The catalase test is used to differentiate staphylococci (catalase-positive) from streptococci (catalase-negative). The enzyme‚ catalase‚ protects the bacteria from the toxic by-products of oxygen metabolism. This enzyme is produced by bacteria that respires using oxygen. The catalase-positive bacteria include strict aerobes. Catalase-negative bacteria may be anaerobes‚ or they may be facultative anaerobes do not respire using oxygen as a terminal electron acceptor. The test reaction is very fast

salts in urine. To test this we used different chemicals that would react with one of the four items above showing either a high concentration or low concentration within the urine. By using a solution called silver nitrate we could test whether or not salt was present in the urine. If the urine turned a cloudy white after adding the silver nitrate the urine had a high concentration of salt. To test for amino acid we used a chemical called biuret solution. If the urine turned the color purple it means

from when he was born in 1943 through his book “life on the color line.” Gregory starts out life living officially as a white child with his mother and father for his first ten years. After his mother left to be away from his abusive father‚ Gregory went with his father to live with his father’s family. Since Gregory was part black‚ and he was now living with his black relatives‚ he was then known officially as a black child. This changes his life by giving him less opportunities and more scrutiny

I have learned to indentify personal VABEs within my own experiences and in everyday life. The first situation that occurred where I was able to identify my personal VABEs took place a couple of weekends ago. I was at a bar with a large group of my friends celebrating our mutual friend’s 21st birthday. We were obviously drinking alcoholic

What is urodynamic testing? Urodynamic tests are done to determine how well your lower urinary tract is working. The lower urinary tract includes your bladder and the tube that empties your bladder (urethra). When your kidneys filter your blood‚ urine is stored in your bladder until you feel the urge to pass urine (urinate). Urination requires coordination between the nerves and muscles of your bladder and urethra. When your lower urinary tract is working well‚ you should be able to: Start urinating

After conducting the trials for each beaker and each bag my hypothesis of each of the trials were correct. Every outcome I predicted occurred to each beaker and each bag. Beakers 1 and 2 decreased in mass while beaker 3 stayed constant. Beaker 4 actually increased in mass as well. Bags 1 and 2 increased in mass while bag 3 stayed the same. Bag 4 resulted in a decrease in mass. The results I got from this experiment do support what I predicted before the trials. Above you can see a specimen of an

a smear was prepared by use a sterile transfer loop that been flamed to removes some bacteria from slant agar and placed on the slide; mixed with one drop of water and let air dried. After dried‚ heat fixation the slide by passed the slide over a flame quickly 2-3 times to stick bacteria to the slide. Next‚ the smear was sequence covered with crystal violet‚ iodine‚ 95% ethanol‚ and safranin; each reagent was rinsed with water after 1 minute. When decolorized with 95% ethanol‚ the smear was slowly
