Which statement is true regarding narrow spectrum antibiotics?
They are effective against gram-positive bacteria only. This is not true because some narrow spectrum antibiotics can also target gram-negative bacteria, such as aminoglycosides.
They are effective against gram-negative bacteria only. This is not true because some narrow spectrum antibiotics can also target gram-positive bacteria, such as vancomycin.
They are effective against one type of organism. This is too restrictive because narrow spectrum antibiotics can work against more than one type of organism, such as penicillins that target both streptococci and staphylococci.
They are effective against a few types of organisms. Narrow spectrum antibiotics are antibiotics that work against a limited range of bacteria, usually either gram-positive or gram-negative. They are more specific and less likely to cause resistance or disrupt the normal flora.
