What stains reveal specific molecules in plants?‚ Which stains show the molecules distribution within the cell in animals?‚ and What macromolecules do they actually reveal? In lab we worked with several different stains. The most commonly used stains were fast green which is used to stain proteins. Periodic acid-Schiff stain (PAS)‚ which is used to stain carbohydrates. Feuglen stain which is used to stain DNA. Sudan Dye III which is used to detect lipids and Azure B which is used to stain DNA and

infections are caused by gram-negative bacilli‚ identification and sensitivity testing are of primary importance. Usually‚ identification of bacteria and determination of their sensitivity to specific antimicrobial drugs are done after the initial gram stain analysis. Most frequently‚ the identification of a specific organism must be accompanied by a sensitivity study. Also due to the changing patterns of resistance in other bacteria to antibacterial agents‚ sensitivity studies are essential. Clinically

One afternoon I was walking home from my friend’s house along the railroad tracks barefoot and suddenly I felt a sharp prickly pain shooting up my leg‚ I look down and realized I had stepped on a broken piece of glass. When I got home my mother told me I should go get a tetanus immunization in case I had contracted tetanus. I did not know what tetanus is‚ so then I decided to do some research. Tetanus‚ also more commonly known as Lockjaw‚ is caused by Clostridium tetani. Lockjaw can occur as a bacterial

to stain microorganisms was a significant advance in microbiology. Stains serve purposes such as it differentiate microorganisms from their surrounding environment and it allows detailed observation of microbial structures at high magnification.

Our problem is that many types of beverages stain or damage your teeth. So instead of using our teeth for the experiment‚ we are using egg shells. Many beverages are really bad for your teeth and we want to see which ones are the worst and the best. For this project‚ the type of beverages we will be using are Pepsi‚ Coca Cola‚ tea‚ coffee‚ grape juice‚ and sports drinks. Tea has many great health bonuses ‚ but is bad for your teeth. The tea color or type depends on how stained your teeth will be
