Poem for a hardworking girl with dreams

She studies all day and night

With books and notes in sight

She has no time for fun or play

She hopes to ace the test someday

She misses her friends and family

She longs for some normalcy

She knows she has to pay the price

She dreams of a future that is nice

She works hard with dedication

She faces each challenge with determination

She does not give up or lose hope

She believes she can cope

She is a student with a goal

She has a fire in her soul

She sacrifices all the joys

She is ready for the exam noise

Gram staining | History | Application |Principle | Procedure

Gram Stain In 1884, Hans Christian Gram discovered a staining technique that could help to visualise the infectious bacteria clearly and can easily study their morphology. In this technique he used crystal violet (the primary dye), Gram’s iodine (IKI, the mordant), an alcohol rinse (decolorizer), Safranin (counter stain ). A Gram stain is a test that checks for bacteria at the site of a suspected infection such as the throat, lungs, genitals, or in skin wounds. Gram stains may also be used to check for bacteria in certain body fluids, such as blood or urine . This color choice provides differentiation between bacteria that stain purple, called gram-positive, and those that stain red, called gram-negative. The difference between gram-positive and gram-negative bacteria is due to the physical nature of their cell walls and how it reacts to the series of reagents applied to the cells . Gram positive bacteria has thick peptidoglyca...
