risk of cross-contamination. This can cause sporadic cases of infectious intestinal disease among customers (Michaels). Earliest studies showed 13% of US coins and 42% of paper money had potential pathogens. They identified E. coli, P. aeruginosa, Klebsiella, Proteus, and Staphylococcus species.Studies after that saw that 18% of coins and 7% of currency tested had organisms that could be disease producing. E. coli and salmonella enteritidis were shown to transport pathogens even a few days after contact

bacterial upper respiratory tract infections (URT) include Streptococcus pneumoniae, Streptococcus pyogenes and Klebsiella pneumoniae 4. This study aims to look at the antimicrobial effect of commercially altered natural products: a capsule containing allium sativum oil 1 mg (equiv. to 3 grams fresh bulb ) and a peppermint dried leaf infusion to determine their efficacy against the test bacteria. Antimicrobial activity of freshly prepared substances (garlic, ginger, mint and lemon) was compared to the

group of multiple bacterium that is very difficult to treat due to the high resistance to several antibiotics, which has earned them the name “Killer bacteria” or “Nightmare bacteria” (Bradford, 2015). This is what led to the Carbapenem-resistant gram negative bacteria study for both inside and outside of the health care facilities, such as Klebsiella pneumoniae and Escherichia coli (E. coli), in an attempt to understand why CRE is antibiotic resistant, and to test if there was any way to slow the

negative bacterium by observing growth patterns of differential and selective media. As shown in the results section, these tests were performed, allowing for the unknown to be determined by comparing the results of the tests with known bacteria. The Gram positive bacteria tested were Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pneumoniae, Streptococcus pyogenes, Streptococcus salivarius, Enterococcus faecalis, and unknown #2. The results of unknown #2 showed that this bacterium

The 12A bacteria were added to the tube by stab inoculation. The tube was incubated at 370 C for at least 24 hours. The results showed that the color of the medium was black with (+) H2S production. The unknown was determined to be positive for motility ( Stevenson University 2011). The next test performed was the nitrate reduction test on bacteria 12A. Nitrate reduction is determined by cultivating organisms in nitrate broth

bacterial skin infections are caused by two bacteria: Staphylococcus aureus and a form of Streptococcus. In the case of Necrotizing Fasciitis, bacteria are usually the cause. Some of the bacteria that have been found to cause this infection include group A Streptococcus, which is group A strep, Klebsiella, Clostridium, E. Coli, Staphylococcus areus, and Aeromonas hydrophila. Because of its effect on skin, Necrotizing Fasciitis is sometimes called flesh-eating bacteria. This infection is very rare but also
