Spontaneous bacterial peritonitis: an acute bacterial infection of ascites fluid. Although a bacterial infection the infecting agent is not easily identified. Spontaneous bacterial peritonitis is commonly seen in patients receiving peritoneal dialysis due to contamination of dialysate. Signs and symptoms: a wide range of symptoms including diarrhea‚ worsening encephalopathy‚ ascites that do not improve following administration of diuretic medication‚ worsening or new renal failure and ileus

conjunctivitis can occur in one or two of a person’s eyes. It tends to cause a watery discharge while conjunctivitis caused by bacteria causes a thicker discharge. Both are transmitted to another eye in the discharge. Children are primarily affected by bacterial conjunctivitis‚ possibly because it is more transferable in a location like school. People are at a higher risk of developing conjunctivitis if they use contacts. Those who come in

For this experiment‚ there will be an optimal point for each factor. I believe that the optimal temperature for the enzyme sucrase will be 37°C because that is the point where the temperature increases the rate of reaction to its greatest point without denaturing it. For the pH test‚ I think that the optimal pH for sucrase will be the pH of 7 because it is neutral so it won’t affect the charge in a negative or positive way. For the denaturation test‚ I think that the optimal treatment for the enzyme

OBSERVATION OF BACTERIAL CELLS VIA MICROSCOPE In this experiment‚ we have learned several basic molecular biology techniques. Here they are; Simple staining: Only one type of dye used for simple staining and it stains all cells the same color. Creating contrast between cell and background to observe cell morphology is aimed. Differential staining: A differential stain uses more than one dye and stains different kinds of organism with different colors. Positive staining: If cell itself is stained

diagram above.) 2.Secondly I will measure the required amount of Zinc (Zn) on a weighing scale‚ again for precise accuracy. I will then measure the starting temperature using a thermometer. Next I will pour the Zinc into the test tube containing CuSO4. 3.Finally I will measure the final temperature using a thermometer and record the temperature rise in °c. (I will carry out all my experiments under lab safety precautions.) Variables *I will vary the mass of Zinc‚ & use the following Zinc weights:

Investigating the effect of temperature on the action of a protease enzyme on exposed developed film Plan Aim: The aim of the experiment is to find out what effect temperature has on the action of a protease enzyme on exposed developed film. Enzymes are biological catalysts. They are made in livings things built up by amino acids to make protein. Enzymes are able to speed up reactions and can repeat reactions. There are various factors that affect the activity of enzymes they are: "Y Temperature "Y pH

Alyse Rose Microbiology Lab Bacterial Unknown March 25‚ 2013 Bacterial Unknown Report Each student was given an unknown bacteria to figure out. I was given the unknown bacteria S38. Everybody is supposed to do all sorts of test to identify the bacteria. The first thing I did was smear my bacteria on a liquid medium. I then proceeded to incubate the medium for 24-48 hours. 1. GRAM STAIN The next step I took in finding my unknown bacteria was to gram stain it. This is used to differentiate

Place the first food item under the ring stand. 6. Set the food on fire then quickly place the can on the ring stand above the burning food. 7. Once the food has extinguished take the temperature of the water in the can. 8. Weigh the food that has been burned. 9. Pour out water that is in the can. 10. Repeat steps 2-9 for

larvae had formed their chrysalises each student put 1 of their containers into a cold climate approximately 45°F‚ 1 in a warm climate approximately 85°F and 1 stayed out at room temperature approximately 72°F. The larvae spent a total of 5 days in each climate‚ and then they were removed and brought back to room temperature. Then the waiting game started to see how long it took each larva to go through metamorphosis and emerge as a butterfly. Based on the data that was recorded it looks like the larvae

Introduction: Bacteria are microscopic‚ single-celled organisms. Their genetic information is encoded in one large chromosome. It can also be found in plasmids which are small circular pieces of DNA that contain important genetic information for the growth of bacteria. In nature‚ this information is often a gene that encodes a protein that will make the bacteria resistant to an antibiotic. The reason for this protein being made within the bacteria is because of how bacteria usually grow in the same
