INTRODUCTION Cassia fistula Linn. (Leguminosae) is a very common plant and is widely known for its medicinal properties. In the Indian literature‚ this plant has been described to be useful against skin diseases‚ liver troubles‚ tuberculous glands and its use in the treatment of rheumatism‚ hematemesis‚ pruritus‚ leucoderma‚ and diabetes.[1‚2] Besides‚ it has been found to exhibit anti-inflammatory and hypoglycemic activity and widely used as a mild laxative suitable for children and pregnant women

Abstract: This lab works to develop the understanding of bacterial transformation through the integration of a plasmid into E-coli bacteria. Understanding of plasmids‚ GFP‚ expression of genes and bacterial candidates is used to formulate a lab which demonstrates a variety of factors associated with transformation efficiency. It was deduced that there are certain requirements present in the pGLO plasmid for full gene expression and that an increase in transformation solution positively impacts

Shigellae are Gram-negative‚ nonmotile‚ non-spore forming‚ rod-shaped bacteria‚ very closely related to Escherichia Shigella were discovered over 100 years ago by the Japanese microbiologist‚ Shiga‚ for whom the genus is named. There are four species of Shigella: S. boydii‚ S. dysenteriae‚ S. flexneri‚ and S. sonnei. Shigella sonnei‚ also known as Group D Shigella

Escherichia coli 0157:H7 OR (E. coli) is a food born pathogen that can cause serious illness or if left untreated can cause death. One of the obvious symptoms of E. coli is bloody diarrhea although not all forms of E coli have the same symptoms. The main toxins all strains of E. coli produce are called shiga toxins‚ the toxins alone are not able to make E. coli pathogenic it needs the presence of other virulence markers. The symptoms can easily be confused with other illnesses or diseases. It starts

maximum growth rate and Monod constant must be found. Here we show how the maximum growth rate and Monod constants can be obtained for Escherichia coli using M9 media in a bioreactor at 37 °C and 500 RPM. The maximum growth rate is also obtained at other settings to show how other factors can affect bacterial growth. The maximum growth rate and Monod constants for E. coli with these settings were found to be ~ 0.0600 hr-1 and ~ 4.2 g/L respectively. With the Monod constant and maximum

ABSTRACT The aim of this study was to investigate the activity of (28%) ethanolic extract propolis (EEP) of [Bazian‚ Pshdar‚ Sharbazher‚ Khormal‚ Kanakawa and Sulaimani (city center)] against (Staphylococcus aureus‚ Staphylococcus epidermidis‚ Escherichia coli‚ Pseudomonas aerugenosa‚ Klebsiella pneumoniae‚ Proteus mirabilis and yeast Candida albicans). Two methods were employed for propolis activity evaluation; firstly by agar well diffusion method using 40µl of propolis extracts and ethanol 70%
