Riketsia (Rickettsia) ialah satu genus bakterium sangat pleomorfik, tidak membentuk spora, gram-negatif, tidak motil yang boleh hadir sebagai kokus (garis pusat 0.1 μm), batang (1–4 μm panjang) atau kebenangan (10 μm panjang). Sebagai parasit dalam sel obligat, kemandirian riketsia bergantung pada kemasukan, tumbesaran, dan pembiakan di dalam sitoplasma sel perumah eukariotik (biasanya sel endotelial).[8]
