pathogens and immunity

an agent that causes disease

molecules that trigger an immune response

Created in you own body that cause allergies

molecules that are foreign that activate an immune response

are on all cells in the body with nucleus (everything but red blood cells)

These are only found cells involved in the immune system

body attacks self cells thinking they are non-self cells

the body thinks it under attack by non-pathogenic thing (e.g pollen) causing allergic reaction

pathogen with cellular structure and does proceses living organisms do

pathogen that don’t have cell structure and do alive processes

breaking down of an infected cell

Cellular, cause disease through toxins and enzymes affecting or killing cells reproduces through binary fission

cellular, use Hyphae to ( long branching filament)(think of as tenticles) that absorb nuetrience asexual or sexual reproduction

cellular, parasite that grow from eggs sexual reproduction

cellular, parasitic or free living that take a coulpe different forms of action. sexual or asexual

Non-cellular, hijack cells and use them to replicate. they cause disease through lysis of cells, cause cancer or over stimulating immune system damaging organs.

proteins folded wrong that cause other protiens to misfold. only in mammals and only the brain? neuro structeres

DNA inside protein coat (capsid) some times surrounded by lipid envelope.

general responses carried out the same for each pathogen.

physical and chemical barriers stoping pathogens from entering

Part of animals first line of defence via normal flora limiting growth of pathogens.

Thorns, bark, waxy coating

skin, eye lashes, cillia in throat

sap(inins), toxic chemicals(bitter taste), chitinases
