Should a spinal tap normally be clear or cloudy? - ANS Clear
Pasteurization Growth media - ANS are used to grow microorganisms; liquids; others are
more solid or gel-like. Provides nutrients, including water, various salts, a source of carbon (like
glucose), and a source of nitrogen and amino acids (like yeast extract) so microorganisms can
grow and reproduce. .
parasitology, - ANS study of parasites

, What is the name of a famous iceman that was found and what illnesses was he found with? -
ANS His name was Otzi the iceman Eggs of a parasite (trichuris trichiura) and lyme disease
basterium. He tried to treat them b cutting lesions in his flesh and burning herbs in them (look
like tattoos) and he also had a woody fruit fungus with him. Researchers think he was 5300
years old
What is one of the first examples of people thinking that diseases were communicable? -
ANS In the Bible where the Israelites are ordered to quarantine sick people and dead bodies
(shows how God was supernaturally helping them out as other civilizations around them were
not so sanitary)
How did the Romans prevent illnesses from human waste? - ANS They made massive
aqueducts that brought in fresh water and made a huge sewer called Cloaca Maxima to dump a
whole lot of nasty into the river Tiber
Who is considered the father of Western medicine and why? - ANS Hippocrates (460-370 BC)
He is credited with making the hippocratic oath and saying that diseases were not caused by
supernatural forces
bacterial cell size - ANS 1 micrometer
microbial fermentation - ANS microorganisms consume fermentable sugars and produce end
products that inhibit growth of pathogens
inoculation loop - ANS a metal rod with a small wire loop at the end, used as a swab
Bacteria - ANS single-celled organisms that lack a nucleus; prokaryotes
virus - ANS A tiny, nonliving particle that invades and then reproduces inside a living cell.
