Mechanism of Action

Microorganisms, including protozoa and bacteria, pose significant threats to human health. Antiprotozoal and antibacterial agents play a crucial role in combating these infections. Understanding their mechanisms of action is essential for effective antimicrobial therapy.

Antiprotozoal Properties

Protozoa are eukaryotic microorganisms that cause diseases such as malaria, trypanosomiasis, and giardiasis. Antiprotozoal drugs target specific cellular processes or structures within protozoa to inhibit their growth or survival.

Nucleic acid synthesis inhibition: Some antiprotozoals, such as pyrimethamine and sulfadoxine, target the synthesis of nucleic acids (DNA and RNA). By interfering with this process, they prevent the parasite from replicating and spreading.

Folate metabolism inhibition: Parasites rely on folate for DNA synthesis. Antiprotozoals like trimethoprim and pyrimethamine inhibit folate metabolism, disrupting parasite growth and multiplication.

Protein synthesis inhibition: Antiprotozoals like emetine and paromomycin interfere with protein synthesis by binding to ribosomes, inhibiting the translation of genetic information into proteins.

Membrane disruption: Some antiprotozoals disrupt the cell membrane of parasites. Quinine, used to treat malaria, forms complexes with heme and produces free radicals that can damage the parasite’s membrane.

Antibacterial Properties

Bacteria are prokaryotic microorganisms that cause a wide range of infections. Antibacterial drugs target specific structures or processes in bacteria to inhibit their growth or kill them.

Cell wall synthesis inhibition: Penicillin and other beta-lactam antibiotics interfere with the synthesis of the bacterial cell wall, preventing the formation of a strong and protective barrier.

Protein synthesis inhibition: Tetracycline, erythromycin, and other protein synthesis inhibitors bind to ribosomes and block the translation of genetic information into proteins, leading to bacterial growth arrest.

DNA synthesis inhibition: Quinolones, such as ciprofloxacin and levofloxacin, target bacterial DNA gyrase and topoisomerase IV, enzymes involved in DNA replication. By inhibiting these enzymes, they prevent bacterial DNA replication and growth.

Membrane disruption: Polymyxin B and other membrane-disrupting antibiotics damage the bacterial cell membrane, causing leakage of cellular contents and cell death.

Impact on Microbiome

Antimicrobial therapy can have significant effects on the human microbiome, the diverse community of microorganisms that reside in and on our bodies. Broad-spectrum antibiotics, which target a wide range of bacteria, can disrupt the delicate balance of the microbiome, leading to potential side effects such as antibiotic-associated diarrhea and Clostridium difficile infections.

It is crucial to use antimicrobial agents judiciously and only when necessary to minimize their potential impact on the microbiome and promote healthy microbial communities.
