PY - 2009 T2 - Pharmacology for the Physical Therapist AB - Viruses are obligate intracellular parasites. That is, unlike bacteria, viruses depend on living host cells to replicate and function. Since viruses rely on the synthetic machinery of host cells, viruses can be extremely small. In many cases, the entire viral particle, or virion, consists only of nucleic acids (deoxyribonucleic acid [DNA] or ribonucleic acid [RNA]) surrounded by a protein shell, or capsid. Some viruses have an additional glycoprotein coat called an envelope.
