (PVC) enriched with silver nanoparticles. The active constituents of the extracted Moringa oleifera oil were verified using gas chromatography-mass spectrometry. Spectroscopic and microscopic techniques, including scanning electron microscopy, X-ray diffraction, and energy-dispersive X-ray analysis, were employed to characterize and study the surface morphology of the fabricated bionanocomposite film. The antimicrobial activity of the fabricated bionanocomposite film was investigated using different strains of bacteria and fungus. The results revealed well-oriented and excellently dispersed silver nanoparticles in the PVC-Moringa oleifera oil matrix. The bionanocomposite was able to inhibit the growth of Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Salmonella typhi, Pseudomonas aeruginosa, Shigella flexneri, and Candida albicans. The combination of nanoparticles with polymers is opening new routes for engineering fixable composites, which showed antimicrobial properties.

In the present study, mushrooms, Pleurotus ostreatus and Pleurotus florida, were cultivated on different agricultural wastes namely coffee straw (CS), pea straw (PS), Sorghum Grain Residue (SGR), and Wheat Grain (WG) for the evaluation of antibacterial activity. Antimicrobial activity evaluation was carried out against human pathogenic microorganisms, namely, Escherichia coli, Bacillus subtilis, Streptococcus faecalis, Pseudomonas aeruginosa, and Salmonella typhi by using the disc diffusion method. Methanolic extracts of P. ostreatus cultivated on a Sorghum grain residue substrate were recorded for the highest antibacterial activity against E. coli (19.8 mm) and P. aeruginosa (16.4 mm), and methanolic extracts of P. florida cultivated on a wheat grain substrate were recorded for the highest antibacterial activity against E. coli (18.6 mm) and S. faecalis (14.8 mm). Therefore, results suggested that P. ostreatus and P. florida cultivated on the coffee straw and Sorghum grain substrate were found with the highest antimicrobial activity in comparison to other substrates. The results supported that the methanolic extracts of P. ostreatus and P. florida might indeed be potential sources of antibacterial agents.

In this study, antimicrobial activities of two different samples ofAllium sativumL. from Turkey (TR) (Taşköprü, Kastamonu, Turkey) and China (CN) were determined. A broad spectrum of Gram-negative and Gram-positive bacteria (17 bacteria) including species ofBacillus,Enterobacter,Enterococcus,Escherichia,Klebsiella,Listeria,Pseudomonas,Salmonella, andStaphylococcuswere used for testing antibacterial activity. In addition, antifungal activity againstCandida albicanswas also investigated. Antimicrobial activity was tested by using 3 different processes (chopping, freezing, and slicing by the disk diffusion method). The results showed that TR garlic presented more antimicrobial activity than CN garlic. Mechanism of activity of CN garlic could be proposed to be different from that of TR garlic.

In the genesis of using plants for treatment of diseases, Garlic and lemon grass were some of the earliest plants that have proven effective. In this study the antimicrobial effect of Cymbopogon citratus (lemon grass) and Allium sativum (garlic) extracts on clinical isolate of Salmonella typhi  was examined. Water, ethanol and methanol were used as extraction solvent. Antimicrobial effects of conventional antibiotics was assayed using disc diffusion method while antimicrobial activity of lemon grass and garlic extracts were carried out using agar well diffusion method and the zones of inhibition was measured in millimeter (mm). Comparatively, the highest percentage yield of extract was observed in water extract of garlic (21.83%) and lemon grass (6.67%). Ciprofloxacin and Perfloxacin have the highest zones of inhibition of 19.73±0.24mm and 14.47±0.31mm respectively against the clinical isolates of Salmonella typhi . Two out of the twelve clinical isolate of Salmonella typhi  used were multi drug resistant. Lemon grass extracts did not show any antimicrobial effects on the clinical isolates of Salmonella typhi  while garlic extracts showed antimicrobial effect at the concentration of 800 mg/ml, water extract of garlic has the highest zone of inhibition (14.00 mm) against the tested isolates. Therefore garlic extract could be used for the formulation of drug and treatment of Salmonella typhi   infection.

The three copper complexes having a-ketoglutaric acid (H2A) and 1- (o-tolyl) biguanide (TB) ligands have been synthesized and characterized. The proposed formulas for these complexes are: [Cu(TB)(HA)]Cl (C1), [Cu(TB)(HA)CH3COO]�H2O (C2) and [Cu(TB)(HA)](NO3) (C3) where HA represents deprotonated H2A. The complexes obtained were tested for antibacterial activity against Staphylococcus aureus ATCC 25923 and Pseudomonas aeruginosa ATCC 27853, antifungal activity on Candida albicans ATCC 10231 and antitumor activity on HeLa tumor cells. Due to the antitumor, antifungal, antimicrobial activity and inhibition of inert substrate adhesion, complexes synthesized could be used for potential therapeutic applications.

Background: Although a great number of the targets of antimicrobial therapy have been achieved, it remains among the first fields of pharmaceutical research, mainly because of the development of resistant strains. Docking analysis may be an important tool in the research for the development of more effective agents against specific drug targets or multi-target agents 1-3. Methods: In the present study, based on docking analysis, ten tetrahydrothiazolo[2,3-a]isoindole derivatives were chosen for the evaluation of the antimicrobial activity. Results: All compounds showed antibacterial activity against eight Gram-positive and Gram-negative bacterial species being, in some cases, more potent than ampicillin and streptomycin against all species. The most sensitive bacteria appeared to be S. aureus and En. Cloacae, while M. flavus, E. coli and P. aeruginosa were the most resistant ones. The compounds were also tested for their antifungal activity against eight fungal species. All compounds exhibited good antifungal activity better than reference drugs bifonazole (1.4 – 41 folds) and ketoconazole (1.1 – 406 folds) against all fungal species. In order to elucidate the mechanism of action, docking studies on different antimicrobial targets were performed. Conclusion: According to docking analysis, the antifungal activity can be explained by the inhibition of the CYP51 enzyme for most compounds with a better correlation of the results obtained for the P.v.c. strain (linear regression between estimated binding Energy and log(1/MIC) with R 2 =0.867 and p=0.000091 or R 2 = 0.924, p= 0.000036, when compound 3 is excluded.
