1) TITLE (2pt): Testing antimicrobial props in soaps 2) INTRODUCTION (6 pts): In this experiment we wanted to test how effective different types of soaps against E. Coli. For this experiment we were interested in looking at antimicrobial soaps vs. non-antibiotics soaps in their effectiveness to kill E. Coli. The protocol that we used was the Kirby Bauer technique. This technique was used to test the antimicrobial properties of each soaps. (“Kirby-Bauer” 2015). 3) METHODS (6 pts): We first started

This article is about public and private swimming pools being contaminated with E. coli. Chlorine is not doing its job in sanitizing the human waste in the swimming pool. Human waste seems to refuse being sanitized. The Centers for Disease Control (CDC) concluded that the E. coli came from one major primary source; swimmers pooping in the swimming pool. Researchers say such contamination is due to swimmers not rinsing themselves off before going in the pool. Scientists say a person carries about

RESULTS AND DISCUSSION E. coli and S. aureus were tested to determine effectiveness of photodynamic inactivation with the use of methylene blue as photosensitizer and blue LED as alternative light source. Table 1 shows the resulting number of colonies for each replicate of every treatment per bacteria tested. Each of the treatments was averaged to get the mean number of colonies per treatment. All experimental setups were produced in quintuplicate‚ however only three of the five replicates were

data on the growth of Escherichia coli (E. coli) and to monitor how it grows under certain conditions. It has been demonstrated that the levels of glucose and dissolved oxygen were found to affect the rate of growth of E. coli proportionally with a lack of oxygen resulting in the lowering of the pH. In this experiment the growth of E. coli was studied at constant temperature (37 0C) at which it grows ideally. Experimental results for the growth of Escherichia coli showed good agreement with theory

by the emergence of Shiga toxin-producing Escherichia coli (Callaway et al.‚ 2013). Specifically‚ Shiga toxin-producing E. coli O157 is a foodborne pathogen of significant public health importance. It can cause mild to bloody diarrhea in humans which may progress to hemolytic uremic syndrome (Centers for Disease Control and Prevention‚ 1993; Hussein‚ 2007) that can be fatal in children‚ the elderly and immunocompromised individuals. E. coli O157 is also responsible for an estimated 63‚153 illnesses

providers work more efficiently. One of these medical advancements would be a mutated E. coli. So how exactly can a mutated E. coli be an advancement? Well what scientist recently discovered is that this certain mutated bacteria actually will color urine to help diagnose medical diseases. So perhaps this mutated E. coli can make diagnosing certain issues a quicker process than before. One disease this E. coli mutant helps diagnose is diabetes.
