In this experiment six antibiotics will be tested to determine which is the most effective on gram-negative bacterium Escherichia Coli and gram-positive bacterium Bacillus Cereus. In previous class experiments‚ gram-staining was conducted to determine the qualities of gram-positive

growth of Escherichia coli Abstract Bacteria growth is known to be either augmented or impeded by a number of various factors; in this experiment‚ our group tested how E. coli is affected by penicillin as well as how different temperatures can affect bacteria growth. We know that antibiotics are generally specialized against certain types of bacteria—more specifically‚ some are most effective against Gram-negative‚ some against Gram-positive‚ and some are more broad spectrum. Given that E. coli is known

Foodborne Illness – Staphylococcus • What is the infectious agent (pathogen) that causes this infectious disease? Staphylococcus is an unmodifiable bacterium that causes Botulism. Which mean that individuals have no control over catching or not catching this disease. Since botulism is such strong and dangerous bacteria‚ that ingesting the smallest amount can make individuals sick. More important is other living forms or life like bacteria’s are changing‚ and becoming resistant to the

Unusual features of Shiga toxin producing Escherichia coli O104: H4 outbreak‚ Germany 2011 The Escherichia coli O104: H4 outbreak of 2011 originated in northern Germany and lasted from May through to June of the same year. “The outbreak was characterized by several unusual features: a high incidence in adults (especially women)‚ a greatly increased incidence of the haemolytic–Uraemic syndrome (in approximately 25% of patients‚ as compared with 1 to 15% in previous outbreaks of Shiga-toxin–producing

silicon (Si) reacts with either water vapor (H20) or oxygen (O2) to form silicon dioxide‚SiO2 on the silicon surface. The reaction is represented by following equations: Dry oxidation: Si + O2 → SiO2 Wet oxidation: Si + 2H2O → SiO2 + 2H2 The oxidation process can be implemented through diffusion of either water or an oxygen species through the oxide already formed up which then reacts with the silicon at the Si-SiO2 interface. At high temperature

Staphylococcus aureus (S. aureus) is a gram positive bacterium that when looked at under a microscope it appears to be a cluster of what looks like purple circles. This shape is known as cocci. When grown on a TSA plate‚ Staphylococcus aureus appears to be yellow to opaque in color. S. aureus is known as one of the most resistant bacterium to multiple antibiotics and considered the most pathogenic. Everyone is susceptible to S. aureus with one way of transmission being from foods such as chicken
