Are bacteria larger than viruses?
no bacteria is larger than viruses
Are viruses smaller or bigger than bacteria?
there are some bacteria that approach the size of larger viruses but, viruses are smaller than bacteria
Protozoan diseases are easy to treat?
They can be a bit harder to treat than bacterial diseases, because on a cellular level, protozoa are more like humans than bacteria are like humans.
Can Antibiotics treat a virus?
No. Antibiotics only treat bacteria - and each antibiotic has a different group of bacteria it can treat. Antivirals such as acyclovir, foscarnet, and ganciclovir treat some viruses, and others have no treatment other than supportive therapy: fluids, fever control, etc.
Why are viral infections more difficult to treat than bacterial infections?
That is a difficult one. It depends on the virus and the bacteria. Most viruses cause self-limiting diseases, that are treated with supportive measurements. Other viruses, such as Influenza, Cytomegalovirus and Herpes, and HIV, can be treated with specific drugs. There are different drugs that treat different types of bacteria, with more or less success. But remember that viruses and bacteria are live organisms, and they can and do develop resistance to the drugs that kill them. Even more, bacteria can even pass on the learned resistance to other bacteria.
Why are viruses and eukarotic pathogens more difficult to treat than prokaryotic pathogens?
I think it's because eukaryotic pathogens are more similar to host cells. So, if there are more similarities, it is harder to treat.
Are bacteria smaller than a virus?
Viruses are non-living entities that show characteristics of living beings inside another living cell. Viruses consist of genetic material surrounded by protein coat. They lack organelles or membranes. Thus, they are very much smaller than bacterial cells which have membranes, and sometimes even organelles. In fact, many viruses inhabit bacterial cells. They are called bacteriophages. The smallest bacteria are in the order of .3 micrometers, while the largest viruses are in the order of 400 nanometers. A virus is smaller than bacteria A virus is smaller than bacteria
Is a virus bigger or smaller than bacteria?
Bacteria and viruses can breed. i.e. When bacteria breeds, they form large colonies visible to the naked eye When viruses breed, they become more deadly or mutate but are still virtually invisible to the naked eye.
How can you tell the difference between bacteria and viruses?
The difference is that viruses are smaller than bacteria. One more major difference is that bacteria are living things whereas viruses are non living things.
What is the superbug?
Super bugs are a class of viruses and bacteria that are resistant or immune to antibiotics. They are a growing concern because they are appearing faster than we can make drugs that can treat them.
Is virus are much smaller then bacteria?
Yes, viruses are smaller than bacteria.
Why can antibiotics treat flu-like symptoms caused by bacteria but are ineffective against flu?
Because the way antibiotics treat those symptoms is by killing the bacteria that cause them. If the symptoms are caused by viruses, then antibiotics can't help since they are not made to be able to "kill" viruses, just bacteria. Flu viruses are not really living organisms like bacteria are. So viruses must be inactivated rather than killed. Antibiotics can neither kill nor inactivate viruses. They are created to be used to kill only specific bacteria, they do not kill every kind of bacteria, either. That is why there are so many different kinds of antibiotics. Antibiotics can treat flu-like symptoms caused by some bacteria, because the right antibiotics can kill bacteria. So although flu like symptoms are similar to those of the flu, they are caused by different microbes so are not cured in the same way.
