Reduce time to develop drugs/vaccines, improved diagnostic tests, distribution of manufacturing that can reduce shortages
34
Biotechnology dangers?
Experienced scientists becoming a threat, ability to hurt agriculture
35
Examples of confidence building measures in theBWC
submit data for BSL-4 labs, exchange information onoutbreaks, share publications, promote contacts between scientists, share events, creation of national legislation, offensive or defensive research before 1946, facilites creating vaccines
36
What activities do parties to the BWC have to reveal?
prophlyaxis, studies on pathogencitiy, virulence, diagnostic techniques, aerobiology, detection, treatment, decontamination
37
Legislation created to promote production of countermeasures?

38
How are viruses classifed?
by the hosts they prefer, the type of structure, how they reproduce, genetic material they possess, and diseases they cause
39
Virus size range
3200 bp to 800,000
40
Shapes of viruses
cylinders, round and studded, icosahedron
41
Characteristics of viruses?
not living organisms and rely on host for all functions including replication
42
What are bacteriophages?
viruses that infect bacteria that attach on the bug via receptor sites and pump genetic material into it
43
Two kinds of phages
virulent and temperate - genetic material gets copied along with host's plasmid
44
lysis
increase in phages causing the host cell to burst open, releasing more phages
45
Several functions of viruses in animal cells
produce viral proteins that have a toxic effect on host cells, interfere with protein manufacture, create new cell structures to demolish the host cell, alter the surface of the host cell so that it will be attacked by the host’s own immune system, alter the host cell’s growth cycle and turn it into a cancer cell
