Answers
Answer:
Antibiotics are medicines which fight bacterial infection. Utilizing microbes such as fungi and bacteria, antibiotics attack the pathogens in our bodies that make us sick. They accomplish this by breaking the cell wall of the bacteria, disrupting protein synthesis, and dismantling DNA strands of the bacteria.
Explanation:
A drug used to treat bacterial infections. Antibiotics have no effect on viral infections. Originally, an antibiotic was a substance produced by one microorganism that selectively inhibits the growth of another.,
The main types of antibiotics include: Penicillins - for example, phenoxymethylpenicillin, flucloxacillin and amoxicillin. Cephalosporins - for example, cefaclor, cefadroxil and cefalexin. Tetracyclines - for example, tetracycline, doxycycline and lymecycline..
Antibiotics work by either selectively killing (bactericidal) or inhibiting the growth (bacteriostatic) of bacteria. Infections with a high bacterial burden, such as those seen in infective endocarditis, require treatment with antibiotics with rapid bactericidal activity.
