Front 6

Time of colonization... Story .... Origin

Back 6

A Healthy human fetus is sterile until rupture of Protective membranes surrounding it

It begins during passage through birth canal

Front 7

Principles of Infectious diseases...

Back 7

Most of them are Initiated by colonization

Colonization : Microbe becomes established and multiplying on body Surface

Front 8

Results of microbial colonization

Back 8

1)Elimination of organism by host defenses without affecting host

2) organism become part of normal flora

3) infection in which :

A) subclinical or unapparent infection occurs > no Apparent signs or symptoms

B) infectious disease
