Out of the selected various solvent extracts‚ in bacterial study‚ acetone extract showed a maximum zone of inhibition against Staphylococcus aureus. In fungal study‚ ethyl acetate extract showed maximum zone of inhibition

Each sample was independently examined towards antibacterial activity using two types of micro-organisms (Escherichia coli AATCC 2666 gram negative (ve) and Staphylococcus aureus AATCC 6538 gram positive (+ve)). The result was taken after 4 hours‚ 8 hours and after 24 hours. 2.4. Physico mechanical measurments: 2.4.1.

Unfortunately‚ they are indiscriminate and also kill the good bacterium that are mostly found in the large intestinal tract. This leaves a person open to reinfection‚ or other more

Bacterial Smears Are Fixed before Staining to? Answer It is important to heat fix the bacterial smear before staining so as to‚ kill the bacteria‚ firmly adhere the smear on to the microscopic slide to prevent washing off during staining‚ and to allow the sample to readily take up the stain. Reference: www2.hendrix.edu What is the purpose of heat- fixing the smear? It helps the cells adhere to the slide so that they can be stained. The purpose of heat fixing is to kill the organisms without

Survey of Nasal Carriage of Staphylococcus aureus in Microbiology 1 Students at RMIT Aim: To determine the carriage rate of Staphylococcus aureus in the nares of students taking second year microbiology courses at RMIT. Introduction: Carriage of S.aureus is important in hospital patients‚ preoperative patients‚ hospital staff‚ food handlers etc. because it carriage of S.aureus appears to play a key role in the epidemiology and pathogenesis of infection. S.aureus can cause localized and invasive

Chapter 1 INTRODUCTION 1. Background of the study With the alarming increase of health threatening diseases caused by microbial organisms in the world‚ Philippines is one of the countries that has a rapid spread of different systematic bacterial diseases. Number of victims near Manila has risen to 1‚447 as of February 2008 (Entis‚ 2008). Some of these contaminations are caused by Salmonella spp.‚ a member of the family Enterobacteriacea‚ a fairly common cause of food poisoning (Burton

physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases - enzymes which break down agarose into oligosaccharides. This physiological class branches through genii‚ regardless of Gram Stain status or morphology. Through a review of scientific literature we can find identification methods‚ optimum conditions and the general function and location of agarolytic bacteria‚ as well as methods to culture them in vitro for study and experimentation
