Answer :
Final answer:
Bacterial infections are commonly treated with antibacterial drugs, while viral infections pose a challenge due to their intracellular nature. Antihelminthic drugs target worms, and antiprotozoal drugs are specialized for protozoan infections.
Explanation:
Antibacterial drugs are more commonly used to treat bacterial infections due to the structural differences between bacteria and other pathogens. These drugs target specific components within bacterial cells to effectively combat the infection. In contrast, treating viral infections is challenging due to the intracellular nature of viruses, making it harder to develop drugs that selectively target them.
While antihelminthic drugs are effective against various worm infections by killing adult worms, antiprotozoal drugs are specifically designed for protozoan infections, but their effectiveness can vary among different pathogens.
