Intro to microbiology

Microbiology

Study of lifeform that can not be seen with naked eye

What is microbiology also known as?

microbes or mircoragnisms

pathogen

microbial infectious agent (what causes the disease)

infection

pathogen multiples and spread in the body

types of infections

symptomatic & asymptotic

symptomatic infection

shows symptoms

asymptomatic infection

does not show symptoms

disease

abnormal state of health (not caused by microbes)

infectious disease

tissue damage

virulence

pathogen can quickly cause tissue damage which can lead to severe disease

microbial agent of disease and death

germs that cause diseases and could lead to death

beneficial agent

good germs to keep us heathly

pharmaceuticals

medicine

death certificate

What brings the patient to the hospital and dies from something else, the certificate will say they died from what they came in for

sepsis

an infection in the blood that can lead to sepsis, primary in hospitals, 4th leading death in the U.S.

mircobiome

all of the good germs in the body (NF)

microbiota

specific species of germs

probiotics

health benfits when ingested (seed)

dysbiosis

opens space in the body for more germs to enter

prebiotics

helps the bacteria grow

pharmaceuticals

microbes that work as medication

antibiotic production

mircobes make compounds to kill or slow down the bad mircobes

therapeutic drugs

drug treatments for infections, vaccines, and inflammation

bacteria (bacteriology)

prokaryotic, unicellular, has little DNA, small, no nucleus & organelles, complex rls with humans, fast grown rate (20-30 mins)

what is the main source of diseases

bacteria

99% of sepsis cases is from?

bacterial infection

fungi

made out of eukaryotic cells (yeast and mold)

ergosterol

fungi fat, not harmful

what does ergosterol do to the body

help stable cell membranes

anti-fungal drugs

attacks the ergosterol because they are not naturally in the human body

protozoa (parasitology)

smiley face, eukaryotic, singled cell, defined structures, has organelles

scopes of microbiology

bacteria, fungi, protozoa,helminths, viruses

gardia labia

intestine infection

plasmodium

cause malaria, rare, infects red blood cells and uses hemoglobin

viruses (virology)

small, no cells, metabolism, cytoplasm, and organelles

influenza A virus

flu, lung infection

coronavirus

covid, lung infection

norovirus

stomach flu, stomach infection

helminths (parasitology)

worms

trematodes

flukes

cestodes

tapeworm

nematodes

roundworms

immune system

defensive organ system of the body, recognize and remove the pathogen, all over body

inflammation

body’s reaction to an infection/injury

edema

swelling

organ disruption

damage tissue

sepsis in immune system

infection in blood, vessel leak, swell+low blood pressure, organ struggles

age (younger than 1 and older than 65)

immune system weakens

immunological disease/dysfunction

could be inherited, acquired, meds, cancer treatments, happens when immune system do not work properly

co-morbidties

ppl with past or current diseases are more sensitive to new ones

mutualism

microbes benefits, human benefits

commenalism

microbes benefits, no harm or benefit to human

parasitum

microbes benefits, harmful to humans

normal flora (NF)

inside and outside of body

resident NF microbiota

stays in the body for a long time, once in/on the body it do not leave, peaceful, 95%-99% of bacteria
