Biomed 3.1 (+ some terms from other test that will be on this one)

investigates microorganisms and bacteria

observing bacterial colony

dye bacteria using crystal violet

what cells look like under the microscope

bacteria dividing

organizing observations and analyzations

test tube, petri dish BOTH nutrient agar — called slant on test tubes

procedure in sterile conditions

to isolate the bacteria on a petri dish - finding individual colonies

what a bacteria culture looks like large scale w naked eye - looking for color, shape

bacteria under the microscope

purple

pink

group/clusters

circular

worm like (elongated no circular)

chain formation

double chain

virus and protists

agar, nutrient broth, substance in which something is growing

to dilute the bacteria each time

to see the bacteria clearer

so that they crystal violet stays on the gram positive

so the gram negative becomes transparent again

so that gram negative turns pink to see clearer under the microscope

Gram-positive bacteria have a thick peptidoglycan layer and stain purple, while gram-negative bacteria have a thin peptidoglycan layer and stain pink.

Bacteria duplicate and cause the cells to compete for resources, and release toxins into the cells, could also disrupt immune reaction, especially GRAM NEGATIVE

Antibiotic resistance occurs when bacteria adapt and become immune to the effects of antibiotics, making the medications ineffective in treating infections.

lypopolysaccharide - HYDROPHOBIC

colorless gram-negative bacteria, making them difficult to distinguish from the background.

so the condensation does not spread on the agar, ruining the isolation of colonies

The primary goal of a computer scientist is to solve complex problems using computational techniques and algorithms.

someone who studies viruses

study trends & health issues, such as chronic illness and disease outbreaks by gathering info

comes through open holes (mouth, ears, nose wounds), disrupts cella and organ functions, prevented by vaccines or antibiotics, example of disease is tuberculosis

spores of fungi, causes tissue damage, diagnosed through the the blood, treated through antifungals, example is athletes foot

consumption of contaminated foods, causes tissue or organ damage, cures w deworming meds, example is tapeworms

meat, med equipment, causes brain damage, meds can slow but no cure, example is jakob disease

ingestion of feces or raw foods, damage to digestive tract, tissues, or organs, prevented through anti-protozoal meds, example is giardiasis

contracted through touch, saliva, blood, infects other cells, damages host cells and tissues are destroyed, vaccines prevent, examples are flu influenza

Virus infects cells by attaching to host cell, injecting genetic material, replicating inside cell, and releasing new viruses to infect other cells

sickness, either temporary or permanent through transmission or genetically

Infections are caused by harmful microorganisms invading the body, leading to illness or disease. They can be viral, bacterial, fungal, or parasitic.

infectetious agents of disease

comes from parents or mutated

spread through other people

place that holds the disease

place for disease to incubate, ready to spread

vulnerable to disease

long term condition

what they are born with

a hospital aquired infection (HAI)

perpetually present in a community

comes and goes in seasons

a sudden increase in occurences of disease

rapidly spread to a large # of people

an epidemic that spread across several countries

skin and mucus, as well as tears and stomach acid. White blood cells alert and rush to the pathogens, consuming whatever it can. Alerts B cells and T cells

T cells arrive, destroying what they can. B cells are alerted and create anti bodies to rapidly and specifically kill the infection

adaptive immunity from b cells recognizing the pathogen and making an antibody

defensive system what you are born with

reacts to new and specific antigens in the body (flu, covid)
