Prokaryotic organisms have existed for billions of years. These prokaryotic cells have gone through enough environmental changes to learn how to adapt quickly. As small organisms that reproduce rapidly, bacteria cells are the most abundant organisms on earth and the most important. Gram staining is used by scientists to help identify and classify bacteria due to the fact that it is difficult to discern unstained bacteria through light microscopes (1). Since bacteria are small organisms that are…

If left untreated, the infection can spread to other parts of the body and may be life threatening. It is best to seek attention immediately. Etiology Cellulitis occurs when bacteria, most commonly Staphylococcus aureus (S. aureus) and Streptococcus pyogenes (S. pyogenes), or by a wide variety of bacteria of external bacteria [10] Cellulitis can occur as an…

Bacterial identification is crucial to the healthcare setting in that it helps prevent or reduce disease. Multiple tests were conducted in attempt to identify the unknown microorganism that was swabbed from a cheek, and their materials, methods and results were described. The goal of the unknown lab experiment was achieved by identifying the genus and possible species through interpretation of the results found. Microbiology is the study of microscopic organisms. These organisms are virtually…

John F. Kennedy’s life is not defined by his assassination. Though many people know him by that, his life had many interesting ups and downs. At one point in his life, he attended one of the greatest schools in the nation at the time. Kennedy had many loved ones in his family pass away through out his lifetime. He also faced many surgeries and diseases that were dangerously life threatening, such as: Scarlet Fever, Addison’s Disease, and life threatening surgery to relieve pain he had in his…

Lactobacillus is the most commonly used bacterial species (Swyers et al. 2008). A study conducted by Al Jassim et al. recorded that several species of Lactobacillus were located throughout the equine gastrointestinal tract. This concludes that these microbes have the ability to adapt to pH changes and survive in different environments. L. mucosae and L. salivarius were found to be the most abundant. L. salivarius, specifically, was cultured from the stomach, colon, and rectum, suggesting its…

1938 when he viewed Fleming’s paper on the mold. Alongside Florey was Doctor Ernst Chain who fought with Florey on who deserved credit for this new drug. During the summer of 1940, Chain and Florey began experiments on fifty mice infected with streptococcus. In this experiment, twenty-five mice were given penicillin and the other twenty-five did not. The results of the experiment showed that the mice given penicillin were cured and the others died a slow, painful death. This experiment showed…

In this lab report a number of tests and results will be discussed. Unknown labs are performed for many reasons ranging from figuring out the causative agent in a diseased patient, to knowing the correct microorganism to use when making certain foods and antibiotics. Unknown labs are a key to testing the knowledge a student has gained throughout the course. Materials: Microscope Bunsen Burner Beaker Test Tube Holder Test Tube Clothes pin Striker Loops and Needles Distilled Water Crystal…

Can cavitation bubbles reduce the number of non-pathogenic E. coli on an ice cream scoop and the amount sloughed off into the water around the scoop? The results supported the alternate hypothesis which stated that both the scoop and the water, when subjected to cavitation bubbles, would show a significant reduction or change of E. coli bacteria. All statistical analysis was completed using the results from a Tukey-Kramer test. Overall, the statistical alternate hypothesis (μ≠μ) was supported…

sweetened with a substance called xylitol, sorbitol, and maltitol has been shown to actually reduce cavities and not cause tooth decay. The reason for this is because the material in this sugar free gum does not include the harsh substance of streptococcus mutans, which are bacteria that break down tooth enamel. This is because the food and sucrose take an affect on the teeth causing demineralization, but when added with calcium lactate it reduces this. Many times this calcium lactate is placed…

Discussion The research methods in the studies reviewed improved in sophistication and clarity over time from 2011 to 2016. Three of the studies determined that antibiotics resulted in a risk for increased BMI in boys but not in girls (Ajslev et al., 2011; Azad et al., 2014; Murphy, et al., 2014). In general, repeated exposures to antibiotics (Saari et al., 2015; Schwartz et al., 2016; Scott et al., 2016) or broad-spectrum antibiotics (Bailey et al., 2014), in particular macrolides (Saari et al…
