Methanolic extract of Trianthema decandra was investigated for its antibacterial activity against staphylococcus aureus (NCIM 2079), Escherichia coli (NCIM 2065), Bacillus subtilis (NCIM 2063), Pseudomonas aeruginosa (NICIM 2036) and Proteus vulgaris (NICIM 2027) at 100 μg/disc using disc diffusion method. The extract showed significant antibacterial activity and were comparable to Chlorampheni...

A purple discolouration of urine and the urine bag was observed in a 73-year-old female patient suffering from alpha 1-antitrypsin deficiency and acute on chronic renal failure caused by ACE inhibitors and diuretics. The patient was fairly immobile after a trauma and constipated from morphine analgesics. A urinary tract infection was diagnosed, and a urine culture grew Escherichia coli and Prot...

Antimicrobial activities of methanolic and petroleum ether extracts of Croccus sativus L. (saffron) stigmas, were tested against various bacterial strains (Proteus vulgaris, Klebsiella pneumonia, Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli) and fungi (Candida albicans, Aspergillus niger and Aspergillus fumigatus) by agar well diffusion method. Minimal inhibitory concentra...

Plants with an established history of medicinal uses were tested against various microorganisms in this study. We compared the antibacterial activity of methanol, ethanol, and water extracts of three plant species, including Origanum syriacum, Thymus vulgaris, and Carica papaya, which commonly grow in open habitats or mountainous areas with well-drained soil. The methanol and ethanol extracts o...

The antimicrobial activity of alcoholic, butanolic and chloroform extracts of leaves and roots of the plant Acanthus ilicifolius ware studied. Ampicillin and clotrimazole were used as standard antibacterial and antifungal agents respectively. The result of the study revealed that the alcoholic extract and chloroform extract of leaves exhibited strong inhibitory action against Bacillus subtilis,...

New carbapenern antibiotics, C-19393 S2 and H2, have been found to be potent and broadspectrum inhibitors of /3-lactamases. Among 11 types of /3-lactamases tested, those from Escherichia coli (plasmid-bearing), Klebsiella pneumoniae, Proteus vulgaris, Serratia marcescens and Bacteroides fragilis were especially sensitive. They also inhibited cephalosporinases insensitive to clavulanic acid. The...

Plant extracts are very cost effective and eco-friendly and thus can be used as an economic and efficient alternative for the large-scale synthesis of nanoparticles. We report on the use of ginger extract for the biosynthesis of silver nanoparticles. Bioactive silver nanoparticle synthesis was byreacting the ginger extract with aqueous silver nitrate solution at room temperature (27±2 C) and at...
