pathogens, bacteria and fungi Flashcards
ways pathogens are spread
skin contact
animals to people
contact with feces
the 2 types of direct transmission
Direct contact-physical contact between an infected person
Droplet spread- contact with droplets from an infected person’s cough or sneeze.
types of indirect transmission
Airborne-transmitted through small respiratory droplets
Vehicleborne-occurs when a substance carries an infectious agent to a new host.
vectorborne-occurs when a living organism carries an infectious agent on its body (mechanical) or as an infection host itself (biological), to a new host.
non communicable disease
type of acquired disease that is not caused by a pathogen and not contagious-usually lasts a long time(chronic)
non-communicable disease consist of/ example
Cardiovascular disease
Cancers
respiratory disease
Metabolic diseases (
how much of the diseases in australia are non communicable
71%
Types of pathogens
Bacteria
Fungi
Viruses
Bacteria
are prokaryotic organisms
what is scientficially conisdered first form of life on earth
Bactiera
What kind of forms does bacteria come in
good and bad(probiotics vs pathogenic)
What does bacteria use for protection
bacteria has a slimy capsule to protect itself from white cells
What does bacteria have that fungi doesnt
some bacteria has a tail , some but not all
Prokaryotes
cells that have no membrane bound nucleus
Eukaryotes
cells that have a nucleus
Fungi
are eukaryotic organisms
What are fungi more related to
more closely related to the animal
kingdom than the plant kingdom.
What does fungi not have
chlorophyll or chloroplast
What is fungi classified as
decomposer or parasite
What can fungi be used for
used to make medicine
How does coloured fungi effect humans and animals
toxic to animals and mammals
endospores
an asexual spore that allow bacteria to survive in hostile environments
antigen
any substance that causes your immune system to produce antibodies against it.
prion
a type of protein that can trigger normal proteins in the brain to fold abnormally
endo vs ecto parasite
Endoparasites live inside an organism, and ectoparasites live on the surface of the host.
Where do we get gut bacteria from?
parent-to-child transmission and transfer from food, water, and other environmental sources.
Are any two people’s gut microbiomes identical?
No, it depends on many factors, making everyone’s microbiome different.
. Suggest factors that influence the composition of our gut microbiota over our lifetime.
disease
antibiotics
prebiotics and probiotics
example of types of indirect transmission
airborne-chickenpox
vehicle borne-disease in foods
vector borne-Malaria
protist
eukaryotic organism that is not an animal, plant, or fungus.
differenc between protist and fungi
protist are uni celluar
fungi ar emutlicelluar
difference between non celluar and celluar pathogens
celluar pathogens are livingwhilst non celluar pathogens are not living
what is an example of a suitable substance used to kill pathogens on a tabletop
bleach
STI/STDS are caused by
bacteria, fungus and viruses
what is not a way that pathogens can be introduced to an orgnaism
bacteria sitting on intact skin
antigen-antibody complex
molecule formed from the binding of multiple antigens to antibodies.
