BIO immunity & pathogens

microbe

any organism that spends its whole life at the size that requires a microscope to see

Pathogen

• a disease causing agent

• EX)

  • Bacteria

  • Viruses

  • Prions

  • Fungi

Antibiotic

an agent that is made by mircoroorganism that kills/prevents the growth of other microogranism

Probiotics

microorganisms that have some health beneits when consumed

Disinfectant

a chemical agent used to destroy/inhibit the growth of microbes

Antiseptic

substance applied to living tissue/skin to reduce the possibility of infection

What is the the function of Prokaryotic?

decompose dead cells, make vitamins, protect us

Ecoli (escherichia coli)

the bacteria that lives in the colon of warm blooded animals, this is how we get food posioning, vitamin k, coliforms

What are the prokaryotic cell shapes?

cocci, bacilli, spirochetes

cocci

spherical prok

bacilli

rod shaped prok

spirochetes

long flexible prok

gram stain

a technique used to differentiate bacteria, gram+/-, gram+ is purple & simple, pink dye is gram- more complex, pink is more rough on out bodies

Bioflims

complex associations of +1 specides of proks

Bacterial plasmids

loops of DNA found in some bacteria, contains “special” genes that aren’t related to basic life functions, can be transferred from one bacteria cell to another

Antibiotic resistance

ability of a bacteria to resist the effects of medication previously used to treat them, usually via genetic mutation, antibiotic misuse, make infections harder to fight

Virus

an indecitous parasite, they arent alive, just have protein & dna theres no organelle

lytic cycle

replication cycle that kills the host cell

Lysogenic cycle

replication cycle that DOES NOT kills the host cell, attack squad
