Prions

Infectious agents composed of misfolded proteins that can induce abnormal folding in normal proteins, leading to neurodegenerative diseases.

Virus

Non-living, submicroscopic agents that are typically made up of a DNA/RNA core surrounded by a protein coat. They require a host to replicate and cause various diseases

Bacteria

Single-celled prokaryotic microorganisms that can exist independently or in colonies. They have a simple structure, lacking a nucleus, and can be found in diverse environments, some of which can cause diseases.

Protists

Living microscopic single-celled eukaryotic animal-like organisms. They infect the digestive tract, blood and organs depriving the host of essential nutrients. Get it by consuming contaminated food or water.

Fungi

living multicellular eukaryotic organisms like yeast and mushrooms

Helminths

living, multicellular eukaryotic worms which deprive the host of essential nutrients.

Pathogen

The bottom layer of the skin that consists of fat that cushions muscles and bones as helps regulate body temperature.

Inflammation

when a part of the body becomes reddened, swollen or hot. Normally in reaction to infection or injury

Sepsis

the body's immune system overreacts to infection causing inflammation

Severe sepsis

organs in the body begin to malfunction, blood pressure is low and inflammation continues

Septic shock

extremely low blood pressure that doesn't respond to IV fluids

TIME principle

T- temp is higher or lower than normal

I- signs and symptoms of infection

M - mental decline

E - extremely ill

Lymph nodes
