Can antibiotics cause disease?
Some germs that were once very responsive to antibiotics have become more and more resistant. This can cause more serious infections, such as pneumococcal infections (pneumonia, ear infections, sinus infections, and meningitis), skin infections, and tuberculosis.
Is an agent that causes disease?
A pathogen or infectious agent is a biological agent that causes disease or illness to its host. The term is most often used for agents that disrupt the normal physiology of a multicellular animal or plant.
What infectious agent causes the disease?
Infectious diseases are caused by microorganisms such as viruses?, bacteria?, fungi or parasites?. Microorganisms that cause disease are collectively called pathogens.
What are the 3 types of causative agents for diseases?
Infectious diseases can be caused by many pathogens, including bacteria, viruses, fungi, and parasites that may cause illness and disease.
Are there different types of antibiotics for different infections?
There is no one type of antibiotic that cures every infection. Antibiotics specifically treat infections caused by bacteria, such as Staph., Strep., or E. coli., and either kill the bacteria (bactericidal) or keep it from reproducing and growing (bacteriostatic).
How are antibiotics used in the human body?
They either kill bacteria or stop them from reproducing, allowing the body’s natural defenses to eliminate the pathogens. Used properly, antibiotics can save lives. But growing antibiotic resistance is curbing the effectiveness of these drugs.
How is antibiotic resistance a problem in medicine?
An antibiotic cannot target and kill viruses, as it does in case of bacteria. So when you use antibiotic medications to cure viral attack, it becomes ineffective. In addition to this, it creates another set of problems known as antibiotic resistance. This refers to the situation where bacteria grow strong or resistant to the power of antibiotics.
Do you have to take an antibiotic if you have an infection?
However, it is important not to use an antibiotic for an infection unless your doctor specifically prescribes it, even if it’s in the same class as another drug you were previously prescribed. Antibiotics are specific for the kind of bacteria they kill.
What kind of problems can be caused by overuse of antibiotics?
Among those that are becoming harder to treat are pneumococcal infections (which cause pneumonia, ear infections, sinus infections, and meningitis), skin infections, and tuberculosis. In addition to antibiotic resistance, overusing antibiotics can lead to other problems.

What happens to good bacteria when you take antibiotics?
Antibiotics kill many different bacteria, even the good ones that help keep the body healthy. Sometimes taking antibiotics can cause a person to develop diarrhea due to a lack of good bacteria that help digest food properly. In some cases, bad bacteria, like Clostridium difficile (or C diff ), may overgrow and cause infections.
