Virology Exam #1 Properties of a virus - correct answer - Filterable agents (not retained in a filter like bacteria are) - Obligate intracellular parasites - Cannot make energy or proteins independent of a host cell (no generation of metabolic energy) - Viral components are assembled and do not replicate by "division" - Must encode any required process not provided by the host cell - Genomes may be RNA or DNA but not both - Have a naked capsid or envelope morphology Theories on how v...

Clinical VirologyCharacteristics of Viruses - correct answer Structure: Capsid, nucleo-capsid, virion and envelope Taxonomy: Classified in orders, families, genera, and species based on genome type (DNA/RNA), morphology, and presence/absence of an envelope Viral Replication: Obligate intracellular parasites, virions must absorb or attach to the cell surface, penetration, assembly, lysis Lab Diagnosis of Viral Infections - correct answer Labs can provide different levels of services; bas...

Overview of the Blood - •Blood •5000ml •Plasma •3000ml Hematocrit defined - - % of RBCs [higher value = higher viscosity = thicker blood) - Example: Polycythemia may have Hct of 60-70% Types of Blood Cells - Erythrocytes [RBCs) - - Transport O2 - Small disc shape - Lifespan = 120 days - Carry Hgb [ferrous oxide, also an acid/base buffer) - Made in the bone marrow - Iliac crest for sample in leukemia [after age 20 in the vertebrae, sternum, ribs, iliac) - Hgb Levels: 14-16g/...
