People are exposed to germs by way of touching unclean surfaces or coming in contact with people who are either sick or don't practice proper hygiene. People who are sick and don't cover their mouths when they cough or sneeze expose more people to germs.
The rats are harmful to man because when there is heavy rain (Storm) there will be flooding and the flood will have many germs and urine of the rats. If you are exposed to these germs you will get Leptospirosis.
Most people who are not vaccinated against the swine flu or who have not had the swine flu will get it if exposed to it. Those who have had the vaccines will be immune.
Preventative measures like proper handwashing and cleaning the physical environment either kill or keep germs from multiplying. When germs infect the body, antibiotics can kill or control the infection/germs. However, because germs have been repeatedly exposed to the agents we use to combat germs, many germs have mutated and no longer respond to the usual agents. This is why doctors have become reluctant to give antibiotics.
That would depend on if the piano key has ever been exposed to the air. If it has, then yes, there are more than likely germs on it. If the key is a replacement and is still in the packaging, it may be clean.
Staph and strep are different germs, and will not be confused by culture in the lab.
As long as anything is exposed to air it can be contaminated by microbes. This includes cups and plates.
Pha! Um interesting question. Well, scientifically it depends where you live. If you live in ,say, America you will be walking in shoes and socks, so your feet will not be exposed to the ground. and If you can imagine an Elephants Rear has been exposed to sun poo and Germs that are most probably exlusive to Africa ! so No i doubt it very much :)
germs are everywhere, and they are tiny tiny tiny. unfortunately we can't go magic school bus and shrink and laser them to death...and if we did kill all the germs, if one germ managed to return, nobody would have any immunity to anything and it would be an epidemic. germs aren't really that bad, you're exposed to millions each day without feeling a thing
This is because the hands are the most exposed part of the body that are carriers of germs that can later cause infection. The toilet carriers a lot of germs on the flash handle or door knobs. This is because the toilets are used by more than one person. This germs can cause infections. That is the reason as to why one should wash hand should be washed after visiting the toilet.
Ultraviolet (UV) light can help visualize germs because many microorganisms, including bacteria and viruses, fluoresce when exposed to UV light. Certain dyes or stains can be applied to the surface or medium containing the germs, making them emit visible light under UV illumination. This property allows for the identification and observation of germs that are otherwise invisible to the naked eye. However, it's important to note that while UV light can highlight the presence of germs, it does not provide information about their viability or specific types.
The number of germs that can come into contact with a person at once varies widely depending on the environment and situation. For instance, touching a contaminated surface can transfer thousands to millions of bacteria and viruses to your skin. Additionally, airborne pathogens can also be inhaled in significant numbers, especially in crowded or unhygienic settings. Overall, it's possible to be exposed to a staggering number of germs simultaneously.
The flask that was not exposed to air/germs and remained sealed represents the control in Louis Pasteur's experiment. This flask helped to demonstrate that it was the air/germs that caused the spoilage and not just the broth itself.
