Toxoplasmosis in cats is commonly treated with which antibiotic?

• A. Clindamycin
• B. Amoxicillin
• C. Doxycycline
• D. Metronidazole

Answer: (A)

Toxoplasmosis in cats is treated with an antibiotic that can reach inside host cells where the parasite lives and stop its replication. Clindamycin fits this need well because it concentrates in tissues and acts on the parasite’s protein synthesis machinery, effectively reducing tachyzoite replication inside cells. This makes it the preferred first-line choice for feline toxoplasmosis. Amoxicillin targets bacteria by inhibiting cell wall synthesis and doesn’t act on protozoa. Doxycycline can treat certain intracellular bacteria and some protozoa, but it’s not the standard, reliable option for feline toxoplasmosis due to slower and sometimes less consistent response. Metronidazole addresses anaerobic bacteria and some protozoa but is not reliably curative for Toxoplasma gondii in cats and can cause adverse effects.
