What is the name of the bacteria that produces antibiotics?

Is cephalosporin a penicillin?
Cephalosporins are related to penicillins. They both belong to a larger class called beta lactams. Like penicillins, cephalosporins originally came from a fungus—C ephalosporium. There are five generations of cephalosporins. Each generation covers different types of bacteria. As a result, the class can treat a variety of infections, from strep throat and skin infections to very serious infections like meningitis. Because they are related to penicillins, some people with penicillin allergies may also react to cephalosporins. Other common side effects include diarrhea, nausea, heartburn, and abdominal pain. Examples of cephalosporins include:
What is the role of antibiotics in the treatment of bacterial infections?
It is the most important type of antibacterial agent for fighting bacterial infections. Antibiotics are widely used in the treatment and prevention of such infections.

When were antibiotics invented?
The first modern-day antibiotic was used in 1936. Before antibiotics, 30 percent of all deaths were caused by bacterial infections. Thanks to antibiotics, previously fatal infections are curable. Today, antibiotics are still powerful, life-saving medications for people with certain serious infections. They can also prevent less-serious infections from becoming serious. Most antibiotics are only available with a prescription from your doctor. Some antibiotic creams and ointments are available over the counter.
How do antibiotics help?
Antibiotics help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing. The word antibiotic means “against life.” Any drug that kills germs in your body is technically an antibiotic.
Why are antibiotics so effective?
When prescribed appropriately and taken correctly, antibiotics can be very effective. They can shorten the time you are sick and keep the disease from spreading to others. Perhaps because they seem so effective, doctors may have a tendency to prescribe them too often, even when there is not anything for them to treat and you would have gotten better just as quickly without them. Sometimes this is done in the hopes of preventing bacterial infection. However, over time, many bacteria adapt to resist antibiotics, making these medications less effective or unable to work at all. This occurs even in bacteria not responsible for the illness that just live in your body.
What is the most dangerous bacteria that can cause infections in the lungs, skin, blood and bones?
Methicillin-resistant Staphylococcus aureus (MRSA)— These dangerous bacteria can cause infections in areas such as the lungs, skin, blood and bones.
Why are antibiotics resistant?
The most important cause of antibiotic resistance is inappropriate use or overuse of antibiotics. As much as 30 percent of antibiotic use is thought to be unnecessary. This is because antibiotics are often prescribed when they aren’t needed.
Can antibiotics cause side effects?
All medications have side effects, including antibiotics. Antibiotics are medications that treat infections by killing bacteria or other organisms or slowing their growth. An antibiotic side effect occurs as an unwanted reaction that occurs in addition to the desirable therapeutic action of the antibiotic you are taking. Side effects of antibiotics can range from mild allergic reactions to severe and debilitating adverse events. When used appropriately, most antibiotics are relatively safe with few side effects. However, some side effects may interfere with your ability to finish the medication. In these cases, you should contact your doctor.
