Biomed I: Infectious Diseases Quiz

cause disease

carriers of pathogens (ex: animals like mosquitos)

the skin barrier is intact

used to disguise cell from immune system

help cell stick to surfaces

free from bacteria

where genes of a virus are located

protein cover that protects genome

a physical barrier that has several layers of protection

chemicals that keep pathogens in check

epithelium of the nose,gut and respriatory tract

line the intestines, one layer and prevents microbes from entering

lipid-protein coat that covers capsid

friendly bacteria

chemicals produced by the liver that kill pathogens

produce antibodies

attack infected host cells, recognize camouflaged pathogens

eat microbes and use receptors on cell surface to identify them

genetic variants of the same organism or species

membranes that line body cavities that are exposed to the external environment

path that microbe takes to travel from host to host

overall impairment of health

amount of pathogens needed to infect host

a pathogen's ability to survive, enter, and reproduce in the host

huge pandemic in 1918

world wide disease

disease caused by microbial agents

how the cell moves, can change proteins so it's not detected by immune system

helps microbe stay alive if it has unbeneficial conditions

protects cell by using layers of muiren, also protects bacteria from different climates

1.5-3.5 acidity, limits pathogens ability to infect host

contain enzymes that break down bacteria and keep cornea hydrated

epidermis,dermis,hypodermis

only vitamin your body can produce on its own, skin synthesizes it

sensory receptors on the skin

more abundant glands, found in palms, forehead and soles of your feet

less abundant glands, work around puberty, found in your armpits and groin

oil glands found everywhere but in thick skin

layer of fat mostly present in the hypodermis insulating and cushioning the skin

a yellowing of the skin signaling liver problems

165 AD, smallpox or measles, epidemic took place in Rome

14th century epidemic that killed 30-60% of European population

proteins that recognize different pathogens and mark them for destruction
