microbiology laboratory class for the identification of an unknown bacterium. Hypothesis By slowly narrowing down the bacteria by each test‚ I will be able to conclude the unknown bacteria by its special characteristics. MATERIALS AND METHODS An unknown labeled as #54 was given out by the lab instructor. The methods that have been learned thus far for identifying bacteria have been applied to this unknown. Procedures were followed as stated in the course laboratory manual‚ unless otherwise

Clinical Decision Making A complete medical history was obtained from the patient. Following a discussion of her concerns‚ a physical exam‚ including a pelvic and bimanual exam was performed. Swabs of the vaginal area were collected and placed under the microscope. The results were concurrent with the suspected diagnosis of bacterial vaginosis. The physician explained the results of the swab samples and offered the patient different treatment options. Pathophysiology Bacterial Vaginosis (BV) is

Some bacteria‚ which contaminate food‚ include Staph Aureus‚ E. coli enteritis‚ salmonella‚ shigella‚ campy lobacter‚ cholera‚ botulism‚ Listeria‚ Yersinia‚ Salmonella‚ Clostridium perfringens‚ Campylobacter‚ Listeria monocytogenes‚ Vibrio parahaemolyticus‚ bacillus cereus‚ and Staphylococcus.

As technology progresses we are better equipped to deal with bacteria and viruses. In spite of these advances in medicine and technology‚ “pathogenic bacteria‚ fungi‚ viruses‚ protozoan‚ and worms continue to plague every society” (Wright‚ Boorse‚ 2014). One such problem responsible for over 3 million deaths in 2008 alone is acute respiratory infections‚” (Wright

Foodborne Illness What is Foodborne Illness? According to a medical dictionary‚ foodborne illness is an acute gastrointestinal infection caused by consuming food contaminated with pathogenic‚ bacteria‚ toxins‚ viruses‚ prions or parasites. Such contamination was caused by improper food handling‚ preparation or storage of food. Contacts between food and pests‚ especially flies‚ cockroaches and rodents are a further cause of contamination of food. Foodborne illness can also be caused by adding

nanoparticles that polymerize into structures that are able to attack MRSA bacteria without harming the healthy tissue around it. Once these polymers come into contact with water in or on the body‚ they self assemble into a new polymer structure that is designed to target bacteria membranes based on electrostatic interaction and break through their cell membranes and walls. The physical nature of this action prevents bacteria from developing resistance to these nanoparticles or other antibiotics. The

The ability of humans to manipulate DNA is a mixed blessing Genetically modified organisms are made moving the DNA from one species to another. DNA contains genes which code for proteins. For plants and bacteria; restriction enzymes are used to cut a DNA segment from a desired gene source and a bacterium plasmid. They are joined using ligase enzymes and inserted into the plant chromosome or host bacterium. For animals the recombinant DNA is injected into an embryo and transferred to a recipient
