The present study was designed to evaluate the antimicrobial activity of leaf of Pithecellobium dulce against twenty pathogenic microorganisms. Leaf extracts of P. dulce were prepared in distilled water and organic solvents, viz., benzene, chloroform, acetone and methanol in increasing and decreasing order of solvent polarity. Agar well diffusion technique was used to assess the antimicrobial a...

Inoculum suspensions were prepared from 7 to 14 day cultures on potato carrot agar, by slightly scraping the surface of mature colonies with a sterile cotton swab wetted with sterile saline including Tween 40 (0.05%). The super-natants were adjusted spectrophotometrically at a wavelength of 530 nm to an optical density (OD) that ranged from 0.25 to 0.3 (2Â10 4 –7Â10 4 cfu/mL). 3 Microdilution p...

PURPOSE Hypersensitivity to fungi is associated with rhinoconjunctivitis and asthma. For some fungi, such as Alternaria alternata (A. alternata), the symptoms of asthma are persistent, increasing disease severity and the risk of fatal outcomes. There are a large number of species of fungi but knowledge of them remains limited. This, together with the difficulties in obtaining adequate standardi...

Tomato plants are subject to attacks by different types of fungi most which destructive and cause plant death. Extensive researches were carried out attempting find safe easily degradable bio-fungicides with minimum adverse effects. Therefore, naturally originated indigenous products generally considered excellent alternative phytopathogen controlling agents. In recent study we evaluated the an...

Plants historically have served as models in drug development. The production of medicines and the pharmacological treatment of diseases began with the use of herbs. The antifungal activity of five different plants namely, Aegle marmelos, Carica papaya, Mentha arvensis, Nicotiana plumbaginifolia and Tamarindus indica were tested against plant pathogenic fungi Alternaria alternata. The plant ext...
