The following show expected colony appearances and morphologies (shapes) of Escherichia coli and Staphylococcus aureus. Note characteristics such as edges‚ color‚ and whether the colonies are rough or smooth in texture. For colony appearances of E. coli and S. aureus‚ scientists often describe what they look like on agar. This is not the microscopic view (for example‚ as with a slide) but a “naked eye” view of how the bacterial colonies look while growing on a medium. (This is one type of culture

Urinary tract infections refer to the presence of pathogenic microorganisms within the urinary tract and its classification is usually done on the basis of infection sites:-bladder [cystitis]‚ kidney [pyelonephritis]‚ or urine [bacteriuria] and also can be asymptomatic or symptomatic (Quigley R 2009‚ Schlager TA2001). They are among the most commonly acquired bacterial infections and they account for an estimated 25-40% of the nosocomial infections (Bagshaw SM‚ Laupland KB 2006). Urinary tract infection

The GFP‚ isolated from the jellyfish Aequorea victorea‚ glows in the presence of U.V light (Sanders and Jackson‚ 2009). Materials and Methods A 250µl of a calcium chloride transformation solution ‘TS’ was added to each of two different tubes of Escherichia coli HB101 kept in an ice bucket. The tubes were marked as ‘pGLO’ and ‘control’ respectively. A 10µl of pGLO DNA sample was added to the tube marked ‘pGLO’. A 10µl of sterile water was added to the ‘control’ tube; both tubes were placed on ice for

Is there a significant difference in the antibacterial properties of the plant extract on Pseudomonas and Escherichia Coli as shown by the zone of inhibition? 3. Does the stickcane shoots extract exhibit antibacterial property? Significance of the Study The result of this study can be beneficial to the community. It can motivate the mass production of

Introduction: Escherichia coli is a bacterium that can affect our health or even kill. Like most bacteria‚ E. coli is able to change and progress into different forms based on genetic changes that they can go through. One example of this genetic change is shown in the E. coli becoming immune to ampicillin is blood infections. Because ampicillin has been used so frequently to fight the symptoms of an E. coli infection‚ the bacteria has been able to change itself genetically by producing more of

Chapter 1 The Problem Introduction Today’s technological innovation and medical advances gave birth to formulation of synthetic drugs used to treat respiratory infections‚ urinary tract infections‚ diarrhea‚ arthritis and other diseases. These pharmaceuticals are costly and to a point‚ inaccessible to many Filipinos. These may also pose adverse effects like nausea‚ dyspnea‚ and diarrhea. Researchers are challenged to produce natural medicines‚ which could be lower in cost and more synergistic
