Streptococcus (group A strep) and Staphylococcus aureus are one of the main causes of necrotizing fasciitis‚ one of the rarest causes of necrotizing fasciitis is Aeromonas hydrophila which is a gram negative bacterium and is usually associated with brackish waters such as lagoons‚ marshes‚ deltas and estuaries this strand of bacteria is very resistant to antibiotics

Not all of the tests were performed on every culture‚ however‚ as some of the tests were used only for gram (+) or gram () bacteria‚ while others were even more specific and used only for cocci bacteria. The tests performed and what constitutes a positive and negative test are as follows. The oxidase test was performed only on gram (-) bacteria and was used to test for the presence of cytochrome oxidase. Living bacteria were placed on a paper towel and saturated

examine the effect different disinfectants and antiseptics‚ which are used to decrease the number of microbes‚ on Escherichia coli and Staphylococcus aureus. The effectiveness of the chemical agent was determined by the size of the zone of inhibition around the disc incubated on soft nutrient agar seeded with the two bacteria on separate plates. For E. coli‚ a gram negative organism‚ the zone of inhibition was the largest with Lysol (0.2mm). Next‚ Scope has slightly smaller zone of inhibition‚ 0

It can result from a variety of causes‚ including infection with bacteria‚ viruses‚ fungi‚ or parasites‚ and chemical or physical injury to the lungs. Pneumonia is an irregular inflammatory condition of the lung. It is often described as inflammation and abnormal fluid filling of the

order to identify an unknown bacterium. An unknown bacterium was handed out by Dr. Honer. The appropriate tests were prepared and applied. The first procedure that was done was the gram stain. Under a microscope‚ if the gram stain is purple‚ the bacterium is gram positive‚ if the stain is red‚ it is gram negative. The next test was the fermentation tests for glucose‚ sucrose and lactose. If an organism is able to ferment the carbohydrate‚ there will be acid produced‚ which will turn the broth

More than 50 new types of CAMP’s have been identified in the komodo dragon blood.Most of them just ward off bacteria‚ about 8 of them are able to fight bacteria that are currently resistant to antibiotics.7 of them killed Pseudomonas aeruginosa and Staphylococcus aureus bacterial strains(which are currently resistant to antibiotic.)While one fought off only P.

unknown material was tube number twenty. I did a gram stain‚ oxidase test‚ and used three different medias to narrow down and identify my unknown organism. The first step I took in identifying was a gram stain. This gram stain would reveal whether my organism is gram positive or gram negative which would narrow my choices from fifteen options down to six. After completing the gram stain‚ my unknown was the color pink. This revealed my unknown as being gram negative. I also used the microscope to identify
