PATHOGENS
biological agent that causes disease or illness to its host.

There are millions of different fungal species on Earth.

They are primitive plants that inhabit our environment

Giardiasis

DISEASES:

Yeast infections

Ringworm

Athlete’s foot

Jock itch

Fungal nail infections

They cause infection when they overgrow

Contains a nucleus and other components protected by a membrane and a thick cell wall

Their structure can make them harder to kill

Some new strains of fungal infections are proving to be especially dangerous

Parasites are organisms that behave like tiny animals, living in or on a host and feeding from or at the expense of the host

Parasitic infections are more common in tropical and subtropical regions, but they can occur anywhere.

PROTOZOA: which are single-celled organisms that can live and multiply in your body

HELIMITHS: which are larger, multi-celled organisms that can live inside or outside your body and are commonly known as worms

ECTOPARASITE: which are multi-celled organisms that live on or feed off your skin, including some insects, such as ticks and mosquitos

DISEASES:

Malaria

Trichomoniasis

Lice

They are spread in several ways, including contaminated soil, water, food, and blood, as well as through sexual contact and bug bites

when the cells in your body are damaged as a result of infection and signs and symptoms of an illness appear.

They weaken the immune system

Microorganisms made of a single cell

VERY DIVERSE

Live in just about any environment

Human body

Food

DISEASES:

Staphylococcal infections

Pneumonia

Strep throat

Bacterial meningitis

Lyme disease

Tuberculosis

Some bacteria is good for our body, while some are very hurtful causing infection and disease

Bad bacteria=pathogenic bacteria

Most of the time bacteria isn't causing diseases - but the toxins that are produced by the bacteria

Your body can becomes prone to bacterial infections when your immune system is compromised. The disease state enables harmless bacteria to become pathogenic

Antibiotics are used to treat bacterial infections. Sometimes bacteria becomes resistant, making it difficult to treat.

There are thousands of species, but only one hundred cause infection and diseases
