MCB 2004 EXAM 1 VERIFIED STUDY GUIDE
koch's postulates - Answers - sequence of experimental dsteps for directly relating a
specific microbe to a specific disease: Koch proved that bacterium causes anthrax and
provided the experimental steps Koch's postulates to prove that a specific microbe
causes a specific disease
o Microorganism must be found in all cases of the disease
o It must be isolated from the host and grown in a pure culture
o It must reproduce the orginal disease when injected into a susceptible host
o It must be found in the experimental host so infected - Answers - 4 koch postulates
• milli meteres 10^-3 = 1 meter
• micro 10^-6 = 1 meter
• nano 10^-9 = 1 meter - Answers - converting between units
reject or rise your hypothesis - Answers - o If the data from your experiment does not fit
you hypothesis you ?
Archea and bacteria
• eukaryotes - algae plants, protest, fungi animals
viruses has DNA in nuclease - Answers - o which is a prokaryote?
• Introduction of microbe into healthy individual makes individual sick - Answers - o
which of Koch's postulates is not ethical to test in humans?
pastaeur - Answers - o Who disproved spontaneous generation of microbes?
penicillin - Answers - o The first naturally occurring antibiotic to be isolated was?
viruses - Answers - o Which type of orangisms is not a cell?
• Double stranded DNA - Answers - o All cellular organisms have genetic material
composed of
• Anabolism
• Catabolism - is breaking down - Answers - o Pathways of chemical synthesis reactions
in living orangisms that construct larger molecules from smaller molecules are called
• Fructose
• Cellulose, dextran glycogen, and starch all are - Answers - what is not a poly sac?
phospholipids - Answers - o Membranes are composed of ?
• Pasteur - swan neck flask growing bacteria
, • Disporved spontaneous generation - that organisms arise from nothing
o He saw that if flask were closed and not exposed to anything no microbes would grow
o Pasteurization - application of high heat for a short time - Answers - what did pasteaur
disprove
• was discovered by flemming
• was the first naturally occurring antibiotic and is made by a fungus and was noted that
it killed staphylococcus aureus - Answers - discovery of penicillin
spanish flu - Answers - o 1918
o caused by influenze virus and killed 40-50 million people world wide
influenza A virus - Answers - o primarily in waterfowl and poultry
o sustained human to human transmission has NOT occurred
severe acute respiratory syndrome SARS - Answers - o Occued in 2002-2003
o Person to person transmission
o SARS associated coronavirus (any of a group of RNA viruses that cuase a variety of
disease in humans)
• MERS - also a coronavirus
ebola hemorrhagic fever - Answers - o Ebola vius
o Causes fever, hemorrhaging, and blood clotting
o First identified near ebola river - congo
o Outbreaks every few years
• Major urban outbreaks last 2 years in Liberia , guinea and sierra leone
west nile virus - Answers - o Causes encephalitis
o First diagnosed in the west nile region of Uganda, but appeared in new york city in
1999
o In nonmigratory birds in 47 states
human immunodefiecieny virus (HIV) causes AIDS - Answers - o 1981
o world wide epidemic in 2011 - 34 million ppl with aids
o almost 35 million have died of aids since identification
o sexually transmitted affecting males and females
• also transmitted by infected blood products and medical equipment
o HAART - highly active anti retroviral therapy savs lives of AIDS
• Mad cow disease (bovine spongiform encephalopathy) - Answers - o Prion - misfolded
protein that can cause other proteins to misfold by contact
• Also cause creutzfedlt jakob disease (CJD)
New variant in CJD in humans is related to cattle fed sheep offal for protein
• Escherichia Coli O157:H7 (bacterial) - Answers - o Strain of EHEC
o Toxin producing ecoli
