Biochemical tests are often used to determine the identity of bacteria and differentiate between its species. There are numerous types of tests meant to detect key characteristics such as morphology, stain, motility, fermentation pathways used, oxygen requirements, enzymes present, and redox tests used. By conducting these tests with aseptic techniques, one can usually narrow down an unknown bacterium to its family; with the help of dichotomous keys and Bergey’s Manual of Determinative Bacteriology

Microbe’s Effect on Humans Research at McMaster University has linked the bacteria found in a person’s gut to depression and anxiety (Gut). People that have irritable bowel syndrome or late onset autism had atypical gut bacteria. Stephen Collins, Associate Dean of Research and professor at Michael G. DeGroote School of Medicine, and Premysl Bercik, an assistant professor, conducted the research on healthy adult mice and mice that showed aggressive behavior at Farncombe Family Digestive Health Research

A recent discovery offers hope for the treatment of drug -resistant strains of bacteria jeopardizing the lives of hundreds of thousands of people. The majestic Sweet Chestnut tree could be the key to halting a modern scourge. Drug resistant Staphylococcus aureus (MRSA ) has vexed the medical community for decades. Among the medical hazards, the bacterium known as staph comprises the immune systems of hospital patients, thereby prolonging the healing process. Once contracted, the pathogen is

Successful Policy Models to Replicate Antibiotic prescriptions must to be regulated and there is some evidence that exists showing that regulations would be successful. Around the 1990’s a hospital in Athens, Greece, the Laiko General Hospital, implemented a new policy for antibiotics (Nelson, n.d.). Some of the most popular antibiotics could be ordered only after a physician filled out an order form outlining the request (Nelson, n.d.). From there, the request was received and reviewed by infectious

looking at lung tissues, he discovered that the staining method was adhering better to some bacteria than others. (Allen , Anderson , Nester , & Salm , 2016) This led to the discovery that two different types of bacteria were causing the pneumonia. By discovering that the staining method showed two different types of bacteria, the technique became the Gram Staining method. The technique allowed for the bacteria to either show results for gram positive or gram negative. To determine the different characteristics

"Perhaps one of the most compelling facts about penicillin is that it went on to save hundreds of thousands of lives during World War II, and has continued to forestall infectious diseases ever since." (Source One, lines 35-38) The strongest drug a person could receive against infections is penicillin. People know what this drug is, but not how it was discovered, developed, and mass produced. Penicillin, one of the most spectacular advances in the medical universe, was discovered and developed by

Three different test tubes were used to test for the effect of alkalinity and temperature on the structure of DNA. The control of the experiment was test tube A because no variables were tested. This test tube was necessary in the experiment because it behaved as a baseline to compare with the results of the experimental variables. Test tube B was exposed to a high temperature (100°C) to observe the effect of high temperatures on DNA structure while test tube C was exposed to an alkaline pH through
