Antibiotics Flashcards

All 4 cards in this deck

Why can antibiotics be used to treat bacterial infections?: They inhibit processes in bacteria, so the bacteria are killed or stop growing/reproducing, but they do not damage the host cells.
Give one example of a bacterial cell process that an antibiotic can inhibit.: Making the bacterial cell wall (cell wall synthesis).
True or false? Antibiotics can be used to treat influenza and HIV.: False. Antibiotics only work on bacteria; influenza and HIV are caused by viruses, which do not have the cell processes antibiotics target.
Why can chlamydia be treated with antibiotics?: Chlamydia is caused by bacteria, which are killed/inhibited by antibiotics.
