Document Summary

Nucleic acid (either dna or rna- never both) surrounded by protein shell (capsid) Attach, inject nucleic acid (penetration), highjack synthetic processes inside cells to make more viruses, package, get out while going is good . Handwashing- more bacteria after washing hands since the bacteria in the deeper layers are exposed- only after washing for 20-30 seconds are hands cleaner after wash. Myeloid stem cell: erythrocyte, neutrophil, macrophage. Lymphoid stem cell: nk cell, thymus- th1, th2, ctl, b cell: plasma cell, antibody formation. Research indicates that: hijacking human plasminogen from blood, attach to surface and activate it into protease. Good for spreading: strep becomes infected by bacteriophage, which has gene encoding (erythrogenic toxins for enzyme allowing bacteria to escape entrapment and killing by wbcs) Gram stain: flood slide with crystal or gentian violet, wash with running tap water, stains everything, whether gram + or , flood with gram"s iodine (wash with water, allows crystal violet to bind to peptidoglycan layer b.
