Organisms that cause disease

Front 2

Pathogenesis

Back 2

Pathogens means of attacking the host

Front 3

Opportunistic Infections

Infections that set in in the case of an immune defficiancy.

Front 4

Innate Immunity

Back 4

This provides the body with a first line of defense against infection. The mucosal layers and the skin act as barriers.

Front 5

Lysozyme

Back 5

a hydrolytic enzyme found in mucous secretions and in tears, is able to cleave peptidoglycan layer of the bacterial cell wall.

Front 6

Interferions

Back 6

A group of proteins produced by virus-infected cells. These have the ability to bind to nearby cells and induce a generalized antiviral state.

Front 7

Complements

Back 7

A group of proteins that float in a serum form that are in an inactive state. In the active form these proteins can degrade the membranes of pathogens

Front 8
