Explanation:
Gram staining is a technique of separation of the bacteria based on the cell wall composition. Steps involved in gram staining are:
1) Primary stain application which is known as crystal voilet, it stains all cells purple/blue.
2) Mordant stain application which is known as iodine solution, is added, and form crystal iodine complex, all cells continue to stain blue/purple.
3) Decoloration step, in this step, we can differentiate gram negative or gram positive bacteria. So, decolorizing agent such as ethanol or acetone extracts blue color from thin walled peptidoglycan layer gram negative bacteria, and gram positive bacteria remain blue/purple because it contains thick walled peptidoglycan layer.
4) Counterstain application in this step safranin red dye stain the gram negative decolorized cells red/pink, and gram positive bacteria remain same blue.
So, if a student is performing a Gram stain of a mixed culture of both E. coli and S. aureus, and he forgets to decolorize with ethanol Both the bacteria should appear blue/purple color.
The impact on the human health as we try to stay ahead of the evolutionary process is actually very bad. It is a fact that the humans are living much longer nowadays than ever before, with the main reasons for that being the well developed medicine and healthcare, much better standard of living, and having less riskier jobs. On the other hand, the human health, without being treated, is actually at an all time low. The immune system is much weaker than it has been, with the main reason being the isolation of the outside world and the higher level of hygiene. The allergies are becoming an ever growing problem because of this, as the immune system doesn't even recognize certain outside bodies are they an enemies or not. The constant radiation for numerous sources has caused development of numerous diseases. The old age has increased the percentage of diseases such as cancer, Alzheimer, Parkinson, or sclerosis. The less active life-style and food over saturated with fats and sugars has caused numerous health problems as well. All in all, the human health has become dependent on the pharmacy and its products, and without it it will suffer badly.
