A: Does the bacteria and viruses?
Q: Bacteria are single-celled organisms that can normally be found inside and outside of our entire body, except in the blood and cerebrospinal fluid (spinal cord). Most bacteria are harmless. In fact, some bacteria are actually beneficial. However, there are pathogenic bacteria that can lead to diseases such as strep throat caused by streptococcal bacteria and a number of ear infections. Viruses are smaller than bacteria. The virus can survive outside the body cells. Viruses cause disease by invading healthy cells and proliferate.
A: What kind of infections caused by viruses and should not be treated with antibiotics?
Q: Viral infections that should not be treated with antibiotics include:
- Common Cold
- Cough and bronchitis
- Throat Infection (except that caused by streptococcal bacteria)
- Some ear infections
A: What is an antibiotic?
Q: Antibiotics, also known as antimicrobial drugs, are drugs that fight infections caused by bacteria. Alexander Fleming discovered the first antibiotil, penicillin, in 1927
. After the first use in the 1940s, antibiotics transformed medical care and dramatically reduce illness and death from infectious diseases. The term "antibiotic" originally intended for a natural compound produced by a fungus or other microorganisms that kill bacteria that cause disease in humans and animals. Some antibiotics may be synthetic compounds (not produced by microorganisms) that can also kill or inhibit microbial growth. Technically, the term "antimicrobial agent" means both natural and synthetic compounds, but many people use the word "antibiotic" refers to both. Although antibiotics have many beneficial effects, its use is not rational contributed to the problem of antibiotic resistance.
